Sharp performer

For the most part I'm very happy with this lens. It's pretty sharp wide open and produces tack sharp images up to f11. f16 is good but by f22 there's noticeable softness. Diffraction kills this lens at what is a very useful aperture for depth of field. Forget sharpness at f32.

The lens is very compact and light for a macro. That's good. It lives in my bag and I use it often. Color is neutral if a bit low in saturation. Contrast is also just a tiny bit low, though both of these factors are easy to correct with a little processing. I generally get good results with autofocus, though that is slow and there is no focus limiter on the lens. Since very close up work requires manual focusing anyway, I don't think that's a real problem.

The lens works well for tight portraiture like head shots. The bokeh from this lens is beautiful, producing great low depth of field images.
