I picked up a new lens recently that I had been thinking about getting for quite sometime. I was torn between the Canon 28mm f/1.8 & the Sigma version. I decided to go with the Canon version because of the size and weight (smaller & lighter). The lens performs decent wide open as you can see from the shot of my son bellow, however if you are pixel peeping on some printed letters at 1.8 you might not be all that impressed. With that said, real world use in regular type pictures are all good wide open.
On a side note, the lens came with the filter on it and I am kind of moving away from them at the moment. I was going to just take it off, but thought I might leave it on for a bit and see how I feel. The extra protection is nice, but I think it looks kind of ridiculous with the filter on it haha. I will do a full post on this subject in the future.
Thank you for stopping by, Rob
