The G10 lets you go hog wild
If you have fun experimenting with F-stops and shutter speeds, and diddling with exposure controls, the G10 lets you go hog wild. I dug deep in the manual and found that the G10 has more settings than my SLR. For instance, there’s a handy Exposure Compensation dial–plus and minus two stops in 1/3 increments; there’s also a quick way to adjust ISO sensitivity. (Higher ISO settings let you snap images in low light.)

Unfortunately, unlike an SLR, the G10 doesn’t accept other lenses. It can, however use a Tele Converter (about $110), a device that increases the telephoto range to 280mm. To use it, you’ll need a kit that includes the converter and a lens adaptor (LA-DC58K). Amazon has it for about $150.
