The Minolta 100mm f2.8 is always reckoned to be one of the best macro lenses on the market, of any make. It's not that cheap but it does 1:1 and is pin sharp. It can also double as a good portrait lens. The advantage of getting a 100mm maco over a 50mm macro is that the longer focal length allows you to be further away from your subject and that increases the DOF. DOF on macros at 1:1 is exceedingly shallow. I've got one and it's very good. Be prepared for very slow AF because the lens has to travel a long way to focus - it's got a focus limiter to minimise the problem - but that's unavoidable and is just a fact of life with true macro. The Tamron 90mm is probably almost as good, but if you get the Minolta you're future proofed.

A question concerning the KM 500mm Reflex AF... In the picture of the white egret there is a highlight in the lower right corner that is circular. If this what is meant by the donut effect?

probably, but if you look closely you will see that ALL the (oof)b/g hilights are somewhat circular in appearance

(the 'ovalling' is caused by the panning of the camera)

And this is a bad thing??? I think it makes for an interesting backdrop, at least on this photo.Thanks for clearing this up for me. I've been seeing something about the 'donut' bokeh with mirror lenses and I thought they were referring to the entire background being an out of focus donut shape.

Thanks!

Jim

it is neither bad nor good, merely inherent in 'mirror' lenses:
