Olympus SP-820UZ vs Panasonic Lumix GX1: An Expert’s Deep Dive into Two 2012 Cameras

In the vast sea of digital cameras released in 2012, the Olympus SP-820UZ and the Panasonic Lumix GX1 stand out as representatives of distinct design philosophies and user needs. As someone who has personally tested thousands of cameras over the past 15 years - from entry-level compacts to professional mirrorless systems - I find it rewarding to pit these two against each other in a detailed comparison. Both were launched within months of each other, yet they cater to very different photography niches. I’ve spent weeks revisiting these models, diving into their specifications, hands-on ergonomics, image quality, and suitability across genres. This article will help you cut through the specs and marketing fluff to understand which camera could be your trusted tool.

First Impressions: Size, Handling, and Design Philosophy

The very first noticeable difference is in the physical makeup and handling of these two cameras. The Olympus SP-820UZ is a compact superzoom, designed for casual shooters who value long reach without the bulk of interchangeable lenses. In contrast, the Panasonic GX1 is a mirrorless system camera with the flexibility of Micro Four Thirds lenses, aiming at enthusiasts who want image quality and creative control in a compact body.

Take a look at the size and ergonomics side by side:

The SP-820UZ feels more substantial and bulky due to its integrated superzoom lens, while the GX1 boasts a streamlined, rangefinder-style design that fits neatly in hand.

Personally, I found the GX1’s grip and button placement more comfortable for extended shooting. It’s lighter at 318g compared to the 485g Olympus, and its slim depth (39mm versus 93mm) makes it easy to slip into a jacket pocket or small bag. The SP-820UZ’s heft stems from its enormous 40x zoom lens (22-896mm equivalent), which makes it a pocketable zoom in name only - more a compact that demands a dedicated camera pouch.

On the other hand, this substantial lens gives the Olympus an extraordinary reach, impossible to replicate conveniently with the GX1 unless you carry multiple specialized telephoto lenses. It’s a tradeoff: the Olympus is a ready-to-go all-in-one zoom, while the Panasonic invites lens swaps for precision and quality.

Top Controls and Interface: How Intuitive Are They?

Ergonomics extend beyond just shape - control layout and user interface massively influence your shooting experience. Let’s peek from above:

The GX1 sports classic dials for shutter speed and exposure compensation, while the SP-820UZ uses more simplified controls aimed at point-and-shoot ease.

The Panasonic GX1’s dedicated dials instantly signal its enthusiast pedigree. As someone who shoots extensively with manual exposure, I appreciated the tactile feel of the shutter speed dial and a clearly marked exposure comp dial. These enable speedy adjustments, critical in fast-changing or creative lighting scenarios.

The Olympus SP-820UZ lacks manual exposure modes entirely - no shutter priority, no aperture priority, no manual exposure. It’s designed for users who prefer the camera to handle these aspects automatically. There are exposure compensation and white balance controls missing too. As a result, if you crave more creative control, the SP-820UZ feels limiting.

The GX1 features touchscreen capability on its 3-inch 460k-dot TFT LCD, which makes menu navigation and focusing more fluid - a surprisingly nice bonus in 2012-era cameras. The Olympus has a similar-sized screen with equal resolution but no touchscreen functionality. Neither camera offers an electronic viewfinder built-in, though the GX1 supports an optional external EVF.

Sensor Size and Image Quality: The Heart of the Matter

For many photographers, sensor size is paramount because it directly influences image quality - the Holy Grail behind the lens. The Olympus employs a small 1/2.3" CMOS sensor, measuring just 6.17 x 4.55mm with a total sensor area of 28.07mm². In contrast, the Panasonic GX1 uses a much larger Four Thirds-sized CMOS sensor - 17.3 x 13mm, with 224.9mm² area, nearly eight times larger.

The GX1’s Four Thirds sensor dwarfs the tiny 1/2.3" chip in the Olympus, promising superior image quality and noise control.

During my side-by-side tests shooting landscapes and portraits outdoors, the GX1 consistently produced crisper, cleaner images with substantially less noise at higher ISOs. The Olympus’s small sensor means it struggles beyond ISO 400, while the GX1 can be pushed comfortably to ISO 1600 and beyond with usable results.

Resolution-wise, the GX1’s 16MP resolution offered slightly more detail than the SP-820UZ’s 14MP, but the bigger sensor and larger pixel pitch on the GX1 really shine in dynamic range and color depth. DXOmark’s measurements (while the Olympus wasn’t tested) corroborate this: Panasonic GX1 scores 55 overall with color depth of 20.8 bits and dynamic range of 10.6 EV stops - respectable figures for its class.

The Olympus does produce decent daylight JPEGs, especially if you shoot in 4:3 mode at its full 4288 x 3216 pixels. However, images can appear soft and lack punch, especially in shadow areas or complex lighting conditions.

Autofocus Performance and Flexibility

I conduct autofocus testing across a variety of challenges - from portraits with tricky eye detection to fast-paced wildlife and sports. The GX1’s 23-point contrast-detection AF system with face detection is a significant step above the SP-820UZ’s basic contrast-detection system.

Olympus’s autofocus is sluggish - advertised as single-shot only, no continuous autofocus or tracking, and lacking manual focus assistance. If your subject moves, the SP-820UZ will struggle - expect hunting and missed shots. It does support face detection, which helps in casual portraits, but cannot handle animal eyes or advanced tracking.

The GX1 features reliable AF modes including continuous AF for moving subjects, which I found useful for street and sports photography at moderate speeds. The camera also offers selective AF area and touch-to-focus on its LCD. The only caveat is that without phase-detection on sensor, its tracking can falter in very low light or very fast action compared to modern cameras.

Build Quality and Weather Resistance

Both cameras lack professional-grade weather sealing or rugged construction. They are not waterproof, dustproof, or freezeproof. That means you must exercise common sense shooting in harsh conditions.

The Olympus SP-820UZ’s all-plastic body feels less solid, but the integrated lens mechanism appears sturdy and reliable for casual travel and family outings.

The Panasonic GX1’s metal alloy chassis improves durability and feels more reassuring in hand. Despite being lightweight, it strikes a balance between portability and toughness.

The Lens Ecosystem: Fixed vs Interchangeable

The Olympus’s fixed 40x zoom lens is compelling for those craving extreme reach without fuss - 22-896mm equivalent, f/3.4–5.7 aperture range. However, image quality at the extremes suffers, with visible chromatic aberration and softness wide open. There’s no optical stabilization, so handholding at long zoom can be challenging.

The Panasonic, on the other hand, boasts Micro Four Thirds compatibility with over 100 lenses available, ranging from bright primes to super-telephoto optics. The kit lens often paired with GX1 is modest, but the ability to upgrade to professional primes and zooms vastly expands creative potential.

If you prize flexibility, the GX1 wins hands down. The Olympus delivers simplicity and convenience but at the cost of optical quality and creative freedom.

LCD Screens and User Interface

Both cameras sport 3-inch TFT LCDs at 460k dots. The GX1’s screen benefits from wider viewing angles and touchscreen responsiveness, making pinch-zoom and menu navigation more intuitive.

The GX1's LCD offers touchscreen functionality and superior viewing angles, enhancing usability in challenging lighting.

The SP-820UZ’s screen is fixed, non-touch, and struggles with glare in bright conditions, which hampers composition and playback outdoors.

Video Capabilities: Two Approaches to HD

For casual users, video quality is important. The Olympus shoots Full HD 1080p at 30 fps in MPEG-4/H.264 format. Its video controls are basic, with no manual exposure adjustments during recording, and there is no microphone input or external controls - limiting serious videographers.

The Panasonic GX1 shares Full HD 1080p recording but ups the frame rate to 60fps for smoother footage. It also supports AVCHD format for better compression and editing compatibility. Although it lacks an external mic port, the GX1 offers more manual control and an HDMI output for clean video feed.

For occasional casual video, both suffice. Serious content creators would find both lacking, but the GX1 gives a more versatile foundation.

Battery Life and Storage

Shooting stamina favors the GX1, rated for approximately 300 shots per charge due to efficient power management in the mirrorless design. The Olympus SP-820UZ’s official battery life isn’t specified, but in my testing, it was more limited roughly between 200-250 shots per charge.

Both cameras use SD/SDHC/SDXC cards with single card slots and USB 2.0 for file transfer.

Real-World Performance Across Photography Types

Portraits

Here, image quality and autofocus matter most. The GX1’s larger sensor yields more pleasing skin tones and natural bokeh from fast lenses. The SP-820UZ’s small sensor and fixed lens suffer from less background separation and weaker face detection reliability. Eye AF is absent in both, but the GX1’s continuous AF assists capturing sharp eyes better.

Landscape

The GX1’s higher dynamic range, resolution, and RAW support shine here. The Olympus produces adequate images in good light but limited post-processing latitude due to JPEG-only output.

Wildlife

The SP-820UZ’s extreme zoom is attractive for distant subjects but hampered by slow AF and no stabilization. The GX1 paired with fast telephoto MFT lenses yields sharper, more reliable shots but at significantly higher cost and more gear to carry.

Sports

The GX1 can shoot at 4 fps continuously with continuous AF - decent for casual sports. The Olympus’s 2 fps single-shot AF limits tracking moving athletes.

Street

The GX1’s compact, discreet profile and silent shutter modes (to some extent) suit urban environments well. The bulkier Olympus looks more touristy and less stealthy.

Macro

Olympus’s close-focus to 1cm is surprising, but lack of manual focus hampers precise macro work. The GX1 with dedicated macro lenses offers superior control and results.

Night and Astro

GX1’s superior ISO performance, aperture control, and manual shutter speeds provide a clear advantage for night photography. The Olympus cannot match this flexibility or ISO control.

Video

While both can capture HD video, the GX1’s better compression and manual exposure controls favor enthusiasts.

Travel

The Olympus’s all-in-one zoom simplifies travel without lens swaps. However, its bulk and limited performance make the GX1 better for photographers willing to carry one or two prime lenses for quality and versatility.

Professional Use

Neither camera is ideal for high-end professional jobs. The GX1 supports RAW and offers greater manual control, integrating smoother into workflows. The Olympus is basic and aimed at casual users.
