Summary: Amazing lens! I have always wanted to get into Macro Photography, and upgrading my gear was something that was hard for my pocketbook. That being said, I decided to choose the Tamron lens over the Nikon lens because of the price and it's reputation from past reviewers.
Summary: I am very disappointed, when I put it on the camera (D5200), I realized this lens is not a constant f2.8 when you get into the macro mode. I know find out this lens is only 2.8 at 10 feet to infinity.
Excerpt: I use this with a Sony A77. I find it remakable. Everything I've shot so far has been handheld and I am very pleased. This is the first macro capable lens I've owned and I am impressed with it.
Excerpt: I use this lens primarily for macro. Image quality is at least as good or better than my old Micro Nikkor 200mm f/4 AI-S (manual focus lens) and has much less chromatic aberration. The autofocus works well and the magnification goes to 1: 1.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Excerpt: I shoot mostly macro and this lens reproduces 1: 1 at its closest focus distance, has excellent IQ, decent AF performance, pleasant bokeh, acceptable but not stellar build quality, and is bargain priced.
Excerpt: This lens is amazing. I'm able to get just a few inches from my subject and take beautiful, sharp and detailed images. The auto focus is a bit louder than I'm use to, but the quality of my images more than makes up for that small annoyance. The bokeh it creates is just as beautiful also.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
