Excerpt: I originally bought this lens intending to use it at f/1.4 - but was immediately disappointed. When I first shot some test images, I thought there was something wrong with the lens. Soft edges, bad chromatic aberation, low contrast - not what I would expect for the price.
Summary: I own 2 of these. It's my favorite lens of all time for both stills, and particularly video (i use it on Nikon bodies, Canon 5d with an adapter, and on the Canon c100 and c300. a little barrel distortion...pretty pronounced at close focus. people say it's not sharp wide open..
Excerpt: Between f2.8 and f11 this lens is very sharp and has excellent contrast. At f1.4 it's going to be softer and lose contrast. There aren't many lenses out there that are good wide open at that aperture. Used correctly this lens is great and has a nice field of view.
Pros: Durable, Good Normal Lens, Handheld Low Shutter Spd, Rugged, Strong Construction
Excerpt: I have other Nikkor lenses that I'm very happy with, but I was dissapointed by the color fringing in the highlights when shooting all the way open. I noticed the fringing (chromatic aberration possibly?) more so when shooting film, however did not see as bad when I put on a Canon 60D via converter.
Pros: Durable, Easily Interchangeable, Rugged, Strong Construction
Excerpt: this is a pretty good lens but I was dissapointed at it's sharpness, given all the other reviews. I bought it to use at 1.4 and it has a LOT of color fringing of highlights at 1.4 & 2 (and some even at 2.8). It is also very noticeably soft until 2.8 or 4.
Excerpt: Rarely do I get excited so quickly over a lens. Even though lenses are key to great photo. WIth this lens I've taken maybe 1000 photos with it (2 weeks since it arrived in my hands) and already I'm thinking I should get a back up. I do not have any other lenses that I feel this way about.
Pros: Consistent Output, Nice Bokeh, Rugged, Strong Construction
Summary: I have to comment that I think that many people are missing the point of this lens.... It is really two lenses in one. It is SUPER sharp from f2.8., however, from f1.4 to f2.8 it is soft, vignettes, but the images is takes here are beautiful and dream like.
Pros: Small size., Build quality., Two lenses for the price of one., Vignettes, soft(ish) wide open, Excellent and direct focus through
