Specification :
Over a history of nearly three decades (since the introduction of the film camera, RICOH GR1 in 1996), and two decades (since the introduction of the first digital-format GR DIGITAL in 2005), the GR series has always kept the basic concept of pursuing the essential values of a camera: high image quality, quick response and portability. At the same time, the series has always incorporated the changes and refinements demanded to meet emerging user needs. Because of this, GR-series models have been preferred by many photographers, particularly professionals and highly experienced amateurs.
Currently under development, the RICOH GR IV inherits the basic GR-series concept, while also incorporating totally new components, including a newly designed lens, a new image sensor and a new imaging engine, to further upgrade image quality. It also features more advanced communications functions and is compatible with a new application designed for smart devices to improve operability and functionality.
Based on this new GR IV, another GR-series model featuring an HDF (Highlight Diffusion Filter) is also under development.
Designed to be the ultimate snapshot camera in the history of the GR series, the RICOH GR IV is a totally new breed of camera, one which will satisfy every photographer’s demands and expectations.
