There are many excellent M42 screw mount lenses (in addition to many of the SMC Taks). You really should visit http://medfmt.8k.com/third/cult.html Some of my favourites are:
Tokina SL RMC 17 3.5 Carl Zeiss Jena MC Flektogon DDR 35 2.4 Vivitar Series 1 VMC [Komine] 135 2.3 Vivitar Close Focusing [Komine] 135 2.8 Vivitar Series 1 VMC [Komine] 200 3 Vivitar Series 1 VF VMC [Kino] 35-85 2.8 Of these, I like the CZJ 35/2.4 and Vs1 200/3 the best. P.S. don't forget Tamron Adaptall, especially Tamron SP (the SP 300/5.6 is marvellous) Jim www.jcolwell.ca
