. I just got too excited at the prospect of finding a way to use some lenses of the quality I craved!
But - that error aside, in terms of the mechanics though, I'm not going to have to start shaving metal pins or putting bits of filler metal into weird places or leaving the thing only half screwed on to use them (clearly though do your homework first, ie some m42 lenses seem to clash with the mirror)?
Many thanks Mike
With the Pentax adapter, you should be 100% safe in regards to mount compatibility. As for the lens mirror issue reported on another recent thread...that kind of thing is extremely rare and is the result of Yashica having developed a line of lenses (DX) for a particular body series that were not even compatible with other Yashica bodies. Go figure...
The only general issues regarding M42 lenses are:
- Proper adapter
- Ability to have fully manual aperture
The first point, you are aware of. The last is not well appreciated until you get a lens that will not stop down for metering or exposure. The key to the second point is to only buy lenses that lack the auto-aperture pin or have the "auto/manual" switch. Almost all M42 lenses will pass this rule. The most obvious exceptions are certain Russian lenses of recent manufacture that have the auto-aperture pin, but lack any way to use the lens in manual aperture mode (e.g. MC Zenitar 16/2.8, Helios 44M-4, and others in M42/Zenit mount).
