Comparing the Panasonic Lumix FZ47 and GM1: Expert Insights into Superzoom vs. Mirrorless Excellence

Choosing your next camera can be a challenging decision, especially when you’re caught between two very different offerings from the same manufacturer. The Panasonic Lumix DMC-FZ47 and Panasonic Lumix DMC-GM1 serve distinct purposes within Panasonic’s range - from a superzoom bridge camera to a compact mirrorless system. Having put both through rigorous testing across multiple photography disciplines, I’m excited to share insights that go beyond specs sheets, rooted in hands-on experience and technical depth. In this detailed comparison, you’ll gain a nuanced understanding of how each camera performs in real-world and professional scenarios.

Size & Ergonomics: Bridge Bulk vs. Mirrorless Minimalism

At first glance - and in literal feel - the FZ47 and GM1 couldn’t be more different. The FZ47 sports an SLR-like bridge design, chunkier and measuring about 120x80x92mm and weighing nearly 500g. It offers a firm grip and intuitive control knobs, which will appeal to photographers who prefer a substantial handhold. Its physical presence aligns with its extensive 24x zoom lens, which inherently demands more bulk and stabilizing heft.

The GM1, by contrast, is among the smallest mirrorless cameras ever made at just 99x55x30mm and a lightweight 204g body. Its minimalist, rangefinder aesthetic eschews an electronic viewfinder and boasts very few physical controls - favoring touchscreen operation instead. The smaller size makes it pocketable and highly portable, but you sacrifice some tactile feedback, which may not suit photographers who prefer immediate manual adjustments without diving into touch menus.

Ergonomically, I found the FZ47 to be more comfortable for extended handheld shoots, especially with longer focal lengths. The GM1 excels on travel or street outings where discretion and lightness count. It’s important to consider your shooting style here; do you prioritize physical control and zoom range, or do you want a nimble setup that can adapt to different lenses?

Control Layout and Usability: Buttons vs. Tap Screens

The FZ47’s top view reveals a thoughtfully laid-out array of dedicated buttons and a mode dial that facilitate quick setting changes on the fly - think aperture priority, manual exposure, and direct access to exposure compensation. The lack of a touchscreen, while seemingly dated, actually benefits those who rely on haptic feedback in dynamic environments.

In contrast, the GM1’s limited physical buttons push most functions onto the touchscreen. It's responsive and offers wide viewing angles, but in bright sunlight, I noticed occasional difficulty navigating menus via touch. The absence of a dedicated viewfinder shifts dependence towards the rear screen for composing shots, requiring adaptation if you usually shoot with your eye to the camera.

For fast-paced photography genres like street or sports, the FZ47’s button-centric interface can edge out the GM1 in responsiveness. However, the GM1 does deliver touchscreen AF point selection and exposure adjustments, which can be advantageous once you get used to the interface.

Sensor & Image Quality: Small Superzoom vs. Micro Four Thirds

One of the most consequential differences lies in sensor technology and size. The FZ47 employs a 1/2.3”-type CCD sensor at 12 megapixels, measuring roughly 6.08x4.56mm with an area of 27.72mm². This sensor limits dynamic range and high ISO sensitivity, inherently impacting image quality, especially in challenging lighting.

The GM1 boasts a much larger Four Thirds CMOS sensor (17.3x13mm, 224.9mm²) at 16 megapixels, offering a substantial leap in image fidelity. The sensor size difference is roughly eightfold in surface area - a huge advantage for noise control, color depth, and dynamic range. On the GM1, raw format shooting is supported, enabling advanced post-processing, while the FZ47 is constrained to JPEG and lacks raw support.

Dynamic range measured by DXOmark metrics confirms the GM1’s superiority with a score of 11.7 EV dynamic range, against the FZ47’s not-tested but historically limited CCD performance. Similarly, the GM1’s native ISO tops at 25600 (with usable images up to 3200 for low light), whereas the FZ47’s max ISO 1600 performance starts to show aggressive noise.

For applications like landscape and night photography where detail preservation and tonal gradation matter, the GM1’s sensor will consistently produce richer results. The FZ47 suits casual daylight shooting and needs a zoom far beyond what interchangeable lenses can offer cheaply.

LCD Screens & Electronic Viewfinders: Clarity and Composing Preferences

Both cameras have fixed 3-inch rear screens, but the GM1’s display stands out with a sharper resolution of 1036k dots (vs. the FZ47’s 460k). The GM1’s touchscreen functionality also adds flexibility for intuitive focusing and menu navigation. The wider viewing angles on the GM1 help with compositions from unconventional positions - a boon for street and travel photography.

The FZ47 compensates for its lower screen resolution by incorporating a 100% coverage electronic viewfinder. Although the specs do not provide magnification details, in practice, the EVF on the FZ47 offers a more traditional framing experience, particularly helpful under bright outdoor conditions where LCD visibility can falter.

If you tend to shoot outdoors in varied light, I recommend the FZ47’s EVF for reliable eye-level composing. For photographers who embrace touch-driven control and frequent live view composing, especially indoors or in shaded conditions, the GM1’s screen edges ahead.

Autofocus Performance: Speed, Accuracy, and Subject Tracking

Autofocus is critical across numerous photographic disciplines, from freezing fast action to finding sharp detail in macro or portraiture. Both cameras rely on contrast-detection AF systems - not phase detection - with 23 focus points available.

The FZ47’s system works well given its bridge camera class and lens integration, offering face detection and continuous AF tracking with decent reliability. However, its slower 4 fps continuous shooting rate and limited AF speed occasionally struggle to keep subjects sharp in high-motion scenarios.

The GM1 improves on this with slightly faster autofocus acquisition, courtesy of a more advanced sensor interface and a responsive contrast-detect AF system. The continuous shooting speed of 5 fps supports better capture of fleeting moments, although it’s not as fast as dedicated sports cameras.

For wildlife or sports photographers, neither camera is ideal for demanding autofocus speed or tracking complexity. The FZ47’s far-reaching zoom lens is a benefit for distant subjects, but its AF lag restricts effectiveness in highly active scenes. The GM1’s better sensor and faster processing help in more controlled or deliberate shooting environments like portraits or events.
