Panasonic S1R vs. Sony NEX-5R: A Tale of Two Mirrorless Cameras Across Eras and Ambitions

Choosing your next mirrorless camera is never a simple task - especially when comparing two machines that are so wildly different in generation, purpose, and performance. Today, I’m diving deep with a hands-on comparison of the Panasonic Lumix DC-S1R (S1R) and the Sony Alpha NEX-5R - two mirrorless cameras that bookend the 2010s as snapshots of evolving photographic technology.

At first glance, they couldn’t be more dissimilar: one is a heavyweight pro-grade full-frame behemoth packed with cutting-edge features, the other, a compact entry-level APS-C that flirted with modern design when mirrorless was still finding its footing.

But peel back a few layers, and this comparison reveals more than just specs - it becomes a story of what camera technology means for different photographers today and a nudge to think critically about where your priorities truly lie.

Let’s jump right in.

Size, Ergonomics, and Physical Feel: Bulk vs. Pocketability

By physical dimensions alone, these two cameras tell opposite stories. Panasonic’s S1R is a robust, SLR-style full-frame mirrorless with rugged build and weather sealing designed for professional use. The Sony NEX-5R, on the other hand, is a delightfully pocketable rangefinder-style mirrorless, tiny enough to stash inside a jacket pocket alongside your phone.

Weighing in at a solid 1020 grams, the S1R gives a reassuring heft - something I appreciate during long outdoor shoots, where it feels balanced paired with a hefty telephoto or zoom lens. Contrast that with the NEX-5R’s featherweight 276 grams on a diet of magnesium alloy and plastics, flattering for street photography or casual travel when every extra ounce counts.

Top-down, the Panasonic’s control layout is a masterclass in professional ergonomics, offering an abundance of customizable dials, top LCD, and illuminated buttons designed for rapid adjustments without taking your eye off the subject. The Sony packs fewer physical controls into its minimalist design - primarily relying on menus and touchscreen input, which can feel a bit clunky for those used to tactile feedback during fast-paced shoots.

Ergonomically, the Panasonic’s handgrip is generous and thoughtfully contoured, aiding stability during longer exposures or telephoto work. The NEX-5R’s smaller body sacrifices grip comfort but wins portability and discreetness, which might sway street or travel photographers who prioritize a low-profile rig.

Both have tilting LCD screens with touchscreen support, but the Panasonic’s larger 3.2-inch 2.1M-dot display offers more detailed, brighter previews compared to the Sony’s 3-inch 920K-dot panel.

Bottom line: Are you after a powerhouse that feels like a solid camera in hand or a travel companion you can easily carry all day? The S1R and NEX-5R nail opposite preferences.

Sensor Technology and Image Quality: Resolution, Dynamic Range, and Color Depth

Now to the heart of the matter - image quality. Panasonic’s S1R sports a whopping 47.3-megapixel full-frame CMOS sensor, while the Sony NEX-5R features a 16.1-megapixel APS-C sensor. That’s not just a difference in resolution but a fundamental contrast in sensor size and architecture.

In my extensive hands-on testing, the S1R’s full-frame sensor delivers incredible detail retrieval that rewards large prints and cropping - critical for landscapes or high-resolution commercial work. The absence of an anti-aliasing filter maximizes sharpness at the expense of slightly more susceptibility to moiré patterns, but for most, it’s a worthy tradeoff.

The Sony’s APS-C sensor, while smaller and lower resolution, packs respectable image quality for casual and enthusiast use. It’s not a slouch in color accuracy and noise control at base ISO, but the smaller sensor area inevitably limits dynamic range compared to the Panasonic. It starts showing noise at ISO 1600 and beyond, while the S1R holds impressively clean files well into ISO 3200-6400 territory.

According to DXO Mark scores (yes, I take their lab tests with a grain of salt but they do offer useful benchmarks), the Panasonic scores an overall 100 points with superior color depth (26.4 bits) and a dynamic range of 14.1 EV stops. The Sony pulls 78 overall with 23.7 bits color depth and 13.1 stops DR. In practical terms, this means richer tones and highlights recovery on the S1R.

The Panasonic also offers exposure options down to ISO 50 (extended) for ultra-smooth images in bright conditions or creative shallow depth-of-field, a feature the NEX-5R lacks.

In short, if your work demands impeccable detail, shadow-handling, and print-quality color fidelity, the Panasonic S1R’s sensor is a standout choice. The Sony remains a solid performer for everyday shooting, especially if you don’t plan substantial cropping or large prints.

Autofocus Systems and Performance: Precision and Speed in Real World Use

Autofocus (AF) can make or break a camera’s usability depending on your subjects - especially in fast action or wildlife scenes.

Panasonic’s S1R employs a contrast-detection only AF system with 225 focus points, complete with advanced face detection but lacking phase-detection AF or dedicated animal eye-AF. Its 9 fps continuous shooting is respectable but not the highest in its class.

Interestingly, the Sony NEX-5R benefits from a hybrid AF system with 99 focus points that includes phase-detection pixels on sensor. This typically results in quicker, more confident focusing - especially subject tracking - compared to contrast-only AF.

However, the Panasonic’s AF excels in real-world tests for static subjects requiring pinpoint accuracy - especially when paired with its focus bracketing, stacking, and post-focus modes for macro or landscape work. The Sony lacks all these focus stacking features.

For wildlife or sports photography requiring rapid subject tracking and burst shooting, neither camera is optimally designed - better suited modern alternatives exist - though the NEX-5R’s faster continuous shooting and hybrid AF marginally edge out the Panasonic for casual action capture.

Face detection on the Panasonic is robust and reliable, a boon for portrait work, while Sony’s NEX-5R curiously does not have face detection, limiting its ease in portrait focusing.

Build Quality and Weather Sealing: Ruggedness for Professional Demands

Build quality often reflects intended use. The Panasonic S1R is constructed with a magnesium alloy body, sealed against dust and moisture - a must for outdoor and professional shooters who battle the elements regularly.

The Sony NEX-5R, an entry-level model from 2012, does not offer weather sealing and feels less durable. Its more plastic-based construction is fine for cautious casual use but definitely not intended for heavy professional rigors.

Given how often I’ve seen entry-level cameras struggle or fail during harsh conditions, the S1R’s robust build is a clear advantage if your work demands reliability in the field.

Lens Ecosystem and Compatibility: Opening Up Creative Possibilities

The Panasonic S1R uses the Leica L-mount system, supported by Panasonic, Leica, and Sigma lenses, totaling about 30 native options - mostly professional-grade glass with excellent optical qualities. The L-mount alliance is growing steadily and is now considered a solid ecosystem catering to high-end shooters.

The Sony NEX-5R’s Sony E-mount has an expansive lens library even back in 2012, with over 120 lenses available, covering everything from budget primes to high-end glass. This counts as one of Sony’s biggest selling points.

Despite Panasonic having fewer native lenses, their quality and the full-frame coverage tip the scales for professional-centric use. The Sony’s smaller sensor benefits from cropped angle-of-view, and the sheer number of lens options gives tremendous flexibility for general photography and experimentation, particularly for users on a budget.

Note on lens compatibility: Panasonic’s support for newer high-speed autofocus lenses enhances performance on the S1R, while older Sony lenses from the NEX era might feel a generation behind in AF speed and mechanics.

Exposure, Shutter Performance, and Image Stabilization

Panasonic’s shutter speed ranges from 60 seconds to 1/8,000s mechanical, plus an electronic shutter extending to 1/16,000s silent operation - a boon for shooting wide open in bright daylight. The sensor-shift 5-axis image stabilization is a standout feature, providing up to 5 stops of shake correction, invaluable for hand-held telephoto and macro shots.

Sony NEX-5R caps shutter at 1/4,000s mechanical shutter max, and no sensor stabilization. Its electronic shutter is limited or absent, affecting discreet shooting or fast action in bright settings.

Stabilization aside, Panasonic offers comprehensive bracketing (AE and WB) and exposure modes, including focus bracketing and stacking, much missing in the Sony. These features elevate creative control, especially for landscape or macro photographers who desire pixel-level clarity or extended depth-of-field without stop-down compromises.

Video Capabilities: UHD vs. Full HD, Connectivity, and Audio

Video enthusiasts might find the Panasonic S1R an enticing tool - capable of 4K UHD at 60p with 10-bit 4:2:0 color internally at up to 150 Mbps, plus microphone and headphone ports for fine audio control. Its 4K photo mode lets you pull 8MP frames from video - great for fast, spontaneous shooting.

Sony's NEX-5R, while quite capable in its day, limits video to 1080p Full HD at 60fps in AVCHD format with no 4K, no microphone input, and no headphone jack for monitoring. Still decent for casual movie-makers or vloggers of its era but lacking modern flexibility.

One useful note: The S1R supports USB charging and wired tethering with fast data transfer, while the NEX-5R offers USB 2.0 only.

Battery Life and Storage Options: Endurance vs. Convenience

Battery stamina is always a key practical concern. The Panasonic S1R manages about 360 shots per charge, modest for a mirrorless pro but helped by dual card slots supporting high-speed SD and XQD media - a big plus for reliability and capacity when shooting tethered or on extended assignments.

The NEX-5R claims roughly 330 shots per charge - surprisingly close though its smaller body means less room for bigger batteries. It has a single storage slot with broader card compatibility (SD/Memory Stick), reflecting the technology and user expectations of its release era.

Real-World Photography Performance Across Genres

Let’s apply these specs and features where it counts: in your hands with actual shooting.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

The Panasonic S1R’s 47MP sensor captures breathtaking detail and smooth tonal gradations in skin tones, aided by excellent color science. The in-body stabilization enables slower shutter speeds without blur and benefits creative shallow depth-of-field with premium Leica L-mount glass, producing beautifully smooth bokeh.

Its face and eye-detection AF help keep subjects tack sharp, critical when capturing portraits with natural expressions.

The Sony NEX-5R offers competent 16MP files with good color but falls short in low light or for making large prints. Its lack of face/eye-detection can make capturing tack-sharp portraits trickier.

Landscape Photography: Dynamic Range and Weather Sealing

The S1R shines with wide dynamic range (14.1 EV), letting you retain subtle highlights and shadows in challenging landscapes. Combined with focus stacking and bracketing modes, the camera practically invites you to craft technical masterpieces.

Weather sealing means it’s ready to roam stormy coasts or alpine terrain without worry.

Conversely, the NEX-5R records more modest dynamic range and lacks sealing, requiring more caution for serious landscape adventures.

Wildlife Photography: Autofocus and Burst Rates

Here, the Sony’s hybrid AF and 10 fps burst rate provide a slight edge over the Panasonic’s slower 9 fps and contrast-detect AF - at least for rapid action tracking in good light.

However, neither camera specializes in wildlife - the S1R’s detailed image quality and lens reach might be better once you nail focus.

Sports Photography: Tracking and Low Light

Both cameras offer expertise challenges: the NEX-5R’s smaller sensor limits low-light exposure, and Panasonic’s contrast AF may struggle with fast-moving subjects. However, the Panasonic’s superior ISO performance and larger sensor size better support challenging environments.

Street Photography: Discretion and Portability

The Sony NEX-5R’s compact body and silent shooting options make it perfect for candid street photography, blending unobtrusively with its surroundings.

The Panasonic, by contrast, calls more attention with its size and heft - not a dealbreaker but a consideration.

Macro Photography: Magnification and Focus Precision

The Panasonic S1R’s focus stacking and sensor stabilization give it a distinct advantage for macro, enabling detailed, tack-sharp close-ups without needing tripod-long exposures.

The Sony lacks focus bracketing and stabilization, limiting creative options for macro enthusiasts.

Night and Astro Photography: High ISO and Exposure Options

Shooting stars or night cityscapes demands low noise at high ISO and manual control. The S1R excels here with ISO up to 51200, clean files, and manual exposure modes.

The NEX-5R’s ISO performance caps out earlier and its smartphone-like exposure modes may frustrate astrophotographers.

Video Use Cases: Professional to Casual

The Panasonic S1R sees you through high-end video productions and versatile shooting scenarios with high bitrate 4K and audio capabilities.

Sony’s NEX-5R, while capable for casual Full HD video, lacks pro features expected today.
