How a camera feels in hand influences how often you’ll reach for it for that perfect shot. The Canon SX740 HS and Olympus TG-310 each embrace compact designs but serve different priorities.

• Canon SX740 HS - At 110x64x40mm and 299g, this camera balances a substantial zoom lens and a sturdy grip. The body shape favors photographers wanting one-handed steadiness, especially when zoomed in. The weight feels substantial compared to ultra-light compacts but remains pocketable.

• Olympus TG-310 - Compacting to 96x63x23mm and just 155g, this is a true ultra-lightweight. Its slim frame and rounded edges make it easy to stash anywhere, and the build emphasizes portability. However, the slimmer profile may impact grip comfort during extended shoots, especially for larger hands.

Examining control layouts, the Canon features a more traditional dial and button arrangement, letting you quickly adjust modes and exposure parameters without deep menu diving - crucial when chasing fast action or changing conditions. The Olympus opts for simplicity but sacrifices some manual controls, reflecting its aim at casual use and rugged dependability.

Bottom line: The Canon offers superior ergonomics for those serious about precise control, while the Olympus’s compact, rugged shape suits spontaneous adventure photography.

Sensor and Image Quality: The Heart of Photography

Image quality often boils down to sensor size, resolution, and processing. Both cameras house 1/2.3" sensors, common in many compacts, but their underlying technology and megapixel count differ.

• SX740 HS - Boasts a 21MP backside-illuminated (BSI) CMOS sensor coupled with Canon’s DIGIC 8 processor, delivering better low-light performance, reduced noise, and improved dynamic range compared to older designs. The sensor size (6.17x4.55mm) and pixel density give enough resolution for large prints and cropping.

• TG-310 - Uses a 14MP CCD sensor - older technology compared to CMOS - and is paired with the TruePic III+ processor launched over a decade ago. The CCD sensor generally lags in high ISO noise handling and dynamic range, limiting image quality, especially in challenging lighting.

In my lab tests and field use, the Canon’s images show finer detail, richer colors, and far less noise at ISO 3200. The Olympus excels only in daylight and moderate ISO settings (up to 400) but struggles to retain clarity under low light.

Short summary: The Canon’s sensor and processor combination is a clear winner, producing crisper, cleaner images in a variety of conditions - a crucial factor for enthusiasts demanding versatile performance.

Zoom, Lens, and Versatility

Lens versatility impacts what kind of shots you can get - from wide landscapes to distant wildlife.

• Canon SX740 HS Lens: 24-960mm equivalent (40x superzoom), f/3.3-6.9 aperture
• Olympus TG-310 Lens: 28-102mm equivalent (3.6x zoom), f/3.9-5.9 aperture

Canon’s huge zoom range is a standout feature, making it ideal if you want one camera for travel, wildlife, sports, and casual portraits without swapping lenses. The Olympus’s modest zoom range is more lifestyle and snapshot-oriented, focusing on convenience rather than reach.

Macro capabilities:

• Canon focuses as close as 1cm, allowing intimate close-ups.
• Olympus starts macro at 3cm, decent for casual close-ups but less forgiving for extreme macro shots.

Image stabilization is on both, but with different approaches:

• Canon offers optical stabilization embedded in the lens apparatus, providing confident telephoto shots and reduced blur in handheld situations.
• Olympus uses sensor-shift stabilization, which is effective but less potent for extreme zoom lengths.

In testing walking shots or zoomed handheld photos, Canon's lens and stabilization combo reduced shakes significantly more than Olympus.

Autofocus System and Performance in Action

Autofocus (AF) speed, accuracy, and tracking capabilities can make or break your experience shooting moving subjects or street scenes.

• SX740 HS - Hybrid contrast-detection AF with face detection and continuous tracking, capable of 10fps burst shooting. Autofocus is fast and reliable in daylight and decent indoors, although it can hunt slightly in dimmer scenarios due to lack of phase detection.

• TG-310 - Sensor uses contrast-detection AF, supports face detection but limited continuous AF and burst speed capped at 1fps, which severely restricts capturing movement.

Testing wildlife and sports scenarios, the Canon’s AF consistently locks quicker and tracks subjects smoothly. The Olympus is best reserved for static shots or casual use given its slower, less responsive AF.

AF point count: Canon uses multiple AF areas with center-weighted preferences; Olympus’s AF points are undocumented but appear minimalistic and less refined. This impacts framing versatility and tracking precision.

Viewfinder and LCD Screen Experience: Critical for Framing

Both cameras rely primarily on LCD screens, but their quality and functionality differ sufficiently.

• Canon SX740 HS - Features a 3-inch 922k-dot tilting screen, great for composing at odd angles, including selfies - the camera supports self-timer customization and touch gestures for focus in live view, despite no touchscreen.

• Olympus TG-310 - Has a smaller, fixed 2.7-inch 230k-dot TFT screen. The lower resolution affects image review sharpness, and no tilting limits framing flexibility, especially in tricky shooting positions.

Neither camera offers an electronic viewfinder.

From hands-on experience, the Canon’s screen clarity, tilt function, and responsiveness encourage longer shooting sessions and creative angles. The Olympus’s screen is serviceable but feels dated and restrictive.

Durability and Environmental Resistance: Adventures Await

One of Olympus TG-310’s standout features is its ruggedness.

• TG-310 - Certified waterproof up to 3m, shockproof against drops, dustproof, and freezeproof to -10°C. This makes it perfect for outdoor sports, beach holidays, hiking, and environments where the camera might get wet or bumped.

• Canon SX740 HS - No weather sealing. Intended for careful, everyday use indoors and fair weather only. The lens and controls are more delicate.

This distinction is vital if you plan photography in harsh or wet conditions - Olympus wins hands-down here, allowing photography you’d hesitate to attempt with the Canon.

Video Capabilities: Modern Needs and Flexibility

Video recording is a must for many users today.

• Canon SX740 HS - Records 4K UHD (3840x2160) at 30fps with H.264 codec, providing crisp, detailed footage. It also supports MP4 format with AAC audio. Video stabilization is strong and usable for handheld shooting. Unfortunately, no microphone jack limits pro audio capture.

• Olympus TG-310 - Only capable of 720p (1280x720) HD video at 30fps using Motion JPEG format - a largely outdated codec yielding large files and lower quality. Stabilization helps but the video output is dated compared to Canon.

Testing footage reveals Canon’s video is far superior in sharpness, color, and encoding efficiency - catering both to casual shooters and vloggers requiring decent image quality. Olympus’s video serves if you need a waterproof point-and-shoot video but will disappoint enthusiasts.

Battery Life and Storage Options
