Camera Unit – GR LENS A12 50 mm F2.5 MACRO

Newly developed 50 mm F2.5 ﬁxed-focal-length GR Lens

• A macro lens with high image quality made possiblethrough the

collective expertise of Ricoh optical technology.

• High resolution and high contrast to periphery.

• Rigorous elimination of image color fringing by reducing

magnication color aberration and frame-aberration color

differences.

• Successful distortion correction to a level where it is not necessary

to depend on electronic correction.

• With the aperture wide open, there is little vignetting and radiant

bokeh is achieved that maintains circle diameter to the edge

of the image.

APS-C size 12.3 million pixel CMOS sensor

• Perfect for portraits and macro photography. The best match for the

50 mm xed-focal-length lens; offers excellent bokeh characteristics.

3rd-generation imaging engine GR ENGINE III

• Installing an image processing engine inherited from the GR line,

we achieved higher speed by combining the engine with a

CMOS sensor.

What is a GR Lens?

To be a GR LENS, a lens must perform at or

above a level in its overall lens characteristics,

particularly with respect to MTF values,

distortion, and color aberration.
