Canon PowerShot G1 X Review

Canon PowerShot G1 X Review

Full review from Engadget
The folks at Engadget have posted their full review of the Canon PowerShot G1 X. For the most part they are quite happy with it, although there are a few issues they have with the camera, like the weak battery life.

Wrap-Up From Engadget

If you demand that an $800 camera contributes to your photography with “extras” like high ISO, interchangeable lenses or exceptional macro prowess, then the G1 X has rivals that are perhaps more worthy of your consideration. However, having used the G1 X heavily for a few days, we can look past its weaknesses — even its underwhleming battery life and uninformative OVF — and admit we’ve become quite attached to it. Our affection has everything to do with the large sensor, fast lens and the overall physicality of the camera — its design, feel, and the accessibility of its controls. If you want a tool for capturing high-impact images, and not necessarily for adding impact to your images, then the G1 X ought to suit you fine.
