Panasonic Lumix DMC-GH2

For photo and video enthusiasts who want the flexibility and performance of a digital single-lens reflex (SLR) camera without the heft, experts say the compact Panasonic Lumix DMC-GH2 is a viable choice. (The GH2 is not a DSLR but can swap out lenses.)

At 13.8 ounces without a lens, it's lighter than a full-size digital SLR, yet it packs nearly as many advanced features, including full manual control, RAW file support and an interchangeable-lens system. But superb high-definition video is the GH2's marquee feature, thanks to its 16-megapixel Live MOS sensor that delivers both speed and the "highest resolution currently offered by a Micro Four Thirds camera," says Gavin Stoker at TrustedReviews.com.

Great controls, so-so images

The GH2's continuous autofocus lets you lock in and hold your subjects while filming full high-definition 1080p (24 fps) and 1080i (60 fps) video. Critics say the autofocus is notably faster than the earlier 12-megapixel Panasonic Lumix DMC-GH1. Additionally, the GH2's touch-screen controls allow easy transition between focus points without the need for a focus ring, though an array of manual options is available.

Although experts are impressed by the GH2's "superior" video performance in bright and low light conditions, still image quality -- though very good -- drops a "notch below that of a true DSLR" because of muted colors, says PC World's Tim Moynihan. Others find that despite the GH2's ability to shoot up to ISO 12,800, noise surfaces at more than ISO 800. With fast start-up and improved burst speeds at 5 frames per second in full resolution, critics say the GH2 is quick enough for general day-to-day shots.

The bottom line

Overall, experts prefer the Sony Alpha NEX-5N, which provides the best image quality in its class, according to reviews.
