"Standared OEM item that will increase you options"
This adapter and hood is really a great value for those who would like to increase thier options when shooting with thier canon s2,3, or 5 camera. this 58mm adapter tube lets the photographer attach either one of the two canon lenses (wide angle or telephoto), and filters more importantly.

This is a black set which might not match silver canon s3is models, but the matte black will perfectly match you black s series camera. that being said it also matches the camera body build material which is plastic. though not cheap plastic some might want other options like a lensmate or dealextreme aluminum adapter ring. Lensmate also offers a silver adapter. DX offers low priced adpaters but are not perfect and have slight wiggle.

The hood is very important as it will help with lens flares.

Also when purchasing this or any other adapter tube you will need to get a new lens cap as the original lens cap will not fit you camera anymore. but the original was not the safest as it did not really lock onto the threads.

You will have a lot more fun with this attachment and really increase the abilities of your camera. you do not need the wide angle or telephoto lenses as the built in lens is more than adequate. just get a good set of filters, I have a UV, Circular Polarizing, Linear polarizing, and IR. the two polarizers double as my variable neutral density filters.

get this or an alternative you will have a lot more fun with your camera with this modest investment and another modest investment in filters!

"Great addition to my Canon S5 IS digital camera."
The lense conversion adapter and hood make for a great addition to my Canon S5 camera. I am now able to take pictures out in the sun without damaging the lens or filters. Having the ability to add UV filter to the camera is a must.

"The trouble with plastic..."
The hood and conversion adapter are genuine Canon (made in Japan) and have a quality look and feel. The trouble with plastic is that the threads tend to bind. Even a lightly screwed on filter can have a mind of it's own when you try to remove it from the adapter. Also, you cannot use a lens cap when the hood is on, which is a pain.
If I was buying these again, I would pay the extra $$ for aluminium.

"Beware if you have s5 "
I bought this lens adapter to go with my Canon s5 IS. It fits fine, but when you have the outer hood piece on, the pop up flash casts a shadow from the edge of the hood.This will show on every flash photo.

"Nice addition"
Nice addition for for my S3. I plan to get the telephoto lens in the future.
