For a Canon SX20IS - the Greatest thing since sliced Bread!!
on March 15, 2010
Very simple, but really mandatory in order to be able to use 58mm filters. Bayonett fitting locks securely on camera in the same one that the original Canon hood did. So if you want to use a hood with this, you need to get a 58mm threaded hood. You can get a 3 position rubber hood for about $8 with shipping.
Getting it on took me a couple minutes as the three flanges on the fitting have to be aligned just so before it will screw on. It is a little more difficult to put on than if the Canon lense was threaded. Once on, it feels very secure and I don't see a need in taking it off again.
This will make your original Canon lens cap useless. Again you can get a 58mm one that will work. I got a lens cap included with a 58mm filter set ordered seperatly. So good to go.
This is strictly the ring, no glass. I couldn't really tell from the picture of it. You wouldn't want glass cause the more glass one puts between the lense and the object, it can start to degrade the quality of the shot.
There is just so much more you can do with filters, so this adapter ring is a must have! Shipping was fast! I've always had good luck with Amazon.
