Sigma launches its new enthusiast compact camera featuring a Merrill generation Foveon X3 sensor and now equipped with a 50mm f/2.8 lens, optimized for macro and close-up photo shooting.

 

50mm f/2.8 lens

 

Sigma’s announcement during this CES 2013 comes as a bit of a surprise. The new addition to the Foveon X3 Merrill series, the DP3 Merrill, features a 50mm f/2.8 lens which, combined with the APS-C sensor, becomes equivalent to a 75mm portrait lens on a 35mm SLR. This lens is also optimized for macro photography and close-up shooting. On the DP3 Merrill, the lens offers a minimum focusing distance of 22.6mm and a maximum reproduction ratio of 1:3. The optics use Special Low Dispersion (SLD) glass and aspherical lens elements, thus compensating aberrations while making for a more compact camera. Its telecentric optical design improves the image quality over the entire frame. Lastly, the lens’ Super Multi-Layer Coating reduces flare and ghosting while enhancing image contrast.

 

3-layer Foveon X3 Sensor

 

Needless to say, the Sigma DP3 Merrill features the latest Foveon X3 AOS-C 46 megapixel sensor. This unrivaled sensor is made up of 3, 4800×3200 pixel layers, one for each RVB color. This innovative design avoids color moiré, making the use of a low-pass filter unnecessary, somewhat like X-Trans Fujifilm sensors on the new X100S and X20 cameras.

 

Sigma DP3: enhanced speed

Aware of previous generation large sensor drawbacks, Sigma highlights the DP3 Merrill’s enhanced processing speed. Featuring a TRUE II double image processor entirely dedicated to the sensor images, image recording and processing speeds are much improved. The continuous shooting mode reaches 7 I/s in RAW format. The DP3 Merrill’s 9 point autofocus now includes a new Face Detection system and can also limit focus range for faster focusing. To further enhance speed, the DP3 features a “Shutter priority” autofocus mode for faster adjustment in a “AF+MF” mode that allows you to manually readjust focus.

The Sigma DP3 measures 12.15 x 6.67 x 8.06 cm, only weighs 400 gr and features a 3”, 900 000 pixel TFT monitor. Video is definitely not the Sigma DP3’s forte, with a 640×480 VGA movie mode, surprisingly

minimal in 2013…
