Samsung GX-10


Our Score:


A range of test shots are shown over the next few pages. Here, the full size image at the minimum ISO setting has been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been placed below it in order for you to gain an appreciation of the overall quality.



Note: The GX-10, like many DSLRs, has a wide range of ISO settings, in this case from 100 to 1600 at 1/3 EV intervals. I've only shown samples from the main single-EV settings here to save space and loading times.

At 100 ISO the GX-10 provides beautifully smooth images with no noise at all, although the characteristic Pentax softness is noticeable.


At 200 ISO there is still no image noise visible.


At 400 ISO there is a little colour speckling in the darker areas of the shot.


At 800 ISO the colour speckling is more pronounced, and the image is starting to look a bit noisy.


At the maximum 1600 ISO there is a fair bit of image noise visible, but the performance is still well up to the expected standard.

Hi Cliff. Just wondering whether the GX-10 is COMPLETELY compatible with all the other Pentax KAF Mount lenses, as Samsung's current lenses are not so numerous. i.e. will there be ANY difference in the performance of a current Pentax DSLR lens on a GX10 compared to a K10D? Many thanks for your help and for the reviews.
