IT168 Review Interchangeable lens portable computers are already deeply rooted in the hearts of the people, but Ricoh’s high-definition portable computers with interchangeable lenses and CCD components are undoubtedly unique among this type of products. Ricoh GXR has attracted a lot of attention since its inception, and those who like such a unique design are bound to be a group of slightly paranoid diehards. Those who dare to break through barriers and break conventions are the king of love for digital imaging. Ricoh launched a new P10 module in 2010. The module P10 has a 10-megapixel backlit CMOS sensor and a 28-800mm F3.5-5.6 V lens.
Trial evaluation of the new 10.7x optical zoom component Ricoh GXR+P10
The P10 lens device with 10.7x optical zoom capability has Ricoh’s independently developed shake correction system?VC?, and its lens The structure has a configuration of 10 elements in 7 groups, including 4 aspherical mirrors to ensure maximum control of axial chromatic aberration and spherical aberration. Backlit CMOS can take brighter and lower-noise photos in low-light environments.

Control details
Ricoh The GXR buttons and menu interface both demonstrate an excellent sense of professionalism. In addition to the manual M/A/S/P gears displayed on the mode dial, intelligent automatic party committee and scene modes are indispensable. In addition, we also see that three custom mode gears are set on the GXR, giving creativity and You who love manual work.

The three-way control button on the back of the fuselage makes menu control very efficient. It works together with the front dial to adjust the aperture, shutter and other functions. The project setup is very quick.

The level of Ricoh GXR also shows its professionalism In the settings, we can choose three different methods: display, sound, and display + sound to help us confirm the camera level.

Shooting mode
The scene mode of Ricoh GXR is very simple but very practical. The tilt correction mode can help us eliminate perspective oblique angles when shooting buildings from above or above, and obtain complete and realistic images.

Sharpness test
Ricoh GXR's P10 component has a 10-megapixel backlight CMOS. We will follow it to the ISO 100 sensitivity level and ISO 12233 resolution test target under uniform lighting to pay attention to its imaging resolution performance:

The performance of the P10 component with a high-magnification zoom lens design in the sharpness test allows us to see the details of the lens at the wide-angle and telephoto ends. The performance is balanced, and the dispersion at the edges is within the normal range. What is more worthy of recognition is that the image quality at the telephoto end has slightly declined.
Color test
The next step is the color test. When analyzing the imaging color of the test sample, we use the test sample to shoot the X-rite ColorChecker SG color test target at ISO 100 degrees, and then perform color analysis to obtain data such as imaging color error and white balance error. The white balance error value in the list is the color temperature error of the mid-gray block. The closer this value is to zero, the better. If this value is a positive number, it means that the imaging tone is cooler, and vice versa if it is a negative number. In the color error diagram, the squares in the Lab color gamut coordinates represent the ideal color (standard color) of the subject, and the circles represent the imaging color of the tested camera.
The following are the test images:

The color saturation of Ricoh GXR is quite high, and its color performance in the green area is impressive. We can easily take photos with vivid blue and green performance in the "Long View" mode of scene mode. The color and white balance show a slightly warmer trend.
"Noise test at each ISO level
The Ricoh GXR has sensitivity levels from ISO 100 to ISO 3200. Pay attention to its picture noise control at each sensitivity level. < /p>

We evaluate that the available ISO range of the P10 component of Ricoh GXR is below ISO 1600, and the performance is quite excellent. Next, we will further verify it from the screenshots of actual photos:

Lens quality test
For a 10.7x optical zoom lens, how do we compare the image quality at the wide-angle end and telephoto end? The following are the wide-angle and telephoto samples of Ricoh GXR+P10:
