If a full set of camera controls isn’t your thing, or if you’re considering this camera for a less-experienced shooter, the G3 also includes Panasonic’s iA fully automatic shooting mode, as well as the semi-automatic iA Plus mode that lets you adjust things like white balance, shutter speed, and aperture using simple icon-driven sliders.
The benefits of touch also find their way into the realm of autofocusing, where you can select a subject to track by touching it on the screen. Furthermore, the new Pinpoint AF feature lets you select a very specific point in the image to focus on. Tap a spot on the screen and the camera zooms in on it; then, you can select an AF point within this zoomed-in area. This is especially useful for macro shooting, where the camera might select the wrong point in conventional AF. This mode works best with a tripod—using it while handholding the camera can be difficult.
No matter how you use AF, the G3 focuses very quickly. While we can’t perform our normal lab test for cameras with contrast-detection AF systems, we’re sure that most users will be pleased with the camera’s focusing speed in all but very dim situations. Panasonic achieves this speedy AF in part by doubling the rate of information readout from the sensor from 60 frames a second to 120 fps when autofocusing. Doing so constantly would generate too much heat, according to the company, so it occurs only for AF, not during video or image capture.
Burst shooters can choose between 4 fps at full resolution or 20 fps with the pixel count reduced to 4MP. In the second mode, the camera leaves the mechanical shutter open and samples from the sensor, the way most compact cameras do. With either mode, you can shoot an unlimited number of JPEGs until your card is full, or up to 7 RAW frames. As with any EVF camera, the finder blanks out during bursts, so if you want to pan along with a subject, you may find it difficult compared with using a DSLR’s optical finder.
HD video from the G3 looks very nice, with a top resolution of 1920x1080 pixels at 60 interlaced frames per second. If you prefer progressive capture, you can step down to 1280x720 pixels at 60p. Continuous AF is available during capture, and you can also use touch tracking to select a subject to follow. While there is a built-in stereo mic atop the camera, there’s no mic input. Serious videographers interested in a Panasonic ILC still have to look to the GH2 for that.
The Bottom Line
Once again, Panasonic has created a very impressive ILC in the G3, combining fine imaging with a well-evolved touchscreen experience. Users who want to exploit RAW shooting should take some time to experiment with noise reduction.
If you’re not that type, but still want to shoot RAW, you might consider the Olympus Pen E-PL2, a camera that also gives you sensor-shift image stabilization that works with any lens.
The G3’s kit lens is stabilized, though, and for general shooters looking for a DSLR-style ILC at a modest price, the G3 would be a good choice.
