Sony RX1 vs RX1R II: An Expert’s Take on Two Pioneering Full-Frame Compacts

Sony’s RX1 series has carved a legendary niche among photography enthusiasts craving uncompromised full-frame image quality in a pocketable package. From the original RX1’s arrival in 2013 - a trailblazer with its fixed 35mm F2 lens and full-frame sensor - the line has evolved thoughtfully, leading to the RX1R II in 2015, which refined and boosted just about every key spec. But does the RX1R II’s advancements justify its nearly $500 premium? More importantly, which camera fits your creative style and workflow?

Having practically lived with both cameras - and measured their merits across genres from portraiture to astrophotography - I’m here to unpack the practical performance, technical details, and real-world usability. Let’s get into the nitty-gritty.

A Tale of Two Titans: Sony RX1 and RX1R II Overview

Before diving depth-first, a snapshot of what separates these two siblings helps put things in context.

The original Sony RX1 shook up the market with a 24MP full-frame sensor, a fixed 35mm F2 Zeiss Sonnar lens, and a compact body barely larger than many mid-range compacts. It championed image quality over all else, yet lacked in some modern niceties such as a viewfinder and cutting-edge autofocus.

The RX1R II took things several steps further: a 42MP BSI-CMOS sensor (nearly doubling resolution), a tilting 3-inch LCD, an integrated high-resolution electronic viewfinder, improved autofocus system including phase detection, and an updated processor.

Both share that hallmark Zeiss 35mm F2 lens and large sensor goodness, but the RX1R II definitely pushes the envelope.

Look closely at that size comparison - physically very close in footprint (about 113x65x70mm vs. 113x65x72mm), the RX1R II adds a bit of heft (507g vs. 482g) but gains a tilting screen and a built-in EVF, which you’ll find invaluable outdoors.

Sensor and Image Quality: Pixels, Pixels, Pixels... and Then Some

This is the beating heart of any camera debate - how does sensor tech translate into photos in the wild?

The Sony RX1 sports a 24MP full-frame CMOS sensor with an anti-alias filter, offering a resolution maxing out at 6000x4000 pixels. It’s a traditional design optimized for excellent dynamic range and color depth. DxO marks it a very solid 93 overall, with a color depth of 25.1 bits and an impressive dynamic range (14.3 EV). ISO performance is good, with usable images extending beyond ISO 2500.

The RX1R II upgrades the sensor to a 42MP back-illuminated CMOS (BSI-CMOS) - that’s a substantial jump to 7952x5304 max resolution, and it foregoes the anti-alias filter entirely, aiming for maximum sharpness and detail. DxO scores it even higher at 97 overall, capturing a bit more color accuracy (25.8 bits), although dynamic range drops slightly to 13.9 EV - a minor trade-off, but something to note for high-contrast scenes. Its low-light ISO performance improves, pushing a practical limit to 3204 ISO.

Hands-on testing confirms these numbers: the RX1R II produces astonishingly crisp images - at base ISO, details explode with microcontrast and texture impossible to match with the 24MP RX1 sensor. However, this compressed dynamic range means that highlights clip earlier, so careful exposure or HDR bracketing can be vital in very contrasty landscapes.

For shooters prioritizing ultimate detail - commercial, landscape, or fine art photographers - the RX1R II’s sensor is a dream. But if you routinely need to pull maximum shadow and highlight detail, the original RX1’s slightly larger dynamic range might influence your choice.

Autofocus and Manual Focus: Old School or New School?

Autofocus can make or break shooting fast-moving subjects and rarely impresses on these compact full-frame models - but what do these two deliver?

The Sony RX1 relies exclusively on contrast-detection autofocus with 25 focus points geared around a center-weighted system. There’s no continuous AF, but it offers face detection. It’s a methodical and accurate AF - albeit slow compared to modern mirrorless AF systems. Manual focusing with focus peaking is well-supported, although somewhat fiddly on the fixed lens.

The RX1R II significantly upgrades with hybrid AF, combining phase detection and contrast detection over the same 25 points, enabling more reliable and faster autofocus, especially for single point AF-S mode. Face detection is retained, but animal eye AF is missing (a minor gripe in 2015, a real downside now). Still, the RX1R II visibly nails focus faster and with more confidence in trickier lighting or on moving subjects. Manual focus benefits from enhanced magnification and a tilting screen - a real aid for macro-like close focusing down to 14cm (vs. no macro range on the RX1).

In wildlife or sports photography, the RX1R II’s hybrid system will win you critical shots you’d lose with the original’s slower contrast system. But for street or landscape photographers who like to pre-focus or prioritize precision, both cameras’ excellent manual focus support and peaking remain strong.

Handling, Ergonomics, and Controls: Marrying Compactness with Usability

Enjoying the shooting experience depends hugely on how the camera feels in your hands and how intuitive controls are - especially given these are high-res full-frame cameras sold as ultraportables.

Both cameras share a similar, minimalist control layout with well-positioned dials and buttons, but the RX1R II edges ahead with a customizable function button and an intuitive lock switch on the mode dial (super handy to avoid accidental changes during shooting).

The addition of a high-resolution electronic viewfinder (0.74x magnification, 100% coverage) on the RX1R II feels transformative. It neatly solves bright-light visibility problems that plagued the RX1, which offered only an optional optical EVF - an accessory most users didn’t spring for due to size and price.

Though neither camera sports a touchscreen, the RX1R II’s tilting screen is a godsend for low-angle or overhead shooting (landscape and macro, I’m looking at you).

One quirky thing I’ve noticed: the RX1’s fixed screen is clear and bright but feels less flexible; in tight street or travel shots, the RX1R II’s articulating screen lets you be way more discreet with composition.

Lens and Optical Performance: The 35mm Zeiss Standard Bearer

Both cameras house the same fixed 35mm F2 Zeiss Sonnar lens - one of their biggest selling points. This lens delivers razor-sharp imagery with stellar corner-to-corner sharpness even wide open, excellent microcontrast, and fantastic bokeh.

The lens is well suited for environmental portraits, street photography, and documentary-style shooting.

The RX1R II lens’s coating seems modestly improved, reducing flare nicely in harsh backlight (evident on outdoor shoots).

Macro lovers, though, will find the RX1R II’s minimum focusing distance of about 14cm lets you get closer to subjects - a big plus missing from the original.

Build Quality & Environmental Durability: Tough Enough for the Road?

Neither camera is weather sealed or ruggedized - not surprising given their compact priorities. Both feature robust magnesium alloy bodies, but with delicate electronics beneath a stylish exterior. Neither will survive much more than light rain or dust without a protective housing.

If you’re often shooting in harsh or unpredictable environments, it’s worth noting that while these cameras don’t claim environmental sealing, their solid construction and sealed buttons mitigate minor weather exposure - but don’t push your luck.

Video: Squeezing More from a Still Camera

Video remains secondary on both models but the RX1R II steps up slightly with more flexible recording options.

Sony RX1 offers full HD 1080p video at 60, 50, 25, and 24fps with MPEG-4 and AVCHD formats. It supports an external mic but no headphone jack, making audio monitoring awkward.

RX1R II also caps at 1080p (no 4K unfortunately), but adds 120fps slow-motion in 720p, new XAVC S codec support (higher bitrates = better quality), and built-in Wi-Fi for remote control and wireless file transfer. Again, external mic supported but no headphone jack.

For video professionals or hybrids, neither camera is a go-to. But casual b-roll shooters will appreciate the RX1R II’s marginal enhancements and wireless app control.

Battery Life and Connectivity: When and How You Shoot Matters

Expect limited battery longevity from these compact beasts. The RX1 delivers around 270 shots per charge, while the RX1R II drops slightly to 220 - likely due to the power-hungry high-res sensor and EVF. In practical terms, bringing a spare battery is non-negotiable for serious shooting days.

Connectivity-wise, the RX1 relies on Eye-Fi card compatibility for wireless, which today feels dated and clunky. The RX1R II features built-in Wi-Fi and NFC, offering smoother smartphone integration and faster image sharing - a boon on travel or street shoots.

Both cameras store images on SD/SDHC/SDXC cards but with slightly differing memory stick compatibility.

Real-World Performance Across Photography Genres

How do these specs translate to your shooting style? Allow me to share pros and cons by genre:

Portrait Photography

Thanks to the Zeiss 35mm F2 lens’s creamy bokeh and gorgeous rendition of skin tones, both cameras excel here. The RX1R II’s higher resolution lets you capture exquisite detail in eyes, hair, and fabric texture - perfect for studio or environmental portraits.

Autofocus performance, while improved in the RX1R II, still requires patient focusing, making manual focus critical for perfectionists. Its face detection is solid but not game-changing.

Landscape Photography

Dynamic range is king here. The RX1’s slightly superior 14.3 EV dynamic range edges out the RX1R II’s by about half an EV, helping preserve highlights and shadows in complex landscapes. That said, the RX1R II’s resolution blowout (42MP) allows for more cropping and gigantic prints.

Weather sealing is absent on both, so caution is needed shooting in wet or dusty conditions.

Wildlife and Sports Photography

Here, autofocus speed and burst capability matter most. Neither camera is designed as a sports specialist (5 fps burst, slow AF), but the RX1R II’s hybrid AF delivers better lock-on and quicker focus acquisition. Still, pros shooting fast action will prefer dedicated APS-C or full-frame mirrorless sports cameras.

For telephoto needs, these fixed-lens 35mm cameras rely on cropping or pairing with digital teleconverters, sacrificing image quality at long distance. Not ideal for wildlife close-ups.

Street and Travel Photography

Compact size, discreet design, and rich image quality are key. Both shine, especially given their full-frame sensors. The RX1R II’s tilting screen and EVF help in bright daylight and tricky angles.

RX1’s better battery life might matter for long travel days, but wireless connectivity on the RX1R II adds convenience.

Macro Photography

The RX1R II’s ability to focus at 14cm makes it viable for some macro, although the fixed 35mm lens limits magnification - still, very usable for close-up product or nature shots.

The original RX1 lacks macro range - making it less appealing for detail-oriented close-ups.

Night and Astro Photography

High ISO performance favors the RX1R II, with cleaner images past ISO 3200. The lack of stabilization in both cameras means steady hands or tripods are essential. Long exposures are well supported.

Professional Use and Workflow Integration

Both cameras shoot uncompressed RAW - a godsend for pro post-processing. The RX1R II’s higher resolution is a clear asset for client work requiring large prints or heavy cropping.

Lack of rugged sealing and modest battery life limits these for field-heavy pros, but for studio and street pros demanding absolute image quality in a compact system, both are viable.

Which One Should You Buy? Recommendations Tailored to Your Needs

Within the premium large sensor compact niche, the RX1 and RX1R II stand near the top for their unique blend of quality and size.
