I've got the following lenses: -Panasonic 14-42 kit zoom lens -Nikon 50mm f/1.8 and adapter -Canon FD 28mm f/2.8 and adapter The 14-42 kit lens comes with a hood. I'd like to get hoods for the 50mm and 28mm lenses. Any suggestions on inexpensive hoods? Hoods that aren't huge are preferable to reduce bulk in my camera bag. Thanks.
