Olympus SZ-30MR vs Sony A9 II: A Deep Dive into Two Cameras from Opposite Ends of the Spectrum

Choosing the right camera can be a daunting task, especially when facing cameras as different in ambition and capability as the Olympus SZ-30MR and the Sony A9 II. As someone who has personally tested thousands of cameras across all photography genres, I’m here to break down what separates these two models - and who each is truly built for. This comparison isn’t just about specs on paper, but about real-world performance and what you actually get in your hands.

Let’s start by setting the stage with a physical look at these devices.

Sizing Up The Cameras: Ergonomics and Portability

At a glance, you can see just how radically different these cameras are in terms of size and design philosophy.

• Olympus SZ-30MR: This is a compact superzoom, designed with portability front and center. Measuring just 106 x 69 x 40 mm and weighing a light 226 grams, it fits comfortably in a coat pocket or small camera bag. Its plastic build keeps it light but doesn’t offer rugged durability.

• Sony A9 II: A professional-grade, SLR-style mirrorless with a robust magnesium alloy chassis. At 129 x 96 x 76 mm and 678 grams, it demands a dedicated camera bag and two hands for comfortable handling during prolonged shoots.

For travel and casual use, the SZ-30MR’s compactness is a major plus. However, if you’re serious about professional work, the A9 II’s form factor supports extended sessions with better grip and control.

Design and Controls: Intuitive Layout vs Simplified Operation

Examining the top views reveals a stark contrast in user interface.

• The SZ-30MR has a very simplified control scheme, lacking manual exposure dials or buttons. It features a shutter button, zoom rocker, basic mode dial, and a small OLED panel showing minimal info - ideal for point-and-shoot convenience.

• The A9 II offers a full set of dedicated dials for shutter speed, exposure compensation, and programmable buttons. The top LCD screen is high resolution, giving quick access to detailed shooting parameters - essential for pros needing rapid workflow transitions mid-shoot.

I found that while the SZ-30MR is easy to pick up for beginners or casual users, it falls short for photographers who like to tweak settings manually on the fly. The A9 II excels here with expert-level customization and ergonomic refinement.

Sensor Technology & Image Quality: Small Sensor Superzoom vs Pro Full Frame

The heart of every camera is its sensor, and here’s where these two diverge most dramatically.

Olympus SZ-30MR:

• 1/2.3" CMOS sensor (6.17 x 4.55 mm) with 16 megapixels.
• Sensor area: 28.07 mm² - typical for compact cameras.
• Small sensor results in lower dynamic range, higher noise in low light, and limited depth-of-field control.
• Max ISO 3200, fixed optical low-pass filter (antialias filter) slightly softens images.

Sony A9 II:

• Full-frame 35.6 x 23.8 mm back-illuminated CMOS sensor with 24.2 megapixels.
• Sensor area 847.2 mm² - nearly 30 times larger than the Olympus.
• High dynamic range, excellent high ISO performance (native up to ISO 51200, expanded to 204800).
• Equipped with an anti-aliasing filter for sharp, detailed images with minimal moiré.

In hands-on shooting, the Olympus is sufficient for daylight snaps and casual prints but won’t satisfy users needing refined color, detail, or clean shadows. The A9 II’s sensor produces professional-grade images that stand up to large prints and extensive post-processing.

LCD Screen and Interface Usability

Screen technology affects composition and reviewing images:

• SZ-30MR offers a fixed 3-inch TFT LCD with 460k dots. It is bright enough in shade but struggles under direct sunlight, and has no touchscreen or articulation.

• A9 II features a 3-inch tilting touchscreen LCD with a much denser 1.44 million dots, enabling precise focus adjustments and menu navigation via touch. This is invaluable in fast-paced professional environments.

The difference here impacts workflow efficiency: the A9 II makes image inspection and focus confirmation easier, while the SZ-30MR’s screen is strictly basic.

Focusing Systems and Speed: Phase-detection vs Simple Contrast

The Olympus SZ-30MR and Sony A9 II deliver vastly different autofocus experiences:

• SZ-30MR relies on contrast-detection autofocus with face detection. It has limited AF points, lacks continuous AF or manual focusing, and its AF speed tops out at about 2 fps burst with noticeable lag.

• A9 II is renowned for its hybrid autofocus system combining 693 phase detection points that cover 93% of the frame with 425 contrast detection points. It supports AF-C tracking, eye AF for humans and animals, and continuous shooting at up to 20 fps with blackout-free viewing.

In my field tests, the A9 II routinely nailed fast-moving wildlife and athletes with precision, a feat impossible for the SZ-30MR’s modest system.

Build Quality, Weather Sealing, and Durability

While neither camera is waterproof, build quality clearly favors the Sony:

• The A9 II has a sealed body resistant to dust and moisture, tested in demanding professional scenarios. Its magnesium alloy shell feels solid under stress, ideal for travel to adverse conditions.

• The SZ-30MR lacks any weather sealing, uses lighter plastics, and is more susceptible to damage or malfunction in harsh environments.

If you plan to shoot outdoors in varied climates or professional gigs, the A9 II offers peace of mind unmatched by the Olympus.

Lens Ecosystem and Versatility

The Olympus SZ-30MR has a fixed zoom lens ranging from 25-600 mm (equivalent), with a max aperture of f/3.0-6.9 - impressive on paper but with optical compromises due to the extremely long focal range.

The Sony A9 II, however, uses the Sony E-mount system with over 120 native lenses. That includes fast primes, macro lenses, specialist optics, and professional telephotos. This flexible ecosystem lets photographers tailor their gear to any genre or style.

If upgrading your photography is in mind, Sony’s system offers unmatched growth potential.

Battery Life and Storage Options

The tools for long sessions differ vastly:

• Olympus SZ-30MR uses a LI-50B battery delivering about 220 shots per charge. It has a single SD card slot compatible with SD/SDHC/SDXC.

• Sony A9 II boasts several advantages: a more powerful NP-FZ100 battery rated for around 690 shots, dual SD card slots supporting UHS-II for fast write speeds and backups.

In practical terms, the Sony enables full-day shooting without swapping batteries or worrying about storage space - essential for weddings, sports events, or wildlife safaris.

Connectivity and Wireless Features

Both cameras provide basic connectivity but to very different ends:

• The SZ-30MR supports Eye-Fi cards (Wi-Fi enabled SD cards), HDMI output, and USB 2.0, offering limited wireless convenience.

• The A9 II comes with built-in Wi-Fi, Bluetooth, NFC, USB 3.1 Gen 1, full-size HDMI, and external microphone and headphone jacks, integrating seamlessly with professional workflows and remote control setups.

Wireless functionality on the Sony is tailored for professionals needing instant image transfer and remote operation - something absent from the Olympus.

Video Capabilities: Basic vs Professional-Grade

Here the difference is like night and day:

• The Olympus SZ-30MR records 1080p full HD video at 30 fps using simple MPEG-4 compression with no external microphone support or advanced video tools.

• The Sony A9 II can capture 4K UHD video at 30 fps internally with full pixel readout and no pixel binning. It supports 100 Mbps XAVC-S codec for higher quality, plus external audio input/output for professional sound.

If video is a key part of your creative output, the Sony stands clearly ahead.
