how necessary are they?
every time you grab your camera, you have to flip the hood, strugle to get off the lens cap, strugle to get the lens cap back on, then flip the hood over once again to get your cam back into the bag.
back in film days, no hood, one used his hand to block the light
are they really that nacessary
Ken Rockwell always sujest to leave them wrapped in the plastic they came in, and leave them in the box the lens came with
