Excerpt: Sigma needs to address the hardware_circuit board_issue on this lens. It's not fully compatible with the camera. Sigma should not tell users that it is camera's problem when they have to scroll one step at time to reviewing a photo. Also, the focus is a hit and miss as well.
Summary: I bought this lens as a low aperture wide angle lens for weddings. There is something bad with the focus. I put the focus point on my subject in a wide shot and it ALWAYS focuses on the building behind the subject instead.
Summary: This was my first non- Nikkor lens. I had done considerable research before I bought this lens. Everybody loved it, and I had hoped that it would enrich my photography experience. Unfortunately, my copy had an autofocus problem. It would focus behind the intended focal point.
Excerpt: The good:it is light weight.
The bad: it is not as sharp as it should be for a 2.8 lens.
The ugly: the fact that I was anticipating a great lens from the reviews.
Will stick with Nikon from here on out. Just got a Nikon 24-70mm f/2.8 and its everything it was promised to be. Excellent lens.
Summary: I bought this lens to use with my 7D for video, and it was working great. Range of the lens, and constant aperture, plus the stabilization are great! Unfortunately, my lens got "bumped" during a shoot. It wasn't dropped, someone bumped me with their camera, with some camera to camera contact.
Summary: I bought this lens to take photos of our newborn baby. I rented it beforehand along with another I wanted to try, and chose this one based on fast relatively quiet AF, adjustable zoom, fast enough aperture, and OS. My rental copy was perfect. no front or back focus issues on my D7000.
Excerpt: The copy I have bought last week has a AF calibration problem within the focal lengths of 17-28 mm. And it also performs some weird AF operation. So it is packed up and goes back tomorrow.
AF sometimes fails when it's run from infinity to a close up subject.
Excerpt: I bought this lens in hope that I would be able to handhold it at 50mm f4 at 1/25 sec. For me to be able to do this two things were necessary:1. it needed to be sharp at f4 from center to corner and2.
Excerpt: Just got it. Not so happy with is. Found significant front focus mostly 20-40mm, few time right on (5% chance). When in the range of my eye sight, manual focus was consistanly better than AF. When focused, it was sharp.
