Pentax Optio Z10 resolution comparison
| |
To measure and compare the Pentax Optio Z10's resolving power we photographed the Enhanced Digital Camera
Resolution Chart with it and a number of rival compacts, each using their
best quality JPEG and default image tone and sharpening settings. Each camera was tested at every aperture setting and the best result selected for this page.
The crops are taken from the original images, saved as High Quality JPEGs
in Photoshop CS2 and presented here at 100%. Each number represents 100
lines per picture height (lpph), so a figure of 20 means a resolution of
2000 lpph. In terms of studio resolving power, the Pentax Optio Z10 delivered 1550 lpph of horizontal and vertical resolution, which is below average for an 8 Megapixel compact. Both the Canon 860 IS / SD870 and Panasonic FX33 have 8 Megapixel sensors and delivered a far better result here - we've also included a result from the Sony W200 to show how a 12 Megapixel compact compares in this respect.
So it's a disappointing result here for the Z10, but as always it's important to evaluate other results for the complete picture. So now let's look at how it handles different sensitivities in our Pentax Z10 noise results page. |
