A Faster, Slimmer, More Responsive GR

Deemed "the ultimate snap shooter," the Ricoh GR IV is the latest installment in the popular compact fixed-lens camera series characterized by impressive image quality, a sharp prime lens, and supreme portability. This GR IV brings a new 25.7MP BSI CMOS sensor, redesigned 28mm-equivalent lens, improved AF and Shake Reduction, more built-in memory, a new battery, and updates to specialized focusing and shooting modes. Additionally, there is an all-new dedicated GR WORLD app for wireless settings control and image sharing.

New 25.7MP BSI CMOS Sensor and GR ENGINE 7

Featuring a new sensor and processor, the GR IV sports a 25.7MP APS-C CMOS sensor with a back-illuminated design for cleaner image quality and reduced noise.

This sensor pairs with the updated GR ENGINE 7 processor that helps to achieve a full stop better low-light performance along with a faster 0.6-sec startup time, quicker focusing performance, up to ISO 204800, and the same versatile 14-bit DNG and JPEG recording as its predecessor.

Faster and More Accurate Autofocus

One of the key upgrades of the GR IV is faster focusing performance. Aided by the new GR ENGINE 7 processing and a redesigned lens that's lighter in weight, AF performance is more responsive than its predecessor, focusing hunting is greatly reduced, and both face recognition and subject tracking have been improved. Additionally, pairing with the improved low-light image quality, low-light focusing is also faster and more accurate for shooting in difficult lighting conditions.

• During autofocus shooting, this AF system detects the subject's face or eye with precision, focuses on it, and indicates the in-focus position on the LCD display using the AF frame. When the camera detects multiple faces, it automatically distinguishes the main subject from secondary ones and indicates this on the focus frame.
• Full Press Snap function lets you override the AF in an instant by fully depressing the shutter button and having the lens immediately focus at a preset distance. This unique shooting and focusing function is perfect for street photography and eliminates any lag times for decisive moment-type shooting.

5-Axis Shake Reduction

One more asset for low-light use, the GR IV has a new 5-axis Shake Reduction system that compensates for up to 6 stops of camera shake. Improving upon the 3-axis system of the previous generation, this new stabilization system compensates for more types of camera movement and is more effective at reducing the appearance of camera shake when shooting handheld.

Image Control

• Image Control function offers 12 distinct modes to apply preset looks to a scene along with a new Cinema mode, with a choice of Yellow or Green tone, for a more nostalgic and filmic appearance.
• Saturation, contrast, hue, key, grain parameters of each mode can be adjusted to suit the desired effect and select settings also support strength and size tuning for an even more personalized look.
• User-selected settings can be added to the Image Control menu as a custom mode.
