Present-day models

Mainstream DSLRs (full-frame or smaller image sensor format) are currently produced by Canon, Fujifilm, Leica, Nikon, Olympus, Panasonic, Pentax, Samsung, Sigma, and Sony. Phase One, Leaf, Linhof, Hasselblad and Mamiya, amongst others, produce expensive, high-end medium-format view-cameras.

• Canon's current EOS digital line includes the 1000D,^[30] 450D,^[30] 50D, 5D Mark II, and the 1Ds Mark III. Canon's latest cameras, the 500D, 7D, and 1D Mark IV were introduced in 2009, while the 550D and 60D were introduced in 2010. As of January 2010^[update], all current Canon DSLRs use CMOS sensors.
• Fujifilm currently sells the Fujifilm FinePix S5 Pro DSLR, compatible with the Nikon F-mount lens system. It is based on the Nikon D200 camera body, but utilizes Fuji's sensor technology (Fujifilm SuperCCD SR Pro) and menu system. Fuji previously offered the Fujifilm FinePix IS Pro, which has the unique ability to capture light in the infrared and ultraviolet spectrums.
• Nikon also has a broad line of DSLRs currently including the D3100, D5000, D90, D7000, D300S, D700, D3S and the D3X. The D3, announced in August 2007, is the company's first full-frame digital SLR.^[31]
• Olympus makes DSLR cameras and lenses as part of the Four Thirds System. Current Olympus models include the E-620, E-30 and E-3. Unique features include a smaller size, an effective sensor dust reduction system, and in-body image stabilization, along with a crop factor of 2 (compared to 1.6 in most DSLR's) and an aspect ratio of 4:3 (instead of 3:2). Four Thirds lenses are especially highly regarded.^[32][33]

Pentax K-7

• Pentax currently offers the Pentax K-5, Pentax K-7, Pentax K-x, Pentax K-r and the medium format Pentax 645D,^[34] while Samsung (in collaboration with Pentax) offers the Samsung GX-20, a clone of the K20D. Innovative features include in-body image stabilization, dust reduction system, use of standard AA batteries in the K-x and K-r, weather-proof sealing in the K-5/K-7 (first introduced on the K10D, and otherwise found only in more expensive semi-pro models like the Nikon D200), and adoption of Adobe's DNG standard raw image format. Also, they offer extensive backwards compatibility, accepting all Pentax K mount lenses made since 1975 (though the automatic light metering functionality of some early lenses does not work).
• Sigma produces DSLRs using the Foveon X3 sensor, rather than the conventional Bayer sensor. This is claimed to give higher colour resolution although headline pixel counts are lower than conventional Bayer-sensor cameras. Their current model is the Sigma SD14. Sigma is the only DSLR manufacturer which sells lenses for other brands' lens mounts.
• Currently Sony offer is focused mostly on Entry-level and Midrange cameras, with addition of two professional full-frame DSLRs: α900 and α850. Entry level offer is made of two cameras: Sony Alpha 290 without Live View and Sony Alpha 390 with it, and tiltable LCD. Midrange cameras are Sony Alpha 450, cheap, classic DSLR without Quick AF Live View, though bigger viewfinder, Sony Alpha 560 and Sony Alpha 580 featuring video recording, 3D photography and set of more advanced functions, and finally Sony Alpha 33 and Sony Alpha 55 featuring full time phase detection autofocus during video recording as well as continious shooting of up to 10 fps. The α series offers in-body sensor-shift image stabilization and retains the Minolta AF lens mount.
• Hasselblad, Linhof, Leaf, Mamiya and Phase One, amongst others, produce medium format-sized (6x4.5 cm., 6x6cm.) view-cameras, which produce high resolution digital images. Their sensors (over 60 megapixel in some cases) are able to capture much more detail than the full-frame and smaller sensors found in DSLR cameras.
