Summary: I recently ran into an issue with my beloved Canon 35mm 1.4 L lens. After many years of exceptional quality and loyal service, it started to back focus when photographing an object or subject from that was more than 3 meters away. I find the 35mm focal length to be essential for wedding photography.. especially when it is a prime and can capture subjects in dark situations and help them to pop with its wide aperture.
Summary: I've only had this lens for a week... Wow! Pictures shot at large apertures have a wonderful bokeh separating subject from background and foreground, giving a three dimensional look. I'm so blown away with the picture quality, i haven't paid attention to other qualities of this wonderful lens. I will update this review as I keep using it.
Summary: This lens is very well-made, with a high-quality feel. It is heavy in a good way and feels like a better-made alternative to its more-expensive Nikon counterpart. However, like others, I experienced spotty focus and lower light when shooting wide open. This was with a D800. It never did seem to nail focus accurately at 1.4. Also I compared it to a Zeiss 35mm f2 and there was a distinct difference in color and contrast.
Summary: Been reading about this lens for weeks maybe months, about how great Sigma got it, how they've turned it around, how this is the new benchmark for 35mm f/1.4, it's the king of the bokeh on and on etc etc... let me tell you, IT IS! Since I got this lens it's almost exclusively been on either my D3 or my D4, with the exception of just a very minor (+2 points) front focus that I was able to fix in the camera in under 2 minutes, this lens has been flawless and I grow to love...
Excerpt: After reading countless reviews about this lens for months, I finally decided to buy it. I'm SO glad that I did. It performs beautifully on my Nikon D800! It's tack sharp, even wide open. It's just the right amount of contrasty, and I've been more than thrilled with the images I'm getting from it!
