Casio Exilim EX-Z850 Review

Review based on a production Casio Exilim EX-Z850

Announced just before PMA in February 2006 - almost exactly a year to the day after the camera it replaces - the EX-Z850 is Casio's latest ultra-compact flagship model, offering a huge feature set in a very slim, all-metal body. The EX-Z750 was very well received when it was launched, and remains to this day the most highly-specified 7MP ultra-compact on the market. The EX-Z850 doesn't change the basic formula much but does offer a raft of small improvements; there's an extra megapixel, a couple new Best Shot modes, improved screen brightness, a more powerful flash (with some extra modes) and a movie light. As is becoming standard on this type of camera the Z850 also includes a 'high sensitivity' mode, with up to ISO 1600 on offer.

If you're new to digital photography you may wish to read the Digital Photography Glossary before diving into this article (it may help you understand some of the terms used).

Conclusion / Recommendation / Ratings are based on the opinion of the reviewer, you should read the ENTIRE review before coming to your own conclusions.

Images which can be viewed at a larger size have a small magnifying glass icon in the bottom right corner of the image, clicking on the image will display a larger (typically VGA) image in a new window.

To navigate the review simply use the next / previous page buttons, to jump to a particular section either pick the section from the drop down or select it from the navigation bar at the top.

DPReview calibrate their monitors using Color Vision OptiCal at the (fairly well accepted) PC normal gamma 2.2, this means that on our monitors we can make out the difference between all of the (computer generated) grayscale blocks below. We recommend to make the most of this review you should be able to see the difference (at least) between X,Y and Z and ideally A,B and C.
