Olympus SZ-12 vs Sony HX7V: A Hands-On Comparison for the Discerning Photographer

When choosing a compact superzoom camera, there’s a fine balance between versatility, image quality, and ergonomics. Today, I’ll share my detailed, firsthand analysis of two compact contenders that have garnered attention in the past decade: the Olympus SZ-12 and Sony Cyber-shot DSC-HX7V (HX7V). Both were designed as travel-friendly, pocket-ready superzooms but come with unique feature sets that cater to distinct photography styles.

Having put them through numerous test shoots - including landscapes, portraits, wildlife, and casual travel snaps - I’m confident this comparison will help enthusiasts and professionals alike make an informed decision. Let’s dive into their physical attributes before getting technical.

Small Cameras, Big Ambitions: Body Design and Handling

Both cameras sport compact bodies, but the way they feel during extended use varies quite a bit. The Olympus SZ-12 measures 106 x 69 x 40 mm and weighs about 226 g, sitting solidly in the pocket camera category. The Sony HX7V is slightly more petite - 102 x 58 x 29 mm, 208 g - closer to a typical compact. To get a better sense of scale and handling, see below.

The SZ-12’s larger depth (40 mm versus 29 mm) gives it a chunkier grip area, which I found more comfortable for longer sessions or when shooting at telephoto ranges. The Sony, while lighter and sleeker, feels a bit too slim for users with larger hands, potentially leading to grip fatigue during burst shooting or extended movie recording.

Looking at control layouts from the top down also reveals their ergonomic priorities.

The Olympus provides straightforward controls without dedicated dials for shutter or aperture priority modes, as both cameras omit these manual exposure options. However, its zoom rocker and shutter placement felt more intuitive during my rapid-response shooting, a crucial factor when chasing wildlife or street moments.

The Sony HX7V, meanwhile, packs in more sophistication with a dedicated macro button and quick access to white balance settings - which can come in handy for travel and landscape photographers. Its textured grip is less pronounced than Olympus’s but the layout is streamlined to minimize accidental presses.

Sensor and Image Quality: The Heart of the Matter

Both use the same sensor size - 1/2.3" (6.17 x 4.55 mm sensor area), meaning their base optical potential will have constraints typical of smaller compact sensors. Olympus employs a 14MP CCD sensor, whereas Sony opts for a higher resolution 16MP BSI CMOS sensor.

This difference in sensor technology is profound. CCD sensors like Olympus’s tend to have excellent color reproduction but generally struggle with noise at higher ISOs and slower readout speeds. The Sony’s BSI CMOS, with backside illumination, provides improved sensitivity and lower noise - particularly beneficial in low light or night photography.

To better understand how these translate into usage, I ran comparative tests shooting ISO ranges from 80 (Olympus) / 125 (Sony) up to their max values (1600 for Olympus, 3200 for Sony). The Sony’s images retained more detail in shadows and preserved color fidelity above ISO 400 - very noticeable in dim interiors or dusk landscapes.

Speaking of resolution, Olympus outputs images at 4288 × 3216 (14MP), while Sony pushes 4608 × 3456 (16MP). While the difference may seem nominal, Sony’s slightly higher megapixel count allows for more cropping flexibility without losing sharpness, an advantage for wildlife or sports photographers needing tight framing.

Rear Screen and Interface: The Photographer’s Window

Both cameras feature fixed 3-inch displays, but there’s a notable gap in resolution quality and user interface responsiveness.

Olympus’s 460k-dot TFT LCD is serviceable but feels grainy and dim under bright conditions, which can hinder precise composition or focus confirmation in the outdoors. The Sony HX7V boasts a 921k-dot Xtra Fine LCD, delivering crisp detail and higher brightness - making it easier to review shots, even under direct sunlight.

Neither camera has a touchscreen, which is not surprising given their 2011-2012 release dates. Still, Sony’s UI navigates faster and supports live view autofocus more responsively, making it smoother for quick adjustments.

Autofocus and Shooting Speed: Catching the Moment

Speed and accuracy in autofocus can make or break your ability to capture decisive moments, especially for portraits, wildlife, and sports.

The Olympus SZ-12 uses contrast-detection autofocus with face detection and multi-area focus. Notably, it offers active tracking autofocus, allowing the camera to lock on and follow a subject within the frame. In real use, though, I found its focus hunting on moving subjects a bit slow, especially at the extreme telephoto end (600mm equivalent). Burst rate is a humble 1 fps, limiting its suitability for fast action or wildlife.

Sony’s HX7V also uses contrast-detection AF but lacks face or tracking detection. Instead, it features a 9-point AF system with center-weighted focus metering. Although no face detection may seem like a drawback, the camera’s continuous shooting speed of 10 fps (quite remarkable for the class) compensates by increasing your odds of nailing a shot in motion. Autofocus lock was quicker on static or slow subjects; however, tracking fast-moving wildlife was less reliable.

Image Stabilization: Steady Hands Win

The Olympus SZ-12 integrates sensor-shift (mechanical) image stabilization, which worked very effectively at full zoom lengths during my tests - handheld shots at 600 mm often delivered usable results without resorting to higher ISOs.

Sony HX7V relies on optical image stabilization (likely lens shift), which also proved effective but showed slight wobble at the longest zoom (250 mm) - understandably so, given the shorter focal range and form factor constraints. Still, both cameras can significantly reduce blur from handshake, a must-have feature for telephoto shooting in compact bodies.

Lens Characteristics and Zoom Reach: What’s Your Focal Playground?

Zoom versatility is a major draw for compact superzooms, and here the Olympus SZ-12 offers a massive 25-600mm (24x optical zoom) lens with an aperture range from F3.0 to F6.9.

By contrast, the Sony HX7V sports a 25-250mm (10x optical zoom) lens, slightly slower starting at F3.5 and narrowing to F5.5 at telephoto.

This difference has practical implications. Olympus’s extensive reach is enticing for wildlife photographers or travel shooters who want to capture distant subjects without carrying multiple lenses. The trade-off: Olympus’s lens speed drops noticeably at the long end, demanding steadier grip or higher ISO.

Sony’s shorter zoom is better suited to general-purpose shooting with a more manageable size and generally sharper mid-range optics. Its wider aperture at shorter focal lengths also benefits low-light indoor and street photography.

Video Capabilities: More than Just Stills

Video recording can often be an overlooked but important dimension in compact cameras.

The Olympus SZ-12 records 1280 x 720p HD at 30 fps, saving files in MPEG-4 and H.264 formats. It's very basic - no 1080p mode, no advanced audio inputs, and no 4K or high frame rates.

The Sony HX7V, however, boasts full 1920 x 1080p (1080p) at 60 fps recording, a clear step up, with formats including AVCHD and MPEG-4. The better sensor and processor (BIONZ) allow for cleaner compression and detail retention. While neither camera supports external microphones or advanced video features, Sony’s smoother footage and higher framerate make it much better suited to casual video content creation.

Battery Life and Storage: Staying Power on the Go

The Olympus SZ-12 uses a rechargeable LI-50B battery pack, rated for approximately 220 shots per charge, while the Sony HX7V employs the NP-BG1 battery with unspecified but generally similar endurance. Based on my tests, Sony’s power efficiency, coupled with its lower weight, makes it a slightly better companion for long travel days.

Storage is straightforward in both - each supports SD, SDHC, and SDXC cards. Sony also uniquely supports Memory Stick formats, providing flexibility for owners of Sony accessories. Neither camera offers dual slots or built-in wireless file transfer; though Sony boasts “Eye-Fi Connected” for wireless card compatibility, which enables basic Wi-Fi transfers when paired with specific SD cards.

Weather Sealing and Durability: Toughness Where It Counts

Neither the Olympus SZ-12 nor the Sony HX7V offers official weather sealing or ruggedness such as shockproof or freezeproof construction. Therefore, both require careful handling around moisture or dust. Olympus has some history in rugged models, but this SZ-12 is strictly a compact consumer camera.
