Ephotozine have recently posted a review of the Samsung GX-1S DSLR, a 6.1 Megapixel (CCD sensor) Pentax mount Digital SLR camera featuring a large 2.5 inch LCD screen, high speed 2.8 fps up to 8 frames in JPEG mode CCD sensor.
Noise levels at ISO200 and ISO400 are low, as you would expect from an APS-C digital SLR of this level. Shots taken at ISO800 display a little more noise, but the images are still very usable. At ISO1600 chroma noise starts to become more prevalent, with midtone areas gaining a fairly strong pattern of multi-coloured speckles. By ISO3200 things start to get messy. The grey area of our QP card has no grey left in it, instead large flecks of red, green and blue are dominant. However if pictures taken at the ISO setting are converted to black & white, then they still display a good amount of detail and the noise levels are better controlled.
