Do you photograph with a mirrorless camera? If yes, you might want to find a good, film era, 135mm lens and an adapter. They seem to have, miraculously, gotten much better than I remember them having been.


The one feature that mirrorless cameras ushered in and which I embraced from the outset is the ability to magnify the preview image in the finder/LCD so that we can manually focus more accurately. We seem to think that lenses only just became really good in the age of digital cameras and digital sensors but, more and more, I'm finding that older "legacy" lenses could already be very good on their own; even if some of the optical design considerations were different for film than for digital.

I started buying mirrorless cameras when Olympus came out with the EP-2 which offered an EVF attachment that allowed eye level focusing and composing. The camera was among the first with a shorter lens flange to sensor distance which allowed one to use dozens of adapters to retrofit hundreds or thousands of lenses to the body. I bought my first mirrorless camera specifically to use with my collection of Olympus Pen-FT half frame lenses; many of which are still quite good performers. 

The Panasonic S1 series works very well with older, manual focus lenses that were originally designed to be used on film cameras. If I find an interesting older lens that was designed for use on an SLR I go to Amazon and check to see if there is an adapter available for that lens mount family which will work on an L-mount camera. Usually the adapters are available in the $20-$50 range and it's rare for me to get one that doesn't work well with both the camera and lens. I've gotten one or two really cheap ones with too much play but most are well made and almost every one I've gotten has allowed for infinity focus.

I recently picked up two Contax Y/C Carl Zeiss lenses at bargain basement prices. These were both lenses designed to be used on the mid-1980s Contax line of SLRs. The lenses and cameras were built in Japan by Kyocera but before you turn your nose up remember that Kyocera was the maker of several well received Leica SLR zoom lenses, and that the engineers at Carl Zeiss designed their branded Contax lenses and set the parameters for their manufacturing and quality control. In short, with a few exceptions, most of the Contax lenses from that time period, if well maintained, are good-to-excellent and, perhaps a step above other brands from the time period. 

I owned a number of Contax lenses back in the late 1980s when I shot with an RTS II, and then an RTS III camera, and never had reason to complain about their optical performance. 

When I found a little collection of the lenses in the used department of a camera store I opted to buy the 28mm f2.8 (which I wrote a bit about yesterday) along with the 135mm f2.8. Both are later, MM mount lenses with slightly improved coatings and no "Ninja Star" aperture artifacts. You can tell which lenses are the later models because their smallest aperture settings/numbers on the external aperture rings are colored green. 

There was a 50mm on offer as well but I skipped that because I already have a good copy here in the studio which I had originally bought to use with an earlier Sony A7 variant. In retrospect I might as well have bought the one at the store since the supply is ever dwindling, but I'm trying to curb my reckless avarice for lenses. 

I found an adapter supplier I like for two reasons. First is that every adapter I've bought from them has fit both camera and lens snuggly and allowed focus to infinity and, second, they are priced at under $20 apiece. I have two of the adapters and use them on the two Contax lenses I use most, switching out when I need access to the third lens.

When I shot with 135mm lenses in the film days we did not have image stabilization or really good focusing assistance from our cameras. Sure, the optical finders were optimized for manual focus lenses, and there were split-image or microprism focusing aids but all focusing was done strictly at whatever the viewfinder's fixed magnification was. Now we can "punch in" 16 time or even 20 times on most higher end digital cameras which means we're focusing at multiple times the accuracy that was available on something like a Nikon F3. 

While I did an acceptable job focusing a 135mm lens on a traditional camera I can plainly see the huge advantages of magnifying the viewing image in order to fine focus. And that brings into clear view the advantages of focusing while the images are being stabilized.

We tend to think of image stabilization as a benefit only at the time of exposure. We push the shutter button and the image is stabilized for the duration of the exposure. But if you think about it from a different point of view; that of IBIS being a focusing aid, you'll see that stabilizing the overall view of the image while manually focusing also allows for much more precision and accuracy in the process. Which means a much higher number of better focused keeper images. 

All of a sudden, and maybe for the first time, we can actually see and take advantage of the innate qualities of some of the lenses we previously dismissed as "good in their time, but...." 

When I looked at the results of my casual test shots with the older 135mm I was happily surprised that, like the 28mm lens, the 35 or 40 year old lens was entirely capable of matching current AF lenses in that focal length range, without issue. An interesting observation for someone like myself who is happily disposed to experimenting with old lens-to-new camera adaptation.

Out enjoying an early spot of Summer weather while savoring the odd magic of a 28mm lens. And an ancient camera body.


For some reason I'm lately captivated with getting wider. Well, not me personally but my appreciation for wider angle lenses than the normal focal length (50mm)  and longer lenses that have always been a more comfortable part of my routine. The 28mm f2.8 Carl Zeiss Y/C lens in particular has me working to better understand composition with that angle of view. I've come to like these older, film era lenses for several reasons. First, they didn't have in-camera distortion correction when this lens was made back in the 1980s so Zeiss had to make it as geometrically correct as possible. Now, that doesn't mean it's necessarily sharper in the corners but it does mean that there is no interpolation black magic happening which sometimes ends up looking as through an image has been unnaturally stretched. The interpolations to correct for inherent lens distortions also means that the stretched corners have made up pixels which can sometimes be...unconvincing. It doesn't need "fake" corrections since it's already well corrected. 

I used the lens with an inexpensive C/y to L-mount adapter which allowed me to put it on a Lumix S1 for today's casual photography. After an hour or so I was reminded that although the S1 is not the most expensive or extravagantly spec'd of the three four Lumix S1 series cameras it is, nonetheless a very good image making machine and using it just a day after spending time with a Leica SL2 I was surprised how close the performance, viewfinder image, and file integrity is. In fact, it's a highly competitive camera body for the L-mount systems. I'm beginning to wonder just how well it might perform with the Leica 35mm f2.0 SL lens might work with it. If I find some more change in between the couch cushions I may just find out...

But camera bodies aside, I am surprised and impressed by how good this particular lens, which was used and purchased for little more than a song, is when it comes to rendering highly defined detail and rich colors. I imagined that newer lenses would be leaps and bounds better but I'm constantly revising my opinions about optical progress. I'm almost ready to believe that many earlier lenses were designed and built to very high standards but that cameras of their time didn't allow photographers to fine focus reliably and accurately the way current cameras with 5.7 megapixel EVFs can when used with 16X image magnification when manual focusing. I noticed the same uncanny improvement when it came to shooting with the 135mm f2.8 Carl Zeiss lens from the same period. My memory of the lens when used in the film days was that it was good but not "great." Now it seems much, much better. But I guess I'm not taking into consideration that I'm comparing relatively low res Tri-X film performance, sans image stabilization, with super accurate focusing, much higher imaging resolution, total control over contrast and quite good image stabilization. Those factors elevate nearly every lens. At least I think so. 

The beauty of photographing with a good, manual focusing 28mm lens is that one can operate in either of two modes. You can use a smaller aperture, like f8.0, and zone focus when you are out shooting scenes that require deeper focus and quick reflexes, or you can take a bit more time to use your EVF, punch in on the point you'd like to target for the plane of sharpest focus, and then shoot. Either way you'll be able to get lots of stuff sharply focused and I'm thinking that a well focused image makes every lens look like it's been improved. 

I like having a smart watch. I got the newest generation Apple Watch for my birthday last October. I used it for many things today but the most fun was using it to measure the distance of two different walks today. The first was up and down the hills in our neighborhood. I walked with Belinda and we did a leisurely 2.5 miles with about 800 feet of changing elevation. I walked this afternoon with the camera and logged in about 3.75 miles. Mostly on flat, urban terrain. It's nice to quantify a walk and see just how much movement you are getting. No wonder the soles of my Merril hiking shoes are wearing down through all the tread... I guess I knew they would not last forever.

I am always amazed at this "green space" at the Seaholm development. 
People love to bring their kids here to play on the green Astroturf. 
There's no mud to worry about and the kiddos live the flat uniformity of
the space. But dog owners and their dogs also love the space
and the cute little pooches love to relieve themselves on the fake grass.
While I'm sure the whole surface gets power washed each morning...
I'm not sure I would feel comfortable laying out on the 
ground cover to work on my tan. Just conjecture...








 After all the excitement of getting the Leica SL2 it was a comfort to walk around with a more familiar camera and a vintage lens. There is a familiarity that makes the camera seem so well sorted and well integrated into a walk. It's like strolling with a friend. 

It was a balmy 72° this afternoon and blue sky everywhere. I cleaned both bathrooms this morning and felt like I really deserved some quality time with my camera and lens. I am amazed at how nice a day it was. 

We're going to get cold later in the week but we like to "make hay when the sun shines." Or photographs.

So far, on a personal level, the year is off to a good start. No big drama and no big changes. And that's good since I fear change. Everyone does. Don't write a comment about how you never fear change. We'll have you well pegged as either delusional or a liar.
