I have one of these matched and cammed to its original Tech III body. Very nice lens. Very nice to shoot 4x5 telephoto hand held! Seems equivalent of about a 105mm lens on a Nikon, though it is a fatter frame, of course. Top shutter speed of '100 on my Compound shutter hand held seems a bit of a stretch, so I have used a monopod the few times I have shot with it. Who knows, though. It might be fine without it...and this one could have a different type of shutter for all I know.

I feel lucky that I got mine in mint condition (probably never used, quite literally) in the three-lens camera kit for a major steal.
