comment:After reading about this lens here on Dyxum i decided i wanted this one. Alternatives would be the Sigma 150 f/2.8 macro HSM, but it isn't available for our A-mount and the Sigma 180 f/3.5 macro seems not as good (see Photozone dot com).

Sharpness is very good, so a straight 5. Getting the right DOF needs practising; i use mostly f/8-f/13. Hunting on the 5D is annoying sometimes (on the 900 this is much better), especially getting towards 1:1 and low light.

Colors are Minolta like, perfect. Also contrast is first rate even with large apertures - which i don't use often with this one.

The build is less good than the 24-85 RS (my copy was new), it's a bit more plastic. No comparison to the G's here. Focusing by hand works very nice with this lens, it is a bit stiff on my almost new copy, but i like that. The hood (same as 75-300) goes on a bit stiff.
But it is the macro IQ that counts, think it is a little sharper than the 24-85.

Focal length is good for small insects like butterflies, flies, spiders, bees and flowers. I make photo's of jewelry, modelcars and other "bigger" stuff in a phototent and found the focal length (on a cropped APS-C sensor) too large for this use. So next addition is going to be the 50 macro D..
If i don't need to go up to 1:1 (like bigger items as engine parts, hydraulic gear for work, etc) i prefer the 24-85 RS which has the advantage of zooming and is almost as sharp.

I use the 100 macro with a Sony Carl Zeiss UV protection filter as sometimes towards 1:1 the front element can get very close to the subject and i don't want to damage it.

Photo's other than macro don't have the 3D look of the G's but this is not what the lens is made for. Wide open f/2.8 still extremely good. Bokeh is just wonderful.

Lens fits nicely -if tight- in the LH-1044 case.
