I was shooting the Morris Park Community Association Dinner Dance at Marina Del Rey over the weekend and brought the newest lens to my arsenel, the Sigma 85mm f/1.4. I've read many positive and negative reviews over the internet. Its supposed to have stellar image quality (IQ) but heard numerous rumors stating canon makes it hard for 3rd party lenses to work on their cameras. I've had to micro-adjust this lens when I first bought it. The reason I bought this lens is because Canon doesn't make this in 1.4, only in 1.8 and 1.2. The 1.8 wasn't good enough and I heard the 1.2 had slow focusing speed. To I wanted to make this my favorite lens and it produced this image:

However when I used this camera with flash over the weekend, it missed focus 4 out of 5 times. Of course it was only during a shot when Al DeAngleo was speaking. Anyway I had my other camera with the Canon 24-70mm f/2.8  and grabbed a sharp image. So two cameras is always better than one. Always have a backup. Always have a backup.

This lens should however, be shot without flash. Let's see....
