Panasonic Lumix DMC-TZ1 resolution comparison
 |
To measure and compare the Panasonic Lumix TZ1's resolving power we photographed the Enhanced Digital Camera
Resolution Chart with it and a number of rival models, each using their
best quality JPEG and default image tone and sharpening settings. 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 horizontal resolution, the Panasonic Lumix TZ1 performs similarly to the Fujifilm F11 and Canon PowerShot A620, despite each having higher resolution 6 and 7 Megapixel sensors respectively. In terms of vertical resolution though, these higher resolution sensors allow both cameras to out-resolve the Panasonic TZ1, although if you compare the results with those from our earlier Compact Digital Camera Group Test, the TZ1 still out-resolves the Pentax Optio S6 despite having a lower resolution. Note the TZ1 aperture cannot be set manually, so we adjusted our lighting to force it to switch between its two aperture settings at the test focal length: f3.8 and f6.3; the former resolved noticeably more detail on the chart, so has been used on this page. We also reshot the latest test chart with the Fujifilm FinePix S9500 / S9000 at all apertures and found f5.6 to resolve the most detail, so the results here are taken at that setting. Here the Fujifilm S9500 / S9000 with its larger lens and 9 Megapixel sensor unsurprisingly resolves the greatest detail, but it's also important to see how this influences real-life results - see previous page. |
