Forums > Back > Lenses with a small front element
#1
What lenses exist in EF/FD/M42 mount with a thread diameter down towards 37mm?



I have this 8x tele-extender with 37mm inner thread that I got surprisingly good result with on my old compact, and I would like to play around with it some more. I recently got FD and M42 adapters, so I have a plethora of possibilities. I figure there's no theoretical limit to how small a front element can be, but how small front threads have been manufactured in practice?



There might also be some that have a larger thread than is really necessary, and so would be more useful for this purpose. Any particular lenses of this kind I should know of?



Yes, I know I'll have manual focus and small aperture and vignetting and defects and stuff, but I'd like to toy a little more with it.



Thanks,

-Lars
