Ricoh GXR P10 Review

Image Quality


All of the sample images in this Review were taken using the 10 megapixel Fine JPEG setting, which gives an average image size of 3.5Mb.

The Ricoh GXR P10 produced images of very good quality during the review period. The Ricoh GXR P10's main drawback in terms of image quality is noise, with ISO 400 showing some noise, blurring of detail and slight colour desaturation. The noise and loss of detail get progressively worse as you go from ISO 400 to 1600, although only the fastest setting of 3200 is not really worth using unless there's no other option.

The Ricoh GXR P10 handled chromatic aberrations very well with limited purple fringing effects appearing only in high contrast situations. The 10 megapixel images were just a little soft straight out of the camera at the default sharpen setting of Normal and either require some further sharpening in an application like Adobe Photoshop, or you should increase the built-in sharpening level. The night photograph was excellent, with the maximum shutter speed of 30 seconds allowing you to capture enough light for most situations.

The Dynamic Range mode works really well, resulting in images that have noticeably more dynamic range that those shot in the Normal mode. If you want to shoot images that retain detail in both the highlight and shadow areas, then the Ricoh GXR P10 unit is a great choice. There is one main drawback though; the DR images have noticeably less saturated colours than the Normal version, which more accurately matches the scene.

Macro performance is a stand-out highlight, allowing you to focus as close as 1cm away from the subject, although there is a lot of lens distortion and shadowing at such a close distance. The GXR P10's small built-in pop-up flash worked well indoors at full power, with no red-eye and good overall exposure, and the ability to fine-tune the power output is very welcome. The sensor-shift image stabilisation system is effective at reducing unwanted camera shake when hand-holding the camera.

Noise

There are 6 ISO settings available on the Ricoh GXR P10 camera unit. Here are some 100% crops which show the noise levels for each ISO setting for both JPEG and RAW files.

Focal Range

The Rioch P10 camera unit has a very versatile focal range that's equivalent to 28-300mm in 35mm terms.

Dynamic Range

When the Ricoh GXR P10 is in DR mode (Dynamic Range double shot) it takes two images with different exposures, and then records a single image that combines the properly exposed parts of each one. You can also choose to take a DR and Normal image at the same time (both are saved to the memory card). Here is an example which was shot with Normal and then the four DR modes (Very Weak, Weak, Medium and Strong).

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting of Normal. You can change the in-camera sharpening level to one of the preset levels if you don't like the default look.

File Quality

The Ricoh GXR P10 has 2 different image quality settings available, with Fine being the highest quality option. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.

Chromatic Aberrations

The Ricoh GXR P10 handled chromatic aberrations excellently during the review, with very limited purple fringing present around the edges of objects in certain high-contrast situations, as shown in the example below.

Example 1 (100% Crop)

Macro

The Ricoh GXR P10 offers a Macro setting that allows you to focus on a subject that is just 1cm away from the camera when the lens is set to wide-angle. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Flash

The flash settings on the Ricoh GXR P10 are Auto, Red-eye-Reduction, Flash On, Slow Synchro, Manual Flash, and Flash Off. These shots of a white coloured wall were taken at a distance of 1.5m with the 24-72mm camera unit.

Flash Off - Wide Angle (28mm)

Flash On - Wide Angle (28mm)

Flash Off - Wide Angle (300mm)

And here are some portrait shots. As you can see, neither the Flash On or the Red-eye-Reduction settings caused any red-eye.

Night

The Ricoh GXR P10's maximum shutter speed is 30 seconds, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 2 seconds at ISO 100. I've included a 100% crop of the image to show what the quality is like.

Anti Shake

The Ricoh GXR P10 has sensor-shift image stabilisation which allows you to take hand-held shots at slower shutter speeds than would otherwise be possible. The first shot was taken with anti shake turned off, the second with it turned on. Here are some 100% crops of the images to show the results. As you can see, with anti shake turned on, the images are much sharper than with anti shake turned off.
