Olympus SP-800 UZ vs Panasonic Lumix GH5: Which Camera Fits Your Photography Ambitions?

Choosing the right camera can be a daunting task, especially when the models belong to entirely different classes and eras in photography technology. Today, I’ll provide you with an in-depth, hands-on comparison between the Olympus SP-800 UZ, a compact superzoom from 2010, and the Panasonic Lumix GH5, a professional mirrorless workhorse launched in 2017. Each represents very distinct philosophies - the convenience-oriented all-in-one zoom compact versus a highly capable Micro Four Thirds system camera beloved by professionals and enthusiasts alike.

Drawing on my extensive experience testing cameras across genres, I’ll break down their specifications, real-world performance, and suitability for various photography disciplines to help you decide which best suits your needs.

A Tale of Two Bodies: Compact Superzoom vs Professional Mirrorless

Let’s start by looking at their physical design and ergonomics - two aspects that heavily influence how you’ll actually use the camera day to day.

• Olympus SP-800 UZ: This is a compact, bridge-style superzoom camera. Its fixed lens covers an expansive 28-840mm focal range (30x zoom), all in a relatively small body weighing just 455g. Dimensions are 110x90x91mm, making it pocketable for travel yet with a solid grip.

• Panasonic GH5: In direct contrast, the GH5 is a larger, SLR-style mirrorless camera weighing 725g with dimensions of 139x98x87mm. It offers an interchangeable lens mount (Micro Four Thirds) with access to over 100 native lenses, providing true flexibility.

Ergonomic notes from my testing:

• The SP-800 UZ is straightforward, with a simple layout tailored for casual shooting. Its compact size makes it very portable but sacrifices advanced controls.

• The GH5 offers a robust, weather-sealed body with extensive physical buttons, dials, and customizable controls. It fits more naturally into professional workflows but has a learning curve for newcomers.

For a side-by-side look at their top designs and control layouts:

Sensor Technology and Image Quality: The Heart of the Matter

A dramatic difference lies in the sensor technology and resultant image quality - a key determinant for serious photographers.

• Olympus SP-800 UZ: Features a 1/2.3" CCD sensor with 14 megapixels (4288x3216 max resolution). The sensor area is only 28.07mm². CCDs generally offer decent color but lag behind modern CMOS technology in noise handling and dynamic range. Native ISO tops out at 3200 but practical use beyond 400-800 ISO is noisy.

• Panasonic GH5: Equipped with a Four Thirds-sized CMOS sensor measuring 17.3x13mm with 20MP resolution (5184x3888). The sensor area is 224.90mm² - nearly eight times larger than the SP-800 UZ’s. This size difference grants the GH5 superior image detail, dynamic range, and low-light performance. It supports native ISO from 200 to 25,600, with excellent noise control.

Drawing from my side-by-side image testing, here’s a sensor size comparison illustrating the magnitude of this gap:

What does this mean in practice?

• The GH5’s sensor collects substantially more light, resulting in better sharpness, richer colors, and cleaner high-ISO images. It shines in low-light scenes, night and astro photography, and professional portraiture demanding skin tone fidelity.

• The SP-800 UZ’s small sensor and CCD architecture limit dynamic range and introduce noise at higher ISO, suitable for well-lit daylight or casual photography but less capable under challenging conditions.

User Interface and Display: Check Your Shooting Window

The clarity of your viewfinder and display aids immensely in composition and focus confirmation.

• The SP-800 UZ offers a fixed 3” LCD screen with 230k dots resolution and no electronic or optical viewfinder. This limits its utility in bright sunlight or fast pacing situations. The LCD is fixed, which restricts shooting angles.

• The GH5 features a 3.2” fully articulated touchscreen LCD with a crispy 1.62 million dots resolution. It also boasts a professional-grade electronic viewfinder (EVF) with 3.68 million dots, 100% coverage, and 0.76x magnification, allowing precise framing and confirmation in any light.

Seeing them side by side:

The GH5’s articulation combined with touchscreen controls enables more flexible shooting positions for, say, macro or street photography. The SP-800’s single fixed screen is more limiting, but since it has no viewfinder, you rely entirely on this display.

Autofocus and Speed: Capturing the Decisive Moment

For dynamic photography - sports, wildlife, street - you want responsive, accurate autofocus and good shooting speeds.

• SP-800 UZ: Uses contrast-detection autofocus with 143 focus points, no manual focus, and no continuous autofocus. Its burst speed tops out at 10 fps, but buffer depths and focus lockups hamper extended shooting bursts.

• GH5: Features a highly sophisticated autofocus with 225 contrast-detection points, plus face detection, touch focus, selective, and continuous AF modes, including reliable tracking for moving subjects. It offers 12 fps continuous shooting with full AF-C for action sequences.

In my tests tracking birds and athletes, GH5’s autofocus system proved consistently faster and more accurate. The SP-800 UZ lags behind, suitable mainly for static or slow-moving subjects.

Lens Ecosystem and Versatility: The Freedom to Create

Your creative potential hinges on what lenses you can pair with your camera.

• The SP-800 UZ’s fixed lens covers 28-840mm focal length (30x zoom) with an aperture range of f/2.8-5.6, which is impressive for a compact. It offers super-telephoto reach and surprisingly close macro focusing down to 1cm. However, you’re locked into this one lens with trade-offs in optical quality and speed vs. interchangeable lenses.

• The Panasonic GH5’s Micro Four Thirds mount provides access to a vast array of optics from Panasonic, Olympus, Sigma, Tamron, and others. This includes prime lenses, ultra-wide angles, specialty macro lenses, fast apertures for portraits, and super telephotos for wildlife.

This vast lens choice makes the GH5 an incredibly versatile tool - whether you want pristine landscapes, fast sports lenses, or creative portraits with shallow depth of field.

Build Quality and Environmental Resistance

• The SP-800 UZ is compact but lacks weather sealing or ruggedness features. It’s best for casual use in fair weather and protected environments.

• The Panasonic GH5 has a fully magnesium alloy body with sealing against dust and splash, suitable for professional outdoor use, including light rain or dusty locations.

This robustness adds peace of mind for professionals shooting in diverse conditions.

Battery Life and Storage Capabilities

• SP-800 UZ uses the Li-50B battery but lacks published battery life ratings. From personal experience, expect around 300 shots per charge with no power-saving features.

• GH5 uses a larger battery pack rated at approximately 410 shots per charge, which is solid given its powerful processor and large EVF usage. It also supports dual SD card slots with UHS-II compatibility, beneficial for overflow or backup recording.

Dual card slots, faster storage, and longer battery life make the GH5 far more dependable for professional workflows and extended shooting sessions.
