Summary: First I tried one of the $10 cheapies offered by many on Ebay. It was loose and sloppy, always felt like it was going to fall off. This is a very well constructed adapter, works much better than the non-Canon versions, and is very solid. And, contrary to all the descriptions I have read about it, saying it is 3 inches long, it is actually only 1 7/8 inches long - so quite compact. Expensive, but a far better tool. I highly recommend it over the independant-made adapters.

Summary: Keep in mind that you can't use this product unless you buy an external flash. The built-in flash results in harsh shadows on the left edge of the photos. canon's response Thank you for your inquiry regarding the PowerShot G6. We are sorry to hear of any issues with the Conversion lens. When using the built-in flash, a portion of the image may be blocked by the converters and appear dark. Please refer to page 186 of the camera manual for detailed information.

Este adaptador lo utiliza una cámara PowerShot G6 de Canon, lleva un sistema que se pone fácilmente y en pocos segundos, ideal para ir cambiando según se necesiten, ya que dependiendo de la foto deseada puede hacer falta un adaptador como este o simplemente un gran angular o etc….
