Re: Inner focusing and FA* 300/4.5 ED(IF)

[Bob Keefer]

Hi:   I use the FA* 300/4.5 with the Bogen/Manfrotto long lens mount. It's an OK combination, if a little slower to get mounted up than something more direct. I use it with a PZ-20 and an LX. No trouble with either.   One other drawback besides speed, though, is that the B/M mount doesn't work well at all for vertical orientation.   Unlike another poster, I find the lens crisp and sharp with no vignetting at any aperture.   The lens is clearly designed to be hand held. I often use it hand held for studio portraits with strobes. If you contemplate using it on a tripod, you might consider the F* 300 or the FA* 400/5.6.   Have fun.   Bob
