Olympus E-M5 III vs. Olympus SZ-16 iHS: An Experienced Photographer’s In-Depth Comparison

Choosing the right camera can feel overwhelming, especially when options range from advanced mirrorless systems to compact superzooms. Having personally handled and evaluated over a thousand models in my 15+ years as a camera reviewer, I’m here to guide you through a detailed comparison between two Olympus offerings: the Olympus OM-D E-M5 III, a sophisticated Micro Four Thirds mirrorless camera released in 2019, and the Olympus SZ-16 iHS, a compact superzoom fixed-lens camera launched in 2013.

This is not just a specs showdown: I will break down the real-world usability, image quality, ergonomics, and feature sets based on actual field testing across photography genres. Whether you’re a serious enthusiast seeking precision tools or a casual snapshooter looking for versatility and convenience, this guide will point you in the right direction.

First Impressions and Handling: Size, Controls, and Build Quality

Before diving into image and performance metrics, I always assess the feel and physical design of a camera since ergonomics strongly impact the shooting experience. In side-by-side use:

The Olympus E-M5 III is a substantial upgrade in size and grip comfort compared to the ultra-compact SZ-16 iHS. The E-M5 III’s 125 x 85 x 50 mm body, weighing around 414g, offers a robust and weather-sealed chassis tailored for serious photography in diverse conditions. The grip is well-padded, and button placement is thoughtfully designed for quick manual operation.

In contrast, the SZ-16 iHS’s 108 x 70 x 40 mm size and slim profile make pocketability its defining attribute, but its smaller handhold and lighter weight (226g) mean extended handling can tire your fingers, particularly for more intricate controls.

Examining the top panels, the E-M5 III sports a rich control set: dual mode dials for aperture, shutter priority, manual modes, exposure compensation wheel, and customizable function buttons allow rapid manual adjustments on the fly. This mature interface reflects Olympus’s heritage of crafting gear for creative photographers.

Meanwhile, the SZ-16 iHS offers a minimalist layout tailored for simplicity and automatic operation - not much to tweak manually here. Its fixed lens and lack of dedicated manual dials make creative control more limited but easier for casual use.

Takeaway: If you value tactile control and durability, the E-M5 III’s professional ergonomics shine. For casual walking-around shooting where portability is key, the SZ-16 iHS is the better compact companion.

Sensor and Image Quality: Micro Four Thirds vs. Small-Sensor Compact

The heart of any camera is the sensor, which largely determines image quality, dynamic range, and low-light performance. The Olympus E-M5 III features a 20MP Four Thirds MOS sensor, measuring 17.4 x 13 mm with an active area of roughly 226.2 mm², while the SZ-16 iHS uses a smaller 1/2.3-inch CMOS sensor at 6.17 x 4.55 mm (about 28.07 mm²) with 16MP resolution.

This significant sensor size difference is immediately impactful when analyzing images. I tested both cameras using identical scenes under natural light conditions. The E-M5 III produced crisp, detailed shots with excellent color depth and a wide dynamic range, preserving highlights and shadows superbly. Noise levels stayed impressively low even at ISO 3200.

The SZ-16 iHS images, while decent in daylight, showed markedly more noise and less tonal gradation, especially in shadows or overexposed areas. Its smaller sensor and faster lens aperture limitations (F3.0-6.9 variable) restrict low light and depth of field control.

When zoomed in, the Four Thirds sensor’s advantage is unmistakable - better sharpness, finer detail rendering, and improved color fidelity.

LCD and Viewfinder: Composing and Reviewing Your Shots

Next, I evaluated the framing and review experience, closely tied to viewfinder and monitor design.

The E-M5 III boasts a 3-inch fully articulated touchscreen with 1040k dots, excellent resolution for previewing photos and a flexible tilt/swivel design that enables shooting from unconventional perspectives, including selfies - a boon for videographers and vloggers as well.

Its 2.36 million dot electronic viewfinder (EVF) offers 100% coverage and 0.68x magnification, delivering a clear, lag-free view for manual focusing and sunny-day composition.

Conversely, the SZ-16 iHS sports a 3-inch fixed TFT LCD with just 460k dots resolution. Tough to see fine detail outdoors, especially in bright light, and the lack of any EVF severely impacts stability and precision framing during handheld shooting.

For serious photography workflows, I rely heavily on an EVF paired with a sharp, responsive screen, putting the E-M5 III miles ahead here.

Autofocus System Analysis: Speed, Accuracy, and Tracking

Autofocus (AF) is one of the oft-underestimated performance pillars, especially for fast-paced genres like wildlife or sports.

The Olympus E-M5 III uses a hybrid AF system combining 121 phase-detect points with contrast detection, achieving rapid, precise focus locking plus face and eye detection - critical for portrait and candid shooting. During high-speed burst shooting, tracking remained reliable, capturing action crisply even under less-than-ideal lighting.

The SZ-16 iHS relies on a contrast-only AF with fewer focus points and slower response, suitable for casual snaps but prone to hunting in dimness or during rapid subject movement. Its autofocus capability is inconsistent for dynamic subjects like children or animals in motion.

Note: Neither camera supports advanced animal eye-AF as of 2019, limiting wildlife portrait precision somewhat in the E-M5 III, but its face detect excels.

Burst and Shutter Speed: Capturing the Decisive Moment

High-speed bursts and fast shutter options are essential for sports and wildlife photography.

• E-M5 III: Offers blazing continuous shooting up to 30 fps using electronic shutter and max mechanical shutter speed of 1/8000 second, supplemented by a silent shutter option up to 1/32000 second.
• SZ-16 iHS: Capable of just 2 fps burst, mechanical shutter tops out at 1/2000 second, no electronic silent shutter capability.

In practical terms, the E-M5 III allows seamless capture of fast action sequences, such as birds taking flight or athletes in competition, while the SZ-16 iHS can miss critical moments due to slower speed and buffer limits.

Lens Ecosystem: Flexibility and Creative Potential

One major distinction lies in lens compatibility.

• E-M5 III: Supports the Micro Four Thirds (MFT) mount, granting access to over 100 lenses from both Olympus, Panasonic, and third parties. Options range from ultra-wide fisheyes and fast prime portraits to super-telephoto wildlife zooms.
• SZ-16 iHS: Fixed lens with a massive 25-600mm equivalent zoom (24x optical zoom). This large zoom covering diverse focal lengths is great for travel convenience but sacrifices optical quality and aperture speed.

The flexibility to swap lenses on the E-M5 III empowers creative expression and optimized optics per scenario. The SZ-16 iHS is a straightforward, no-fuss solution for general shooting but limits photographic experimentation.

What About Image Stabilization?

Both cameras have image stabilization but differ in sophistication.

• E-M5 III features sensor-based 5-axis in-body image stabilization (IBIS), correcting pitch, yaw, roll, and X/Y shifts, allowing tack-sharp handheld shots at slow shutter speeds and smoother video.
• SZ-16 iHS offers sensor-shift stabilization, standard for compacts, but less effective in extreme focal lengths or low light.

During field tests, the E-M5 III produced a clear advantage, enabling handheld landscape and macro photography with less blur and camera shake artifacts.

Weather Sealing and Durability

The Olympus E-M5 III is weather sealed, resisting dust and moisture ingress – invaluable for outdoor, landscape, or travel shooters working in challenging conditions like rain or dusty environments.

The SZ-16 iHS has no such sealing and needs more cautious handling around water or dust exposure.

For demanding or professional use, the durability factor makes the E-M5 III an investment in reliability.

Battery Life and Storage Options

I always measure how long these cameras can last on a charge, important for travel and extended sessions.

• E-M5 III powered by BLN-1 battery, rated roughly 310 shots per charge in CIPA standards - decent for a mirrorless, though heavy video or electronic viewfinder use drains faster. Single SD UHS-II card slot.
• SZ-16 iHS uses the LI-50B battery, capable of around 220 shots, with single SD slot support.

Either camera can be supplemented with extra batteries to avoid mid-shoot outages.

Connectivity and Video Performance

The E-M5 III supports Wi-Fi and Bluetooth, allowing wireless image transfer and remote shoot control via a smartphone app - a modern convenience I appreciated during travel and urban shoots.

SZ-16 iHS lacks any wireless connectivity, necessitating cable transfers.

When it comes to video:

• E-M5 III shoots 4K UHD (4096×2160) at 24 fps, recording with H.264 codec and Linear PCM audio inputs; it has a mic port for external microphones, enhancing sound quality during interviews or vlogging.
• SZ-16 iHS maxes out at 720p HD video (1280x720) at 30fps with built-in microphones only, limiting situational use.

For those prioritizing video storytelling, the E-M5 III is the clear winner.
