I just ordered a Canon EF 50mm f/1.4 USM and the lens hood (I get hoods for every lens) and B&W UV filter. I found out later they make a higher-cost model coated to combat lens flare.
The 50mm f/1.4 isn't a cheap lens, and I'll gladly return my filter and upgrade if it makes any difference. If I use the hood, though I'm wondering if it really matters.
Thoughts, anyone?
John
