Debuting back in September 2000, Canon‘s PowerShot G series cameras have gone through several iterations in the year since, losing some of the features that made it popular in the first place – particularly its fast lens. With the launch of the G15, the company has reintroduced the fast lens speed of the original; the new lens covers the same 28-140mm equivalent focal length range as the G12′s, but it is 1/3 faster at f/1.8-2.8 rather than its predecessor’s f/2.8-4.5. With a fixed rather than articulating rear screen, the camera is now about 15% slimmer. At its core is an in-house 12.1 megapixel 1/1.7″-type CMOS sensor and a DIGIC 5 image processor for full HD video recording in addition to shooting crisp images. One of the more notable improvements is the autofocus which Canon claims is 53% faster than the outgoing G12, making this camera the company’s fastest focusing compact camera ever. No word on pricing yet but look for this at fine camera retailers soon.
