Not a nightmare but a pleasure and a privilege. I've been blessed with good friends and a very understanding wife. I get the fun of being able to choose which group of lens to take now...Many years ago I had to make do with only two...Back then I felt rich as I had a K1000 with a 50 f/2 and a Sears 135mm lens.

I do find the manual focus on my model very critical, it has to be set very precisely to get sharp pictures, I know my aging eyes factor into this problem, but I do feel that any softness in results could be down to the above, with the Makinon shots are very sharp, when you get it right. Just my thoughts. ... Jack
Thank you Jack. I've seen many photos taken with Cat lens that were sharp and contrasty....then you see the posts from some who can't seem to get a sharp photo with theirs. I've wondered if it was the lens or the photographer. I'll soon see I guess.

AFAIK, it's the only Autofocus Reflex lens ever made (only the branding changed after Sony bought Minolta).

Here's an article about it:

P.S.

NHL has one that he uses with a Sony A900. See this thread:

Some sharp photos with that lens.

Hi Dawg,

When I was in college, there was a camera store around the corner from my mom's place, and I remember walking by and leaving a drool trail from the Vivitar S1 Solid Cat they had displayed in the window. . . Never got one though, but obviously the long tele bug has been persistent. . .

I have the Tamron SP 500/8, and that has satisfied my Cat requirements. . . don't use it much, but I do grab it once in a while when I want to have something long in a relatively lightweight kit. It's just out of working range with the F 1.7x AFA and the K-7, but the extra sensitivity of the SAFOX IX AF sensor might just give me a really lightweight AF 850/13.6 Cat in good light. . .Keeping my fingers crossed.

BTW, penolta has one of those Minolta AF Cats IIRC. . .

Scott...I left a similar drool trail from the drugstore home after looking at the photo mags back then...I couldn't afford the magazine so the lens was way out of the question. Now i get to indulge myself for a change.
