Leica X2 vs Sony RX1R II: A Hands-On Comparison of Two Compact Large-Sensor Cameras

When it comes to compact cameras packing large sensors and fixed prime lenses, there’s a special allure. They bridge the portability of smaller cameras with the image quality closer to DSLRs and mirrorless systems. But not all compacts with big sensors are created equal, and over my 15 years of hands-on testing, I’ve seen how nuances in sensor technology, optics, and ergonomics dramatically shape the shooting experience. Today, we’re diving deep into two significant players from different eras and pedigrees: the Leica X2 and Sony’s Cyber-shot DSC-RX1R II.

I’ll walk you through the major technical and real-world performance differences, with practical insights geared for serious enthusiasts and pros alike - no fluff or marketing jargon, just established facts from exhaustive testing and side-by-side comparisons. If you want to understand which camera deserves a spot in your bag or studio, you’re in the right place.

First Impressions: Design, Handling, and Build Quality

Handling is more than just a subjective feel – it directly impacts your shooting efficiency and the joy of photography. The Leica X2, announced in 2012, is beautifully hand-built with that vintage Leica DNA: a compact but solid magnesium alloy body measuring 124x69x52mm and weighing a svelte 345 grams. Its small footprint and minimalist design make it highly pocketable, although the ergonomics are best suited for photographers with a preference for hold-it-and-shoot simplicity. The lack of weather sealing and a fixed non-tilting screen signal its construction dates back several years.

In contrast, the Sony RX1R II, released in 2015, ups the ante with a slightly larger and heavier build at 113x65x72mm and 507 grams. The added heft doesn’t feel cumbersome, thanks to a well thought out grip and control arrangement. Notice the difference below in the top control layout, where Sony offers more buttons and dials for quick access - a boon for rapid-fire shooting and manual tweaking.

The RX1R II also includes a tilting 3-inch LCD and one of the best built-in electronic viewfinders (EVF) I’ve tested in a compact, boasting 2.36 million dots with 100% coverage and .74x magnification. The Leica, meanwhile, sticks to a fixed 2.7-inch screen without touchscreen capabilities and offers an optional external EVF accessory - a more niche setup.

While neither camera offers environmental sealing, you’ll find both bodies built with premium materials. However, if you expect ruggedness or weather resistance for outdoor extremes, neither is ideal without additional protection.

Sensor Technology and Image Quality: APS-C Versus Full Frame

At the heart of any camera is the sensor, and here is where the two diverge significantly. The Leica X2 sports a 16MP APS-C CMOS sensor sized 23.6x15.8mm, reminiscent of sensors popular in mid-level mirrorless cameras a decade ago. The Sony RX1R II features a 42MP full-frame back-illuminated (BSI) CMOS sensor measuring 35.9x24mm.

What does this mean in practice? First, full frame sensors typically deliver superior dynamic range, better noise control, and shallower depth of field compared to APS-C. The Sony’s sensor embodies this with a DxOMark sensor rating of 97 overall, 25.8 for color depth, 13.9 stops dynamic range, and impressive low-light ISO sensitivity rated at 3204. In contrast, while Leica's sensor has not been formally tested by DxOMark, it's known to perform well for an APS-C sensor of its generation with solid color reproduction but less dynamic range and higher noise at elevated ISO settings.

Further, the RX1R II lacks an anti-aliasing filter, which increases sharpness at the risk of moiré artifacts. Leica X2 maintains a standard AA filter for smoother rendering but slightly less microdetail.

When shooting landscapes or studio portraits demanding utmost resolution and tonality, the RX1R II’s 42-megapixel sensor offers a remarkable leap forward over the X2’s 16. On the other hand, the Leica's simpler 16MP count can still produce excellent prints at moderate sizes and benefits from files that are easier to handle on modest CPU setups.

Lens and Optical Characteristics: Fixed Focal Lengths With Distinct Styles

Both cameras feature fixed prime lenses tailored to different philosophies. Leica's X2 comes equipped with a 36mm equivalent lens (f/2.8 max aperture), while Sony RX1R II packs a classic 35mm f/2 Zeiss Sonnar lens. On paper, focal length is similar, hovering around the classic street and reportage staple of 35mm, but the optical design and aperture range make a sizable difference.

The Leica’s f/2.8 aperture is respectable but not blazing fast, which means in lower light situations you’ll have to bump ISO or slow shutter speeds compared to the Sony’s brighter f/2 lens. Its optical design strikes a balance between sharpness and compactness with minimal distortion, but it won’t produce the creamy bokeh effects that photographers seek for portraits.

Sony’s Zeiss lens is flagship level: very sharp wide open, with excellent contrast and microcontrast, and delivers a more pleasing falloff in the out of focus areas (bokeh). The lens allows for close focusing down to 14cm, whereas Leica’s macro reach starts at 30cm - a limitation if you want to explore detailed macro work.

This difference becomes critical depending on your primary subjects. Portrait photographers will appreciate the RX1R II’s aperture and focusing closer to the subject for stronger subject isolation. For street or travel use, the Leica’s slightly longer equivalent focal length at 36mm offers a marginally tighter frame, which some might prefer for discreet candid captures.

Autofocus Performance: Speed Versus Precision

Autofocus is an often-underestimated factor that can make or break your shooting flow. The Leica X2 employs contrast-detection AF with 11 focus points but no continuous AF or tracking - quite basic by modern standards. Face detection is present but not very reliable in challenging light.

Sony RX1R II uses a hybrid autofocus system combining contrast and phase detection with 25 AF points, face detection, and continuous AF tracking. From my repeated tests, the RX1R II’s AF is notably faster and more accurate, especially in low-light and moving subjects, though it still doesn't reach the blazing speeds of some premium mirrorless bodies.

For wildlife and sports photographers, neither camera is ideal given the single-shot AF and moderate 5 FPS burst shooting in both cameras. However, if you want a compact with some degree of tracking, the RX1R II is the better choice.

User Interface, Controls, and Screen

The Leica X2’s interface is minimalistic with only essential physical controls and a small fixed LCD. While that simplicity appeals to purists who prefer manual exposure control without distraction, it does limit on-the-fly adjustments. Unfortunately, no touchscreen means cursor navigation can feel slow.

Sony RX1R II offers a more evolved user interface with a tiltable 3-inch high-res LCD and an intuitive menu system consistent with Sony’s Alpha bodies. Though it still lacks touch support, you can customize many buttons for quicker access to your favorite settings, greatly enhancing efficiency in the field.

If you’re using manual focus, the RX1R II also provides focus peaking assistance and a micro-zoom feature to nail critical sharpness - not available on the X2.

Image Stabilization and Low-Light Shooting

Neither the Leica X2 nor Sony RX1R II incorporate in-body image stabilization (IBIS), relying entirely on their optics to compensate. This is a significant factor if you often work hand-held in dim environments or want to shoot video (which we’ll discuss soon).

Low-light shooting is easier in the Sony, thanks to the full-frame sensor’s better high-ISO performance and the faster f/2 lens. The Leica’s APS-C sensor and f/2.8 lens combination mean you’ll likely bump ISO to levels that start degrading image quality more quickly.

Video Capabilities: Static Shooters vs Multimedia Creators

If video is a consideration - and many photographers now expect hybrid capabilities - there’s a clear winner: the Sony RX1R II.

Leica X2 does not offer video recording, emphasizing its role as a pure stills camera. Those invested in classic photography processes or prioritizing image quality above all will see this as a plus or a non-issue.

Sony RX1R II shoots full HD video (1920x1080) up to 60p with multiple codecs including XAVC S and AVCHD. It also supports 120fps slow motion in 720p. Audio input options include a microphone port, which is rare for compacts and allows for better sound capture. However, there’s no headphone jack for monitoring sound live during recording.

Neither camera features in-body stabilization - so handheld video will require steady hands or a gimbal for smooth footage. Nonetheless, RX1R II’s video specs cater well to photographers expanding into multimedia storytelling at a professional level.

Battery Life, Storage, and Connectivity

Battery life is a noteworthy difference for those planning day-long shoots. Leica’s X2 can capture roughly 450 shots per charge - solid for a compact but typical of its time. The Sony RX1R II’s powerful sensor and EVF drain batteries faster, clocking in around 220 shots per charge. I always recommend carrying spare batteries when using the RX1R II on extended outings.

Both cameras support SD memory cards, but Sony also handles SDXC and Memory Stick Pro Duo cards, affording flexibility for users invested in Sony’s ecosystem.

Connectivity-wise, the RX1R II is ahead with built-in Wi-Fi and NFC for easy image transfer and remote control via smartphone apps. Leica X2 provides no wireless networking options - a downside in today’s increasingly connected workflows.

Practical Performance Across Photography Genres

Let’s break down how these cameras perform across common photography disciplines. I’ve tested both extensively and gathered typical usage insights.

Portrait Photography

Sony RX1R II stands out with its 42MP full-frame sensor producing exquisite skin tone gradations, luminous detail, and the ability to render smooth bokeh thanks to its f/2 lens. Its face detection autofocus is competent enough for working professionals wanting sharp eye focus. Leica X2’s 16MP APS-C sensor captures flattering images but can’t match the resolution and shallow depth of field for creamy portraits.

Landscape Photography

Dynamic range and highest resolution favor Sony’s RX1R II, letting you retain subtle highlight and shadow detail and crop aggressively if needed. Leica’s APS-C sensor is adequate for moderate landscape work; however, the fixed f/2.8 lens limits light gathering and slightly restrains background separation. Note, neither camera offers weather sealing - outdoor landscape shooters should take precautions.

Wildlife and Sports Photography

Neither camera is purpose-built for fast-paced action or wildlife photography. They lack extensive autofocus tracking, high burst rates, or weather protection. But if you’re shooting slower-moving subjects, the RX1R II’s faster autofocus and 5 FPS burst can suffice for casual wildlife. Leica’s more limited AF makes it less flexible here.

Street Photography

Here’s where Leica X2 shines. Its compact size, quiet shutter, and classic rangefinder-like aesthetic make it discreet and easy to carry for urban environments. Sony RX1R II is still portable but slightly larger and more conspicuous. Still, if you prefer sharper files and better low-light capability, RX1R II’s performance may justify the tradeoff.

Macro Photography

The Sony RX1R II’s close focus distance of 14cm lets you approach subjects much nearer than Leica’s 30cm limit, enabling tighter framing on small objects. Focus precision and sharpness at these distances are superb with RX1R II.

Night and Astrophotography

In low light and night scenarios, high native ISO and sensor performance are critical. Leica X2’s max ISO of 12500 is serviceable but starts to show noise beyond ISO 3200. The RX1R II boasts a max ISO of 25600 (boost up to 102400) with better noise control and retains dynamic range. While neither sports dedicated astro modes, the RX1R II’s sensor lends itself far better to night sky imaging.

Video Usage

If video is a priority, Sony RX1R II is by far the practical choice. Full HD capture, microphone input, and established codec support meet the basic needs of multimedia creators. Leica X2’s total absence of video precludes its use beyond stills-focused work.

Travel Photography

Portability and battery life are key here. Leica X2’s smaller weight and longer battery life make it a lighter companion for day trips and quick shoots. The RX1R II’s superior image quality and 35mm lens are great but come with an added size and need for battery management.

Professional Workflows

Sony RX1R II’s ability to shoot 14-bit uncompressed RAW files at 42MP, together with robust color depth and dynamic range, aligns well with professional workflows requiring extensive post-processing latitude. Connectivity features allow easy integration into networked environments. Leica X2 provides 14-bit RAW but at a lower resolution and less dynamic range, suiting photographers less reliant on heavy retouching.
