I was asked to shoot one of Mushna's friends' wedding here in a few weeks. I was concerned with my lenses at the shorter/wider end so I went to Pictureline to look at options.
Part of me really wanted to go full steam ahead with the 24-70 f/2.8L, but I ended up settling for a couple of primes instead, the Canon 50 mm f/1.4 and the Canon 35 mm f/2. While the L glass would have been nice, I think these two lenses will do just fine, plus this combination was about $500-$600 cheaper than the 24-70.
I headed out for some test shots the other night. These are pretty much straight out of the camera, some sharpening applied in Adobe Camera Raw because I shoot in Raw.
The Canon 35 mm f/2:
The 50 mm f/1.4:
Pixel peeping, I find the 35 mm might be slightly sharper than the 50, but overall, both lenses seem to perform really well.
The 35 mm suffers from some chromatic aberration and softness at the edges, but it seems to be very slight on my cropped sensor body.
I'm happy with both purchases.
