Pentax Optio M40 - Test shots - Full-res crops

A range of general test shots are shown over the next two pages. In some cases, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it to show the overall image quality. Some other pictures may be clicked to view the original full-size image.

Here's my usual detail test shot of the West Window of Exeter Cathedral, for you to compare with other cameras. See below for a full res crop, or click to see the whole picture.

The level of detail is about average for an 8MP camera, but contrast and sharpness could be better. The dull day didn't help though.

----



As with the M30, the lens produces a lot of barrel distortion at the wide angle end, as well as pincushion distortion at the telephoto end.

----



Centre sharpness isn't too bad, but I've seen better.

----



Corner sharpness is also rather poor.
