The focusing mechanism is interesting. It has a quick focusing ring, and 
a second, fine focusing ring that gets it into the macro mode, 
although I think it is actually around about 1:2. The feel of the 
focusing is pleasant.
   



Do you happen to have a photo of the lens, Derby?  (Thanks.)

Hi Fred,

This is the ebay listing...

I have to say, I'm a bit intrigued with this lens. It is definitely 
krappy, but in a funny lomo sort of way. Might see what artyfarty uses 
it can be put to.

Thanks, Derby.  That's interesting looking.  I've never seen one of 'em
before, and I was just curious.

Yeah.  I picked up a Tamron (Adaptall 2) 70-150/2.8 zoom with an extra
control ring on it, for controlling its soft focus effects (from no
softening to a moderate blur and everything in between).  It is not a
krappy lens by any means, but I pick it up, not because it might be
super-duper-sharp, but because I was interested in playing around with
the soft-focus effects (as a portrait lens).  Sometimes you stumble onto
some odd personality older lens that just hints at fun so much that you

Hi,

The YS-mount to begin with was used in the 70's by a number of lens 
manufacturers (maybe they were al Sigma?). Sun, Focal, Sigma. Its also 
called the T3 mount.  This mount was developed by Sigma. Some reading 
can be found at moghans website about medium format 
http://medfmt.8k.com. In 200 mm thre were three vieities. First your 
f3.5. The the f4 - focus down to 1/3 in macro mode. Its quite an OK lens 
when not used in macro - otherwise its a real softfocus. The last is the 
f2.8 which is a decent lens.


If you want the lens to be sharp. Don't use the fine focusing ring which 
is really the macro ring. It extends the front elements from the rest of 
optics getting you closer to the subject.


The XQ was a series of lenses from wide angle to 400 mm. The 200mm and 
135mm are quite common. The 200mm f2.8 and 300mm and 400mm lenses show 
only up occasionally.


I have a 200mm f2.8 for sale right now by the way.

Cheers,

Ronald

Its a pretty soft lens to begin with, but in macro, it goes sooper 
soft focus.

I picked it up for about $40 so I can't complain. But it certainly is 
has an odd personality.

The YS mount was a Sigma exclusive.  It is not the same as T3.
