Excerpt: These include a fixed LCD monitor (the G12 offered a swivel monitor); a 12MP 1/1.7” image sensor (the G12’s sensor was 10MP); and perhaps most significantly, major changes to the lens system. The focal length of the lenses of both cameras is identical (a 5x zoom lens with 28-140mm equivalent) and both have a built-in image stabilizer, but the zoom changes on the G12 were f/2.8 to f/4.5 while the G15 aperture changes are f/1.8 to f/2.8, which allows for images with a...
Summary: The ratings awarded to a product are derived from a number of tests and calculations, keeping certain important factors in mind. These factors consist of features, performance, quality and value for money. In case of software and some other categories, build quality might be replaced with ease of use or ease of installation. Products are compared with other products in a similar price range or product category.
Summary: DPReview.com doesn't try it with the G15, but when they try it with the pricier Canon PowerShot G1 X (*Est. $750) , the software leaves seams, stitching errors and a bent horizon. Like others in its class, the Canon G15 has a USB port to hook up to a computer and an HDMI port to attach to an HDTV.
Pros: Outstanding photos, even in low light, Snappy performance and great handling, Rock-solid build, Big-camera features like a viewfinder and hot shoe, Fits into a jacket pocket
Cons: Video mode offers little manual control, No in-camera panorama
Conclusion: Although the PowerShot G15 is a good camera, reluctantly we’re getting off the small-chip G-series merry-go-round – especially at its list price of $499. We’ve endorsed them for many years but times have changed. Although this is a solid, nicely-featured point-and-shoot, there are now many and much better Compact System Cameras with larger imaging sensors available that are also much more responsive (3-plus fps).
Pros: Bright f/1.8-f/2.8 5x zoom, Quality stills and videos, Excellent image stabilization system
Cons: Better alternatives available, Pokes along in RAW, Very noisy at high ISOs
Summary: The Coolpix P7700 offers an impressive feature set, a longer zoom range than most of its competitors, a fully articulating LCD, and very good photo quality. Unfortunately, it is marred by very slow write times, especially in RAW mode which makes continuous shooting a chore, and really forces you to use the fastest memory cards available for best performance.
Summary: The Canon PowerShot G15 is an enthusiast-level camera built into a compact as opposed to an interchangeable lens system. This may leave it short on some features, but where it doesn’t compromise is on picture quality and manual controls.
Excerpt: Updating the Canon PowerShot G12 released approximately two years ago, the Canon PowerShot G15 is a significant step up from its predecessor with an updated processor, new lens, higher quality LCD screen, lighter weight and expanded high definition video recording capabilities. Regarding similarities, the optical zoom remains somewhat similar at 5x (28-140 mm f/1.8-2.8). Just like the G12, the PowerShot G15 also shoots in RAW as well as 720p video.
