Cross format compatibility. Will a Voigtlander Nokton 58mm f1.4 SLIIs Nikon mount lens cover the full frame of the medium format Fuji 50Sii? Let's walk around during the heat of the day and find out...

 

Walking around the West Campus area and walking around on the University of Texas at Austin campus.

 At least on campus there is ample shade....

When I got the Fujifilm 50Sii from my friend it came complete with a Tech-Art Nikon F to GFX lens adapter. Just so happens that I have two Voigtlander lenses in Nikon mounts; the 58mm f1.4 Nokton and the 40mm f2.0 Ultron. Both are very, very good lenses when used for their "native" format = 35mm. I wondered if either of the lenses would project a big enough image circle to actually cover the full width and height of the 33mm by 44mm sensor in the MF camera. 

Today I decided to find out. Well, I decided to find out how the 58mm performed. I'll try the 40mm next time.

Here's the TB:DR (too bored, didn't read) version: The lens has a very small but very severe bit of vignetting in all four corners. I'd be more concerned if the vignetting occurred in just one corner...or two. Stopping down makes the vignetting smaller in size but denser in its core. Focusing close reduces the size of the vignette. 

At wider apertures the corners and about 5% of the edges of the frame are soft. Stopping down to f5.6 the whole frame (except for the far corners) gets nice and sharp. I think it's a laudable performance since we're using the lens here far outside its design parameters. For portrait work it would be fine. Hate the vignetting? A slight crop into the frame will fix that right up. 

The focus peaking in the Fuji 50Sii works really well. The lens focuses really well. I am now considering adding the 90mm f2.8 Voigtlander lens in a Nikon mount to round out the mix. Nothing certain yet. Hesitating because I know myself and if I end up liking and keeping the Fuji I'll probably go out at some point and buy the vaunted 110mm f2.0. But with my luck I'll decide to make the purchase the day after it goes off sale. If I push "buy" today it's $2200. If I wait it will be four or five hundred dollars more. Another first world dilemma to worry about...

Still f-ing hot here. Not getting better. Cabin fever sinking in every day after lunch....

Take a gander through the images. From what I can see both the camera and the lens are worth having. Keep in mind that my intention is to use the Voigtlander 40 and 58  (and other 35mm format lenses) with the camera set to the square format. In that configuration there is no vignetting and no noticeable softness in the corners.  Yay!

What Kind of Craziness have I Embarked on Today?



I've been made aware over the years that many of you are very, very organized and that your back-up strategy for your digital files is well nigh flawless. I'm proud of you all and wish I could hand out gold stars personally. I am embarrassed to admit that my back-up strategy has more or less fallen apart and I depend more on endless duplication across an aging brigade of weathered, external hard drives that range from ancient, one terabyte (original) firewire and USB-1 drives, to little bus-powered "pocket" drives, all the way up to nearly modern, USB-3, four Terabyte drives. 

Nearly all of them have names and most of them have swatches of white tape on them to label them both by name and by the year they were first introduced to service on my jangly and jumble-wired desktop. Some of the dates on them are starting to become....embarrassing.

In photographic caveman days my back-up strategy for client photographic files was pretty straightforward; at the beginning of the year I'd head to Office Depot and get a big binder that held a couple hundred CDs or DVDs. When I finished a job I'd make two copies of the material (raw files and finished files X2) on DVD's and put them into that year's binder. The binder would sit on the Metro shelving in the studio, along with last year's binder, and the year previous to that. I would also have a copy of the files on two different hard drives. But, when budgets were tight I'd only splurge on one new hard drive at a time, and only when one of the older ones either crapped out got too full. 

At some point about six or seven years ago camera files got much bigger, I got more indiscriminate in my shooting style (more is better?), and I tossed fewer non-selects (because editing takes time....). Since a job shot with a camera generating 42 or 50 megapixel raw files takes a bunch more space than the old 12 megapixel, steam-powered camera files it became more and more impractical to try sitting around burning multiple multiples of DVDs for each project. And hard drives started filling up quicker as well. 

Now I just keep a DVD drive around for the times when I need or want to access files stored and filed on DVDs. Or to impress children who have only ever known about streaming media. Nothing gets burned anymore because the first hour of shooting, in many projects, would fill up a couple of disks and time is money. Or, at least, billable time is money. 

My current methods are these: Before I shoot a project I let the client know what my workflow is. I tell them that they'll receive final files and that they are responsible for storing, archiving and protecting these files for future use. Not me. I'll let them know that I'll try to keep the files safe but since I don't personally own a hard drive company there's no way I can guarantee with any certainty that the files will always survive and be available a decade later. In the last year I started letting clients know, in advance, that we only agree to try to keep the files safely stored for one calendar year. After that the availability of the files is totally up to them. This isn't a film world anymore. Everything moves faster. Images have a shorter shelf life and I have fewer opportunities to re-sell or re-license images. 

Once I do the job for a client I ingest the images into my system via Lightroom and have Lightroom write the files (pared down keepers) to two different hard drives. I work on the files mostly in Lightroom and output them as highest resolution, full size Jpegs. If something needs work in PhotoShop I do that and then put the resulting files (as Jpegs) in to the Jpeg folder. Then, all of these Jpeg files get uploaded to Smugmug.com and put into individual galleries. The galleries are nested into logically named and sorted folders. 

The clients get access to the galleries, and, if I've contracted to allow them to use the images for a long time, across many media, then they also get a download password that allows them to endlessly pull big, nice, color corrected Jpegs right off their gallery. I could be out of the office for a year and as long as I keep paying Smugmug.com for their service the clients will be able to access their galleries. I currently have about half a million images in folders and galleries on the site and the oldest folder is from 2004. It still works. It's still active and accessible. 

The real reason I adopted this strategy was the dropping price and increasing speed of broadband web access. I can finish a job with 10 or 20 Gb of files, hit the upload screen, go for coffee, and chances are the entire gallery will be up and ready by the time I've finished bullshitting with friends and acquaintances at the coffee shop. It's nice to know that the files are stored off site and, in all probability, a local lightning storm or a random meteor strike that wipes out my desktop system won't wipe out my image inventory of client work. I also keep many galleries of family stuff there as well...

But....but...I still WANT to have those files saved as raws and Jpegs in a local storage device as well. Because....I think that's what we've been led to believe... So, I have a current collection of eight hard drives on the desk and a wide filing cabinet drawer with another dozen or so older drives sitting right next to the desk (don't know how I'm going to access a couple of the oldest SCSI drives....but three or four times a year I take a day to spin everything up). 

When I tallied the active desktop storage selection recently most of them were filling up fast and many of them were getting up there in HD years (which are even quicker than dog years). My oldest current desktop veteran is a 1 TB drive that was put into service one year short of a decade ago. Its demise is inevitable. At least that's what the digi-savants tell me. 

So, when I upgraded to the new iMac Pro I decided to also start the year out fresh by bringing in two, new hard drives; almost the same way in which would go out and buy a new binder each year. Since the files from the two Panasonic Lumix S1R cameras aren't going on a diet any time soon I decided I needed to get bigger drives this time. I bought two 10 terabyte drives which I have earmarked for all 2020 files on the desktop. Each folder of files is duplicated across both hard drives. Seems like a good plan, especially in concert with my ongoing uploads to Smugmug.com. 

I formatted both new drives today and then went in searching for all the quasi mission critical files that sat on the oldest drive. I thought I could copy them over to the new drives, just in case... you know....entropy. When I plowed through the content on the oldest disk I realized how much sheer crap I save on my disks. There were folders filled with raw files of obsolete products from companies that had long since gone bankrupt and exited the market. Those didn't need to be transferred, they needed to be dragged to the trash. When I finally edited down to the "must have" keepers on that drive I ended up transferring less than 50 GBs of work files. 

Now I'm plowing through each additional legacy drive to see just how much absolutely worthless crap I've been paying to keep around on my desktop for all these years. I'm learning that so much of what I've shot over the last decade is filler and exploratory stuff but not much that's valuable and dear. I should have learned this a year and a half ago when I had to clean out my parents' house of 40 years worth of stuff that needed to make the trip to the trash can long ago. 

Obviously, the two new 10 terabyte drives are NOT SSDs. Not even Warren Buffet can justify the cost of multiple 10 terabyte SSD drives used just for storage and occasional access. But they are USB 3 drives and those are much faster and less doggy than the USB-2 drives and the 2's and the 3's run circles around the very old, original USB-1 drive. 

I do have a couple of external 256 GB SSDs and I use them a lot now to load full of folders and work on files in concert with the SSD drive in the new computer. It's like working at hyperspeed compared to my old ways. I guess keeping up with some technology is prudent. It sure is nice to finish projects in one quarter the time we spent just last year. Go 2020!!!

(just above) a mission critical part of our workflow philosophy revolves around the access to and utilization of coffee 3.0. Made fresh with steamed milk and delivered in an enclosure that retards thermal decay. It doesn't make the machines run faster, it only enhances my typing speed and accuracy...

Ben and Studio Dog visiting relatives at Christmas. The uploading of family images to our online storage sure makes it easier to find photos I want to share with family and friends. Can't imagine now having to dig into a cardboard box to find a folder full of black and white negatives and then heading into the darkroom to print up a couple 5x7's for someone. Not for free, at any rate. And, I'd have to build a new darkroom. Never going to happen. Not while these disks keep working. 

Next up, on my agenda, is to revisit printing my own stuff here. Stay tuned? Or largely ignore?

A. Molitor: How's the LED Light search going? 

a caution to readers: Please don't tell me how I can save thousands and thousands of dollars by building my own hard drives or by building my own computers from scratch. I tried that with a Ferrari kit once and it was a f---ing disaster and blew up in the driveway...... YMMV.

Everybody trumpets their favorite camera of the year but I didn't read much about everybody's favorite cheap lights last year. Here's my favorite 2019 purchases and my favorite 2020 purchase. Go Lights!!!

Don't you just love it when the box shows up from some photographic retailer and everything inside has arrived without damage? I sure do. I think I buy as many lights in a given year as I do cameras. I rarely get emotionally attached to lights but I'm of the belief that good lighting is as important to many photographs as having the right camera or the hippest lens. I got one box this year and it had my "2020 Electronic Flash of the Year" in it. I know I'm a little early but patience was never my strong suit....

But before I unveil my current champ of low cost lighting for 2020 I'd like to call out my favorite two purchases of 2019.

First up is the Godox SK 400 mark ii. A fancy name for a dirt cheap monolight from a fairly well trusted brand. I bought this in the middle of the year when a set-up shoot on a dark stage with 60 foot ceilings convinced me that modeling lights that would stay on constantly were not a luxury but a mission critical feature when it comes to focusing in dark spaces. No matter how powerful your battery powered flash unit might be pretty much all of those lumens are wasted if your AF won't lock or you can can't see where that point of sharp focus is when manually focusing your image. 

I have three battery powered monolights, each with its own LED modeling light, but the issue with them is that the modeling lights are dim and only stay lit for 30 seconds. I guess it's a battery saving "feature" but it makes using them in dark environments really, really tough. After a bout of guess focusing, and having my assistant stand by one of the lights poking the modeling light button every half minute, I drove to Precision camera to check out the options. The least expensive, but still capable, electronic flash I found was the Godox SK 400 ii. It's got a metal body, allows for a wide range of Godox triggering options, has a 150 watt modeling light, recycles quickly, even at full power, takes Bowens accessories and, best of all, is only $139. I immediately bought one.  I thought it might not stand up to wear and tear but we're going on to about 60 projects on which the SK 400 has been the main light so I think I've already gotten my money's worth out of it, and it still seems pristine and very reliable. It was my best flash purchase of 2019.

The other "Best Cheap Light of 2019" was, without a doubt, the Godox SL 60 W. It's an LED lighting instrument that kicks out 60 watts of clean LED lighting from a COB LED that is about one inch by one inch across, which means it does a much better job giving me hard edges than an LED panel light. This guy also takes Bowens accessories, has a very quiet built-in cooling fan and a very nice LCD read out on the back. You can go from 10% to full power with the nice, big dial on the back of the unit, in very fine little increments, which makes it very easy to control. 

At around $139 for this unit, with a 7 inch reflector and a set of four way barn doors, I was very, very skeptical. I had a hard time believing it would be any good at all. But I thought I'd give it a try and ordered one to try out around the studio. After I had the light for about a week I dragged out the credit card and bought two more of them. They've been wonderful for video projects and when not in commercial use I bounce one off the office ceiling for a nice, soft and color correct office light source. 

I love these lights and love the price even more. Sure, you might need more power for bigger projects, but within their design parameters they do a great job. Especially for the price. Want to stop down more? Lower your shutter speed or turn up your ISO. Godox makes more powerful units but they get big, heavy and expensive pretty quickly and you only gain a stop for every doubling of power and price. I might get one bigger unit but so far I haven't felt the need to progress beyond these bargain bad boys. Easily may favorite continuous light of 2019.

Here's what the back panel of the SL60 W LED light looks like. 
Nice and uncluttered and, yes, you can use it with a supplied remote; though all you 
can do it turn the power up and down. The light is one color temperature= 5600K.

But, that was last year. What have I done for me lately? 

After last year's black floor, black stage, black ceiling set-up shoot fiasco (not to worry, we pulled it off --- by the skin of my teeth...) I decided I needed more cheap studio flashes with built-in, continuous (and relatively powerful) modeling lights so I went to Precision Camera looking for a couple more SK 400 mk2's. End of the year....Inventory in flux....no available stock and no chance of getting the SK's in before the middle to the end of the month. 

So I went home and dialed up the online retailers, knowing I'd be able to source the Godox flash from one of them them. But when I hit the product pages I noticed a new light from Godox that was smaller, lighter and even less expensive than the SK 400ii. In fact, there were two models; the MS300 and MS200, both from Godox. A bit of reading let me know that the model numbers refer to the watt second rating of each light. 

Since the only specification that was different between the two lights was the power rating, and the price difference between the two was a measly $10 I opted to order two of the MS300s. It was ordered from Amazon.com so I figured that if I didn't like something about the lights I could always send them back for a refund. They arrived in nice, well designed (from an aesthetic/advertising perspective) boxes and come only with the body of the flash (with flash tube), the modeling lamp (which you must install), a power cord, and a rugged cover to protect the flash tube and modeling light when traveling. They do not come with a reflector. 

Not to worry, the vendor had a special offer; you only needed to click on the optional reflector and it would included free of charge. 

The construction of the MS300 lights is almost all plastic, including the stand mount and tensioning control for tilting the flash. The receptor ring for Bowens accessories attachment is metal and, honestly, the plastic parts seem like they are well made and will stand up to normal, conscientious use. You won't be able to throw them, unprotected, onto the bed of an old truck but if you generally take care of stuff you'll be fine. 

The lights can be triggered by most of the recent and current Godox radio triggers and some of the triggers (XT-1, for sure) can also be used to control the power settings. If you don't use radio triggers the lights come with built in optical slaves which can be triggered by a separate flash. The modeling light controls allow for manual control, proportional ratio, and off. There's a recycle beep that lets you know when the unit has recycled, but you can turn this off, if it bugs you. At full power it takes about 1.8 seconds to recycle. Not quite as speedy as the SK400 ii but perfectly adequate for most uses.

The one thing the experienced user and beginner of modern flashes alike needs to know, about this model, is that there is no "auto power dump" mechanism. What that means is that when you have the flash set for high power, say, 1/2 power, and you turn it down to a lower power like 1/16th, you'll need to fire a frame or hit the test button to get rid of the excess power in the capacitors. Old timers will remember this from the days of big "pack and head" systems but users of many other modern studio flashes will not be familiar with the idea of "dumping the power" to get to that lower power setting. Many more expensive flashes do this for you automatically as you turn down the power.

So, I ended up with two 300 watt second flash units, complete with internal cooling fans and all the stuff a studio photographer might want, along with two umbrella reflectors for the princely sum of $218. Or $109 each. At this price you could almost consider them disposable. 

MS300 back panel.

big modeling light? check!

Since they don't come in an array of bright, tacky colors and they don't have giant illustrations of insects on the side of the product housings, there's little chance clients will think one way or another about your choice of lights. So long as they keep flashing on command. Three of these would make a great starter kit for a financially struggling photographer while the well-heeled practitioner might even consider them to be "disposable."  Consider this, if this light put your checked luggage over your limit you might be forced to choose between a $109 light or a $140 luggage charge. Leaving the light behind would be $31 less painful. 

My take?

Need some flashes with good modeling lights? Don't want to invest a lot of money?

Start here.

And that's why, unless something more fantastic comes along these pups are already my "Cheap Ass Lights of 2020."

What do you do when you've flown on an overnight flight and you get to your destination in the morning all jet-lagged? You go out and shoot.


I love to travel but I seem to be more prone to "arrival" jet lag than a lot of people. Even in my 20's I would arrive in an exciting city with one desire... find a hotel room and crash. Hard.

But if you do that your sleep pattern gets all screwed up and you wake up in the middle of the evening hungry and circadianly confused. It never worked well for me.

Now, when I travel, I make a point to dump my luggage at whatever hotel I've booked, grab my camera and a wad of cash, and head out the door to walk through my destination city and take photographs. I allow myself to sink into the flow of the streets like an old man lowering himself into a hot bath.

This image (above) was taken on one of my trips to Paris. I was traveling alone (yes, it is possible to take a shooting vacation solo, even if one is married, and I highly recommend doing so for photographers...) and hit Paris on a warm, Fall day. I was photographing at the time with Canon EOS film cameras (EOS 1n) and I was dragging along an 85mm f1.2, a 20-35mm f2.8 and a 50mm f1.4. All the cameras were loaded with Agfa film of one sort or another. My preference then was for the ISO 100 Agfapan APX but I also carried around rolls of ISO 400 as well. In a second camera body I was shooting Agfacolor Portrait film, a nice, ISO 160 film with a long tonal range and graced with the smoothest of gradients.

As I walked along one of the parks I passed by a large fountain and was amused to find people sleeping on the ground around it. In Texas one rarely sleeps on the ground for fear of ticks, scorpions, fleas and other critters. But Parisians are brave and hearty and omni-nap-ready.

I snapped a few frames and moved on but later something about the image sitting on one of hundreds of contact sheets from the trip caught my attention and I printed it large (16x20) to see why I was interested. I haven't gotten to any sort of final understanding but I"m still interested in the image. I recently put it up on the wall. Maybe it's just that it reminds me of how good it feels to take naps.

The shooting vacation was successful, did not impact my marriage, and helped me retain a certain wonderment and attraction to the process of making photographs. A "booster shot" as it were...

One night at one theater then the next night at another. Bag of mini-cams in tow. ISO and mixed color insanity.

Sony RX10 at 3200 ISO.

When we last left off the chairman of the Visual Science Lab had just written about a lovely evening at the theater shooting an hilarious but traditionally produced play called, In the Room Next Door. The folks at Zach Theater were rehearsed to the nth degree and the production staff were as flawless and accurate as a computer.  And not just a generic computer....a really good computer. Go see that essay (which is a paean to the RX10) here: http://visualsciencelab.blogspot.com/2014/01/my-theatrical-test-of-sony-rx10-and.html

Well, yesterday I went to a different kind of theater production. No less fun but where the production the night before was perfectly regimented yesterday's fare was all about improvisation and on the fly, on the stage direction. The production was: The Bowie Project: A Rock and Roll Soundpainting. And you can read more about it in the Austin Chronicle, here: http://www.austinchronicle.com/arts/2014-01-31/the-bowie-project-a-rock-and-roll-soundpainting/

I was pre-recession busy yesterday with raw post processing in the morning, some accounting for Ben's college apps over lunch and a bunch of portrait retouching for a large medical practice for the first half of the afternoon. I remembered (almost at the last minute: thanks, iCal!!!) that I'd promised my friend, Colin, that I'd photograph the final dress rehearsal for his project (The David Bowie Soundpainting) and I needed to be right in the middle of downtown in less than half an hour.

Fortunately it's VSL policy to charge batteries and back up cards the minute we walk into the studio from assignment so the cameras were packed and ready to go. One Sony RX10, two Panasonic GH3s and a couple of fun lenses for the m4:3 camera. Should have just left it at home since the RX10 worked charmingly.

So, here's the deal. The Bowie play is completely improv. There's no script. There are snippets of choreography. There is a modern dance company involved. A Bowie singer. A rock band. A guy who let the fog machine run wild and two guys named Steve who loved playing with all of the cyberlights and catwalk mounted gelled spots---sometimes all at the same time. The direction? Shoot whatever you want from wherever you want. The play will last for between about 45 minutes to maybe 70 minutes. It might be longer. There's no intermission. Go!

I love most of David Bowie's music and it's always fun to see entertainers engaged in pure play so I just went for it. Here's a selection.....
