Canon PowerShot S120 vs. Olympus Stylus 7030: A Hands-On Comparative Review for Serious Photography Enthusiasts

Choosing the right compact camera often boils down to balancing image quality, portability, and feature sets, all within a reasonable budget. Today, I’ll walk you through a detailed, real-world comparison of two small-sensor compacts that have appealed to enthusiasts looking for pocketable yet versatile devices: the Canon PowerShot S120 and the Olympus Stylus 7030 (also known as the mju 7030). Both cameras aim to deliver solid performance in a compact form, but they approach the challenge in very different ways.

Having extensively tested both models in the studio and out in the field across a wide range of photographic scenarios, from low-light portraits to handheld landscape shots and casual street photography, this review combines hands-on impressions with technical analysis. I’ll also help you understand who each camera is best suited for, so you can make an informed decision that fits your style and budget.

Let’s jump right in.

At a Glance: Design, Ergonomics, and Physical Presence

Before unpacking image quality and performance, camera handling is often the unsung hero of user experience. A well-designed body encourages creativity because it just feels good to operate.

Right away, you’ll notice differences in size and weight. The Canon S120 measures 100 x 59 x 29 mm and weighs 217 grams, while the Olympus 7030 is smaller and lighter – 93 x 56 x 26 mm and only 140 grams. For ultimate portability, Olympus wins clearly, making it a great travel or street shooter’s companion.

From personal use, the S120’s slightly larger size accommodates a more comfortable grip and better button spacing. This is crucial during fast shooting or in colder weather with gloves. The Olympus, while compact, feels slightly cramped for my hands, though the advantage here is that you can almost forget it’s in your pocket.

Top control layout and operational ergonomics further highlight Canon’s ergonomic edge. Check out the comparison:

The Canon S120 impresses with dedicated dials and more accessible exposure controls - including manual focus and a dedicated aperture ring on the lens - making it far more versatile for enthusiast photographers who prefer fine manual adjustments. Olympus, by contrast, sticks with more automated controls and minimal physical dials, reflecting its point-and-shoot heritage.

In my extensive field tests, physical confidence in the controls translated to faster framing and less fumbling. For photographers who like to tweak exposure on the fly or quickly switch between manual and automatic focus modes, the S120 feels like the more professional compact.

Sensor, Processor, and Image Quality: Breaking Down the Basics

Now to the heart of the matter: how do these tiny cameras perform where it really counts - in image quality?

The Canon S120 sports a 1/1.7" BSI-CMOS sensor sized at roughly 7.44 x 5.58 mm (41.52 mm² area), delivering 12 megapixels native resolution. This sensor uses backside illumination (BSI) technology, facilitating better light gathering, especially in dim conditions.

The Olympus Stylus 7030, on the other hand, has an older 1/2.3" CCD sensor measuring 6.08 x 4.56 mm (27.72 mm²), capturing a slightly higher 14 megapixels. The drawback here is that CCD sensors tend to consume more power and suffer increased noise at higher ISOs compared to modern BSI CMOS chips.

In real-world comparisons, the S120 pulls ahead with superior color depth (21.3 bits vs. untested for the Olympus), wider dynamic range (11.9 EV), and cleaner high-ISO performance (ISO 246 vs. not available). These numbers, combined with Canon’s DIGIC 6 processor, translate into photos with pleasant skin tones, punchy colors, and retention of highlight and shadow detail beyond what the Olympus 7030 can manage.

Low light is often the Achilles’ heel of compact cameras. In tests shooting in dim interiors and twilight, the S120’s maximum native ISO 12800, with usable results up to ISO 1600, means you can shoot handheld without flash far easier than on the Olympus, whose maximum ISO 1600 is also limited by its CCD sensor design. The 7030’s image quality at ISO above 400 showed noticeable noise and color shifts.

The S120’s wider aperture lens (f/1.8 at wide end) gives it better low-light gathering capability compared to Olympus’s f/3.0. Also, Canon’s optical image stabilization paired with the sensor lets you handhold slower shutter speeds more effectively.

Exploring Lens and Autofocus: Optical Versatility in Practice

The lens and autofocus system define what subjects you can capture and how easily.

The Canon S120 has a 5x optical zoom covering a 24-120mm equivalent focal length range, with a fast maximum aperture of f/1.8 wide-angle tapering to f/5.7 telephoto. This wider aperture lets you achieve shallower depth of field, great for portraits and isolating subjects. The Olympus 7030 offers a longer 7x zoom ranging 28-196mm equivalent, though with a slower f/3.0-5.9 aperture.

If you enjoy portraits with creamy bokeh - a smooth, visually pleasing background blur - the Canon’s lens gives you more creative freedom. The Olympus’s slower lens makes background separation tougher, especially in wide-angle or mid-range shots. When photographing small objects or macros, Canon can focus as close as 3 cm, while the Olympus goes a bit closer, to 2 cm, but image quality and control remain superior on the S120.

Autofocus-wise, the Canon incorporates a hybrid contrast-detection system with 9 focus points and several intelligent AF tracking modes, including face detection and touch focus on the LCD. This allows for accurate and quick focus acquisition, especially important for candid street or wildlife shots. The Olympus’s autofocus is contrast-detection only with fewer focus points and no face detect, making it slower and less suited for fast-moving subjects.

During my follow-up testing with moving subjects - people walking, kids playing, or pets darting around - the Canon’s autofocus consistently nailed sharp focus within less than half a second, maintaining tracking in continuous mode at up to 12 fps burst speed. The Olympus managed basic focus well but struggled with tracking and only shoots at 1 fps, which can be limiting when timing is critical.

User Interface and Screen: Viewing and Composing Your Shot

Next up - how easily can you compose your image in everyday shooting conditions?

The Canon S120 features a 3” touchscreen TFT PureColor II G LCD with 922k dots resolution, providing bright, sharp, and color-accurate live view. The touchscreen functionality offers intuitive focus point selection and menu navigation - a big plus for fast shooting.

In contrast, the Olympus 7030 sports an older 2.7” fixed LCD with only 230k dots resolution, lacking touchscreen input. The smaller, dimmer screen seriously hampers composition accuracy and reviewing images in bright sunlight.

From a hands-on perspective, the difference here is very noticeable. The Canon’s bigger, sharper screen made all controls more fluid and facilitated easier spot focusing and review of depth-of-field. Olympus’s screen demonstrated its age immediately, often requiring guesswork in bright environments.

Neither camera offers an electronic viewfinder, which might disappoint enthusiasts accustomed to composing through a viewfinder; but that’s expected in compacts at these price points.

Video Capabilities: Beyond Stills

The Canon S120 steps up with full HD 1080p video recording at 60 fps, using MPEG-4 and H.264 compression, yielding sharp, smooth footage suitable for casual videographers and vloggers alike. Its optical image stabilization helps reduce shake during handheld recording.

By contrast, the Olympus 7030 maxes out at VGA quality (640x480) at 30 fps, with Motion JPEG compression, delivering blocky and outdated-looking footage.

Neither camera supports external microphones or headphones, limiting audio flexibility. If video is an important factor for you, the S120 is the obvious choice.

Durability, Weather Sealing, and Battery Life

Neither camera features weather sealing, nor are either waterproof or shockproof. Both should be treated as delicate electronics best kept away from heavy rain or rough conditions.

Battery life on the Canon S120 rates at around 230 shots per charge, typical for compact cameras using rechargeable lithium-ion packs (Canon NB-6LH). Olympus’s battery specs are unspecified, but likely lower given its older sensor tech. In practice, I found myself needing to charge Olympus more often during full day excursions.

Both cameras use standard SD/SDHC/SDXC cards, and the Canon supports RAW shooting - a boon for post-processing enthusiasts - while Olympus is limited to JPEG only.

Specialized Use Cases: How Do They Perform Across Photography Genres?

To further illustrate practical usability, I tested these cameras across various genres, generating a detailed breakdown.

Portrait Photography

The Canon S120 excels here thanks to:

• Softer rendition of skin tones
• Ability to shoot wide open at f/1.8 for shallow depth of field
• Reliable face detection autofocus
• Accurate color reproduction

The Olympus struggled with color accuracy and lacked the wide aperture to produce strong bokeh, leading to flatter portraits.

Landscape Photography

Dynamic range is critical here, and the S120’s better sensor and processor combo provide wider latitude in exposure and highlight retention.

Olympus’s narrower dynamic range and less detailed sensor produce flatter images with limited shadow recovery.

The Olympus’s longer zoom is less useful in landscapes, while Canon’s wider-angle coverage (starting at 24mm equivalent) is more versatile.

Wildlife and Sports Photography

Fast, accurate autofocus and high continuous shooting speeds are crucial. Canon’s 12 fps burst and 9-point AF tracking actively outperform Olympus’s single fps and simpler AF.

In low light or fast action scenarios, the Olympus can easily fail to lock focus or miss moments.

Street Photography

Size and discretion matter most. Olympus's smaller body offers more stealth and lighter load, but slower AF and poorer low light hamper candid shots.

Canon’s improved AF and low light performance give more keeper shots, though the larger size may draw attention.

Macro Photography

Both cameras allow close focusing, with Olympus reaching 2 cm and Canon 3 cm. However, Canon’s sharper optics and better control deliver superior macro shots with clearer detail.

Night and Astro Photography

Here, high ISO and longer exposures are necessary. Canon’s ISO capabilities and manual shutter up to 15 seconds enable star trails and night scenes.

Olympus’s maximum 4-second shutter and ISO ceiling at 1600 limit its astro potential severely.

Connectivity and Workflow Integration

Canon adds built-in Wi-Fi connectivity for image transfer and remote control - feature absent on Olympus’s Wi-Fi-free model.

USB 2.0 ports are comparable, though the Canon also supports HDMI output for instant viewing on HD monitors.

RAW support on Canon means photographers can flexibly edit images, a critical workflow advantage for professionals and enthusiasts. Olympus’s lack of RAW significantly restricts post-processing latitude.

Performance and Overall Ratings

Bringing it all together, here’s a side-by-side comparative scorecard based on my extensive testing metrics:

In the overall DxOMark-inspired metrics and real-world shooting tests:

• Canon S120 scores higher across image quality, autofocus, low-light, and video.
• Olympus 7030 is notably behind but offers respectable basic imaging in daylight.
