Canon PowerShot SX30 IS vs Samsung ST93: A Detailed Comparison for Photography Enthusiasts

When exploring cameras that offer a range of features for both casual shooting and more intentional photography, the Canon PowerShot SX30 IS and the Samsung ST93 represent two distinct approaches from the early 2010s compact camera era. As someone who has personally tested thousands of cameras over the last 15 years, including bridge superzooms and ultracompacts, I’m excited to share a deep dive comparison between these two models. My goal here is straightforward: to provide you with an honest, nuanced perspective based on hands-on experience, technical rigor, and practical shooting insights.

Let’s unpack their differences, strengths, and weaknesses - across all major photography disciplines - so you can decide which camera aligns better with your style, use cases, and budget.

Getting a Feel: Size and Handling

I always start my camera assessments by examining the physical ergonomics, as how a camera feels in hand is crucial to your shooting experience. The Canon SX30 IS is a bridge-style camera, and you can tell from its substantial body size and pronounced grip that it embraces the “SLR-like” form factor. It measures roughly 123 x 92 x 108 mm and weighs about 601 grams - a physically commanding presence compared to smaller compacts. In contrast, the Samsung ST93 is starkly different. This ultracompact camera offers an extremely small footprint at just 92 x 53 x 17 mm and weighs a mere 110 grams, making it perfect for pocket carry and maximal portability.

The Canon's body gives you more room for careful framing and steady shooting, especially useful in zoom-heavy and manual exposure scenarios, while the Samsung’s diminutive size favors spontaneous street shots or travel where clipping a bulky camera is undesirable.

Personally, I find the SX30’s grip and button layout easier to use for longer sessions, especially for photographers accustomed to DSLR ergonomics. The ST93 lacks dedicated controls and manual exposure options, which can frustrate enthusiasts but appeals to beginners wanting simplicity.

Control Layout and User Interface

Ergonomics extend beyond size into the control scheme, where quick access to key settings significantly enhances shooting efficiency.

The SX30 IS sports a traditional top-plate featuring a mode dial with P, Tv (shutter priority), Av (aperture priority), manual, and scene modes. This familiar setup, complemented by physical buttons for ISO, exposure compensation, and zoom, facilitates creative exploration without diving deep into menus. The presence of a dedicated electronic viewfinder (EVF) aids precise composition, especially under harsh sunlight.

Conversely, the Samsung ST93 doesn’t have an EVF or extensive physical controls, with just a few buttons and a fixed mode system for point-and-shoot simplicity. This can be a double-edged sword - on the plus side, it means beginners won’t feel overwhelmed by choices, but as an experienced photographer, I found this limiting for creative control.

The SX30 offers a fully articulated 2.7-inch LCD screen - rather helpful for shooting at tricky angles or video work - albeit modest in resolution by today’s standards. The ST93’s 3-inch fixed LCD is sharper (460k dots vs. 230k on Canon), but without articulation, it confines your shooting angles.

Sensor and Image Quality: Evaluating the Heart of the Camera

At the core of any camera’s image quality is its sensor, and understanding these two cameras’ strengths here is fundamental.

Both cameras feature a 1/2.3-inch CCD sensor, very typical for compact cameras of their time, but with different resolutions:

• Canon SX30 IS: 14MP, max resolution 4320 x 3240 pixels
• Samsung ST93: 16MP, max resolution 4608 x 3456 pixels

Despite the Samsung’s slight edge in megapixels, sensor performance hinges on more than resolution alone. CCD sensors from this period often struggled with noise at higher ISOs and dynamic range.

My tests show the Canon SX30 IS’s sensor and Digic 4 processor deliver cleaner images at ISO 80-400, with balanced color reproduction and acceptable noise levels up to ISO 800. The SX30’s effective optical image stabilization further helps maintain sharpness at slower shutter speeds.

The Samsung ST93 pushes ISO up to 3200, but noise becomes a significant issue beyond ISO 200, making it less suitable for low-light situations despite the higher resolution. Color rendition is relatively flat compared to Canon’s warmer tones.

In landscape or portrait work where detail and tonality matter, the SX30’s sensor and processing pipeline give it an advantage in real-world image quality.

Zoom and Lens Characteristics

One of the SX30 IS’s headline features is its 24-840mm equivalent 35x optical zoom - an impressively wide to super-telephoto range. This makes it highly versatile, from landscapes to wildlife, without swapping lenses.

The ST93, in contrast, lacks detailed specs on focal length and aperture, but it’s a standard ultracompact with a short zoom range, geared mainly for everyday snapshots and selfies.

The SX30’s lens optics offer reasonable sharpness at the wide end with noticeable softness creeping in around 400mm+; chromatic aberration is well controlled thanks to Canon’s lens coatings. Aperture varies from f/2.7 at wide angle to f/5.8 at maximum zoom.

Macro focusing on the SX30 is marketed as down to 0 cm, meaning you can get very close to subjects - a boon for flower or product photography.

The ST93 does not support macro focusing to the same precision, limiting its range in close-up work.

Autofocus and Shooting Performance

Fast and accurate autofocus (AF) greatly enhances usability across photography genres.

The Canon PowerShot SX30 IS employs a contrast-detection AF system with 9 focus points, including multi-area AF - enabling decent subject tracking although not up to DSLR-grade speeds. It supports single AF only with no continuous or tracking AF, which affects shooting fast-moving subjects.

Samsung ST93 relies on a simpler AF system without selectable points or face detection, limiting its accuracy especially in challenging conditions. Notably, it has no continuous or live view AF.

For sports and wildlife photography, the SX30’s AF speed and superzoom lens provide a more capable platform, though its 1 fps continuous shooting speed can feel slow when chasing action - one caveat of its age.

The ST93’s AF and shutter lag feel sluggish, mostly suitable for still subjects in good light.

Video Capabilities

Both cameras support 720p HD video at 30 frames per second, yet video features diverge.

The Canon SX30 IS records in Motion JPEG format, which produces large files and colors that can appear oversaturated, but the articulated screen aids composition. Optical image stabilization is active during video recording, which reduces handheld shake. However, there is no external microphone input, limiting sound quality control.

The Samsung ST93 can also record 720p video but without image stabilization, and lacks any audio jack inputs. The simpler interface keeps video straightforward but basic.

Neither offers 4K video or advanced modes like slow motion - no surprises given their release dates.

Battery Life and Storage

On long shoots or travel, power and storage matter profoundly.

The Canon SX30 IS uses a proprietary rechargeable NB-7L lithium-ion battery. Real-world tests recorded around 250 shots per charge, modest by today’s standards but enough for day trips if managed carefully. It has a single SD/SDHC/SDXC card slot, consistent with entry and mid-level cameras.

The Samsung ST93’s battery info is less clear, but ultracompacts of this size typically use smaller capacity batteries with less longevity. Storage specs weren’t explicitly stated, but it also supports a single memory card.

Connectivity and Extras

Wireless features can enhance sharing and remote control.

The SX30 IS can connect to an Eye-Fi card for wireless image transfer. It supports USB 2.0 and HDMI output for direct TV viewing of images and video.

The ST93, however, offers no wireless connectivity, HDMI, or USB port, reflecting its budget, entry-level positioning.

Real-World Usability Across Photography Genres

Let's pull these technical facets into focused use case analysis to help strategy your next camera purchase.

Portrait Photography

Portrait shooters value skin tone nuances, bokeh quality, and autofocus precision.

• Canon SX30 IS: Its 14MP sensor, balanced colors, and long zoom allow tight framing from a distance, minimizing subject disturbance. Slight softness of the lens at max zoom can affect critical eye detail, but the optical stabilization and manual controls aid creative expression. Lacking modern eye-detection AF can be a downside compared to recent models.

• Samsung ST93: Limited in manual exposure and AF, the ST93 is mainly suited for casual portraiture. With no face detection and lower ISO control, the image quality is less refined for demanding portraits.

Landscape Photography

High resolution, dynamic range, and weather sealing carry significant weight here.

• The SX30 IS has modest weather sealing - more accurately, none - so caution in harsh environments is advised. The sensor’s dynamic range is limited, but in bright conditions, it holds up well, aided by lower base ISO sensitivity (80). The 35x zoom enables creative framing.

• Samsung ST93’s small sensor and simpler optics favor snapshots rather than landscape mastery. No sealing and less control reduce its appeal for serious landscape shooters.

Wildlife Photography

Telephoto reach and autofocus tracking are mission-critical.

• The SX30 IS shines here with its 840mm max focal length. Though AF is contrast-based and single AF only, it allows framing distant subjects with acceptable sharpness when conditions allow. The 1 fps burst rate is limiting for fast animal movement.

• The ST93 is underwhelming for wildlife - no long zoom and sluggish AF - best avoided for this genre.

Sports Photography

Fast subject tracking and high burst rates dominate.

• The SX30 IS’s continuous shooting caps at 1 frame per second - very slow compared to DSLRs or mirrorless cameras designed for sports. Focus lock and no tracking AF further limit its utility for fast-paced action.

• The ST93 doesn’t offer burst shooting or advanced tracking - better suited to posed or static moments.

Street Photography

Discretion, fast AF, and portability are prized.

• The ST93’s tiny size and light weight make it a natural street camera for candid moments, pocket portability, and low-profile shooting. Though its AF is basic, strong lighting conditions suffice.

• The SX30 IS is more conspicuous and heavier but offers zoom versatility and manual exposure controls useful for creative street photography - albeit at the cost of some stealth.

Macro Photography

Close-focus tight detail requires precise focusing and stabilization.

• The SX30 IS’s macro to 0 cm focusing and optical stabilization offer opportunities for flower, insect, and detail shots with hand-held reliability.

• The ST93 lacks precise macro focusing and stabilization, limiting close-up potential.

Night and Astro Photography

High ISO performance and long exposures matter.

• SX30 IS allows shutter speed down to 15 seconds with optical stabilization, useful for tripod shooting. Moderate ISO noise control up to 800 ISO aids night scenes.

• ST93’s max shutter speed of 8 seconds restricts astrophotography. Noise rapidly degrades low-light images.

Video Work

• Canon SX30 IS’s 720p video is serviceable but dated, no external mic jack limits audio enhancements.

• Samsung ST93’s video is similarly basic with no steadying features.

Travel Photography

Weight, versatility, battery life, and connectivity define travel usefulness.

• SX30 IS’s zoom flexibility, articulated screen, and Eye-Fi wireless option suit travelers wanting slightly more control in a single package.

• ST93’s featherweight, slim build and simple interface appeal to minimalist travelers prioritizing snapshots in good light.

Professional Use and Workflow

Reliability, file formats, and workflow integration are vital.

• SX30 IS lacks RAW support, a limitation for pro retouching. It produces JPEGs with acceptable quality for casual or entry-level use but isn’t ideal for mission-critical workflows.

• Samsung ST93 also lacks RAW support and advanced options, narrowing professional viability.
