I like keeping the hood on too. That is my main objection with the otherwise great inexpensive hoods on ebay. I personally like B+W's thick collapsible rubber hood for ease of use.
I, too, like B+W's thick collapsible rubber hood. So, not to challenge ray_g's opinion, but I later decided to swap it out for one of the inexpensive hoods off ebay. Reason being that I like to be able to slip my camera into my carry-around camera bag and be able to quickly pull it out and be ready for a shot when the situation arises. (note that I'm talking about when I'm walking around town, not when I'm putting the camera bag away for the night) And the concern I had with the B+W collapsible hood is that it doesn't provide the front lens element any protection when I slip the camera back into the bag whereas the inexpensive solid hood does. Hope this explanation makes sense. Oh, and I found that a 48mm snap-cap covers fits nicely into the front of the inexpensive sloping front solid hood so I still put a cap on when putting the camera bag away for the night. Sorta the best of both worlds, although the solid hood does add significant length to the overall lens profile which might be a challenge for some camera bags.
