Canon SX620 HS vs. Olympus TG-630 iHS: An Expert Hands-On Comparison for Every Photographer’s Needs

Choosing the right compact camera can be surprisingly complex, especially when models target distinctly different niches but share some overlapping features. Today, I’m taking a deep dive into two distinct, yet comparably priced, compacts: Canon’s PowerShot SX620 HS - a superzoom powerhouse - and Olympus’s Tough TG-630 iHS, a rugged waterproof shooter. Both are from the mid-2010s era but continue to find favor in budget-conscious circles due to their compelling specifications and capabilities.

Having logged hours shooting with both, I’ll share not only dry specs but also what really matters in actual use. Whether you lean toward adventurous travel photography or want a versatile zoom compact that slips easily into your bag, this comparison aims to be your go-to guide.

Let’s unpack their qualities - from sensor and build to autofocus and real-world image quality - across a broad spectrum of photographic disciplines.

First Impressions: Size, Feel, and Ergonomics

When putting a camera in hand for the first time, size and ergonomics immediately shape expectations. The Canon SX620 HS and Olympus TG-630 iHS are both compact, but their design intentions couldn’t be more different.

The Canon SX620 HS (~97x57x28 mm, 182 g) feels classically compact and slim - ideal for everyday carry. It’s pocket-friendly, though the slight bulkiness from the 25x zoom lens is perceptible. Olympus’s TG-630 (98x66x22 mm, 167 g), while similar in height, is notably wider and flatter. Its ruggedized exterior, sealed against water and shock, contributes to a chunkier grip profile but adds peace of mind for outdoor use.

Ergonomically, the SX620’s top and rear controls are minimal yet sufficient, catering to straightforward point-and-shoot operation. Olympus offers fewer manual controls and a simpler interface but compensates with dedicated waterproof sealing.

Top-Down: Control Layout and User Interface

Good handling extends to how intuitive the control layout is. After extensive testing, I found the Canon SX620’s control panel slightly more thoughtful for casual users who desire speedy access to zoom and playback.

The SX620 lets you zoom quickly with a well-placed rocker, paired with a conveniently placed shutter button and minimal mode buttons around it. Olympus TG-630’s top layout is simpler - fewer buttons, making it arguably more approachable for absolute beginners but less flexible for those craving even modestly manual intervention.

Neither model boasts touchscreens or articulated displays - the SX620 offers a slightly higher resolution 3-inch back screen, which aids in framing but cannot be used to tap-to-focus or adjust settings swiftly.

Sensor and Image Quality: The Heart of Every Camera

For photo quality, the sensor technology and image processing pipeline hold the key. Both cameras share the same 1/2.3-inch sensor size (28.07 mm² sensor area), a common compact standard. However, the Canon SX620 HS sports a 20-megapixel back-illuminated CMOS sensor paired with the DIGIC 4+ processor, while the Olympus TG-630 records at 12 megapixels using a standard CMOS sensor with its own image processor.

Resolution alone favors the Canon, which theoretically translates into finer detail and cropping flexibility. The BSI design in Canon’s sensor also confers better light sensitivity - a critical advantage in dim conditions. Olympus’s sensor tops out at a higher ISO (native max ISO 6400 vs. Canon’s ISO 3200), but noise can become a limitation there given the smaller pixel pitch.

In my side-by-side tests across landscape, portrait, and low-light conditions, the Canon consistently delivered cleaner, sharper images with more nuanced color gradations. The Olympus’s lower resolution and dated sensor design tended toward softer results, although its JPEG processing featured slightly punchier colors - a characteristic some users might enjoy.

See It All: Display and Interface Usability

Viewing your images on a bright, clear screen matters, especially when no viewfinder is present. Both rely on fixed 3-inch LCDs without electronic viewfinders.

Canon’s 922k-dot screen is impressively sharp for the class, enabling confident focus checking and composition. The Olympus’s 460k-dot LCD appears dimmer and less crisp in direct sunlight, which can challenge outdoor framing.

Neither offers touchscreen control or selfie-friendly tilting - the SX620’s absence of a selfie-friendly screen is a downside in today’s selfie-driven culture, though both cameras serve more conventional point-and-shoot needs.

Zoom Range and Lens Performance: Superzoom Versus Waterproof Versatility

When it comes to lenses, the Canon SX620 HS boasts a jaw-dropping 25x optical zoom range (25-625 mm equivalent) with a maximum aperture of F3.2-6.6. This is remarkable for capturing distant wildlife or detailed architectural elements without switching lenses.

The Olympus TG-630, focused on durability rather than reach, offers a 5x zoom from 28 to 140 mm equivalent at F3.9-5.9 aperture range.

In practice, Canon’s superzoom opens up creative possibilities unobtainable with the TG-630’s shorter telephoto limit. Image stabilization on both cameras helps maintain sharp shots at longer focal lengths - optical on Canon and sensor-shift on Olympus - but Canon’s SX620 lens is noticeably more versatile for scenes demanding range.

However, the Olympus’s 1 cm macro focusing threshold paired with waterproofing means it can get shots in wet, rugged conditions where the Canon would be unsafe. This direct access to extreme close-ups underwater or in harsh terrains is a unique strength.

Autofocus Systems and Shooting Speeds

Neither camera is designed for high-speed action photography, but autofocus speed and reliability do impact everyday shooting.

The Canon SX620 HS uses contrast-detection autofocus with 9 focus points and supports continuous AF as well as face detection. While not blazing fast by today’s standards, it’s sufficiently responsive for casual wildlife tracking or spontaneous street moments.

The Olympus TG-630 relies on contrast autofocus without phase detection, offering face detection but fewer reported focus zones, and notably lacks continuous AF for moving targets. Its continuous shooting maxes out at 5 fps (vs. 2.5 fps on Canon), which is a rare but useful advantage in fast burst capture while hunting for that perfect moment.

In field testing, Canon’s system felt calmer and more consistent in dynamic focus adjustments, though Olympus occasionally outpaced it in burst opportunities - at the cost of more frequent hunting in challenging light.

Burst Rate and Buffer Deep Dive: For the Action Shot

If you intend to shoot sports or wildlife with a compact, frame rate and buffer handling are key considerations.

• Canon SX620 HS: Up to 2.5 fps continuous shooting
• Olympus TG-630: Up to 5 fps continuous shooting

Higher burst rates let you capture more frames in rapid sequences, increasing the chance of catching crisp action poses. Olympus’s 5 fps burst rate is respectable in a waterproof compact but hampered by slower, less accurate autofocus.

Buffers on both cameras are modest, and neither supports raw shooting (important mostly for enthusiasts and pros), so continuous shooting sequences remain limited before slowing down.

Image Stabilization: Keeping Shots Sharp in Handheld Conditions

Both cameras include image stabilization to reduce blur:

• Canon SX620 HS uses optical image stabilization, linked to lens element shifts. It effectively combats handshake up to moderate telephoto zoom levels.

• Olympus TG-630 employs sensor-shift stabilization, moving the sensor to counteract shake, which works well for steady handheld shooting and macro shots.

In practice, Canon’s optical stabilization performs slightly better at long zoom lengths, where camera shake is most consequential. Olympus’s sensor-shift seems tuned more for low-to-mid zoom ranges and benefits macro shooting, especially underwater, where stability is harder to maintain. I relied on stabilization heavily in handheld night and macro scenes, noting steadier exposures with Olympus at closer ranges.

Video Capabilities: Quality and Flexibility

Both cameras support Full HD video recording, but with subtle differences:

• Canon SX620 records 1920x1080p at 30 fps, using MPEG-4 and H.264 codec without 4K support.

• Olympus TG-630 offers 1080p at up to 60 fps, allowing smoother motion capture for fast subjects.

Neither camera offers microphone or headphone ports, limiting audio options for video creators. No touchscreen or professional video features exist here; both are entry-level for casual videographers.

I found Olympus’s higher frame rate useful for action sequences, with smoother playback during quick panning shots. Canon’s video, while capped at 30 fps, delivered slightly better exposure stability and richer colors.

Weather Resistance and Durability: Can You Take It Anywhere?

This is where the cameras diverge the most fundamentally.
