A tale of three lenses. Two Panasonic and One Olympus. In the end it's all about the optics.

 25mm Panasonic Leica.


I thought it might be fun to post some samples of the three lenses I was carrying around yesterday in San Antonio. I'm practicing with the lenses and camera because I have several jobs coming up at the end of the week that will require me to shoot lots of images in all kinds of lighting and I'm planning on taking the two GH3's, some cool modern lenses and a few old chunks of glass and I'd like to proficient operating the cameras and quickly getting in to the groove with the different lenses. There always seems to be a re-adjustment period required for my brain when I switch between sensor sizes and especially between formats.

The image just above and the one just below were taken with the Panasonic/Leica 25mm 1.4 lens. It's crispy and modern looking and it looks good from wide open all the way down to f8. I'll use this one for all the social photography I plan on doing this Saturday. This is one of the lenses I originally bought when I was shooting with all the earlier Olympus gear. It works well on the Panasonic but my one wish is that it had image stabilization....(or that the GH3 had IS built in). I know the Olympus cameras have great IS built into the camera but we'll see how abstaining from coffee and stress work out before I go out and buy yet another solution.

The six images just below were taken with a very inexpensive zoom lens from Panasonic. It's the 45-150mm lens. It's relatively tiny, has image stabilization and seems to perform well enough...especially for the price. It's a bit slow for interior work but for anything exterior it should work well. All of the photographs in this blog were done handheld which should be a caution sign for anyone hell bent on using the images as the final litmus test of quality. We can always do better with a tripod... 








The final six images (below) were all done with the ancient Olympus Pen FT half frame 50-90mm f3.5 zoom lens from the early 1970's. It's not as contrasty as the modern lenses but with a little boost in contrast and just a tiny, tiny smidgeon of sharpening I think it holds up well. The secret with older, single coated lenses is to try never to shoot them into a light source unless flare is the special effect you are looking for. The lens is all metal construction, incredibly well made and in perfect operating condition decades after being first pressed into service. I find its incredibly smooth zoom and focus rings to be as good as anything on the market in the last few decades.







Have I learned anything wildly new shooting the GH3, it lenses and the old legacy lenses?

Yes and no.

The new glass is sharp and good pretty much across the board.

The older fast lenses from the Olympus Half Frame Pen FT series are 

remarkably good. As good (one stop down) as just about anything being cranked out

by the camera makers today.

The 60mm f1.5 is awesome at f2

The 70mm f2 is really sharp and nice at f2.8 

and the 40mm f1.4 maybe the sharpest lens I've used for this camera system.

They are a bit more trouble to use than the AF stuff but the reward is

in a look that's a pleasing combination of 

sharp and mellow.

That's about it.

No big fanfare, just two interesting Olympus OMD e-m1 posts from my friend at ATMTX

The views expressed at ATMTX's blog represent his feelings about the cameras being reviewed and don't necessarily exactly reflect my views here at VSL.  Head on over to his site and read what he has to say about his long term, hands on experiences with two of the hot cameras of the day. Oh...yeah, he directly compares the e-m1 with Canon's 6D, which he also owns....

Interesting assessments!

Thanks.

Another chance for an ancient lens.


I went to San Antonio yesterday to visit my parents and to walk around and try a few different lenses with the Panasonic GH3. My parents are doing quite well. And San Antonio is as fun and colorful as ever.

I took along three lenses: the 25mm f1.4 PanaLeica, the el cheap 45-150mm f3.5 to 5.6 zoom and an absolutely ancient Olympus Pen FT (manual half frame ) 50 to 90 mm, constant f3.5 zoom lens. I'm pretty sure that the old Olympus lens isn't even multi-coated but I thought I'd give it a try since I have two copies of the lens and the zoom and focus actions are still incredibly smooth and the aperture ring turns with a wonderfully damped precision.

I spent a lot of the day with the 25mm on the front of the camera because it approximates so well the angle of view I learned to like from shooting successive generations of 50mm lenses on old 35mm film cameras. I switched to the new Panasonic zoom when I got to the market because it was easier to pick out details and faces. Near the end of my time downtown I switched to the old Olympus zoom.

Because of the primitive coatings I expected the lens to have more flare and less contrast. Because of the zoom's advanced age I expected that the optics would never be able to match the glorious results of nearly forty five years of advanced optical progress. So I was prepared to open the files in Aperture, review them and then move on to the little gems created by the other two, thoroughly modern, lenses.

This was the first file I opened at full screen and I was partially correct, the image did need a bump in contrast. I chose to make the correction in the mid-range with the controls in the Aperture shadow/highlight menu. But I was partially incorrect because the file needed very little sharpening. No more so than a typical digital file from a camera with an filter over the sensor...

The Olympus zoom is a great series of focal lengths for a portrait photographer and, with the one button ability to zoom in to 8x and gauge correct focus it's a pretty handy combo with the Panasonic GH3. I'm looking forward to shooting some portraits in the studio with more controlled lighting. I already like what the lens optics are doing for the background at f5.6. Let's see what it looks like when paired up with a beautiful face.....

The first good shake out walk with the Panasonic GH3.


If you read the VSL blog regularly you'll know two things. I recently bought a Panasonic GH3 for video projects (yes, I tested it head to head with a Canon 5D3 and prefer the usability of the EVF and the smooth, luscious detail of the files from the GH3) and that I have no allegiance to any one camera system. Whatever works, works.

I bought the GH3 before I headed to NYC and barely shot five frames around the studio. When I got back home I spent an evening reading the manual and going over the menus ( which are straightforward and make sense).  I finished all the work I needed to get done today around 4 pm and decided to take the GH3 out for a walk, just to see how it felt and how it performed.

To date I have three lenses for this camera: the older kit lens, the Leica/Panasonic 25mm 1.4, and the 45-150mm 3.5 to 5.6. I have a new version of the kit lens heading my way and the offer of lens loans for most of the Panasonic premium line from Frank. I also have a nearly complete collection of Olympus (film) Pen lenses from pedestrian to esoteric high speeders. Today I made things simple and I just put the old kit lens on and set it at aperture priority and f5.6.


It's kind of silly and useless to test a camera in perfect daylight and with the lens stopped down to its optimum aperture. But I learned what I needed to about the camera and its operation during the course of my walk. The body is just right. Not too big but not so small that the buttons are smushed together. And speaking of buttons....there's pretty much a dedicated button for whatever you want to control. A far leap from my previous, screen centric week. 


 While I am spoiled by the full frame, huge resolution files from the two Sony cameras (a99 and a850) I find the images from the GH3 snappy, saturated and very sharp. The dynamic range seems ample and the metering is right on the money.


The real litmus test for me will be the rendering of skin tones. The tests I've done in video lead me to believe that things will be great in that department but you never really know until you try it and test it for yourself. I like the camera well enough that I'm buying a second body tomorrow and pressing it into service almost immediately for several video projects for clients. The second body is nothing extraordinary. A professional should always travel with a back-up to his or her main camera and one that uses the same batteries and menus is a distinct plus.  

If the camera serves me well I'll flesh out the lens selection with the two Panasonic 2.8 zooms. In the meantime I'll be using the Olympus Pen legacy lenses, Sony Alpha lenses with an adapter and the handful of Panasonic lenses I've already gotten. The worry is "lens creep." That's like mission creep. It's when you progressively justify and rationalize more and more lens purchases until you are knee deep in a system that you bought just for a specific function.

For those few readers who've come recently from forums and are hard of comprehension: My use of the Panaonic GH3s doesn't mean I'm getting rid of the full frame Sonys, nor is it a blanket endorsement of the Panasonic cameras. It just means that I like them better for video and I'm keeping an open mind about their efficacy for still imaging. If you don't like that; if that's not binary enough then you should read something else instead.


In terms of issues I am seeing two things: The contrast of the files could be a little higher and there is a tendency for the files to go slightly magenta. In the camera's defense, I have profiles down to a science for the Sony cameras. It will take a bit of time to get up to speed with the Panasonics. 
Finally, I will have to learn how to walk around with less weight on my shoulders. I hope it's enough weight to defy the centrifugal energy of earth's spin and keep me from flying off into the ether....







Three little systems. The Sony Alphas. The Pentax K-01 toy cameras. The Panasonic GH3's. Seems about right as we're nearing the end of 2013...

Yes. Here's the loupe I wrote about yesterday...


It works well. Works on any number of cameras and, if I was trying to do video on a DSLR I'd have one in a hot minute. Wait, I already do have one. It's bolted to my Pentax....so I can shoot some video... Found out that the base of the connector plate is compatible with some Arca Swiss quick release plates. Who knew? You can get it at Amazon for about $120.

Here's the link: Great, Cheap Loupe.

Have fun seeing your LCD better.

A light, airy and silly post about an absurd purchase from last week....

Subtitled: Crazy stuff photographers buy at trade shows. Not the camera.....

If you read the blog you already know that I have a soft spot for silly cameras that are secretly great image makers but you might not know that I, like many other technical leaning male picture makers, have a penchant for buttons, knobs and anything else you can add to a device that makes it look cooler or more.....meaningfully complex. It goes back to that whole painful mastery thing we talked about on Sunday...

At any rate Nick Kelsh and I were tooling around the trade show in New York looking at all the cool new video stuff when I can across a small table whose inhabitants specialized in "viewer technology."
They had all kinds of viewfinders and hoods and shades for the LCD screens that hang there on the backs of still and video cameras. I found the biggest, meanest, gnarly-est one I could and measure it with my pocket laser rangefinder/caliper system to make sure it would fit on the backs of my Samsung NX 300 and my remarkably cool Pentax K-01's and then I borrowed a hundred bucks from Nick and bought one.  It actually occupies more cubic space than either my Pentax or my spunky little Samsung. And it's photographic comedy to see it in use....but now I can get my money's worth out of those expensive little flat panels that keep showing up on the backs of otherwise perfectly good cameras. 

The company that sells this is called, Swivi and I think the product is a bargain at $100. It's got an eyepiece blind (for what? I'm not sure...) and a big diopter adjustment ring that's made out of metal. You can see that the rubber eyecup is steroid enhanced. Absolutely hulking.  You'll think you've gone back to the eyecup on your Arriflex 16S. 

The loupe construction is hinged so you can flip up the magnifying element and look at the shaded LCD directly or hold the camera at arm's length in classic, stinky baby diaper--daddy needs glasses" style. Wonderful for new school or old school. 

Best of all this beast bolts onto the bottom with belligerent bravado. The all metal mounting hardware is a salad of metal bolts and rods that allows the unit to be custom fit to just about any camera with a tripod socket. Shifting left and right or up and down is easy and when you've got it where you want it the whole thing locks down tightly. And wearing it with a diminutive camera will make you look like the biggest photo nerd in the area. But I'll still bring it around with me when I actually want, or need, to see what's on the screen at midday in the blazing sun. YMMV.



The wonderful thing bout the construction of the loupe and the mounting hardware is that
nothing occludes the Marc Newsome signature on the bottom of my camera. 
And secondarily, nothing gets in the way of the battery compartment.

The one fly in the ointment? You lose your tripod socket.
C'est la vie. That's what vise grips are for......
