Samsung EX2

Compact cameras are facing heated competition from a new era of smartphones that are always connected and offer imaging quality on par with compacts that were introduced only a few years ago. As most serious photographers know, however, alongside these advantages smartphones also offer lackluster low-light abilities, impossibly slow autofocus, minimal manual controls, compressed image capture over RAW, run-of-the-mill video specs, nonoptical image stabilization and fixed lenses that offer slow apertures without optical zooming.

Now camera companies are starting to fight back by incorporating the advantages of cell phones into much more sophisticated cameras. For example, a few new compacts offer an interesting development, with several models fitting large image sensors, even full frame, into the efficiently sized bodies. This translates to far better imaging quality over the extremely small sensors that you'll find in smartphones because, all things being equal, larger sensors are able to gather more light. That means a better signal-to-noise ratio, which will result in less image noise, even over the latest smartphones with a lot of megapixels like the Apple iPhone 4S/5, Samsung Galaxy S III/Note II or the 13.1-megapixel Sony Xperia Z.

With many more likely on the way, a handful of new models also incorporate WiFi and the Android operating system. Just like your smartphone, this gives the cameras wireless abilities for accessing camera controls and images from computers or tablets. WiFi adds instant connectivity for uploading images and behind-the-scenes shots to the Internet and social media right from the camera. In short, smartphones are certainly convenient, but if you're looking for an extremely portable camera solution that also offers great imaging quality and pro features, there never has been a better time to look at compacts as a much better choice for shooting from the hip.

Full Frame
Historically, it has been expensive to produce a full-frame digital sensor the same size as the ubiquitous 35mm film plane of classic cameras. Now image processing and chip manufacturing have reached the point where large sensors are finding themselves more common, even in very small bodies.


Sony CyberShot DSC-RX1

The Sony CyberShot DSC-RX1 sports a full-frame CMOS sensor in a body weighing just over a pound. The remarkable RX1 currently sits in fourth place on DxOMark's Camera Sensor Ratings grid, outperforming most current DSLRs and even several medium-format cameras in overall imaging quality. It has a 35mm ƒ/2.0 Carl Zeiss Sonnar T* prime lens with nine aperture blades and an internal flash, as well as compatibility with external flashes and accessories. Pro features include 14-bit RAW files, ISO up to 25,600, a close minimum focus distance of 5.5 inches and a 5 fps burst rate. Full HD video is available in 24p/60i/60p, with several accessories like viewfinders, a thumb grip and an LCD monitor. The 3.0-inch Extra Fine LCD Display panel provides extremely high screen resolution at 1229K dots. List Price: $2,799. www.sony.com

APS-C
APS-C sensors aren't quite as big as full frame, but they offer a lot of imaging real estate. Because of the crop factor of projecting a full-frame circle to an APS-C sensor, these sensors offer a 1.5x to 1.6x equivalent focal length.


Fujifilm FinePix X100S

The design of the Fujifilm FinePix X100S is retro, but underneath the hood is an entirely different story. The X100S updates the X100, with Intelligent Hybrid AF for combining the advantages of both phase and contrast-detect autofocus. Fujifilm claims autofocus within 0.08 seconds in the High Performance mode. The 16.3-megapixel X-Trans CMOS II APS-C sensor and EXR Processor II offer a full-res burst rate of 6 fps for up to 31 frames, 14-bit RAW capture and shutter lag of 0.01 seconds. A unique Digital Split Image feature allows you to focus the camera through two overlays, much like a rangefinder. Video is available in 1080p 30/60 fps; ISO ranges from 100-25,600. List Price: $1,299. www.fujifilm.com


Leica X2

Available in silver or black, the Leica X2 is an elegantly designed compact, though the interior specs are somewhat lacking. There's a 16.1-megapixel APS-C CMOS sensor with 4944x3272 resolution and an Elmira 24mm ƒ/2.8 ASPH lens that provides an equivalent 35mm angle of view. At 4.88x2.72x2.03 inches, the X2 weighs less than a pound, and unlike most other Leica models, autofocus is available alongside the manual controls. There's no video, however. Additional features include a 2.7-inch live-view screen with 230K resolution and a retractable flash. RAW capture is also available in the DNG format. List Price: $1,995. us.leica-camera.com


Sigma DP3 Merrill

Sigma produces not one, but three compact cameras with large APS-C imaging sensors: the DP1 Merrill with a 19mm lens (28mm equivalence), the DP2 Merrill with a 30mm lens (45mm equivalence) and the most recent model, the DP3 Merrill, with a 50mm lens and 75mm equivalence. The unique Foveon sensor offers three layers of stacked photodiodes that capture RGB values independently, unlike typical Bayer sensors that must interpret color information from a checkerboard-like pattern of photodiodes. Sigma fans say this results in very sharp images, even from a compact. All three compacts are otherwise the same, offering a nine-blade diaphragm with an ƒ/2.8 aperture, standard-definition VGA video capture and roughly 15 megapixels of resolution on the 4704x3136-resolution sensor. (Sigma states 46 megapixels of resolution because there are three layers of photodiodes on the sensor.) ISO ranges from 100-6400. Estimated Street Price: From $949. www.sigmaphoto.com

1/1.7-Inch Sensors
The 1/1.7-inch sensors are smaller than DSLR sensors, but still much larger than sensors found in most compacts and smartphones. Several recent 1/1.7-inch sensors employ backside illumination, which exposes the rear of the sensor to light for achieving much better quantum efficiency with a notable improvement to low-light abilities and much less image noise.


Canon PowerShot G1 X

Canon's flagship model for its PowerShot series of compacts, the 14.3-megapixel PowerShot G1 X, was joined at CES last year by the 12.1-megapixel PowerShot G15 as a serious fixed-lens compact solution for pros. The older G1 X sports a huge 1.5-inch CMOS sensor (even larger than the Micro Four Thirds sensor in Olympus and Panasonic cameras) with 4352x3264 effective resolution. The G1 X incorporates a fixed 15.1-60.4mm lens for an equivalent 28-112mm zoom with a variable aperture of ƒ/2.8-5.8. Meanwhile, the newer G15 with 4000x3000 maximum resolution offers a 1/1.7-inch sensor at roughly one-sixth the size of the G1 X. The G15 offers a much faster variable aperture of ƒ/1.8-2.8, with a focal length of 6.1-30.5mm with 28-140mm equivalence. Both range in ISO up to 12,800, and each offers video in 1080p at 24 fps and 720p at 30 fps. They're compatible with Canon Speedlite flashes. List Price: $699 (G1 X); $499 (G15). www.usa.canon.com
