I have but one manual focus lens, a Vivitar 70-210 f/4.5 (the one with the flange that's too big). I've only had it about two weeks, and I've played with it a little, but this evening was my first real opportunity to use it at the first T-ball practice of the year. I figured I could hone my skills while the kids worked on theirs.
Anyhow, if I didn't know any better, I'd say I had a back-focusing MF lens. It seems as though to get a sharp picture, I have to focus a tad in
front of my subject. I popped on the kit lens and it seemed to be the same.
Now, I seem to recall a link someone posted (though it may have been on that other forum) that showed pictures of a sewing needle in and out of focus, but I can't find it now. I think it was talking about a discrepancy between what's in focus in the viewfinder versus the photo. Is this what I'm experiencing? Everybody else see the same thing?
Just to calm myself, I did my first D70 focus test, and with the FA50, it looks like I might have a 0.5mm front focus, but that's narrow enough to attribute to normal AF margin of error, right?
Thanks, guys.
Joe
EDIT: Duh, I forgot the most important thing... While I had the test chart set up, I popped on my MF lens and checked it, and it seemed dead accurate.
