Here is a macro prime lens called the Sigma AF 50mm f/2.8 Macro in Minolta/Sony A mount. The only camera that I can use for testing is a Nikon D5200, so I have nothing much to say here...

These were the old style autofocusing which were driven by a screw on the motorized body. Therefore, it is a fully manual focus lens on non-motorized bodies. But who cares about AF when this lens has always been a dreamy smooth to focus ever since!

I've looked at the images a bit with freelensing on my D5200 and it looks pleasing at f/2.8. The truly nice thing here is that the magnification goes to 1:1 (whereas my Nikkors only go to 1:2). 10 elements in 9 groups? That's quite alot of glass/corrections inside! (In comparison, my Micro-Nikkors only had 4 elements).
