Originally posted by susanc I recently picked one of these up on eBay for a great price. It hasn't arrived yet but I'll need to expand my manual focus lens collection to take full advantage of it.
As I understand it, there are certain lenses which can't be used with it due to their physical construction. Does anyone know where I can find information about which lenses to steer clear of?
I don't know about specific exclusions that some members have posted, specifically with respect to short lenses (but you may need to check the possibility for interference between lens back element and the movable elements of the adaptor.
I bought mine new to use with my PZ-1 in 1991, and the manuals even then said if can only be used with F/2.8 and faster lenses.
Fortunately neither the adaptor or cameras seem to be able to read the manuals.
I have found it works properly in all lighting conditions up to F/4.0 lenses.
My experience to date is as follows:
SMC-Pentax 300mm f/4.0
SMC-Pentax 50 mm f/1.4
SMC-M-Pentax 100mm f/4.0 macro
Vivitar Series 1 70-210mm f/3.5 (Version 1 of lens)
It works with all these just fine.
It DOES NOT work, however, with my Vivitar 400mm f/5.6. although I did not expect it to.
I have heard some people claim it works with the Pentax 300mm f/4.5 KA mount, but you would need to check.
All the above lenses work with the adaptor on my PZ-1, *istD, and K10D, You will also find a recient thread on the 300mmf/4.0 where I have posted a photo taken using the 300mm and the adaptor
