Ricoh GR III vs Sony RX100 VII: Ultimate Large Sensor Compact Camera Showdown

When it comes to compact cameras boasting large sensors, the Ricoh GR III and Sony RX100 VII are titans catering to serious photographers who demand quality, versatility, and portability. But how do these two precise instruments really stack up in the trenches of real-world use? After extensive hands-on testing, analyzing specs, and comparing performance across multiple photography disciplines, this comprehensive comparison distills what you need to know before investing in either of these compact powerhouses.

Gripping the Cameras: Size, Build, and Usability

The first tactile impression is often the lasting one. The Ricoh GR III opts for a minimalist, sleek body designed with street and travel photography in mind - it’s incredibly compact, almost unobtrusive, measuring 109 x 62 x 33 mm and weighing 257 grams. The Sony RX100 VII, by comparison, while still compact, is slightly larger at 102 x 58 x 43 mm and heavier (302 grams), reflecting its extended 24-200mm zoom lens and more complex internals.

Both cameras lack environmental sealing, so they require some care in harsh weather. However, build quality is solid on both fronts, with the GR III’s magnesium alloy body feeling robust despite its featherweight frame. The RX100 VII feels more substantial in hand, with a pop-up electronic viewfinder that adds bulk but also raises utility.

Ergonomics wise, the GR III embraces simplicity with its fixed 28mm f/2.8 lens and fewer controls, encouraging a fast, decisive shooting style. The RX100 VII’s top plate buttons, dials, and tilting screen (more on that shortly) give more hands-on control and menu access but with a steeper learning curve.

Sensor Details and Image Quality – The Heart of the Matter

The core difference here lies in sensor size and resolution. The Ricoh GR III sports a 24MP APS-C CMOS sensor measuring 23.5 x 15.6 mm (approximately 367 mm² sensor area) with no anti-aliasing filter - a design choice that prioritizes sharpness and micro-detail. The Sony RX100 VII uses a 20MP 1-inch BSI-CMOS sensor (13.2 x 8.8 mm, ~116 mm² area) with an anti-aliasing filter, helping reduce moiré but a slight trade-off in ultimate resolution.

Both sensors are modern, backside-illuminated units offering excellent image quality in their class. Though the RX100 VII has a slight edge in dynamic range (~12.4 EV tested by DxOMark) and offers superior high ISO noise handling (low light ISO score ~418), the GR III’s larger sensor gives it noticeable advantages in depth of field control and tonality, especially under good lighting.

For example, in portraits, the GR III’s APS-C sensor delivers richer skin tone gradations and smoother color transitions. The fixed 28mm lens - equivalent to ~42mm full-frame - provides a natural perspective, although the f/2.8 maximum aperture limits shallow depth of field artistry compared to some faster lenses.

The RX100 VII’s zoom versatility between 24 to 200mm (full-frame equivalent 24–200mm) is impressive, rivaling even many mirrorless cameras' lens ranges, offering everything from wide angles to telephoto for wildlife or sports - but its smaller sensor area moderates the bokeh quality and low-light performance somewhat.

Display and Viewfinder: Framing Your Shot

Both cameras feature 3-inch LCDs, yet they differ in design and resolution. Ricoh’s GR III has a fixed 1037k-dot touchscreen, crisp and responsive but lacking tilt or swivel. This can limit comfort when shooting from unusual angles.

The Sony RX100 VII sports a versatile tilting 3-inch screen at 921k dots with touchscreen support, much appreciated in vlogging or macro work where low and high-angle shots matter. Moreover, Sony includes a high-resolution (2.36M dots) pop-up electronic viewfinder covering 100% of the frame with 0.59x magnification, a significant advantage for bright conditions or precise composition.

In my testing, the RX100 VII’s viewfinder greatly improved eye-level shooting accuracy, especially under strong sun glare where the GR III’s absence of an EVF made composition more challenging.

Autofocus Systems: Speed Meets Accuracy

Autofocus technology lies at the core of each camera’s appeal, and their approaches reflect their design philosophies.

Ricoh’s GR III employs a hybrid AF system combining contrast-detection and phase-detection focus points. While generally reliable, it can occasionally hesitate in low-contrast scenarios or fail to lock instantly on fast-moving subjects. It supports face detection and touch AF, but lacks animal eye detection.

Sony’s RX100 VII excels with a sophisticated 357-point phase-detection autofocus system, augmented by 425 contrast-detection points, delivering rapid, near-instant focus lock even in demanding conditions. Crucially, it supports real-time eye AF for humans and animals - a feature remarkable for a compact - making it profoundly reliable when shooting wildlife or portraits with moving subjects.

This difference was stark in sports and wildlife testing. The RX100 VII tracked erratic movement with greater consistency, while the GR III required more deliberate focusing and patience.

Burst Rates and Buffer Performance

For action shooters, continuous shooting speed and buffer capacity are critical.

The GR III lacks official continuous shooting specs in our tested data, which hints at its limited framing rate - underscoring that it’s not tailored for bursts or fast-action imaging.

The RX100 VII shines here with a blazing 20 frames per second burst shooting speed (albeit with autofocus locked on the first frame), excellent for capturing split-second moments in sports or wildlife. This is a substantial advantage for users whose work or hobby demands fast reflexes.

Lens and Magnification: Fixed Simplicity or Zoom Versatility?

The GR III’s fixed 28mm f/2.8 lens is its signature strength and limitation. Delivering spectacular image quality with sharpness edge to edge, it’s a favorite for street, documentary, and travel photographers who embrace a “one lens, one perspective” philosophy. The fast f/2.8 aperture enables usable low light and some subject separation, complemented by a reliable sensor-shift stabilization system.

The RX100 VII’s 24-200mm f/2.8-4.5 zoom lens offers vast framing flexibility - from wide environmental landscapes to distant wildlife and portraits compressed at longer focal lengths. Though its maximum aperture narrows at telephoto end (f/4.5), the combination of optical image stabilization and excellent autofocus helps maximize sharpness.

For macro lovers, the GR III’s minimum macro distance is short at 6cm, delivering excellent detail for close ups. The RX100 VII’s macro at 8cm is respectable though slightly longer, limiting extreme magnification.

Portability and Travel Friendliness

On the road with a camera, every gram and centimeter counts. The GR III’s svelte frame slips discreetly into almost any pocket or bag, making it an ideal travel companion for photographers who prioritize stealth and ease.

The RX100 VII, larger and bulkier due to its zoom mechanism and EVF, still fits into coat pockets and compact packs but is less stealthy. However, its zoom range vastly increases creative options without changing lenses - a boon while traveling light.

Battery life is solid but not class-leading for either: Ricoh rating data is sparse, while Sony’s RX100 VII delivers approx. 260 shots per charge - adequate for casual use but best supplemented with spares on extended outings.

Video Capabilities: Beyond Stills

The Ricoh GR III supports Full HD 1080p video up to 60 fps, recorded in MOV format. It’s competent for casual video but lacks advanced features like 4K, external microphone input, or in-body stabilization adjustments specific to video workflows.

Contrastingly, the RX100 VII offers 4K UHD video at 30p using the XAVC S codec with no pixel binning, delivering superior clarity and detail. It features optical steady shot stabilization for smoother handheld footage, a microphone input port for professional audio, and supports slow-motion recording. This combination makes the Sony much more compelling for hybrid shooters seeking high-quality video alongside impressive stills performance.
