YS adaptors

<p>Out of curiousity is there any retailer who stocks YS adaptors for various cameras? I don't really have a pressing need for one at the moment, but I am hoping to get a Spiratone 85mm f/1.7 lens down the road and that has a YS system mount, and I would like the ability to get any good condition lens and get the adaptor (for OM) seperately if I need to. Thanks.</p>

<p>i have some ys lenses  / including an 85mm<br>

the ys system is compatible with the T and T2 system except you lose the auto diaphragm.<br>

the canon FT apparently is ok but the canon FD is kludgy. I bought a long zoom for my miranda and it came with a canion mount, there is an additional bracket which must be removed.<br>

Rick Oleson says that the fixed prong on the FD adapter  must be adjusted for max lens opening., and then the adapter is commited to lenses with that max aperture.<br>

newer mounts are simply not available. the only fairly modern cameras that have the mounts are Nikon na Minolta. Not until I wil the lottery will I ever get a YS for K mount. Custom machining.<br>

WWW.BUTKUS.ORG    has a YS manual.   http://www.butkus.org/chinon/y-s_mount/ys.htm<br>

when I got my Miranda 85mm, I had to return it as the  miranda sensorex has no stop-down button.  so these lenses come both ways. they exchanges it for the one with the lever.</p>

<p>The 18mm f/3.5 and the 135mm f/1.8 also show up on the big auction site,.<br>

there lenses are "old school"  with heavy construction.<br>

be willing to buy a lens and mount just to get the lens.<br>

Not a Pentax K or a canon eos.<br>

the kalimar auto t was totally different.<br>

I read somewhere that some later Sigma lenses sold as fixed mont were really YS lenses, perhaps with</p>

<p>other makers such as sun, rokunar? cambron? and sigma sold YS mount lenses.</p>
