Ricoh GR III vs Sony RX100 VA: A Thorough Large Sensor Compact Camera Comparison for Serious Photographers

When it comes to large sensor compact cameras, two models from 2018 stand out for their unique approaches: Ricoh’s GR III and Sony’s RX100 VA. Both are highly regarded among enthusiasts and professionals seeking a pocketable camera that can deliver excellent image quality without the bulk of DSLRs or mirrorless systems. But which one should you buy? To answer this, I tested both extensively across all major photography genres and use cases - from portraits to travel and everything in between.

In this detailed review, I’ll break down how these cameras stack up in real-world performance, image quality, handling, autofocus, lens characteristics, and value. Whether you’re a street shooter craving discretion, a landscape fan chasing dynamic range, or a professional needing a reliable backup, you’ll find targeted insights to help you choose wisely.

Let’s dive into the hands-on comparison.

Welcome to the Pocketable Giants: Understanding the Basics

At first glance, both the Ricoh GR III and Sony RX100 VA boast large sensors in compact bodies built for mobility without sacrificing quality.

• Ricoh GR III offers a fixed 28mm equivalent F2.8 lens with an APS-C sensor (23.5x15.6mm), ideal for street and documentary shooting.
• Sony RX100 VA features a versatile zoom lens from 24-70mm with a 1” (13.2x8.8mm) sensor, favoring flexibility and video performance.

Both have a 3” screen and support raw files, but diverge in autofocus systems, image stabilization, and video capabilities - areas this review will explore in depth.

First Impressions: Size and Handling

Both cameras are genuinely pocketable, but the Ricoh GR III is slightly slimmer and lighter at 257g compared to the RX100 VA’s 299g. The GR III’s minimalist design and dedicated manual control rings provide a tactile feel I found rewarding for fast shooting. In contrast, the Sony’s zoom lens adds thickness but offers reach and framing flexibility without sacrificing compactness.

Sensor and Image Quality: The Heart of the Matter

Image quality is often the deciding factor for enthusiasts and professionals alike. Here’s how these two cameras compare under the hood.

Ricoh GR III Sensor Tech and Results

• Sensor size: APS-C (23.5x15.6mm)
• Resolution: 24MP, no anti-aliasing filter
• Sensor type: CMOS

Ricoh uses a larger APS-C sensor - the same size found in many enthusiast mirrorless cameras - providing excellent control over depth of field and superior low-light performance. The absence of an optical low-pass (anti-alias) filter helps retain sharpness but risks artifacts at times.

What I experienced: Exceptional image quality with punchy colors and rich detail, especially in RAW, which the GR III’s sensor handles expertly. The larger sensor size means superior control over bokeh and skin tone rendition for portraits. High ISOs up to 102,400 are theoretically supported, but I found usable quality topping out around ISO 3200-6400 for clean results.

Sony RX100 VA Sensor Overview

• Sensor size: 1” (13.2x8.8mm)
• Resolution: 20MP
• Sensor type: BSI-CMOS, with anti-alias filter

Sony mounts a 1” sensor, smaller than APS-C but advanced with back-illuminated technology for improved light-gathering. The sensor offers excellent image quality in a compact form but naturally can’t match APS-C dynamic range or shallow depth-of-field control.

Real-world observations: The RX100 VA is spectacularly sharp in the center with smooth gradations, and the BSI design helps in low-light scenes. Noise management at high ISO is impressive but not quite at APS-C levels. The smaller sensor means less “creamy” bokeh but grants a longer zoom reach.

Lens and Focusing Systems: Precision vs Versatility

The fixed lens on the Ricoh GR III and the zoom lens on the Sony RX100 VA cater to very different approaches.

Lens Comparison

Ricoh’s GR III has a fast and sharp prime lens especially optimized for street and documentary photography. The F2.8 maximum aperture isn’t as fast as Sony’s but provides decent background blur given the sensor size.

The RX100 VA’s zoom lens is excellent optically, with a faster aperture at the wide end (F1.8), beneficial for portraits and low-light. The 24-70mm range really shines for travel, events, and everyday flexibility. Slight softness is present at telephoto 70mm but generally very good.

Autofocus Performance and Accuracy

Autofocus (AF) is critical for capturing fleeting moments accurately.

Ricoh GR III AF

• Hybrid AF: contrast detection + phase detection
• Touch-enabled AF points, face detection included
• No dedicated Eye-AF or animal detection

Ricoh’s AF system is surprisingly quick and accurate for a compact, but the lack of eye-detection makes portrait shooting slightly more challenging. In bright light, AF locks rapidly. In low light or complex scenes, it can struggle or hunt slightly.

Sony RX100 VA AF

• 315 AF points with hybrid phase-detection
• Eye AF available; sophisticated face tracking
• Fast autofocus, continuous AF for tracking moving subjects

Sony’s AF system outperforms the Ricoh significantly on moving subjects, face and eye tracking, and burst mode accuracy.

Burst Rates:

• Ricoh GR III: no specified burst speed
• Sony RX100 VA: Up to 24fps continuous shooting!

In wildlife or sports, the RX100 VA’s autofocus speed and burst capacity are decisive advantages.

Build Quality, Weather Sealing, and Ergonomics

Neither camera offers weather sealing, so take extra care in adverse conditions.

Physical Design and Control Layout

Ricoh employs a simple but effective control setup with dedicated exposure compensation dial and manual rings, which I appreciated during street photography - quick, tactile, and intuitive.

Sony’s RX100 VA has a tilting screen, great for low or high angle shooting, while the Ricoh’s is fixed and touch-enabled but non-tilting. The electronic viewfinder in the Sony is superior for bright light composition, offering 100% coverage and 2359k dots resolution, compared to Ricoh’s optional and optical-only VF (sold separately).

Genre-Specific Performance and Practical Use Cases

Now, let’s examine detailed real-world uses across photography genres, highlighting each model’s strengths.

Portrait Photography

• Ricoh GR III: Excellent skin tone rendering due to APS-C sensor, natural bokeh with pleasing background separation at 28mm. I found manual focus aids helpful for accuracy.

• Sony RX100 VA: Brighter lens at 24mm F1.8 enables beautiful subject isolation, especially in tight framing. Eye AF excels at locking focus quickly, a plus for portraits.

Winner: Tie. Ricoh’s sensor gives better image quality and shallower DOF; Sony’s zoom and AF system offer broader framing and focusing ease.

Landscape Photography

• Ricoh’s larger sensor offers superior dynamic range and sharpness, crucial to capturing rich landscapes.
• Sony’s zoom is versatile for composition but sensor size limits ultimate detail.

Winner: Ricoh GR III, especially when paired with tripod and low ISO techniques.

Wildlife Photography

• Sony RX100 VA dominates with rapid AF, 24fps burst, and telephoto reach (70mm equivalent).
• Ricoh not built for action, no burst mode.

Winner: Sony RX100 VA by a wide margin.

Sports Photography

• Again, Sony’s fast burst and reliable tracking AF make it the obvious choice.
• Ricoh’s slower AF and no continuous shooting hinder performance.

Street Photography

• Ricoh’s minimalist design, silent shutter, and prime lens make it a street favorite.
• Sony’s zoom adds some bulk but tilting screen and EVF are helpful.

Winner: Ricoh GR III for discretion and usability on the street.

Macro Photography

• Both cameras focus closely (5-6cm macro).
• Ricoh’s sensor-shift stabilization stands out for crisp close-ups.
• Sony’s optical IS helps at longer focal lengths.

Tie, depending on subject type.

Night / Astro Photography

• Ricoh’s APS-C sensor with sensor-shift IS lets you push ISO while preserving detail.
• Sony’s smaller sensor noise rises earlier, though optical IS helps.

Ricoh edges out for low-light quality.

Video Capabilities

Sony RX100 VA offers a clear advantage for video shooters with 4K recording and a tilting screen.

Battery Life and Storage

Sony claims 220 shots per charge; Ricoh’s official battery life was unspecified but typically around 200 shots.

Neither camera is stellar for extended shoots; carrying spare batteries recommended.

Both take SD cards (Ricoh supports UHS-I), and Sony also supports Memory Stick formats.

Connectivity and Wireless Features

• Ricoh GR III has built-in Wi-Fi but no Bluetooth or NFC.
• Sony RX100 VA adds NFC for simple smartphone pairing and an HDMI port for external monitors.
• Neither offers GPS.

Value and Pricing

Both cameras hold decent value for their specialties, but your choice should reflect your shooting priorities.
