Canon PowerShot G15 Digital Camera {12MP}

Canon G15: f/1.8 compact with full manual control and RAW

The G15 is built around a 12MP 1/1.7" CMOS sensor paired with Canon's Digic 5 processor, pulling ISO up to 12800 for low-light work that most fixed-lens compacts of its era couldn't touch. The f/1.8 maximum aperture at the wide end is the real story here: it lets in enough light that you're reaching for higher ISOs far less often, and it gives you meaningful subject separation on a small sensor. The 28-140mm equivalent zoom covers street to short telephoto without requiring a bag full of glass.

Shoot RAW, dial in exposure compensation across a ±3 EV range in 1/3-stop steps, bracket, and work through full aperture and shutter priority alongside manual exposure. There's also a hot shoe if you need more flash power than the built-in unit's 7-meter range provides. The optical tunnel viewfinder is a genuine usability advantage in bright daylight. At 352g and 107 x 76 x 40mm, this camera fits in a coat pocket and still gives you the control layout of a camera twice its size. For photographers who refuse to give up image quality or shooting discipline just because they're traveling light, the G15 makes a strong case.

Who It's For

Travel photographers who want RAW files and manual controls without checking a bag will find the 28-140mm f/1.8 zoom covers most situations in a single pocket-sized body. Street shooters benefit from the optical viewfinder and fast-aperture lens, which together keep shooting discreet and viable in low light. Documentary and journalism work fits the G15 well as a capable backup or always-on carry camera, given the full PASM exposure modes and hot shoe for auxiliary flash. Macro photographers get 1cm minimum focus distance, opening up close-up work that most zoom compacts won't allow.

FAQ

What makes the f/1.8 aperture useful on a 1/1.7" compact?

At the wide end of the zoom, f/1.8 lets you shoot at ISO 400-800 in low light where you'd otherwise need ISO 3200-6400 on an f/2.8 lens. You also get genuine background separation on the G15's small sensor-not dramatic, but noticeable at close focus distances.

Does the optical viewfinder actually help?

Yes. The tunnel viewfinder gives you a real-time optical view in bright daylight when the LCD washes out. It's not a full-frame view and there's no autofocus confirmation, but it's a genuine usability win for outdoor shooting.

Can you shoot RAW reliably on this camera?

Completely. The G15 records RAW alongside JPEG, uses SD cards for storage (no proprietary media), and the Digic 5 processor handles the file writing without lag. RAW files are Canon's native CR2 format, compatible with Lightroom and Adobe products.

How does the zoom compare to other compacts from that era?

5x optical zoom (28-140mm equivalent) is conservative for 2012 standards. Rival compacts like the Nikon P7700 offered 7.1x, but the G15's wider aperture throughout the zoom range gave it a low-light advantage those cameras couldn't match.

What's the burst shooting situation?

2.1 fps in standard continuous mode. Canon claims 10 fps is possible in a High Speed HQ mode, but that's restrictive. For most shooting, expect 2.1 fps, which means this isn't a camera for tracking fast action.

Will the built-in flash be enough?

The built-in unit reaches 7 meters effective range. For indoor events or bounce-fill work, you'll want the optional external flash on the hot shoe. The camera supports all standard flash modes including slow sync and second-curtain.

How does battery life compare to DSLRs?

350 shots per charge (CIPA rated). That's solid for a compact and means one spare battery covers a full day of shooting. The NB-10L is also used in some Canon EOS models, so batteries aren't proprietary.
