Summary: This is quite clearly a great lens. I bought it to be used with my D7100. The combination is perfect. The lens is sharp and focuses really quickly. I have not used it a lot since it's a new acquisition, but I have made some images that convinced me this lens is really good. It's not as bright as the 105mm 2.8, but it's also much cheaper. So for the price I was willing to compromise on the stop of light difference.
Excerpt: I've been using this macro lens for about 6 months now and it's a very good macro lens. I've gotten some awesome shots and when used with extension tubes you get amazing detail in your focus stacks. I love having the extra working distance this lens provides as well. Buy it.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh
Excerpt: Very good macro lens. The 85 mm focal length gets the lens far enough from the subject that it is less likely to cast a shadow on the subject. Fair warning: the lens makes the camera a little front-heavy, so plan on using a tripod for most macro shots. I also like it for a medium-tele prime lens. I use the lens on my Nikon D3100.
Summary: My Canon 100mm/f4 FD Macro lens was my favorite 35mm film lens for nature close-ups. It's still on one of my T60 bodies in my bag... in a closet - awaiting a call that won't come. Canon abandoned the FD lens mount, rendering my gear obsolete, as far as a digital save was concerned. Nikon kept their F mount - and I gave in last fall and bought a D7000 and 35/f1.8 - adding a 50/f1.8 because it was a 'deal'. The 35/f1.8 is a great 'normal' lens - just not a macro lens.
