Panasonic Lumix DC-G100 vs. DMC-ZS30: An Expert Comparison for Photography Enthusiasts
Choosing the right camera is never a straightforward task - especially when comparing two Panasonic models aimed at very different users and use cases: the Panasonic Lumix DC-G100, a modern entry-level mirrorless with Micro Four Thirds versatility, and the Panasonic Lumix DMC-ZS30 (also known as DMC-TZ40), a small-sensor superzoom compact from 2013.
I’ve put both models through their paces extensively to help you nail down which fits your photography ambitions, style, and budget in 2024. This article covers everything from sensor technology to ergonomics and practical use across genres like portrait, landscape, wildlife, and travel photography.
A Tale of Two Cameras: Understanding Their Core Differences
At first glance, these cameras serve very different purposes:
-
The G100 is built on a much newer, larger Micro Four Thirds sensor (17.3x13 mm vs. the ZS30’s tiny 1/2.3" sensor of 6.17x4.55 mm) offering higher resolution, better low-light shootability, and interchangeable lenses.
-
The ZS30 is a compact superzoom with an integrated 24-480mm equivalent lens designed for portability and reach, suited for casual shooters who want an all-in-one camera.
Let’s break down how those distinctions affect performance in practical terms.
Sensor Technology and Image Quality: Why Size Matters
The sensor is the heart of any camera. It shapes image quality, dynamic range, and noise performance.
Panasonic Lumix DC-G100
- Sensor: 20MP Four Thirds CMOS sensor (17.3 x 13 mm)
- Pixel Resolution: 5184 x 3888
- ISO Range: 200 – 25600 native (100-25600 extended)
- RAW Support: Yes
- Anti-aliasing Filter: Yes
Panasonic Lumix DMC-ZS30
- Sensor: 18MP 1/2.3" CMOS sensor (6.17 x 4.55 mm)
- Pixel Resolution: 4896 x 3672
- ISO Range: 100 – 6400 native
- RAW Support: No
- Anti-aliasing Filter: Yes
What this means: The G100’s significantly larger sensor collects more light per pixel, resulting in cleaner, sharper images with better dynamic range and more depth, especially in low light. The ZS30, typical of compacts, struggles in dimmer environments and delivers images that are softer and grainier at higher ISOs.
In practice, I tested landscape shots side-by-side and found the G100 retained richer details in shadows without noisy artifacts, whereas the ZS30 images needed careful exposure and post-processing to compensate.
Autofocus Systems: Speed and Accuracy in Real Life
Autofocus is a decisive factor, particularly for wildlife, sports, or street photographers who need quick, reliable focus acquisition.
Panasonic Lumix DC-G100
- AF Type: Contrast detection, 49 focus points
- Face Detection: Yes
- Eye Detection: Yes (human subjects)
- AF Modes: Single, Continuous, Tracking, Selective
- Touch AF: Yes
Panasonic Lumix DMC-ZS30
- AF Type: Contrast detection, 23 focus points
- Face Detection: No
- Eye Detection: No
- AF Modes: Continuous (limited), Center, Multi-area
- Touch AF: Yes
Thanks to its newer tech and more focus points, the G100 provides more precise and dependable AF performance. The eye and face detection help in portraiture and event photography, locking focus exactly where you want it. The ZS30’s AF is adequate for casual snapshots but can struggle with fast-moving subjects and lacks intelligent tracking features.
Through repetitive autofocus speed tests (both on static and moving subjects), I found the G100’s tracking to be noticeably better, especially under tricky light.
Build Quality, Ergonomics, and Handling
How a camera feels in-hand directly impacts your shooting experience.
Panasonic Lumix DC-G100
- Body Type: SLR-style mirrorless (116x83x54 mm, 352g)
- Controls: Extensive physical dials, fully articulating 3" touchscreen (1840k dots)
- Viewfinder: Built-in electronic (0.73x magnification, 3680-dot resolution)
- Weather Sealing: None
- Battery Life: ~270 shots
Panasonic Lumix DMC-ZS30
- Body Type: Compact (105x59x28 mm, 198g)
- Controls: Limited physical controls, fixed 3" touchscreen (920k dots)
- Viewfinder: None (reliance on LCD)
- Weather Sealing: None
- Battery Life: ~260 shots
The G100 feels far more robust and “camera-like” with a good grip and tactile buttons that professionals expect. Its electronic viewfinder dramatically helps in bright conditions - a critical aid for shooting outdoors.
In contrast, the ZS30 is ultra-portable and pocketable - which is excellent for travel and street photography but sacrifices manual control and viewfinder functionality.
Touchscreens on both function well, but the G100’s articulated screen opens wide angles, including front-facing for vloggers or selfies.
Lens Ecosystem and Versatility
The interchangeable lens nature of the G100 vastly expands its creative potential:
-
Panasonic G100 uses the Micro Four Thirds mount with over 100 lenses available - from wide-angle primes to telephoto zooms, including excellent macro and fast portrait lenses.
-
Panasonic ZS30 has a fixed (non-interchangeable) 24-480mm (equiv.) f/3.3-6.4 zoom lens.
I tested the G100 with a sharp 25mm f/1.7 lens - producing gorgeous portraits with creamy bokeh impossible on the ZS30. The ZS30 shines if you want the zoom reach in a compact package but cannot match the optical quality or creative control of the G100’s interchangeable system.
Burst Shooting and Video Capabilities
For sports, wildlife, or storytelling, burst shooting and video specs are increasingly important.
Feature | Panasonic G100 | Panasonic ZS30 |
---|---|---|
Burst Rate | 10 fps | 10 fps |
Max Shutter Speed | 1/16000s (electronic shutter) | 1/1200s (mechanical shutter) |
Video Recording | 4K 30p, Full HD 120p slow-motion | 1080p 60p max |
Video Formats | MOV, H.264 | MPEG-4, AVCHD |
Microphone Input | Yes | No |
In-Body Stabilization | No (lens stabilization only) | Optical Lens Stabilization |
The G100’s ability to shoot 4K video combined with a microphone input and articulation screen makes it a solid choice for vloggers and hybrid shooters. The ZS30 is limited to Full HD and smaller codecs, more fitting for casual family video recording.
I tested video autofocus; the G100 smoothly tracked faces and maintained sharp focus. The ZS30 shows some focus hunting in video and lacks the professional audio options essential for content creators.
Specialized Photography Use Cases
Portrait Photography
- G100: Excellent skin tone rendering, quality lenses offering smooth bokeh, and eye/face detection autofocus make it highly suitable for portraits.
