Now I've never owned the 100 macro but in 1978 when I shot with the Nikon FM my lens of choice was the Nikkor 105mm f2.5. This Nikon lens was a true classic and I always liked the focal length on film and full-frame digi.
I borrowed the 100 macro and have been trying a few things with it. The first thing I noticed was the Face Detection on the A33 didn't work right with the macro. It would frame the face but wouldn't focus properly on it. No real issue I don't use the feature often anyway... but I thought I would try it.
At this event the lens was a bit short and I liked the angle of view better with the Zeiss 135mm. The first shot is with the 100mm macro. The next two are the Zeiss 135mm.
