Sample Photos
In the following sample images, clicking on the larger image will download the full resolution original. Each photo is accompanied by four actual-size crops.
| Landscape Sample | ||||
|---|---|---|---|---|
 |
Focal length: 18mm This shot was taken in aperture priority mode, with multisegment metering and spot autofocus, using the Landscape custom image setting. At the lens’ widest angle and a middling aperture setting, we see a reasonable level of sharpness, no problem with chromatic aberration and an attractive color rendition. |

 |
|
| Building Sample | ||||
|---|---|---|---|---|
 |
Focal length: 31mm
Aperture: f/7.1 Taken using multisegment metering in program mode, using the Bright custom image setting, this shot of a richly textured building reveals very good detail retention in both the bright and shadowed areas. |
|||
 |
 |
 |
 |
|
| Low Light Samples | |
|---|---|
 |
Focal length: 50mm
Aperture: f/7.1 This scrimshaw knife was shot in low light with the Bright custom image setting (which uses a modest amount of sharpening) in shutter priority mode, using each of the high ISO noise reduction settings. after taking a manual white balance reading. The good news: ramping up the level of noise reduction processing doesn’t hurt image detail much. The bad news: there’s still a fairly high level of noise even at the highest setting. |
 |
|
 |
|
 |
|
 |
|
| High Dynamic Range Sample | |
|---|---|
 |
Focal length: 37mm
Aperture: f/4.5 Shot in program mode with multisegment metering, using the Bright custom image setting and a sturdy tripod. The photo at left was taken without HDR, the next two were taken with high dynamic range set to levels 1 and 2. We like the dynamic range expansion, but as seen in the same-size captures at the bottom, camera movement mars the sharpness of the HDR images, and the self-timer is unavailable to minimize shake. |
