Samsung NX11 vs Sony A77: An Expert Field-Tested Comparison for Enthusiasts and Pros

When diving into the mirrorless and DSLR landscape of the early 2010s, two cameras stand out in markedly different categories: the Samsung NX11, an entry-level SLR-style mirrorless, and the Sony SLT-A77, a mid-size advanced DSLR featuring Sony’s translucent mirror technology. Both reflect unique technological approaches and cater to varying kinds of photographers. After personally putting these two through their paces over many shooting sessions and test environments, I’m excited to share a comprehensive, hands-on comparative review that balances seasoned technical expertise with practical usability insights.

Let’s unpack how these cameras shape up across the vast terrain of photographic pursuits – from portraits to wildlife, landscapes to video – while keeping a keen eye on their core tech and ergonomics. I’ll also dive into real-world performance and recommendations so you can confidently decide where your investment would shine brightest.

First Impressions: Size, Build, and Handling – What’s in Your Hands?

The very first tactile experience with any camera colors how you feel about shooting with it day-in, day-out. To start, consider the physical heft and design philosophy behind the NX11 and A77.

The Samsung NX11 weighs in at a nimble 499 grams, sporting dimensions of 123x87x40 mm. It’s fairly compact, especially for a mirrorless camera sporting an APS-C sensor. Its SLR-style body has a relatively shallow depth, which makes it easy to slip into smaller bags and handle casually during street walks or travel shoots.

In contrast, the Sony A77 is noticeably heftier at 732 grams with larger, more robust dimensions of 143x104x81 mm. Its design unmistakably targets enthusiasts who appreciate a DSLR’s solid grip and longer shooting sessions without fatigue. If you’re used to traditional DSLRs, the larger handgrip and pronounced control dials will feel very familiar and reassuring.

What’s impressive is how Sony manages a mid-size DSLR ergonomics but with a translucent mirror rather than a bulky reflex mirror system, which might explain slightly more compact dimensions than full pro DSLRs without sacrificing build quality or button layout.

I tested extended handheld shooting sessions with both. The NX11’s lightness is charming but less comfortable during long wildlife outings, especially with heavy telephotos. The A77’s weight gave me the confidence to shoot continuously without needing auxiliary supports.

Speaking of ergonomics...

Control Layout and Top-Plate Usability: Where Form Meets Function

Ergonomics aren’t just about size - button placement and control logic define how intuitively you interact with your camera in the moment.

The Samsung NX11 follows a more minimalist approach, with fewer physical buttons and a simple mode dial. This is true to its entry-level ambitions but might feel limiting for users who crave direct access to settings, especially while shooting fast-changing scenes like sports or street moments. Having fewer dials slows down manual adjustments.

On the other hand, the Sony A77 impresses with a more comprehensive set of dedicated controls and dual control dials for aperture and shutter speed - something every experienced shooter appreciates. The top LCD panel offers immediate shooting info, a boon when the rear screen is folded or in bright conditions.

The fully articulated 3-inch screen with higher resolution on the A77 (921k dots) further complements its user interface advantages versus NX11’s fixed 3-inch OLED screen with lower resolution (614k dots).

For those wanting quick manual control, especially in dynamic photography genres, Sony’s approach here is a clear winner.

Sensor Tech and Image Quality: The Heart of the Matter

Sensor performance is where subtlety and science meet art in image creation. Both cameras ride on APS-C CMOS sensors (~23.5x15.6 mm), but raw specs only tell part of the story.

Samsung’s NX11 sports a 15MP sensor - respectable for its time, delivering 4592 x 3056 pixel images. Its DRIM engine processes images with decent color depth (22.7 bits) and dynamic range (~10.8 stops), according to DxO Mark’s tests. ISO tops out natively at 3200, which limits low-light performance and noise handling.

The Sony A77 steps up with a 24MP CMOS sensor at 6000 x 4000 pixels resolution, boasting more detailed output and richer color reproduction (24.0 bits color depth). Its dynamic range is notably improved at 13.2 stops, letting shadows and highlights retain detail in demanding scenes like landscapes or backlit portraits. The A77’s high native ISO goes up to 16,000, plus extended ISO 25,600, enabling cleaner images in low light, astro, or fast-action scenarios.

In field shooting, this difference becomes meaningful:

• In shaded forest landscapes or twilight cityscapes, the A77’s extra dynamic range lets you recover shadow and highlight details with less noise.
• Portraits from the A77 reveal finer textures in skin tones, with smoother gradients.
• The 15MP NX11 images scale well for moderate prints but show limits when cropping tightly or shooting expansive landscapes.

Image file quality-wise, both cameras offer RAW support, essential for post-processing flexibility. The A77’s files maintain better latitude for exposure tweaks.

Autofocus System: Speed, Accuracy, and Reliability in Real-World Use

Autofocus can make or break certain photography styles: sports, wildlife, street - anything requiring quick reflexes.

Samsung’s NX11 relies on a contrast-detection AF system with 15 focus points and face detection. Contrast detection on APS-C was typical for early mirrorless but slower than DSLR phase detection. It includes selective AF and continuous AF during live view but lacks phase detection and true AF tracking.

Sony’s A77 opts for a hybrid system, utilizing 19 phase-detection AF points, 11 of which are cross-type sensors, combined with contrast detection. This delivers lightning-fast and accurate focus acquisition with impressive tracking during bursts - even enabling predictive focus on moving subjects.

The A77’s continuous burst rate clocks at 12fps, a significant asset for wildlife and sports photographers, compared to the NX11’s modest 3fps. In wildlife tests tracking flight or running animals, the NX11 lagged behind, often hunting for focus, whereas the A77 maintained crisp subject lock.

Portrait autofocus benefits as well: both cameras feature face detection, but A77 nails eye detection more reliably, ensuring tack-sharp eye focus even with shallow depth of field.

Build Quality and Weather Resistance: Ruggedness for Field Use

If you’re working outdoors regularly, a camera’s environmental sealing and durability become paramount.

The Samsung NX11 is a consumer-level camera with no weather sealing. It’s vulnerable to dust and moisture ingress - a caution for landscape or wildlife photographers shooting outdoors in variable conditions.

Conversely, the Sony A77 includes partial weather sealing around its magnesium alloy body, better protecting against dust and light rain. While not entirely weatherproof, it holds up well on day-long nature treks or inclement weather sessions, inspiring more confidence in challenging environments.

Display and Viewfinder Experience: Critical for Composition and Review

Both cameras use electronic viewfinders (EVFs), a departure from traditional optical viewfinders in DSLRs.

The NX11’s EVF offers 100% coverage at 0.57x magnification but at modest resolution and lacking detailed display elements. It’s decent for composing but somewhat basic in feedback.

The Sony A77’s EVF is a huge step forward: a 2.36 million-dot OLED panel with near-100% coverage and 0.73x magnification. The image is large, bright, and vivid, closely mimicking optical clarity while allowing overlays of rich autofocus and exposure info.

Additionally, the fully articulated screen of the A77 (versus fixed on NX11) facilitates shooting at odd angles or selfies – adding versatility for street, macro, or video applications.

Lens Ecosystem and Compatibility: What Glass Can You Put on Your Camera?

Lenses define creative potential more than any body feature.

Samsung’s NX mount strategy offers roughly 32 native lenses, skewed primarily toward primes and some zooms optimized for mirrorless compactness. While growing, this ecosystem suffers from fewer specialty optics (such as professional-grade telephotos or macro lenses), and third-party support is limited.

Sony’s Alpha mount (A-mount) benefits from a legacy carried over from Minolta, boasting an extensive lineup of over 143 lenses, including pro-grade telephotos, fast primes, macro, and cinema lenses - plus adaption options for many legacy optics.

For anyone serious about future-proofing and experimenting across genres (wildlife telephotos, macro, ultra-wide landscapes), Sony’s mount offers much greater flexibility right out of the box.

Battery Life and Storage: How Long Can You Shoot?

Shooting without worrying about power in the field is a significant convenience.

The NX11 is rated for around 400 shots per battery charge, using the BP1130 pack. This is decent for casual outings but needs spares for longer sessions or vacations.

The A77 offers slightly longer battery life at about 470 shots per charge via NP-FM500H, aided by efficient design and lower power consumption in the translucent mirror system.

Storage-wise, the NX11 uses a single SD/SDHC card slot. The Sony is more versatile, supporting SD, SDHC, SDXC cards, and proprietary Memory Stick Pro Duo formats, useful for photographers who migrate workflow between multiple devices.

Connectivity and Wireless Features: Sharing and Remote Control

Today’s workflows often hinge on smooth image transfer and camera control.

The NX11 essentially offers only USB 2.0 and optional GPS modules - no built-in wireless or remote control.

Sony adds built-in GPS plus Eye-Fi wireless card support for uploading and geo-tagging images on the go. HDMI is available on both for external monitors.

If tethered shooting or wireless sharing matters to you, Sony’s integrated features provide a more contemporary platform.

Video Capabilities: More Than a Still Camera

Video capabilities differ markedly, making choice dependent on your multimedia ambitions.

The Samsung NX11 offers 720p HD video at 30fps in H.264 format, sufficient for casual clips but not professional-grade.

The Sony A77 drives full HD 1080p at up to 60fps, supporting AVCHD, MPEG-4, and H.264 compression, and features an external microphone port for improved audio capture.

The A77’s articulated screen and more robust build also favor run-and-gun videography, making it a more versatile hybrid tool for multimedia creators.
