Some people said the Elmar M65mm f/3.5 can also be used but this lens is very difficult to find now. The idea is very simple - unscrew the lens unit from its original focusing tube and attach it to a new focusing tube which is suitably modified to the correct length and having, of course, a Mamiya mount for attaching it to the camera body. If you want to use the lens again on the M body, simply re-fit the lens unit to its original tube again. Here in Hong Kong, I have it done by my friend who is an expert in converting these equipment. My Elmar 135 is attached to a Tamron 135mm focusing tube, converted with a screw mount in front for attaching the lens unit and a bayonet mount at the rear for fitting to the Mamiya body. The beautiful thing of it is that I can still use the automatic exposure of the camera (fitted with an AE finder). The slight inconvenience is that I have to stop down to the desired aperture for the exposure measurement. I spent about HK$6000 for the lens and the conversion tube. I consider it extremely worthy of the money spent because the original Mamiya A150mm f/2.8 costs up to HK$9000 and the quality - you can imagine which is the winner. I'll talk to you about the conversion of the 200mm later. Regards, TK Chan tkc@hkstar.com >TK, > >You're not joking.......you really have had M lenses adapted to a Mamiya >645? By whom?
