Hello:
135mm is a bargain if you also use an accessory brightline finder - otherwise, the view is minuscule. SHOOC if you can find one.

I liked the lens, though not my favorite, I was kind of chimping and guessing with the frames, but I just got the SHOOC, NIB, what a nice finder, and terrific size, so I guess I will have to try again. ;-)
I also have the same focal length for the Nikon S2, but it came with a generic finder, the varifocal finders remind me of looking the wrong way through binoculars, well, maybe I am looking the wrong way. ;-) I was going to give up until I just tried the lens and it was not quite as rifle sight tight as it had seemed. I did just get the SHOOC in the mail today, it is quite a difference.
I also somehow ended up with some spares, as they came in the box with something I wanted more.
The Hektors seem to optically perform well, but I have naught to compare it with, except the Nikon. I understand they are not difficult to service as well.
At the reasonable prices, you are not going to get hurt in the crossfire to give it a shot, and there are times when the 90 is falling short.
Regards, John
