Canon SX620 HS vs Samsung NX300M: A Thoughtful Exploration for Enthusiasts Seeking the Right Camera

When comparing cameras from different categories and eras, context is key. The Canon PowerShot SX620 HS and the Samsung NX300M serve different photographic philosophies: one is a compact superzoom optimized for travel convenience, while the other is an entry-level mirrorless designed for richer image quality and creative control. I’ve spent years testing cameras across genres - portrait to wildlife, landscapes to street - and in this in-depth comparison, I’ll walk you through what these two cameras offer, where they excel, and who they best serve.

Let’s dive into their physical designs, sensor capabilities, autofocus performance, and overall versatility - trust me, it’s worth knowing these subtleties before deciding which one fits your style and budget.

Size and Handling: Portability Versus Control

First impressions matter, especially when carrying your camera all day. The Canon SX620 HS is a classic compact superzoom - small, light, and pocketable. Its dimensions (97x57x28mm) and weight of just 182 grams make it ideal for travel photographers who want to pack light but still need an astonishing 25x zoom capability.

On the other hand, the Samsung NX300M leans into the mirrorless rangefinder-style body, offering more substantial grip and controls. It measures 122x64x41mm with a heftier 331 grams. This isn’t exactly a pocket camera but remains compact compared to DSLRs, allowing comfortable handholding for extended periods.

When I tested these two side by side, I appreciated the SX620 HS's portability - perfect for spontaneous street or travel shots. But the NX300M's wider body and pronounced grip made manual focus and button accessibility easier during longer sessions or when shooting outdoors. The NX300M also includes a tilting touchscreen, a feature completely absent on the SX620 HS, which retains a fixed 3” LCD.

For photographers used to manual operation and customizable setups, the NX300M felt more natural and less constrained. The SX620 HS is, however, more of an “out-of-the-bag-and-shoot” solution, trading control for sheer convenience.

Design and Control Layout: What’s Under the Hood?

Navigating camera controls quickly impacts how often you miss a shot. I find that cameras with well-thought layouts and tactile buttons win for usability.

On the Canon SX620 HS, you'll notice a minimalist approach: few buttons, no programmable dials, and limited access to manual exposure modes. Its processor - DIGIC 4+ - while reliable for casual use, is starting to show its age in responsiveness. You also won’t find any electronic viewfinder (EVF), not even on this small sensor compact.

The Samsung NX300M embraces a more traditional camera interface. It includes a mode dial with shutter priority, aperture priority, and manual exposure modes - important for enthusiasts craving hands-on control. With 247 autofocus points spread across the frame and a touchscreen allowing for touch-to-focus and quick menu navigation, you get a user experience akin to higher-end mirrorless systems of its time.

While neither camera features an EVF, I much preferred the NX300M’s OLED screen for its clarity and color fidelity, especially in daylight. The SX620’s 922k-dot fixed LCD is decent but can struggle under bright conditions and does not offer touch input.

Sensor Size and Image Quality: The Heart of the Matter

Here we reach the critical technical divide between these two cameras.

The SX620 HS sports a 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55mm, ~28 mm²), typical for superzoom compacts but limited in light gathering and dynamic range. It has 20 megapixels, which sounds impressive but larger pixel counts on small sensors tend to increase noise and reduce low-light performance.

The Samsung NX300M houses an APS-C CMOS sensor (23.5 x 15.7mm, ~369 mm²), almost 13 times larger in area, also with approximately 20 megapixels. The larger sensor surface is significant - it captures more light per pixel, enabling better image quality, richer color depth, and improved low-light capabilities. This sensor also features phase-detection autofocus, a rarity for cameras of its age and price, delivering snappier and more accurate focusing.

In practical testing of landscapes, portraits, and everyday snapshooting, the NX300M’s files are noticeably crisper, with more detail preserved in shadows and highlights. The SX620 HS tends to produce images that are softer and show noise creeping in beyond ISO 800, whereas the NX300M handles ISO 3200 with more confidence.

Portrait skin tones appeared warmer and more natural on the NX300M, complemented by the ability to mount fast prime lenses that deliver beautiful background separation (bokeh). The SX620 HS’s fixed zoom lens (25–625mm equivalent) offers reach but suffers from a narrower aperture range (f/3.2–6.6), limiting shallow-depth effects.

Autofocus and Shooting Speed: Keeping Up with the Moment

Autofocus speed and burst rate often make or break a camera’s usefulness for dynamic subjects.

• Canon SX620 HS: Contrast-detection AF system with 9 focus points, continuous shooting at 2.5 fps.
• Samsung NX300M: Hybrid AF with 247 phase and contrast points, continuous shooting at 9 fps.

This difference is stark. In my wildlife and sports tests, the NX300M tracked moving subjects reliably almost as well as some entry-level DSLRs. Its 9 fps burst is a boon for capturing fleeting expressions or action sequences. The Canon, while capable in good light, lagged noticeably - making it a poor choice for fast-moving scenes.

Both cameras feature face-detection autofocus, but the NX300M’s system offered higher precision and better eye-focusing capability. Unfortunately, neither camera features the advanced animal eye-detection autofocus found in more recent mirrorless models.

For casual street photography or travel snapshots, the SX620 HS’s autofocus is adequate, but those who want fewer missed shots should look to the NX300M.

Build Quality and Weather Resistance

Neither camera is weather-sealed, waterproof, dustproof, or ruggedized. Both require careful handling outdoors.

The Canon feels solid for a compact and lighter weight without fragile protrusions. The Samsung’s alloy body offers a more durable and premium feel but weighs nearly twice as much. For professionals or serious hobbyists, the NX300M can sustain more wear and tear from extended use.

User Interface and Screen: Interaction Matters

The NX300M’s tilting 3.3-inch AMOLED touchscreen steals the show here, offering wide viewing angles and intuitive touch controls. Touch-to-focus, tap to take pictures, and on-screen menus accelerate workflow, especially for newcomers transitioning from smartphones.

The fixed 3-inch LCD on the SX620 HS is bright enough indoors, but lacks touch control and tilt functionality, limiting flexibility when composing creative angles.

While the Canon keeps things simple, it can feel dated if you frequently rely on touch interaction or need to shoot low or high viewpoints without discomfort.

Lens Choices and Creative Potential

This is where the Samsung NX300M shines: it utilizes the Samsung NX mount, supporting over 30 interchangeable lenses from ultra-wide, primes, telephotos to macro optics. This extensibility unlocks remarkable creative freedom.

The Canon SX620 HS is stuck with its fixed lens - an impressive 25x zoom, yes, but you cannot swap for a brighter prime, tilt-shift, or macro lens. This limitation may frustrate users who want to experiment beyond travel snapshots.

Having tested dozens of NX mount lenses over years, I confirm they offer solid image quality. Pair the NX300M body with a fast 45mm f/1.8 or 60mm macro, and you’re entering a realm of professional-looking portraits and detailed close-ups.

Battery Life and Storage

The Canon SX620 HS provides about 295 shots per charge, which matches its lightweight, travel-friendly design. The built-in battery and modest power demands help here.

The Samsung NX300M has a slightly better endurance of 330 shots but weighs more due to a bigger sensor and screen. Both cameras utilize SD/SDHC/SDXC cards and have a single card slot, standard for their classes.

Connectivity Features: Staying Modern?

Both have Wi-Fi and NFC built-in, enabling wireless image transfer and remote control apps. Neither supports Bluetooth.

The Nikon NX300M, despite its age, offers optional GPS via accessory for geotagging, unlike the Canon which lacks GPS entirely.

Video Capabilities: Beyond Still Images

Both cameras record Full HD 1080p at 30fps in MPEG-4/H.264 format. However, the NX300M provides a richer codec and manual exposure control during video - a rarity at this level.

Neither camera offers 4K recording, microphone inputs, or stabilization for video. The Canon SX620 HS features optical image stabilization benefiting handheld video, which partially compensates for the lack of other pro features.

For vloggers or serious videographers, neither camera will suffice today, but the NX300M’s manual exposure control edges ahead in creative video use.
