Pentax X90 review
Although it is only a relatively minor upgrade over the X70, it's enough to put the Pentax X90 into the top bracket of superzoom cameras. Build quality, design and handling are right up there with the best, and the improved performance and battery duration are very welcome. There's still room for further improvement in image quality, but the results are far from disappointing.

Pentax X90 camera review
The Pentax X90 is all about shoehorning as broad a focal range as possible into a DSLR-like chassis, and as such it largely succeeds as a catch all device, being as adept at shooting expansive landscapes as intimate portraits and everything else in between. The trade off is that it is more plastic-y of build than an actual DSLR and of course by being an all-in-one there's no access to a broad DSLR system accessory range.

Pentax X90 review
The Pentax X90 is an easy-to-use superzoom that offers decent picture quality and plenty of features. It's good value for money too, although it does feel rather plasticky.
