The G85 boasts environmental sealing that resists dust and moisture, extending functionality in challenging weather - a significant asset for outdoor, travel, and wildlife photographers. The LZ40 lacks weather resistance, rendering it less dependable in adverse conditions.

Summary: The G85’s SLR-style, weather-sealed body with complete manual control suits advanced photographers valuing ergonomic sophistication. The LZ40 is a budget-conscious solution for straightforward shooting without modularity or ruggedness.

Sensor Technology and Image Quality

At a fundamental level, sensor design dictates resolution, dynamic range, noise performance, and color fidelity - cornerstones of image quality.

Sensor Size and Resolution

• G85: Utilizes a 17.3 x 13 mm Four Thirds CMOS sensor with 16 megapixels. The absence of an optical low-pass filter enhances sharpness. The 2.1x crop factor influences lens equivalency.

• LZ40: Sports a tiny 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm and packing around 20 megapixels. Despite higher pixel count, the sensor’s reduced physical dimensions hamper light gathering capability and dynamic range.

Dynamic Range and Color Depth

DXOMark scores (where available) reveal the G85’s sensor shows a healthy dynamic range of 12.5 EV and color depth of 22.8 bits, surpassing typical MFT standards and enabling nuanced gradations critical in landscape and portraiture.

The LZ40 has not been officially tested by DXOMark, but the CCD sensor type combined with tiny pixel pitch suggests notable limitations in highlight retention and shadow detail, with compromise in color fidelity particularly at higher ISOs.

Low-Light and High ISO Performance

The G85’s ISO sensitivity extends natively to 25600 with usable results up to ISO 3200-6400 in practice, aided by modern noise reduction algorithms. Its sensor-based 5-axis image stabilization further compensates for camera shake during slow shutter speeds.

LZ40’s maximum ISO is 1600 (boosted to 6400, although with substantial noise), and despite optical stabilization, its small sensor architecture yields significantly inferior low-light imaging and color noise artifacts.

Autofocus and Performance Capabilities

Fast and accurate autofocus (AF) is pivotal, especially in sports, wildlife, and street photography.

Autofocus System

• G85: Features 49 contrast-detection AF points with face detection, tracking, and eye detection capabilities. While lacking phase-detection AF, its hybrid AF system remains responsive due to the sophisticated sensor and processor integration.

• LZ40: Employs 9 AF points, all contrast-detection, with face detection but no advanced subject tracking or eye AF. Focus speed and accuracy are sufficient for static scenes but lag in dynamic scenarios.

Burst Shooting and Shutter Speeds

• G85: Offers 9 frames per second (fps) continuous shooting, adequate for mid-level sports and wildlife action capture.

• LZ40: Limits to 1 fps burst rate, unsuitable for any fast-paced photography.

Maximum shutter speeds diverge sharply: the G85’s mechanical shutter maxes out at 1/4000s and an electronic shutter up to 1/16000s, enabling capture of fast action and use of wide apertures in daylight. The LZ40’s limit of 1/1500s restricts such shooting versatility.

Image Stabilization

The G85’s 5-axis in-body image stabilization (IBIS) synergizes with lens stabilization, greatly enhancing handheld shooting usability across genres, especially in low light or telephoto situations.

The LZ40 relies solely on optical stabilization integrated into its lens assembly, effective for modest shake reduction but no match for the G85’s sensor-based system.

Lens Ecosystem and Compatibility

Interchangeable lens systems afford creative freedom and specialized optical tools.

• G85: Employs the Micro Four Thirds mount with access to over 100 lenses from Panasonic, Olympus, and third parties, spanning primes, zooms, macros, and specialty lenses. This extensive ecosystem is a major advantage for photographers seeking versatility and future upgrades.

• LZ40: Fixed lens design with a substantial 22-924 mm (42x zoom) focal range and aperture from f/3.0 to f/6.5. This all-in-one approach simplifies usage but caps optical quality and creative possibilities to the limitations of the built-in zoom.

Specialized Photography Use Cases

We now explore practical suitability of both cameras across major photographic disciplines based on their technical profiles and real-world performance.

Portrait Photography: Skin Tone Accuracy, Bokeh, and Eye Detection

• G85: The 16MP MFT sensor yields natural skin tones when using appropriate lenses. Its lack of an antialias filter sharpens details which benefits portrait clarity. Eye AF and face-detection autofocus support precise focus in shallow depth-of-field contexts, achievable with fast primes (e.g., 42.5mm f/1.7).

• LZ40: The small sensor, limited aperture, and fixed lens restrict shallow depth of field and expressive bokeh. Face detection is present but less reliable under complex lighting or multiple subjects.

Assessment: The G85 is clearly superior for portrait work, providing both technical image advantages and AF tools to isolate subjects effectively.
