Wow. That’s a great deal!
Yes, I read tons of reviews about it before I bought it. I wanted a really good prime lens that would also do macro. So I dropped the $1000 on it. Macros were beautiful but when I went out to take some portraits, the lens vignetted badly on any aperture of f8 or lower. So I returned it. It may have just been a bad copy, but I wasn’t going to settle... I got the Sigma 105mm Macro and I couldn’t be happier. Fantastic, sharp photos edge to edge. No vingetting unless it’s wide open and even then, very little. And it was $400 cheaper....
