The subject may not realize the photo has already been taken. With the GR DIGITAL, that is the kind of quick shooting you will find paired with superb image quality.
The new 28 mm/F1.9 lens features outstanding brightness.
A convergence of sophisticated image processing capabilities and comprehensive shooting functions: GR DIGITAL III.
Sparking an explosion of photographer creativity, a new legend is born.

As photography lovers themselves, the developers focused all their passion and creative vision on the creation of a new lens of unprecedented power: the 28 mm/F1.9 GR Lens. If image quality is the priority, set a lower-than-ever ISO sensitivity. If capturing a shutter chance is the priority, set a higher-than-ever shutter speed. F1.9 expands the freedom and scope of your photographic expression.

So how was this lens able to control the various types of aberrations that increase as the aperture increases? While maintaining a basic configuration optimized for thin storage, frame aberration was reduced by adding two elements in one group to the rear. In addition, three special low-dispersion lenses were used to achieve high resolution and contrast while minimizing color aberration. The use of two high-precision aspherical lenses made distortion almost unnoticeable. In order to create this ultra-high-precision and high-performance lens, highly precise manufacturing processes and an exclusive control system were newly developed. It was dedication and tenacity that gave birth to this jewel of a lens.

Ghosting is one of the causes of image quality deterioration. To eliminate the problem, all of the individual lenses that are part of the GR Lens have been covered with the multi-coating optimum for each. To minimize the small residual reflection striking the CCD, we also ran original simulations repeatedly to determine optimum conditions for lens curvature, etc. As a result, we successfully suppressed ghosting, particularly that caused by off-screen light sources such as the sun.
