I love this Lens, although I have only had it for about a month, it has only product great pictures for me.

I would recommend this lens to anyone that wants to get serious about taking good pictures.

, it's honestly not necessary as this lens already produces great, solid pictures

IS is outstanding, can get nearly 80% sharp pictures even at 0.5 second exposure with my steady hands

Excellent picture quality, build quality, image stabilized Etc

Picture are tack sharp

When I am trying to being critical; my Mark 5D III full frame camera, products slightly sharper pictures than my 7D cropped frame camera, however both cameras product sharp, vibrant pictures with this lens when there is sufficient light.

The pictures are as sharp as can be

The pictures are tack sharp and the lens works with very little light, taking the stress off the flash and limiting the flashes and shadows in my pictures

First, at 16mm/f4 I had some serious vignetting and also the picture had the black circular barrel limiting the picture to the radar screen look
