I just picked up the P14-140 f3.5-5.6, and it is wonderfully light, and reasonably compact, given its range. But the lens hood that comes with it is HUGE. It easily adds half again to the length and 1/2" of girth to the lens, completely undermining the lens's pocketability. So, how important/effective do you think these lens hoods are? Would I get flare for days if I just left it at home? Would a collapsible lens hood work as well or better? Are there better solutions?
