Sigma DP2 review


Sigma DP2 Excellent characteristics for shooting in black and white compact; nice manual controls Slow AF system short battery life stiff shutter button some interface annoyances  occasional lockups poor white balance overly blue LCD screen poor video capture.

On one side, the camera renders smooth, film like photos with a broad tonal range and attractive noise characteristics for shooting in black and white Sigma DP2 calls this camera a DSLR in the body of a point and shoot and they're kind of right. It's got the Fovea X3 sensor.

hitch is just a hair smaller than the Nikon and Canon "Sigma DP2" It was often hard to get a satisfied chirp that meant focus was locked, especially in lower light conditions. Many hastily shot shots are blurry beyond help.

The Sigma DP2 Digital Camera is a high-end compact digital equipped with a 14 megapixel Fovea X3 direct image sensor. Featuring Sigma's unique 'True' image processing engine and a 24.2mm 41mm equivalent f/2.8 lens .

 this compact camera provides the same superb image quality in the "Sigma DP2" professional SLR. Furthermore offers five Exposure modes and three Metering modes as well as being equipped with a built-in flash, hot shoe, and 2.5" TFT color LCD monitor.

Sigma 18-200 mm f/3.5-6.3 II DC OS HSM reviews


It’s enough to mention here the Nikkor 18-200 mm VR or the Sigma 18-200 mm f/3.5-6.3 DC OS which, in the 18-55 mm range, fared definitely better than any 18-55 mm kit devices, still performing decently at longer focal lengths.

The OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera. It works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, thereby making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods.

The Sigma 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) HSM Lens offers an "all-in-one" super-zoom lens solution, from wide-angle to long telephoto. DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is sized to match the smaller dimensions used for the image sensor on digital cameras, It accepts smaller filters (62 mm vs. 72 mm) and can focus 7 cm closer.
