• While the back-side illuminated design helps with light gathering efficiency, physical limits on sensor area impact noise levels and dynamic range.
• Native ISO ranges from 100 to 12,800, but expect usable results mostly between 100-800 ISO due to noise at higher sensitivities.

Ricoh GR Sensor Analysis

• The GR features an APS-C sized CMOS sensor (23.7 x 15.7 mm), one of the standard sizes in enthusiast and professional cameras.
• 16 megapixels allow for excellent detail with a strong balance of resolution and noise performance.
• With a native ISO up to 25,600, the GR delivers solid low-light capability rarely matched by smaller sensor compacts.
• DxOMark rates the GR’s sensor with an overall score of 78, highlighting its excellent color depth (23.6 bits) and dynamic range (13.5 EV stops).

The Ricoh GR’s larger APS-C sensor outperforms the Pentax Q7’s smaller sensor in all key image quality metrics.

Real-World Impact

Your photos from the Ricoh GR will exhibit cleaner shadows, more detailed highlights, and less grain in challenging light. The Q7, despite its compact size, will introduce more noise and exhibit subdued dynamic range, noticeable in landscape and indoor low-light portraits.

Lens System and Optics: Flexibility vs Fixed Excellence

Lens technology directly impacts your creative control, image sharpness, and depth of field capabilities.

Pentax Q7 Lens Ecosystem

• The Q7 supports 8 native lenses, covering wide-angle to telephoto via the Pentax Q mount.
• The 4.8x crop factor means lenses behave differently than on APS-C or full frame; a 50mm lens acts like a ~240mm telephoto.
• This crop induces notable depth of field increase, making bokeh and shallow focus effects challenging, but manageable with fast lenses.
• Sensor-based image stabilization helps with sharp shots when handholding longer lenses or shooting macro subjects.

Ricoh GR Fixed Lens

• Equipped with a 28mm f/2.8 equivalent lens - a classic focal length for street, travel, and documentary photography.
• The lens shows stellar optical performance: sharp at f/2.8 with minimal distortion or chromatic aberration.
• Fixed aperture and focal length simplify operation and guarantee consistent image quality.
• Depth of field control at f/2.8 is moderate - less bokeh-heavy than wider apertures but provides excellent versatility.

Use-Case Reminder
