Playing with a 1D Mark III and 24/1.4L
While the 28mm/1.8 and 50mm/1.8 featured in the previous photos, this set is with my friend's Canon 24mm/1.4L a few days before he picked the camera up and took it home. A different friend and I met up for lunch, he brought his Tamron 17-50 (for crop bodies, oops--hence the dark corners) as well as his 24-70/2.8L with his 40D to play. We had a lot of fun.
The daytime shots are with the Tamron 17-50 and Canon 24-70/2.8L... the evening shots are with the 24/1.4L. I didn't think the 24/1.4L would be that different from the 28/1.8. I was wrong. The tad wider is nice, the extra half-stop is nice, but the lens quality is significantly better. It's also much more expensive. The differences might not be huge on paper, but as it was low-light and I was shooting wide open, the 24/1.4L produced output that just looked better.
I'm not the best judge, since I'm mostly still in P&S land myself...
