This tele-converter produced very good resolution on my G9. If you want a field-of-view equivalent to a 420mm lens on 35mm film cameras, but not all the time, this is a good choice, assuming you already have a G7 or G9. If you are a frequent user of such long focal lengths, you will likely prefer a camera that has it built in, or better still, a digital SLR. There are two main reasons I say this:
(1) this add-on lens completely obscures the view through the optical viewfinder, so you have to rely on the LCD screen for framing your shots. You will need good light to be using a shutter speed that is fast enough to hold the camera at arm's length, like you need to do to see the screen, and the visibility of the screen in bright sunlight can be less than ideal. It can be done. A tripod or monopod would work better, provided your subject doesn't move too quickly or erratically. My percentage of keepers shooting birds in flight, for example, was pretty low.
(2) While the G7/G9 lens zooms from 35mm to 210mm (equivalent in 35mm terms), and this 2x converter gets you out to 420mm at the long end, you can't use it down to the 70mm (=2x35mm)you might expect, as you will run into severe vignetting. I *think* you can use it for all or most of the range above 210mm.
Having said all this, the G9 plus this converter makes for a very small and light long-lens package, for those who already have a G7/G9 or who only require the added reach from time to time.

I have used the teleconverter for a G7 camera for some time and am extremely pleased with the results. It balances very nicely on the camera and allows one hand shooting without a tripod. To me the additional coverage is stunning. For example, I was able to get a close up of a pitcher on the mound at a major league game from the upper deck of the stadium. The picture was very clean. Please note that there is a menu setting which should be used with the teleconverter or wide angle lens. If the menu is set correctly, you will not get the black circle effect that one of the reviewers mentioned. It is explained in the G7 manual.

I recently went to an air show and used the TC-DC-58C lens. I got great, crisp shots! The clarity loses nothing while the zooming abilities gain everything! I would recommend this lens to any amateur who wishes to be a semi-,halfway-decent-, quasi-professional!

Be aware that the lens is bulky, but this should be obvious to the consumer before buying. Because of its size, it limits the ability to use the viewfinder.
