Canon PowerShot SX730 HS vs Samsung ST30: A Deep Dive Into Compact Camera Evolution

When it comes to compact cameras, few comparisons resonate more than between a solid superzoom powerhouse like the Canon PowerShot SX730 HS and an older, ultracompact contender like the Samsung ST30. Despite being launched six years apart, these two cameras represent different eras and philosophies of pocketable photography. Over the years, I’ve handled thousands of cameras - testing sensor responsiveness, ergonomics, autofocus precision, and real-world usability - and I’m excited to unpack how these two stack up against each other across crucial photographic disciplines and technical parameters.

If you’re contemplating which tiny tool suits your style - or just curious how camera tech has progressed in a half-decade - join me on this measured, practical exploration of Canon’s SX730 HS against Samsung’s ST30.

How They Feel in Your Hand: Size and Handling Matter

One of the most tangible aspects when choosing a compact camera is how it feels during extended shoots. The Canon SX730 HS is a bit chunkier, measuring 110×64×40 mm and weighing 300 grams, while the Samsung ST30 is a true pocket dweller at 82×52×17 mm, tipping the scales at just 87 grams.

Holding the SX730 HS reveals a more substantial grip and better control placement - a design catering to photo enthusiasts wanting firm handling for telephoto reach without a tripod. The tilting rear screen enhances framing versatility. The Samsung ST30’s razor-thin profile feels like a digital spy camera; it’s almost invisible in a jacket pocket but sacrifices physical feedback and ergonomic comfort, which can lead to finger slips and less composure control.

If you prize portability above all else and want a pocket-sized travel companion, the ST30 wins, hands down. However, for deliberate shooting sessions, especially with the extended zoom, Canon’s bulkier body offers superior handling and control responsiveness.

Eyecandy on Top: Control Layout and Top-View Design

Peeking over the shoulder of these cameras reveals stark differences in top-deck design and control accessibility.

The SX730 HS rocks a straightforward command dial, shutter button with zoom toggle, and dedicated mode dial enabling quick switching between manual exposure, aperture priority, and scene modes. The Samsung ST30, true to its ultra-compact ethos, trims controls to the bare minimum: a single power button and shutter release with no manual exposure options or physical dials.

In practical terms, SX730 HS users can fine-tune exposure on the fly, a critical workflow advantage for photographers accustomed to creative control. The ST30 requires reliance on automatic modes and menus, making it more a point-and-shoot device than a camera for shaping light thoughtfully.

The Heart of the Beast: Sensor Technology and Image Quality

The sensor is the lifeblood of any camera. Here, the Canon SX730 HS sports a 1/2.3" (6.17×4.55 mm) BSI-CMOS sensor with 20.3 megapixels, while the aging Samsung ST30 features a 1/3" (4.8×3.6 mm) CCD sensor with 10 megapixels. This difference alone foreshadows a significant gulf in imaging performance.

From my lab work and field trials, BSI-CMOS sensors (backside illuminated) like the Canon’s generally offer superior low-light sensitivity and dynamic range compared to CCD sensors of the Samsung’s era. The doubling in resolution means more detailed images and greater cropping flexibility. The Canon’s sensor also benefits from modern DIGIC 6 processing, delivering cleaner images at higher ISOs and improved noise control.

In contrast, Samsung’s CCD sensor delivers decent colors in bright conditions but struggles once lighting dips. It maxes out at ISO 400 with visible noise creeping at base ISO levels beyond 100, whereas the Canon can comfortably shoot up to ISO 3200 for usable results - a huge advantage for night or indoor photography.

Sharpening the View: Autofocus and Performance Under Pressure

While both cameras feature fixed zoom lenses, their autofocus (AF) systems are miles apart.

The SX730 HS employs contrast-detection autofocus enhanced by face detection and tracking, providing 5.9 fps continuous shooting to capture fast action at 960 mm optical zoom. During wildlife and sports simulations, I found its AF sufficiently fast and accurate, locking reliably on faces and moving subjects in daylight and decent indoor light. The absence of phase detection limits speed, but the contrast-based live view AF remains competent in most scenarios.

The Samsung ST30’s AF is rudimentary - contrast-based but without face detection or continuous AF tracking. It focuses sluggishly in low light, and no continuous shooting mode hampers action photography. This camera is best suited for still, posed shots under good lighting.

Seeing is Believing: Rear Screens and User Interface

A thoughtful rear display is key for composing and reviewing shots.

The SX730 HS sports a 3-inch tilting screen with 922k-dot resolution - very sharp and flexible for shooting at high or low angles. Conversely, the ST30’s fixed 3-inch screen has a mere 460k-dot resolution, making it feel dated and less clear outdoors. Neither camera offers a viewfinder, which slows composition in bright sun for both.

Canon’s interface emphasizes quick access buttons and physical dials, enhancing the shooting rhythm. Samsung’s menu-driven approach demands more time navigating settings, which can be frustrating in fast-paced shooting environments.

Real-World Image Samples: How Do They Perform?

It’s time to put pixels on the page. Let’s compare sample images under representative conditions:

Portraits made with the Canon SX730 HS exhibit pleasing skin tones and a respectable bokeh thanks to the long zoom and careful optics. Eye detection ensures subjects are tack sharp. The Samsung ST30’s portraits look flat and less detailed, with harsh skin rendition due to limited autofocus sensitivity and sensor resolution.

Landscapes shot on the Canon reveal a wider tonal range, maintaining shadow detail and producing sharp fine details that hold up to 100% inspection - a boon for landscape photographers craving color fidelity. The ST30 struggles with dynamic range; highlights clip easily and detail is soft.

The wildlife and sports test shots showcase the Canon’s faster autofocus and high shutter speeds capturing movement cleanly, whereas the Samsung produces soft focus and motion blur in comparable situations.

Night photography starkly reveals the Canon’s strength, with images retaining color and reducing noise at ISO 1600 and above. Samsung’s output quickly deteriorates, limited by sensor type and absence of image stabilization.
