Zoom lenses are expensive. Telephotos lenses are really expensive. But if you want to shove a little extra optical oomph into you camera, this 2x $US50 telephoto adaptor is a killer deal. Just screw 'er on and shoot.
It's as easy as it is cheap -- each lens adaptor is made for whichever lens you're seating it on -- 77mm through 49mm threads -- and about doubles the focal length of your cam. A 50mm lens becomes a 105mm, pretty much. And for $US50, that ain't bad! The thing is pretty, cheap and portable -- three wonderful adjectives, and rare when it comes to photography. [Photojojo]
