Customer Review: Works fine for My Canon A640This adapter fits over the Canon A640 lense and is long enough for the lense to be fully extended for zoom--this was an important concern for me before purchasing. This works fine for use with a wide angle or telephoto lense in combination with filters. When used with a wide angle lense and a polarizer filter, it gives a "porthole" effect in the image, but zoomed in further, this effect disappears. Similarly, a telephoto shot not fully zoomed shows this porthole effect.
Customer Review: Solid item
We got this as a back-up to the one that came with the Opteka .45x Wide Angle & 2.2x Telephoto HD² Professional Lens Set for Canon PowerShot A640 A630 A620 A610. It's very solid (aluminum?), yet light.
