Focal Lengths to look For.. (Tmount)

[kb244]

So after all the dispair of tryign to find a M42, CFD, NI, etc lens adapter for the Pen-F for less than 100$ without avail I decided to take a different approach based on information from one of my co-workers.

I was checking one of the lens on the store shelf, a Super-Lentar 35mm f/3.5 , that looked like it was a pentax screwmount lens, but placing it on one of the pentax bodies would not thread all the way and the back of the lens was far too recessed to have worked. So then I remembered if it won't thread all the way, it's usually a T-mount thread. Sure enough the Lentar was a T-mount lens and I was told that in the past there were quite a few third party tmount or T2 lens as universal lens and such.

Well I remember seeing on B&H a used Bowen Pen-F to Slide duplicator adapter. Well all the Bowens uses the T-mount thread so you would just use any Tmount adapter for a camer to make it work. Well this adapter was 14$ so I figure sure why the hell not, theres least 5 or 6 non-telescope lens here in the store that are t-mount and I'm sure I can find some very cheap ass normal focal range lens on ebay for dirt cheap such as these lentars and other lens.

But I'm curious. Anyone know of any third party that made these lens in wider than 28mm, or in longer ranges faster than f/3.5? (like an 85mm f/2 maybe)

Well depending on how soon B&H ships the adapter I should be able to play with the lens shortly enough. Sure it might not be a FD, Nikon, M42, etc common adapter but least I have some options if this works.

Though I wonder, I know there existed FD->T adapters for Canon lens I have one at home, but the concern of course that the adapter for the lens itself is not corrected for infinity and I'd basically be using most my FD mount lens for macro-ing.

However If I could find a T mount for my Tamron Adaptall lens (I already got FD, Ni, MD, M42, etc mounts for my tamron lens) then I could use my adaptall lens including my 90mm f/2.8 1:1 Tamron SP lens on the Pen without worry of correction.
