Samsung GX-20 Review


The Samsung GX-20 is a 14.6 megapixel, mid-range DSLR camera, which temporarily led the megapixel race when it was first announced back in January. Since then Sony have also unveiled a 14 megapixel camera, the A350, so Samsung no longer have everything...

At first glance the Samsung GX20 simply looks like an incremental upgrade of the GX10, with relatively few additions on offer apart from the headline-grabbing 14 megapixel resolution. Whilst the increased image size is certainly worthy of attention,...

Samsung GX-20 Digital Camera Review


The most notable quality of the Samsung GX-20 is its unpretentiousness. It is a smart, well-designed, functional DSLR that doesn't pretend to be more than it is. Having said that, it doesn't need to. The GX-20 looks like a professional DSLR should: it...

Basically it is the Pentax K20D in other clothes. I like the look of these clothes :). The camera is fast to operate and focus (SDM lenses improve focus speed even further). It offers excellent functions [water resistant (shoot in the rain), pixel...

The Samsung I have does NOT have the 2sec delay hot pixel issue of the Pentax K20D. However, the firmware offered to K20Ds will soon be offered for the GX20 via Samsung's site - where you can download the manual.
