Compared to... Casio EX-Z750

Below you will find a studio comparison between the Casio EX-Z850 and its immediate predecessor, the EX-Z750. We have included samples for the lowest and highest ISO settings for each camera (ISO 50 and 400).

Note that we are not including the higher ISO settings (800 and 1600 in the case of the Z850) in our standard studio test, as they are not manually selectable and are only available in a couple of Best Shot modes. You can find a studio test shot taken at ISO1600 on the noise test page.

What is immediately noticeable is that Casio has gone for a much more subtle approach to image processing than with the initial EX-Z750 firmware (the ludicrously high default contrast and saturation on that model was reduced in later firmware versions - this is the original version, as tested). And boy does it make a difference; the images are a lot easier on the eye, a lot more natural and a lot more receptive to post-processing. There's lots of detail here, though the additional megapixel appears to make no difference at all, and looking at the results side by side it's obvious that the lens used on both cameras is the same, and that it is probably the limiting factor in resolution terms.

There is a little corner softness, and slight over-sharpening (which you can at least turn down), but overall there really is little to complain about here - it's not a great leap forward, but the Z750 was an excellent performer anyway. Even compared to much 'higher level' cameras such as the Canon S80 the Z850 can hold its own, and as far as ultra compact, fully-featured 8MP models go, it's currently - at ISO 50 at least - almost peerless.
