I broke the lens hood on my kit lens earlier this winter when I slipped on some ice. Luckily, the dl survived nicely but the hood cracked on the ring. My question isssss.... are lens hoods interchangeable? does a N*K*n fit a C*n*n & a Pentax fit Minolta? I usually don't worry too much about hoods but with the kit being 18mm, I would like to replace it in order to prevent flares & vignetting. Furthermore, I really don't want to pay $33 from pentax either. I've found a few on Ebay for $8-13 range.
Any help would be, as always, much appreciated!
