Sigma 50mm F1.4 EX DG HSM

Review Date: Aug 7, 2011 Recommend? | Price paid: $500.00

 
Pros: The lens is wonderful IF your image is in focus (which is unlikely).
Cons:
FOCUS, FOCUS, FOCUS.

I thought I had a good copy since it was relatively new. Sometimes photos would be in focus and the clarity and Bokeh were amazing. In fact I was so happy I rated this a 10 a while back. That was before I lived with the lens for a year.

You just can't trust the lens. It's actually very difficult to determine when the lens is going to mis-focus.

Sigma will recalibrate it, but that is a hit and miss prospect too.

I'll never buy Sigma again just because of this POS lens.

I'll quote the Wesley from the Princess Bride.

If you buy this lens, "BE PREPARED FOR DISSAPOINTMENT".

I'd rate the lens a 2 now. Just because it looks good on the camera.

Pros: Image quality, durability, focus, included hood
Cons:
Weight, Price, Not a great landscape lens

I was a bit worried about purchasing this lens because of the focus issues that are detailed on FM and various reviews.

My copy focuses well close up and at a range up to 20ft away. I use it mostly for portraits so I wouldn't use it much outside this range. I'm using the lens on a 5d, so I have no micro focus capability.

I think many (but not all) of the focus issues are with people trying to use the lens at f1.4 beyond 10ft. DOF is razor thin at f1.4.

Clarity, contrast and color from this lens are amazing. The bokah is creamy and smooth. This lens is sharper at f1.4 than my Canon 24-70L at f2.8.

I also tested the lens against the Canon 1.8 50mm. The results of that test... The Canon 1.8 is a great little lens for $100.00. At f1.8 the Canon was nearly as sharp as the Sigma at the center of the image. The Sigma was sharper nearer the edges of the frame. And of course the Sigma Bokah was much nicer than the fantastic plastic.

I would highly recommend this lens for someones main prime lens on a full frame camera. I would just be sure to do a lot of testing in the 15 day return period that most vendors allow, to make sure you have a keeper.
