Originally posted by RioRico Nice batch, Lowell. But you're missing some Takumars: 105/2.8, 135/2.5, and maybe the little TeleTak 200/5.6. You still don't have the Vemar-Sigma 12/8, nor anything at 19-20-21mm. You might also look for the Enna Tele-Ennalyt 240/4.5. Your quest is not complete.
I deliberately avoided taks on the M42 kit. I have SMC (K) 105/2.8 and 135/2.5 lenses already, so i felt these were too clsoe to the S-M-C taks to repeat those lenses.
In fact I like the 105 and 135 presets I have in the kit. My M42 kit was meant to be a little different, and the presets make it that. As for the 200/5.6 you will note that it fails my criteria, of being a focal length I don't have or faster than what I have.
As I said, if I trip over something I might still get it, but I am no longer prowling for lenses. I am thinking for the 17-21mm rectalinear range, since I still have an old rikenon 135/2.8 that simply sucks, (no other way to put it) it will be a mount doner if I can find a nikon or minolta mount lens
really cheap
p.s. the rikenon is so bad I don't count it in my collection. it simply occupies a spot in my lens case where the 16mm will now go
