I'm thinking of picking up the Canon 10-22mm lens. I usually buy lens hood and UV filters for protecion (not here for a debate on the merits).
I have read of people skipping the lens hood for the 10-22 because it doesn't do much and with is small size it offers very minimal protection (mostly just protects from frontal bumps). I'm not opposed to spending money to buy an OEM one. My question is whether the Canon OEM lens hood vignets and whether it's worth it for protection purposes in this case.
My other question is whether I need to buy thin filters for this. I usually use regular B+W MRC filters. Do I need to get thin ones for this lens?
