Summary: Awesome lens! Creamy bokeh. Purchased used and this one doesn't focus too well. Seller worked with me and gave me a discount for keeping it. I use it for portrait work so manual focus is fine for my needs. This is an artistic lens so it isn't your everyday carry around type.
Summary: This lens is awesome! I just changed from canon to nikon and I needed a portrait lens. I was looking at what I previously had, the nifty fifty, and the 85mm for my portrait lens but then decided that if I'm upgrading, I should upgrade!
Summary: We took a leap of faith on this one, after a disappointing experience with the 135 f2. So far this is just excellent. It's sharp enough at f2 and, more importantly, focuses accurately and consistently on the D800. It focuses much quicker too, likely because there isn't as much glass to push around.
Summary: You won't get the same bokeh you see from a 135, but this lens does an amazing job with portraits. I wouldn't shoot group shots with it and even couple shots will be hard as you are backing up, backing up, backing up.
Excerpt: After a few nights of tinkering with this lens i can understand how others were unable to get the best results. Which is not to say that this lens is difficult to use - it just needs more attention to operate than an 85 1.4 (more things to setup w the defocus control and additional button you have...
Pros: Durable, Nice Bokeh, Rugged, Strong Construction

Summary: Had to return the lens as the images were only a little bit better than the kit lens ( 18-105 ) that came with the camera. For $1100 I did not think it was worth the very small amount of increase in picture quality.
Summary: This is built for portraits! I've used Nikon's 50mm F/1.4, 85mm F/1.4 and this one. these are different focal lengths, but the 105mm is my personal favorite. Especially love the Bokeh control dial - for front and rear blur control. The lens is heavy and pain to lug but the pictures are just stellar.
Summary: I tested it thoroughly before buying... well, a Zeiss 135/2 and a 105/2.5 AIS. This lens seems to have no weakness, except some CA and purple fringing wide open. Here the Zeiss is vastly superior, especially in handling bright light sources. And of course it is sharper.
