Tair 11A 135mm f2.8
I read about this unique lens with some remarkable characteristics: made in the former USSR; known as a “bokeh monster”; small for a 135mm f2.8 (though still relatively heavy). It’s a novelty lens popular with photo enthusiasts and collectors. Intrigued, I checked it out on ebay and found a good quality copy for a good low price. So I bought it, and I bought an adaptor to marry the m42 screw mount to my Sony A7R cameras. From the serial number I understand it was made in 1988.
I have taken it down off the shelf several times for the fun of it. I would do it more often but the lens is clumsy and not so easy to use. It is manual focus only and the aperture adjustment is complicated by a limiter that has to be adjusted to move freely about the settings. There is no electronic transfer of information from the lens to the camera. I got use to these characteristics in time, and had some pleasant experiences testing out the capabilities and enjoying its features.
