Cheap but limited utility,
Verified Purchase(What is this?)
This review is from: Maxsimafoto - Canon Compatible Conversion Lens Adapter LA-DC58K for G10 G11 & G12.. (Electronics)
Not useless but if you want to put a filter on your G9/10/11 get the proper Canon adaptor which is pricey but has none of the failings of this one. Basic problem is that it cannot cope with the full telephoto range of the camera. If you put only the part that attaches to the camera on then if you move the lend out it will hit the filter (thankfully no glass on glass contact and the camera senses the "lens fault". However, if you add the extension tube then the camera shows vignetting at wide angle. If like me you want a filter partly to protect the moving camera lens then you will want to leave the adaptor and filter on and this does not help.
See also my review of the "wide angle" lens they market with this tube. Wish now I had bought neither of these things and eventually bought the proper Canon adaptor for the G9/10/11.
