Screw right into the end of the lens so you dont have to take out the optic like the extension tubes. Since there are three different strengths you can get a little or a lot closer. Comes with small carrying case to keep them from being scratched.

Reasonably priced, work well ad as usual the order and delivery process was brilliant!

I love stacking these macro filters for maximum closeup photography. Bring your subject closer while utilizing the creative optics Lensbaby offers

Ive only played with mine, but they definitely work. Absolutely huge difference stacking the +2 and +4 on my sol 45. Easy to screw in, love the sturdy Leather carry case. Was a last minute impulse purchase given the July sale and I do not regret.

I really like these filters. Purchased them several years ago and unfortunately lost them. Very happy to own them again. great to get up close when photographing flowers!
