Sigma 70mm f/2.8 EX DG Auto Focus Macro Lens for Nikon AF Cameras

This lens is not designed to be a sports/action type lens so if you use it in the manner in which it was designed to be used you will not be disappointed. I own the Sigma 150mm f/2.8 and now this 70mm f/2.8 and I would not hesitate to recommend either lens.

This lens has the sharpest focus of any lens I have tried in this range. It is fast focusing in either manual or auto focus. Used an array of different types of photography is has performed flawless. If there was one thing that is a draw back to this lens it would be that if you use the auto focus at the highest macro settings the motor hunts focus. This is the only fault I have had with this lens, but I use the manual focus most of the time so it not a deal breaker for me. Beautiful finnish and heavy duty construction make this lens one of my favorite lens to use for macro and portrait work.

This is my sharpest lens hands down...and the standard by which I currently compare all other lenses for sharpness. Primarily I use this as a normal lens for portraits and product photography, but it excels as a 1:1 macro lens for tiny objects. The blurry background is especially nice at the close-up range used for macro (in fact the depth of field is remarkably slim at widest open aperture). My one complaint would be this lens' tendency to occasionally have trouble auto-focusing, which means it will take awhile to cycle all the way to one end of it's focus range, and then back again (there is a focus-range limiter switch on the lens which can help mitigate this to a certain degree). This only happens if the subject matter isn't presenting a definite edge or contrast area for the autofocus to lock onto, and is not a deal-breaker at all. The nicer the auto focus module of the camera body, the less of an issue this is. For example, I used to use a Nikon D200 with this Sigma 70mm, and it was prone to having trouble autofocusing. With my D7000, the autofocus unit of the camera is much better, and the lens behaves much more dependably. Keep in mind that I am talking only about using auto-focus, which for macro work is a non-issue if you're using manual focus. I just happen to have ended up using the lens for more non-macro types of work, which is not what this lens was specifically designed for. In short, this is a marvelous lens which I can highly recommend, having used it continuously for the past three years, especially for true macro close-up work where sharpness counts.

This lens performs, looks, & handles as if it was manufactured by one of top name-brand lens makers.
