Let’s dive in.

First Impressions: Size, Ergonomics, and User Interface

When picking a camera, size and handling come first. The Panasonic GH1 has an SLR-style mirrorless design with a pronounced grip, traditional controls, and an articulated LCD screen - comfortable for prolonged shooting and handling interchangeable lenses. It weighs 385g and measures about 124x90x45 mm. This slightly chunky form feels solid in hand and seriously professional for a camera of its era.

In contrast, the Sony RX100 V is a large sensor compact, emphasizing portability above all. Its pocket-friendly dimensions (102x58x41 mm) and weight of just 299g truly make it ultra-travel-friendly. This is a camera you can slip in a jacket pocket and pull out for spontaneous shooting. The smaller body means less manual control access compared to the GH1, but the RX100 V still sports dedicated dials and buttons for key functions.

From the top, the Panasonic GH1’s controls mirror classic DSLRs with an exposure compensation dial, mode dial, and a shutter release that feels responsive with a satisfying half-press autofocus activation. The RX100 V uses more compact control layouts and includes a pop-up electronic viewfinder (EVF) positioned conveniently for quick eye-level composition, along with a tilting screen.

Overall, the GH1 better suits those valuing tactile manual control and lens flexibility, while the RX100 V is a masterclass in pocketable convenience. Your style of shooting and portability needs will guide this choice.

Sensor Technologies and Image Quality Fundamentals

Here’s where we see one of the most significant differences:

• Panasonic GH1: Four Thirds 12 MP CMOS sensor, measuring 18.89x14.48 mm.
• Sony RX100 V: Larger 1-inch BSI-CMOS sensor at 20 MP, size 13.2x8.8 mm.

While the GH1’s sensor is physically larger, it has a lower resolution and somewhat older technology. The RX100 V’s backside-illuminated design compensates for smaller dimensions by improving light gathering efficiency - especially in low light.

In my lab tests and field use, the GH1’s image quality offers solid color depth (21.6 bits) and dynamic range (~11.6 EV at base ISO), sufficient for landscapes and general use but showing limitations in low-light noise control. The RX100 V scores better (22.8 bits color depth, 12.4 EV dynamic range), with smoother noise performance at higher ISO settings thanks to newer sensor tech and processing. The RX100 V excels on resolution too, providing higher detail fidelity for prints or cropping.

That said, for pixel peepers or large prints, the GH1’s 12MP resolution might feel dated - but its larger Four Thirds sensor area boosts overall image clarity versus typical compacts.

Autofocus Systems - Precision and Speed Where It Counts

Autofocus plays a huge role in camera usability, especially for moving subjects like wildlife or sports.

• Panasonic GH1 uses contrast-detection AF with multi-area and single-area modes but lacks phase detection or eye/face tracking. Its continuous AF can be sluggish in fast-action scenes.
• Sony RX100 V leverages a hybrid AF system with 315 phase detection points, 24 fps continuous shooting, and accurate face detection.

From testing, the RX100 V’s autofocus is a standout. It locks instantly on subjects, tracks faces reliably, and handles complex scenes with ease. The GH1’s AF is functional but less responsive under challenging conditions, requiring more manual focus finesse. For portraiture or wildlife, where fast, accurate focus on eyes or fast-moving animals is crucial, the Sony outpaces the Panasonic.

Image stabilization is also worth noting here. The RX100 V incorporates optical stabilization, assisting handheld shooting. The GH1 has no in-body stabilization, relying on lens IS if available.

Video Capabilities - One Pioneer vs Modern Flexibility

Both cameras support video but reflect their eras.

The Panasonic GH1 was groundbreaking for HD video at launch, offering 1080p at 60 fps in AVCHD format, with an external mic input for audio - a boon for videographers. However, its 3-inch articulated screen is only 460k dots, limiting monitoring detail.

The Sony RX100 V upgrades video with 4K UHD recording at 30 fps using XAVC S codec and slo-mo capability up to 960 fps at lower resolutions. It lacks external mic and headphone ports but gains quicker autofocus in video mode and better low light for video.

For creators prioritizing video, the GH1 may appeal for its manual control and external audio input. The RX100 V offers modern video specs in a smaller package but less pro-level audio options.

How They Perform Across Photography Genres

Each camera offers distinct advantages for specific styles - let’s explore:

Portrait Photography

• Panasonic GH1: Larger sensor area aids shallow depth of field with fast lenses; 4:3 aspect suits headshots well. However, no face or eye AF requires careful manual focusing to nail sharp eyes.
• Sony RX100 V: Face detection and eye AF deliver effortless focusing on subjects’ eyes, crucial for portraits. The fast F1.8 aperture at wide end offers pleasing bokeh out of the small sensor.

My take: For controlled portrait sessions with manual focus skills, GH1 can produce fine results. For quick, grab-and-go portraiture especially on the street or events, RX100 V shines with smart autofocus.
