Canon 85mm f/1.8

I want to know if a fast lens of longer focal length like the Canon 85mm F/1.8

is difficult to focus accurately on a shorter base length rangefinder like the

Bessa R2a I own? What is the longest/fastest lens you would consider using on

a rangefinder of this base length (I believe it is .52?) Thank you!

Using a 90/2 on one I would say only that you need to be extra careful. It can work. The

R3A / R3M would be better.

Get an eyepiece magnifier from places like megaperls. Nikon's magnifier for the FM/FE series will also work.

Well that's like asking " Is it hard to play the clarinet pretty good?" The answer is " It

depends." Same with pictures. I have that same lens as well as the Canon 100/2. If you are

going to shoot portraits with it and you have it on a tripod you're going to get a lot of pics in

focus. If you are trying to shoot sports you're going to have a lot out of focus. As you use it

you'll get better. The real question is if you will like the image it records. In my experience

it's pretty average. I like the ELMAR-C 90/4 better by quite a bit. Like to know what you are

going to use it for, that would help. But if you want to use that lens on that camera - hey go

for it!
