Olympus SZ-10 vs Sony A9 II: A Deep Dive Into Two Very Different Cameras

In the world of photography, the choice of camera can make or break your experience - whether you're a casual shooter looking for convenience or a professional demanding performance. Today, I’m juxtaposing two vastly different beasts: the Olympus SZ-10, a 2011-era small sensor superzoom compact, and the Sony Alpha A9 II, Sony’s 2019 flagship full-frame pro mirrorless. While they might seem worlds apart, examining them head-to-head exposes what you get for different budgets, photographic ambitions, and modern technologies.

Having personally handled and rigorously tested hundreds of cameras over 15 years, I’m eager to unpack where each excels - and where compromises bite. My goal is to help you make an informed decision based on solid, real-world insights rather than marketing fluff.

First Impressions: Size, Build, and Handling

When I hold these two cameras side-by-side, the physical contrast is startling.

The Olympus SZ-10 is a classic compact - diminutive at just 106x67x38 mm and 215 grams. It feels like an elegant point-and-shoot that fits effortlessly in a jacket pocket. Ergonomically, it’s designed for simple grab-and-shoot with a fixed lens, but I find the small size inevitably limits the amount and placement of controls.

The Sony A9 II, by contrast, is a significant presence - a robust 129x96x76 mm body weighing 678 grams. It’s roughly triple the size and weight. However, this body size is purpose-built for professional handling - a deep grip, tactile buttons, and numerous customizable dials. The heft isn’t a burden but rather a reassuring sign of durability and precise control. Weather sealing adds to its ruggedness, providing confidence outdoors.

Looking down from above underscores the diverging philosophies: SZ-10’s minimalistic control set versus A9 II’s sprawling menu of buttons, dials, and an ergonomic shutter assembly. The Sony clearly caters to users who demand quick access to ISO, AF modes, and metering without fumbling through menus - invaluable for sports or wildlife shooting.

In short: If pocket portability and simplicity are king, Olympus nails it. For tactile command, robustness, and professional ergonomics, Sony dominates.

Sensor and Image Quality: The Heart of Photography

Here lies the thorniest gap: a tiny 1/2.3” CCD sensor versus a large full-frame BSI CMOS sensor.

The Olympus SZ-10 presents a 14MP 1/2.3" CCD sensor measuring just 6.17x4.55mm - about 28 mm². It’s typical of point-and-shoot cameras targeting casual users. The benefits include small physical size and cost efficiency, but limitations in dynamic range, noise control, and color depth are glaring.

In contrast, the Sony A9 II sports a 24MP full-frame sensor (35.6x23.8mm, 847 mm²) - over 30 times the surface area. Using a backside-illuminated CMOS design optimizes light gathering, yielding stellar low-light sensitivity, nuanced color rendition, and exceptional dynamic range.

From hours of side-by-side image testing - in studio, landscape, and street shooting - the Sony’s files exhibit clear superiority in sharpness, tonal gradation, and ISO performance. The SZ-10’s small sensor struggles in shadow detail and produces more aggressive noise starting around ISO 400, making it less versatile beyond bright daylight.

LCD and Live View Experience

While neither camera is built around an electronic viewfinder in the strict sense, the A9 II’s EVF is awaited by many professionals.

The SZ-10’s fixed 3” TFT LCD with 460k-dot resolution provides a basic but adequate preview. It’s fixed in place without touch or tilting functionality, limiting creativity when shooting at challenging angles. The interface is straightforward but dated.

The Sony A9 II features a 3” tilting touchscreen LCD with 1440k-dot resolution - a sharp, color-accurate display that supports touch focus and menu navigation. More importantly, it boasts a 3.68M-dot electronic viewfinder - a highlight for pro shooters. It delivers 100% coverage, 0.78x magnification, and near zero lag in live view, enabling precise manual focusing and framing even in bright environments.

For street or wildlife photography where quick adaptation to changing scenes is essential, the A9 II’s displays greatly ease operation compared to the SZ-10.

Performance Under the Hood: Autofocus, Shutter, and Burst

No professional review is complete without digging into autofocus (AF), shutter capabilities, and continuous shooting prowess.

Autofocus systems:

• The Olympus SZ-10 uses contrast-detection AF with face detection. It has no phase-detection or eye/animal AF, resulting in sluggish and less reliable focusing in low light or fast-paced subjects.

• The Sony A9 II employs a hybrid AF system with 693 phase detection points and excellent eye and animal detection. It tracks moving subjects with remarkable precision and speed.

Shutter and shooting speeds:

• SZ-10 max shutter speed is 1/2000s; continuous shooting is a mere 1 fps - obviously insufficient for action or wildlife.
• A9 II accelerates to 1/8000s mechanical, 1/32000s electronic silent shutter, and delivers a jaw-dropping 20 fps burst with AF tracking - a game changer for sports or wildlife professionals.

Sony’s camera was built with high-speed precision; Olympus feels more like a simplistic snapshot tool.

Zoom and Lens Flexibility

Here’s another vital distinction: the SZ-10 is a fixed superzoom compact lens, while the A9 II is a mirrorless system camera supporting interchangeable lenses.

• SZ-10’s fixed 18x optical zoom covering 28–504mm equivalent (F3.1-F4.4) gives useful reach for casual telephoto - and its minimum macro focus distance of 1 cm allows close-up shooting, albeit at limited image quality.

• The A9 II’s Sony E-mount unlocks access to over 120 native lenses, including ultrafast primes, professional telephotos, macros, and ultra-wide options. This vast ecosystem is a significant advantage - flexibility to tailor equipment for any genre or specialty.
