Excerpt: I look first the AF-D version of this lens and the results are great, but with this version the results are awesome, very silent focus mechanism, fast accurate, I see soft corners at 1.4 and a little vignette, but this are in the two versions, this is the best low light lens I tested, every people...
Excerpt: This is a very good lens to have in the camera bag for those shots that don't require a telephoto lens, and you want ultimate sharpness in varying light conditions. A good portrait lens. The lens works great with my D810.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I spent a lot of time thinking if I should buy the 1.4 or the 1.8. I tried out both and were very happy with each. Ultimately decided that the 1.4 has better glass and gave me more flexibility..
Pros: Fast / accurate auto-focus, Nice Bokeh, Strong Construction
