Samsung NX11 vs Samsung SL620: An In-Depth Camera Comparison for Enthusiasts and Pros

When navigating the camera market, choosing the right gear often means balancing budget, technical needs, and ergonomic preferences. Today, we’ll dive deep into a practical comparison between two Korean-made cameras aimed at vastly different users: the Samsung NX11, an entry-level mirrorless camera introduced at the tail end of 2010, and the Samsung SL620, a compact point-and-shoot from early 2009. While both share the same broad brand heritage, they serve different purposes, and their feature sets reflect this divide.

Having personally tested thousands of cameras over 15 years - from entry-level DSLRs to high-end mirrorless and compacts - I’ll guide you through detailed technical analyses, real-world shooting insights, and best-use case recommendations. Let’s find out which of these two Samsung cameras might be the right choice for your photography journey.

First Impressions: Size, Handling, and Ergonomics

Choosing a camera often starts with how it feels in hand and how convenient it is for your shooting style.

The Samsung NX11 adopts a classic SLR-style mirrorless body, measuring approximately 123 × 87 × 40 mm and weighing about 500 grams. This heft and form factor appeal to users who want DSLR-like ergonomics with more compact dimensions. The NX11’s body has substantial grip contours, dedicated dials for exposure modes (shutter priority, aperture priority, manual), and a solid feel, which I found comfortable for extended shoots.

In contrast, the Samsung SL620 is an ultracompact point-and-shoot measuring just 92 × 61 × 23 mm and tipping the scales at 168 grams - over three times lighter and significantly slimmer. This makes the SL620 highly portable, slipping easily into a pocket or small bag, an advantage for casual users or travelers who prioritize convenience over extensive manual control.

This size contrast profoundly affects handling:

• NX11: Best suited for deliberate shooting, with better grip and physical controls for quick adjustments.
• SL620: Ideal for spontaneity and snapshots but limited in manual operation and stability due to its tiny size.

Control Layout and Interface Experience

Ergonomics tie into how controls are organized and respond during use.

The NX11 features a robust top layout with mode dials, dedicated exposure compensation buttons, and shutter speed/aperture control designed for tactile feedback. The presence of an electronic viewfinder and a 3-inch 614k-dot OLED screen offers flexibility in composition.

Conversely, the SL620 has minimal physical controls - no external dials for manual exposure, and its menu-driven settings rely heavily on navigating LCD menus. Its fixed 2.7-inch screen with lower resolution makes framing and reviewing images less satisfying than the NX11’s bright, high-res OLED.

From personal pacing tests and shooting sessions:

• NX11’s physical controls significantly enhance workflow speed, ideal when quick exposure changes or ISO tweaking are needed - such as in event photography.
• SL620’s control simplicity works for users who want point-and-shoot ease without juggling dials.

Sensor Technology and Image Quality: The Core of Photography

A camera’s sensor and processing pipeline hugely influence image detail, dynamic range, and noise handling - factors I obsessively test against industry benchmarks.

Samsung NX11

• Sensor: APS-C CMOS at 15MP (23.4 × 15.6 mm)
• Processor: DRIM Engine
• ISO Range: 100–3200 native
• RAW Support: Yes
• Dynamic Range (DxOMark): 10.8 EV
• Color Depth: 22.7 bits
• Low Light ISO Score: 553 (moderate for 2010 sensor tech)

This APS-C sensor size in the NX11 is a major step up versus typical point-and-shoots, offering better noise control at higher ISOs and more detailed images. The inclusion of an anti-aliasing filter helps reduce moiré but slightly softens fine detail. I tested the dynamic range in controlled studio lighting and outdoor scenarios and found the NX11 captures highlights and shadows well, providing flexibility for landscape and portrait editing.

Samsung SL620

• Sensor: 1/2.3-inch CCD at 12MP (6.08 × 4.56 mm)
• ISO Range: 80–1600
• RAW Support: No
• DxOMark Data: Not officially tested, but expected performance is modest due to sensor size and CCD tech.

The much smaller SL620 sensor limits image quality potential, especially in low light and in scenes requiring extensive dynamic range. CCD sensors from this era often deliver pleasant home snapshot images with good color rendition but struggle with noise and highlight retention as sensitivity increases.

In practical terms, I observed softening and notable noise starting at ISO 400 in SL620 images, while the NX11 maintained cleaner images at ISO 800 and usable files up to 1600.

Autofocus Performance and Usability

Fast, reliable autofocus is a critical spec for wildlife, sports, and everyday shooting. I evaluate AF systems based on speed, accuracy, and tracking capability.

• NX11: Contrast-detection AF with 15 focus points, face detection, continuous AF, and selectable AF areas.
• SL620: Contrast-detection AF, center-weighted, face detection, no continuous AF.

The NX11’s 15-point AF system, while not cutting-edge by today’s standards, offers better flexibility and accuracy, especially in well-lit conditions. I found that AF acquisition is quick but struggles in very low light or with moving subjects due to lack of phase detection or hybrid AF. Manual focus is supported for critical control, useful in macro or low contrast situations.

The SL620’s autofocus is slower and less versatile, focused on general ease of use rather than speed or precision. It performs best with static subjects in bright conditions, making it less suitable for action or wildlife photography.

Lens Ecosystem and Versatility

An interchangeable lens system grants a photographer creative and technical freedom unmatched by fixed lens compacts.

• NX11: Samsung NX mount with over 30 lenses available, ranging from wide-angle primes, telephotos, macro lenses, and fast apertures.
• SL620: Fixed 35-175mm equivalent (5x zoom), aperture f/2.8–5.7.

The NX11’s compatibility with variety of lenses is a huge plus. Whether you prefer portraits with creamy bokeh, landscapes requiring sharp wide angles, or wildlife needing telephoto reach, you can adapt the NX11 accordingly. In my field tests, the quality of Samsung’s NX lenses is reasonable but not on par with major brands - still adequate for the price point, especially beginner or hobbyist photographers.

The SL620 is limited to its built-in zoom lens. While the 5x zoom range covers many everyday scenarios, optical quality declines significantly at telephoto end and wide apertures struggle in low light. Macro focus comes down to about 5 cm, decent for casual close-ups.

Build Quality and Environmental Protection

Durability matters if you plan to shoot outdoors or in challenging conditions.

• Neither the NX11 nor SL620 offers weather sealing, dustproofing, shockproofing, or waterproofing.
• Both have plastic-bodied designs geared more toward entry-level users and portability rather than rugged professional use.

The NX11’s larger form does feel sturdier with a better grip, but it’s not a weather-resistant tool. Similarly, the SL620’s compactness comes at the cost of a lightweight, less rugged build.

Display, Viewfinder, and Interface

The ability to review images and compose shots comfortably is vital.

The NX11’s 3-inch fixed OLED screen (resolution: 614k dots) delivers bright, crisp images with rich color and high contrast. This aids in judging focus and exposure, particularly useful in harsh sunlight.

The SL620’s smaller 2.7-inch LCD with 230k dots appears dimmer and less detailed. Additionally, since it lacks any viewfinder, composing in bright environments becomes challenging.

For photographers used to electronic viewfinders or bright screens, this difference is notable.

Battery Life and Storage

Shooting duration and storage convenience can affect your experience on a shoot or travel trip.

• NX11: Uses Samsung BP1130 battery, rated approximately 400 shots per charge.
• SL620: Exact battery model and longevity unspecified, but due to smaller size and non-interchangeable battery, expect shorter life (commonly 200–300 shots).

Both cameras use SD/SDHC cards, with the SL620 supporting MMC cards alongside SD.

If you plan longer outings or professional use, the NX11’s battery life and ability to swap batteries offer better flexibility.

Video Functionality

While neither camera is positioned as a videographer’s dream, it’s worth examining their specs:

• NX11:

  • Maximum video resolution: 1280x720p at 30 fps
  • Format: H.264
  • No microphone/headphone ports, basic video capabilities

• SL620:

  • Maximum video resolution: 640x480 at 30 fps
  • Format: Motion JPEG (much larger file sizes, poorer compression)

Neither camera provides advanced video features like 4K recording or in-body stabilization. The NX11’s HD video at 720p is a modest advantage, but overall video is an entry-level complement rather than a main feature.
