Sigma 50mm F1.4 EX DG HSM

Review Date: Jan 15, 2009 Recommend? yes | Price paid: $440.00 | Rating: 10 

Pros: Well built, sharp, fast focus, great bokeh and color
A bit pricey for 50mm 1.4

I have had this lens for several weeks now. I have used it at a wedding (as the wedding photographer), at a model studio shoot and at a couple of events. It is very solid and well constructed. It is sharp at 1.4 and the color and bokeh are very good. I have not seen any problems with CA or fringing so far. The focus seems fast and right on. I have not experienced any problems with front or back focusing with my copy although the very narrow dof at 1.4 does take some getting used to. Maybe it is the fascination of a new toy, but I can't get enough of this lens and it is destined to become a favorite and I can seeing myself reaching for this lens over my 24-70 2.8L when the 50mm focal range will do. If you get a good copy, I highly recommend it.

Tamron 17-50mm F/2.8 XR Di II LD Aspherical [IF]

Review Date: Mar 12, 2007 Recommend? yes | Price paid: $389.00 | Rating: 7 

Pros: Sharp, good colors, fast focus, light, affordable
Not happy with excessive CA.

I bought this lens because the 17-55 kit lens that came with my Canon 20D had very poor sharpness.

I have used this lens for about a month now. I have been happy with the auto focus and handling. The sharpness is a great improvement over the kit lens and the colors are good.

My one big disappointment is with the amount of CA. I recently went on a camping trip and a lot of the pictures I took included trees with sky behind them. I was excited about some of the pictures when I took them, but was disappointed to find that the CA was excessive enough that I couldn't correct it in Photoshop and was not able to include the photos in my portfolio.

I might try renting the comparable Canon L lens and test shoot both of them side by side and see if I am being unfair to the Tamron.
