Hi, yes this is the one. I bought from Amazon.com.
Sorry, don't have any pics of the setup now, but it will not hit the attached macro lens that I used with. The adaptor comes in 2 part. If you attach the first part, u can shoot only wide angle at 28mm, you cannot zoom in.
If you attach both parts, u can shoot tele and macro, but not at wide angle. Hope this helps.
The following shot is taken at night at Lower Pierce Reservoir with the G10, Opteka +10 diopter macro lens, Raynox DCR250 +8 diopter macro adaptor, inbuilt flash, FEB -2/3, DIY diffuser, 1/60s, f/4.5, ISO100. Pretty happy with the performance of the G10.
