Conclusion: Overall, the Samsung GX-20 is well-priced and well-put-together. It is an attractive, solid unit, both in terms of its build as well as its performance, and it is unlikely to disappoint. Highly recommended.
Excerpt: Pentax and Samsung enjoy a 'technology partnership' in the digital SLR market, so it shouldn't be too much of a surprise to discover that there are plenty of similarities between their cameras.
Summary: The GX-20 can be viewed as the fruit of a successful manufacturing partnership. Samsung’s electronics expertise has been coupled with Pentax’s long-standing photographic heritage to produce a camera that manages to meet a high specification while not breaking the bank.
Summary: This camera feels and sounds like a beast. And it is a beast. It'll produce very good images at a 14.6Mp size, with practically no noise up to ISO 800. However, its Live View feature is worthless.
Pros: Huge picture size, no noticeable noise up to ISO 800, solidly constructed, optical image stabilisation
Cons: Live View is implemented poorly, no dedicated buttons for ISO or shooting mode, shutter button could be better, loud shutter, slightly soft image quality
Summary: The tweaks and reworked menus can’t hide the fact that the GX20 is basically the same as the Pentax K20D. But the K20D benefi ts from the Pentax brand cachet and has a couple of useful features missing here, which leaves the GX20 in a kind of no-man’s-land.
Summary: 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 have made a substantial number of improvements underneath the surface that add up to make the GX-20 a really compelling DSLR camera.
