A brief review of a lens you probably would love to have for your Panasonic or Olympus 4:3rds camera.

I think it's funny how we pretend that optical manufacturers only really figured out how to make good camera lenses very recently.  That computerized optical design only arrived in tandem with digital imaging and how constant optical upgrades are now de rigueur.  Is the Canon 70-200mm II IS L really that much better than it's predecessor or have Canon learned how to tweak its design parameters to favor perceived sharpness and contrast over total resolution and longer tonal range?  The truth is that almost every advance has been conceived and conjured into existence to lower production costs and keep quality control manageable.  The better the lens the more hand assembly, and sample by sample tweaking, occurs.  And if you want to see the true cost of building state of the art lenses;  lenses that have price as a smaller part of the creation equation you need only look to Leica and Zeiss.  While you may not value or need the final 5% or 2% of quality over your Canon, Nikon or whatever plastic lens it's an inescapable fact that there are very few manufacturers left who offer "better than required for profitable sales" quality.

And that brings me to the latest frenzy over lenses for the Olympus and Panasonic mmc's (mini-mirrorless cameras).  The two lenses I've watched take off in the current market are Olympus's 45mm 1.8 and Panasonic's Leica 25mm 1.4.  I've played with them both and they are excellent.  And they are a good start for the systems if they want to garner widespread acceptance.  But in truth, with the older lenses stopped down one stop, the modern lenses are just about equal with the lenses Olympus was making for their Pen F film camera system over forty years ago.  Even in the late 1960's there were computers that could be used to create very good optical designs and, more importantly, there were craftspeople who could "customize" the performance of each lens they assembled.  In many parts of the manufacturing process a craftsperson could eyeball an exact fitting that guaranteed the highest performance.  Today's factory produced lenses have "tolerance targets" for their plastic mounted lens element and group modules.  Fitting into the window of tolerance makes the lens "good enough" for sale.  Not as good as it could be based on the theoretical designs!  Just good enough so that most customers who buy one won't bother to complain or will instead blame their own photography techniques.

I got a used, Olympus 150mm f4 Pen F lens sometime in the late 1980's.  I put it on a Pen film camera (what else could I use it for back then?) and tried some hand held shots.  They didn't seem amazingly sharp to me and I didn't use long lenses much so I stuck it in the drawer and was glad to have the lens because it rounded out my collection of Pen gear.

But recently, on the occasion of getting a new lens adapter for the new Pen EP3,  I decided to give the lens another try.  I mounted it on the camera, set the IS menu manually to IS mode 1 and dialed in 150mm as the focal length and I headed downtown to shoot some stuff that might help me make a better evaluation.  Here's what I learned:  1.  Image stabilization makes a lot of difference in handholding longer lenses.  I'm presuming I could do even better with a tripod but it's a good compromise between mortal and godlike performance.  2.  Single focal length telephotos don't get less sharp at their longest focal length, like longer zooms. 3.  The real promise of m4:3rds is in the enhancement of usability through size and weight reduction.  Good for the cameras, even better for the lenses.  With the 2X increase in equivalent focal length you really can enjoy the pull of a long lens without popping those lower vertebrae into the painful and queasy zone.

These images are straight out of the camera Jpegs and, if I had wanted to be disingenuous, and make my point about the quality of older lenses more obvious, I could have run them through some post processing to increase the contrast and some add some selective saturations, perhaps sharpen up the edges.  But I'm happy with the way they look as raw material.

I think we've seen a sea change in lens design.  It's analogous to what happened in color film in the ten years before the mass market for film crashed.  Film manufacturers discovered that most users loved hot saturation and harder contrast in their images.  It was more............obvious.  So they started to pump up the eye candy volume.  We thought the knobs on original Velvia slide film went up to ten but on the newer films you could turn the volume up to fifteen (a nod to the movie, Spinal Tap).  While the films were no longer even remotely faithful renderings to the original scenes the same people who like monster trucks, Big Macs and now, full bore HDR, fell in love with the miracle of MORE COLOR.  Eventually Kodak and Fuji had to issue specialty films for the professional market with the color and contrast dialed back down so professional photographers could make neutral and accurate images for product ads.  And less aggressive films were also introduced for portrait photographers once they found out that contrasty and saturated are two things that DON'T flatter most skin.

So, in lens design, given lower resolutions from the last three generations of digital imagers, coupled with acutance robbing anti-aliasing filters, camera makers started creating lenses that added snap and sparkle back in at the expense of longer tonal ranging and high resolution rendering.  You can design a lens for high resolution or high contrast but not necessarily both.  Nearly every lens is a compromise between those parameters.  Another change has been the push to even out lens performance over the frame.  Again, there are two design philosophies in conflict.  The first philosophy says that most images are of three dimensional objects and 2/3rds of images created in the U.S. are of people in or near the centers of the frames.  Lens makers can optimize for center sharpness and let natural geometry takes its course or, with the use of additional (contrast robbing) elements they can even out sharpness over the entire frame to meet the theoretical needs of a generation of number worshippers.

While even-ness is important for tilt shift lenses and macro lenses it can be completely counter productive for many day to day uses.  But I guess this is fodder for another discussion at another time.  Suffice it to say that lenses designed in the 1960's and 1970's were based more on actual use parameters since most people weren't sitting in front of monitors doing "pixel evaluations" instead of shooting and printing.  But I will end by saying that so many of the attributes we admire in the work of legendary photographers have to do with design decisions made in the glass labs and lens design labs by engineers who were far less encumbered by the current strait-jacketed, tunnel vision of marketing teams.  And we are the poorer for it.  

Do I like the 150mm lens for the Pen F?  Yes.  I like the feel of the all metal construction.  I like being able to turn the well damped, click stopped aperture ring.   And I love being able to focus the lens by hand and have a focus throw created with the human hand and brain considered.  Couple that with well made glass that doesn't suffer from chromatic aberrations and I think we've found a nice, long lens to use with the Pens of today.  But look for yourself.

Shooting A Dress Rehearsal with the tiny Nikon and the Pens....

I wanted to see how the two mirrorless systems I've been playing with handle the "real world" of Kirk so I jettisoned the Canon stuff from the camera bag and loaded up with mini-Nikon lenses and Olympus Pen toys and headed to Zachary Scott Theatre to photograph the dress rehearsal of a wonderfully funny play called, The God of Carnage.  Shooting plays can be interesting.  When I arrived at the theater the first thing I noticed is that the floor had been painted a deep, bright, fire engine red.  The stage lighting hit the floor and bounced a juicy red light into every actor's face.  Made white balancing a little more interesting...  My biggest concern was whether or not I'd be able to accurately focus my favorite Pen manual focus lenses under the stage lights and you can tell on a couple of frames that I missed by a mile.  I was worried about whether or not the Nikon V1 would focus under these conditions, given that the lenses are slow (aperture-wise) and I wouldn't be able to use the AF assist light.  

I started out shooting at ISO 1600 with both cameras but quickly determined that I'd be able to use ISO 800 under the kind of stage light the lighting designer had cooked up.  While the play was funny and engaging it's still an hour and twenty minute (sometimes heated) conversation between two couples so there are exciting costumes, not many light changes and not much action..... but that worked for me because I was in the "casual" test mode.

I worked mostly with the 30-110 on the Nikon V1, shooting raw, and I worked with the 40mm 1.4 on the EP-2 (which worked well!!!) and the 25mm 2.8 on the EP3.  The wider angle on the EP3 is what screwed up my focusing....  There's just not enough acuity on the screen given the wider angle of view.

I popped the kit lens on the EP3 just to make a comparison with the Nikon in terms of focusing speed and was pleasantly surprise.  It kept up well.

Usually I shoot this kind of work with a couple of Canon cameras like the 5Dmk2 and the 1dmk2N along with some L series zooms.  The 5Dmk2 has about the same level of noise at 6400 as the Nikon V1 does at 1600 as the EP3 and EP2 do at 800 ISO.  The biggest difference is in apparent sharpness.  The big Canon pixels are in their element at these kinds of sensitivity settings.  To be bitingly honest I'd use the EP3 with no real restrictions at ISO 400 and slower.  The Nikon V1 at ISO 800 and slower and, for comparison's sake, the Canon 60D at 1600 and the 5Dmk2 at 3200.  Working at those settings and nailing exposure would get me into the same ballpark, in terms of "noise" image quality, across the board.

And here it's important to say that all of this is predicated on nailing an optimum exposure.  Sure, you can blow out the highlights and you'll have less noise in the shadows but....blown highlights aren't really acceptable.  Alternately, you can pull good stuff out of dark image files if you don't mind a higher noise floor and, by extension, less sharpness in the middle tones.

I found (happily) that the three micro cameras all have the same gameplan when it comes to noise.  It's a monochrome noise that I've described as a uniform sprinkling of black pepper in the shadows and reaching (with less exposure) into the middle tones.  I had the high ISO noise reduction turned off on the Nikon V1 but I understand that the camera still does some noise reduction and it's hardwired to do so.  I set the Oly cameras to the lowest noise setting as well.  And I stayed away from leaning on noise reduction in Lightroom conversions because I wanted you to see the differences between the files instead of differences in processing.

The Olympus cameras have meatier files with more sense of density and mass in the the lower tones and a more color neutral rendition of the higher tones.  The Nikon is less noisy but I'll chalk some of that up to the in-camera noise reduction.  Neither camera is particularly well suited to this particular kind of work but if I had to choose I would give a nod to the Nikon by 5%.  With the right lenses both would be fun.  For this kind of work I'd love the holy trinity of focal lengths to be the 35mm equivalent of 35mm, 60mm and 90mm.  Longer is fun but if the files are clean enough I don't have bad feelings about cropping in.

Next time I head to the theater the Canons and the fast primes go back into the bag.  Focus and ISO performance aside, the increased resolution of the 5D2 gives you a bit more wiggle room for fast action and aggressive crops.

Does all this mean that my love affair with the small cameras is over?  Hardly.  In good light they are more fun to shoot and more fun to carry than my traditional cameras.  And the files are very, very good.  Just put me in the camp that's waiting for Nikon to make good on their prime lens roadmaps.

The images below are a sampling from all three cameras.  The Nikon's are on the top and the EP3's are on the bottom.  While it's not an authorative test it is the way I tend to use cameras under these conditions.  My base exposures were 1/100 with the zooms, nudging up to 1/200 when the light permitted and 1/320 with the fast prime.  The wide angle fell somewhere in between.  But hey, see for yourselves.....

Trying it both ways.

Photographers tend to be an "all or nothing" crew.  When we gear up for a shoot we focus in like lasers on the exact gear we presume will be the best for the job of the moment, then we pack it up and go.  But sometimes the license to experiment comes hand in hand with the job at hand.  I can't tell you why I packed up my Hasselblad 501 CM and the 120mm Makro lens along with my Canon gear on the morning that Amy and I went off to make portraits of scientists for one of our favorite technology companies.  It wasn't logical or rational.  And I can't tell you why I stuck a couple of 120 rolls of Kodak's venerable Tri-X in my pocket either.

We were making portraits of people against white that would become ads and posters.  We shot digital and tethered all morning long and paid close attention to things like white lab coats edged against the white background.  It was great to have some instant proofing.  The firewire connection had no problem matching my shooting speed.  It was a smooth but careful shoot.  The ad agency had no interest in experimenting with film.  But I did.

We had some time between sessions so I asked this scientist if we could take a few quick shots and she agreed.  I extrapolated the Tri-X exposure from the Canon 1DS mk2 ISO 100 exposure.  It should have been two stops different but I went with one and two thirds stops difference because I like a slightly thicker negative and I was certain that Tri-X could handle as much over exposure as I wanted to throw at it without blocking up.

I think my subject enjoyed a little foray into historic imaging technology.  I know I did.  We chatted about it for a few moments while I licked the little band that secures the backing paper around the exposed film, and then we were done.

When my assistant, Amy, and I got back to the studio and finished unloading I got straight to work backing up the digital files, creating web galleries and doing all the back end work we now take for granted.  A few days later I dropped the roll of film by the lab and asked them to "develop and contact."

The next time I was in the neighborhood I pulled into the lab and picked up the film.  A quick glance across the contact sheet and I zeroed in on two frames.  One somber and one smiling.  I scanned the smiling one and made one or two little adjustments.  I compared it with the digital file, painstakingly resolved from a big raw file and worked on meticulously in PhotoShop, and I must plainly say that the digital files rendering of skin tones in digital is not up to par with film technology from the 1960's and 1970's.  You can blame my technique if you want and you can direct me to countless thousands of people on the web who may have mastered black and white in the digital age but all stories are anecdotal unless you live them.

I can dump Canon files in SilverFX and create lots of stuff that's close but it's the tonal range that always seems to give it away for me.  The midrange always seems like gray mush.  I am consistently amazed that, with one or two little tweaks I can get wonderful black and white from the real thing (black and white film)  but the voodoo of manipulating color tones in relation to skin tones in relation to digital files seems so arduous by comparison.  Maybe it's just me.  I can accept that.

After I got this file back I had a husband and wife contact me about photographing them.  They wanted images showing her pregnancy.  I had the studio all set to do a digital session but when they showed up she remarked that she loved the look of square, black and white photographs.  I proofed with the Canon 5Dmk2 but I shot in earnest with the Hasselblad and Fuji Acros 100.  I got the contact sheets back today.  I am still in love with black and white film.  I don't care if it's less convenient.  It just looks better.....

So, for all the people who were getting bored with the writing about the Nikon V1.........viva la difference!

(If you are going to comment about print quality, please keep in mind that the image above is 1600 pixels wide and the original is capable of being cleanly scanned at 16,000 pixels wide. It's also been converted from 16 bits of grayscale to 8 bits of sRGB color. Just mentioning...)


The small camera images from Thanksgiving and beyond. Flash!

Nikon V1 with 10-30mm lens.  A place setting.

Ben.  A mix of daylight and flash from the little, dedicated SBn5 flash, set to fill flash.  Camera in program.  10-30mm.

Ben and I got up early on Thanksgiving morning and ran the 5 mile Turkey Trot race with 21,000 other central Texans.  Ben came in around forty one minutes.  I finished sometime later.  I did not take a camera with me on the run.  As a swimmer (not a runner) I had my hands full concentrating on the race.

The V1 with flash.  In program mode.  with the 10-30mm lens.

There was no shortage of wine or coffee at the VSL Thanksgiving festivities.  All dutifully recorded.

Nikon V1.  Program.  Auto ISO 100-400.  10mm lens.
Belinda and I went out shopping and then for a walk around downtown.  The light was totally different from yesterday's light at the same time.  Amazing.

Nikon V1.  10mm.  Program.

This lens comes alive with a raw conversion in Lightroom.  The lens profile correction is wonderful and the optic spruces up in the corners nicely.  This was shot at 100 ISO.  Go ahead.  Press your nose against the screen and look for grain.

Nikon V1.  10mm.  Program.  Auto ISO 100-800.

We ended up at our preferred halfway point:  Cafe Medici.  Home of the perfect cappuccino.  The weather was exciting.  A big temperature drop and gusty winds.  

Nikon V1.  10mm lens.  At some point I started playing around with Auto Scene Select and discovered that I both liked it, and it gave really good exposures and image files.  

Nikon V1. 10mm.  Auto Super Deluxe Platinum mode with Art overlay engaged.  This is for all the compulsive pixel analysts who like to see the worst case scenario for whatever camera they are about to flame.....

I set this one in ultra-auto and it came back at f2.8, 1/30th of a second, ISO 2800.  YES 2800.  Is there grain/noise?  You bet.  Do I care?  Is it important to me?  You've got to be kidding.

And I don't know what magic robot lives in that camera but the guy on the right is in full tungsten and Belinda is sitting next to a window to the outside and the color is........as close as I'd imagine it could be to right on the money.

One more day of vacation and then we'll break out the boring cameras and get back to work....or will we?



Balance and perspective.

I've been writing a lot lately about the new Nikon V1 camera and it's three popular lenses.  And, of course some will think that this requires me to pledge lifelong loyalty to this system and this brand.  So I thought I'd step back and shoot with a totally different camera today.  I chose the  Canon 1DS mk2 and the manual focus, 35mm Zeiss f2 ZE lens from the Canon drawer.  I got a late start out of the house today because Belinda and I were making some last minute proofing corrections to the LED book which is about to go to the printer. (Yah!!!).  It was 4:30 or so when I left the FedEx office.

I'm such a creature of habit.  I walked the same route I do most weekends.  I like it because this part of town is in constant flux.  The mid point of my out and back route is Medici Cafe which, incidentally, has the best coffee in town.  The beginning and ending point is the Whole Foods headquarters store.  And today I was on a mission to buy a bottle of our favorite Sherry on the way home.

When I shoot with the Nikon V1 I tend to let the camera do a lot of the work.  It's like a squirrel on amphetamines.  Fast to focus.  Fast to review. Fast to go again.  The Canon is different.  I shoot nearly wide open with the 35mm and I try hard to get the focus right.  I also depend more on manual metering with the spot meter.  I think a bit about exposure compensation and I shoot for tonality and range.  Not pop and sharp.

The late November light was beautiful from 4:30 till about 5:30 this afternoon.  Not too contrasty but not flat.  The clouds seemed more resolved and inherently dramatic than usual.  I'd gotten a brief tutorial on B&W in the RAW converter in Lightroom, from Will so I made a few conversions of the files I'd shot just to see what it was all about.  Kudos to Will.  I like the black and white function there.

After weeks of using the Nikon V1 as my primary street shooting camera it felt strange to haul around a camera that weighs five times as much with a lens that weighs at least ten times as much as it's smaller counterpart.  And it took a while to reconfigure my mind to the single focal length lens in an angle of view that seems wide to me.  But after a while I found my cadence and started to enjoy either getting closer or including more.

It's obviously getting darker earlier and the light is so different from the harsh, Summer light.  I was delighted to be outside just when the ambient light started to match interior lighting and I kept walking and looking for interesting stuff to wrap the light around.

After the balance changes and the city lights beat the sky light it's time to head back home.  After a stop for the best cappuccino in Austin.  The secret, I think, is not to fear whole milk.  It adds the perfect taste and consistency to the mix.  If you are going to have a cappuccino made with skim milk you might as well save your money and just drink your coffee black......

This is my favorite image from today's walk because of the sky.  The sun's been down for about 30 minutes here but there's this delicious afterglow that makes it all work for me.  

I'd come to believe that the fabulous VR of the V1 system was the vital component in me getting good, sharp shots from that camera but I found that I'm okay at hand holding some stuff right on down to 1/15th with the big Canon.  And even though it is hardly state of the art at higher ISO's I think it still does a great job right up to ISO 1600.  While preserving good color saturation.

At the end of my walk I ran into a fellow photographer friend, named, Todd.  He's a good photographer and a great teacher.  He was sitting with a friend and during the course of our quick, catch up conversation mentioned my penchant for changing camera systems more often than some people change their underwear (unfair!!!).  I rebutted as follows:  If you had an decent food budget would you eat the same meal at the same restaurant, night after night?  I know I wouldn't.  I'd get tired of even the finest ribeye eventually and want some Chinese food or some pizza.  Hell, maybe even a hamburger....

Same thing with cameras.  Some days I want something light and refreshing.  Other days I want something filling and substantial.  I shot with the V1 yesterday and the 1Ds 2 today.  Yin and Yang.  Foil versus sabre.

The important thing was to get out and taste the light.  Breathe the air.  Move through time and space.  And feel the flow of late afternoon.  The camera was just a motivator.
