Excerpt: I bought this lens right before a wedding shoot and used it a few times before the big day. Right away I was amazed at the sharpness and quality of the out of focus elements. On the day of the wedding I ended up using this lens 98% of the day. I couldn't stop admiring the quality it was giving. That being said it let me down on two instances where the autofocus took too long to hunt, which made me miss a candid moment or two.
Excerpt: Tested it out at Mt. Rainier. On a crystal-clear day I could resolve climbers on the Emmons Glacier from 11 kilometers (Nikon D800E, tripod). The lens is just right for that "slightly better than being there" look I try for. The minimal vignetting makes panorama stitching a breeze. Only complaint I have is that f16 is the smallest aperature.
Pros: Easily Interchangeable, Fast / accurate auto-focus, Good Close-focus On D800, Lightweight, Nice Bokeh
Excerpt: A great value for the price. Optically, its a big upgrade from the non D AF version of the same lens i previously had - especialy at wide apertures. The lightwieghtness is great, but somewhat scary.. I am concerened about the durability of this lens and its response to even small hits. Focusing is quite, fast and accurate. Lens diameter is a bit too large for my taste. overall a great lens.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Fast smooth focusing, Lightweight, Nice Bokeh
Excerpt: I primarily use this lens for portraits on full frame cameras. I find 85mm to be even more flattering than 50mm. It is sharp at 1.8 but you will have to stop down to really see some amazingly sharp images. When shooting at 1.8 i find that the autofocus has a little trouble, which is completely understandable at that shallow depth of field. I would not recommend this for street photography, but i would totally recommend anyone who has a willing subject.
Excerpt: This is sharp at 2.8-5.6. The AF is as fast and accurate as the 50mm 1.8g. It is pretty light. And for the price, you are getting a bargain. The bokeh are not terribly great. Not bad, but not great. It has seven diaphragm blades, not nine. So you can see that in the bokeh. Overall, you are getting 90% of what the 1.4 gives you, but at less than 1/3 the price.
