Panasonic Lumix DMC-TZ1 corner sharpness comparison
 |
To measure and compare the Panasonic Lumix TZ1's corner sharpness 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. We used the built-in lenses at their widest and longest focal lengths and with various apertures. Note the TZ1 only offers two apertures at each focal length, and selects them automatically; we forced it to use specific apertures by varying the brightness of our studio lights. The crops are taken from the extreme lower left corner of the chart and presented here at 100%. |
| Zoomed-out to wide angle, the Lumix TZ1 delivers reasonably sharp results in the corners, but zoom all the way in and the results become quite soft. This isn't surprising though for a lens with a 10x optical range that's squeezed into a compact body, and it's important to note the Fujifilm S9500 / S9000 with its considerably bigger optical system also suffers from softness when fully zoomed-in. Ultimately it's the price you normally pay for the convenience of a very long optical range. If you want pin sharp results in the extreme corners throughout the range, you normally have to go for a lens with a shorter optical zoom. There are exceptions though, such as the Panasonic FZ30, which delivers sharp corners throughout its optical range; again though, this is a larger camera, comparable in size to the Fujifilm S9500 / S9000. Note: crop details which appear smaller here are due to them being captured with lower resolution cameras and / or a lens which couldn't focus as close to the chart. In each case though, the crop still represents the extreme left corner of each camera's frame. |
