I am currently using the G1 with the kit 14-45mm lens. The G1 is getting more use than my Nikon D300 + 16-85mm lens due to the lighter weight being a better match for my back problems. The 16-85mm lens range is perfect for my needs both due to the range and the fact that it has VR. I cannot carry a tripod but sometimes use a monopod. If you take a look at my photo.net portfolio you will see the kind of photography I do. With m4/3 the ideal lens range would, therefore, be around 14-70mm but with some kind of image stabilisation (thus ruling out the Olympus 12-60mm lens). As I see it, I have two choices: Replace the 14-45mm with the 14-140mm Add the 45-200mm I am not averse to lens changing, but frequently find myself in the middle to upper end of the zoom range on the 16-85mm (around 30-60 mm on the m4/3 ratio). I'd be interested in hearing from any members with experience of the 14-140mm and/or 45-200mm lenses. Many thanks.
