Having spent over 15 years photographing everything from serene landscapes at dawn to the whirlwind of a fast-paced sports event, I understand the critical importance of choosing the right camera for your specific needs. Over the years, I've tested thousands of cameras, and nothing beats the value of hands-on experience coupled with rigorous technical analysis - especially when comparing very different models like the Samsung NX20 and the Sony Cyber-shot H70.

In this detailed comparison, I share insights from direct testing, covering everything from sensor performance to autofocus capabilities, lens ecosystems, ergonomics, and how each camera fairs across a diverse set of photography disciplines. Whether you’re a serious enthusiast considering stepping up to a mirrorless system or someone seeking a simple, compact travel option, I’ll walk you through the strengths and weaknesses of each model to help you make an informed decision.

Getting to Know the Contenders: Samsung NX20 and Sony H70

Before diving in, let’s briefly look at the basics and form factors of these cameras:

• Samsung NX20: Announced in 2012, the NX20 is an advanced mirrorless camera, sporting an APS-C sensor (23.5 x 15.7 mm) and a Samsung NX lens mount, designed for enthusiasts who want more control and image quality without the bulk of a DSLR.

• Sony Cyber-shot DSC-H70: Launched in early 2011, the Sony H70 is a small sensor compact with a fixed 10x zoom lens, designed for casual photographers needing portability and simplicity.

As you can see from the size comparison image, the Samsung NX20 has a pronounced SLR-style body with a comfortable grip, while the Sony H70’s compact design fits easily in a jacket pocket or purse. This fundamental difference sets the stage for their intended audiences and usages.

Sensor and Image Quality: The Core Difference

One of the most significant influence factors on image quality is sensor size and technology.

The Samsung NX20 boasts a 20.3-megapixel APS-C CMOS sensor, roughly 369 mm² in area, which is significantly larger than the Sony H70’s 16.1-megapixel 1/2.3" CCD sensor measuring only about 28 mm². The difference in sensor size is fundamental. In practice, the larger APS-C sensor captures more light, offers better dynamic range, improved color fidelity, and cleaner images in low-light scenes.

I’ve tested the NX20 extensively at ISOs up to 3200 and found noise levels well controlled - still maintaining detail and texture for portraits and landscapes alike. In contrast, the Sony H70’s small sensor and CCD technology struggle beyond ISO 400, with noticeable grain and reduced sharpness.

If image quality is a priority - especially for print or critical viewing - the NX20 wins unequivocally. The H70 is better suited for casual snapshots, where portability trumps pixel-level perfection.

Ergonomics and User Experience: Handling Matters

Operating a camera should feel natural and intuitive - critical, especially during dynamic shoots.

The NX20 features a well-laid-out control scheme typical of advanced mirrorless cameras of its era: dedicated dials for shutter speed and exposure compensation, a handy mode dial, and customizable buttons. The electronic viewfinder with 100% coverage and 0.7x magnification provides a stable framing tool in bright environments where LCD screens falter.

Samsung’s OLED fully articulated 3" screen with 614k resolution is a joy to use, especially for low-angle or selfie-style shooting. The articulation offers flexibility for macro or street photography when eye-level composition is difficult.

The Sony H70’s fixed 3" Clear Photo LCD offers decent viewing but pales in comparison with the NX20 - both in angle flexibility and resolution (230k). With no viewfinder, eye-level shooting relies solely on the LCD, which can be challenging under direct sunlight.

While the H70’s simplified controls keep things easy for beginners, those seeking quick manual control will find the NX20 more satisfying. The lack of touchscreen on both means menu navigation leans on buttons, which the NX handles better with ergonomically placed dials.

Focusing Systems: The Eye Behind the Lens

Fast and accurate autofocus can make or break shots, particularly in wildlife or sports photography.

The Samsung NX20’s hybrid autofocus system uses a contrast-detection mechanism with 15 focus points, including face detection - though no eye or animal eye detection is available. Despite lacking phase-detection, in my real-world trials, the NX20's autofocus acquitted itself well in daylight and moderate movement scenes, providing responsive single and continuous autofocus modes up to an 8 frames-per-second burst rate.

Conversely, the Sony H70 uses a simpler 9-point contrast-detection AF system without face or eye detection; it lacks continuous AF modes and sports only a 1 fps burst, making it ill-suited for tracking fast subjects. Autofocus often hunted in low light, leading to frame delays.

For wildlife, sports, or any fast-paced environment, the NX20’s AF system is significantly more reliable even if it’s not cutting-edge by today’s standards.

Lens Systems and Versatility: The Heart of Creative Control

One of the NX20’s robust points is the available Samsung NX lens lineup. With around 32 lenses, ranging from ultra-wide to long telephoto zooms and fast primes, the system offers flexibility for nearly every photography style.

Sony H70’s fixed 25-250mm (10x zoom) F3.5-5.5 lens covers a respectable range for a compact, but optical performance drops noticeably at telephoto extremes, especially in sharpness and chromatic aberration.

Users serious about image creativity and quality will appreciate the interchangeable lens advantage of the NX20, particularly for genres like portraits and macro where prime lenses shine. For casual travel, the H70’s all-in-one lens is more convenient but less specialized.

Performance Across Photography Genres

Let’s explore how these cameras fare in common photography disciplines based on my field tests and lab evaluations.

Portrait Photography

Skin tone rendition and bokeh quality are paramount here.

With the NX20’s APS-C sensor and interchangeable lenses, portraits showcase pleasing skin tones with excellent gradation and minimal noise. Although lacking dedicated eye autofocus, face detection aids composition. Prime lenses from Samsung's lineup provide creamy bokeh and sharp eyes - critical for truly professional portraiture.

The H70’s smaller sensor and slower fixed lens deliver flatter colors and less background separation, resulting in less flattering portraits. The limited lens aperture restricts creative depth of field.

Landscape Photography

Dynamic range, resolution, and weather durability are key.

The NX20 excels, capturing over 12.9 stops of dynamic range according to DxOmark, retaining highlight and shadow detail in challenging scenes. The 20MP resolution provides ample cropping potential and large prints. Although the body lacks environmental sealing, careful use suffices.

The H70’s sensor exhibits limited dynamic range, leading to clipped skies and murky shadows. Lower resolution impacts fine detail, and the fixed lens can't match the NX20’s ultra-wide options.

Wildlife Photography

Speed and reach define success here.

The NX20’s faster continuous shooting and AF tracking modes support moderate wildlife work, especially with compatible telephoto lenses. The APS-C sensor delivers favorable reach with tele zooms.

The Sony H70’s slow burst and less responsive autofocus limit it severely in this genre, though its built-in zoom offers convenience for casual shots.

Handling Action: Sports Photography

Sports demand high frame rates and precise AF.

While the NX20’s 8 fps continuous shooting and selective AF points provide some capability for amateur sports photography, it isn’t a dedicated sports camera and may falter with very fast subjects or complex tracking.

The H70’s slower burst and lack of continuous autofocus make it unsuitable for sports.

Street Photography

Portability, discretion, and low-light performance matter here.

The H70’s compact size makes it easy to carry for spontaneous street shoots; however, its noisier high-ISO performance constrains low-light usability. Lack of a viewfinder hinders composition out in the field.

The NX20 is bulkier but offers better low-light image quality and an EVF for discreet eye-level shooting. The articulated screen adds framing flexibility, though the presence of a bigger body may draw more attention.

Macro Photography

Precision and stabilization lead the pack here.

The NX20 lacks in-body image stabilization but permits use of macro lenses with tight focusing and significant magnification, making it ideal for close-up work when paired with the correct glass.

The Sony H70 has optical image stabilization, which helps handheld focus, but its macro minimum focusing distance of 5 cm and smaller sensor limit detail resolution in macro shots.

Night and Astrophotography

Low noise and long exposure options are essential.

The NX20’s wider ISO range (base 100 to 12,800) and shutter speeds up to 1/8000s provide ample flexibility. Though it lacks silent or electronic shutter modes, long exposure handheld or tripod work produces excellent night scenes with restrained noise.

The H70 tops out at ISO 3200 with shutter speeds limited to 1/1600s, making it less versatile for astrophotography or low-light long-exposure.

Video Capabilities: Recording and Stabilization

Both cameras offer full HD video, but with differing capabilities.

• The NX20 shoots 1080p at 30fps with advanced compression (MPEG-4, H.264) and includes a microphone port for improved audio input, appealing for serious videographers.

• The H70 records at 720p at 30fps with no audio input options. It does have optical image stabilization, aiding handheld recording.

Neither features 4K recording or advanced autofocus tracking in video, but the NX20 holds the edge for higher quality footage and audio flexibility.

Travel Photography: Versatility and Battery Life

Travel demands an all-rounder.

Here, the H70’s small size and built-in zoom lens make it easier for casual travelers wanting a lightweight solution, supported by compatibility with various storage cards including Memory Stick formats.

The NX20, while larger, offers far better image quality, flexibility with lenses, and decent battery life (~360 shots per charge). The articulating OLED screen helps compose creative shots on the go.

Professional Usage and Workflow Integration

In professional contexts, reliability, file formats, and workflow matter.

The NX20 supports RAW file capture essential for maximum post-processing control, whereas the H70 only shoots JPEG, limiting professional use.

USB 2.0 connectivity is basic on both; however, the NX20 includes built-in Wi-Fi for wireless sharing, boosting convenience on shoots.

Samsung’s removable battery (BP1130) and support for external flashes ensure more robust shooting sessions.

Connectivity and Storage

Both cameras offer one memory slot for SD/SDHC/SDXC cards, with the H70 uniquely supporting Sony’s Memory Stick formats, which can be an advantage for certain users entrenched in that ecosystem.

USB 2.0 is standard, with HDMI out enabling direct TV connection.

Wireless connectivity favors the NX20, with built-in Wi-Fi compared to the H70’s Eye-Fi card compatibility only.

Build Quality and Environmental Resistance

Neither camera is weather sealed or robustly built for extreme conditions, though the NX20’s bulkier frame offers marginally better grip and durability.
