With the PowerShot G1 X already here, how does the G15 justify its existence?
Canon Powershot G15 Review
Performance
It takes just over a second for the camera to ready itself from being turned on, which, while not impressive, isn’t particularly bad either. Write speeds do impress, though, as does the camera’s focusing system which is swift in good light, and, thanks to the powerful AF assist light, still perfectly respectable in poorer light.
The viewfinder’s view is partially obscured by the outer barrel of the lens at wider focal lengths (common on such cameras which incorporate optical viewfinders), although this disappears by around 50mm. What’s more concerning is the fact that the parallax error caused by the difference in position between viewfinder and lens is not in any way indicated by any markings, making it useless for accurate framing. Of course, this is not an issue with the LCD; its resolution and viewing angle are impressive, and any issues concenrning its visibility only arise when shooting under harsher light, which is understandable.
