Excerpt: I bought this lens mostly for macro photography, and it works great for that purpose. I have tried using it on some sports (children's indoor basketball in fluorescent lighting) and found it to be very slow focusing.
Pros: Easily Interchangeable, Nice Bokeh, Strong Construction
Excerpt: This lens fills two needs, fast aperture in a medium telephoto, and close 1: 1 macro focusing. Images I've made so far are sharp and bright. I've noticed that according to my Nikon D7100, the lens is not as fast at close focus.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh
Cons: Heavy, Lens Slows Close Focus, Lens Wshade Is 7" Long
Excerpt: I cannot stop loving this company called B&H. All about them is good. I had to write about them at the beginning of my review because they offer the best in everything. From products, services, etc... The lens I did not use it yet too much, but I can say that is a really good macro lens.
Pros: Easily Interchangeable, Fast / accurate auto-focus
Excerpt: First off, I want to say I have NO complaints about purchasing this lens... Really sharp, super creamy bokeh, smooth focus, great colours and the lens itself just looks simply gorgeous.... Very solid feel, and works well with APS-C cameras (I have a D5200).
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
Excerpt: I'm using on D3200 crop sensor camera. I've used it for macro as well as product shots and find the lens sharp and easy to use. It does hunt for focus, but I shoot on manual focus with a tripod most of the time so this is not an issue. I find it also takes good portrait photo's with a decent bokeh.
Excerpt: I have had this lens for a few weeks now and have taken about 300 shots with it. I am using it on my Nikon D7000. So far, so good. Auto focus is not as fast as some other lenses, but this is a macro after all. It is well built and feels very sturdy.
Pros: Consistent Output, Easily Interchangeable, Nice Bokeh, Strong Construction
Sigma 105mm Macro lens is a great lens for close Ups

Excerpt: This is as sharp of a lens as I own. good contrast. No noticeable lens distortion in the corners; barrel, pincushion. I own two Nikon macro Zoom. They are great lenses; sharp but not as sharp as the Sigma.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh, No Noticeable Distortion
