Xenotar 135/3.5 on SL66

I dug my dehumidifier yesterday for my spared #2 shutter, and I found one long forgot Xenotar 135/3.5 sat there stared at me, I bought it last years, and then quickly shift my interest into big brother 150/2.8, this one left in the box till now.

It came as a barrel lens, with iris only, but I managed to fit it with a proper #1 shutter, and so there it can be mounted on Byron, or on my SL66.

This lens did not need extension tube, you can see bellows extends just about 1.5inch and you got infinity already, if you extend bellows to the end, focus can be as near as 1.5 feet.

Next time I will try to mount this beauty onto Byron, 135mm is quite wide for 4x5 snaps.
