In-Depth Sensor and Image Quality Analysis

Sensor Size and Technology

The Olympus E-PM2 employs a Four Thirds type MOS sensor measuring 17.3 x 13 mm, while the Panasonic FZ28 uses a significantly smaller 1/2.3-inch CCD sensor of 6.08 x 4.56 mm. This physical sensor dimension disparity of roughly 8x in surface area directly impacts image quality aspects including noise performance, dynamic range, and resolution capability.

The larger sensor of the E-PM2 captures substantially more light, facilitating higher signal-to-noise ratio and better color fidelity. This is demonstrated in its DxOMark scores: an overall score of 72, color depth of 22.7 bits, and dynamic range of 12.2 EV. In contrast, the FZ28’s score of 27 overall, with color depth 17.9 bits and dynamic range 10.1 EV, reflects inherent limitations from the smaller sensor size and CCD technology.

Resolution and Image Output

• E-PM2: 16MP (4608 x 3456 pixels), which delivers sufficient detail for large prints and cropping latitude.
• FZ28: 10MP (3648 x 2736 pixels), adequate for general use but with lower resolving power.

The difference in image resolution combined with sensor size means the Olympus provides cleaner, sharper files with better gradation in shadows and highlights - particularly valuable in critical photo editing workflows.

Autofocus Systems and Real-World Performance

Autofocus Technology

• Olympus E-PM2 utilizes contrast-detection AF with 35 focus points and face detection, including continuous and tracking modes. Although it lacks phase-detection AF, the Smart Contrast AF algorithm works efficiently in well-lit environments.

• Panasonic FZ28 is limited to contrast-detect AF with fewer focus points and no continuous or tracking autofocus capabilities. Lack of face or eye detection is a notable drawback.

Speed and Accuracy Testing

In practical testing scenarios:

• The E-PM2 reliably acquires focus within 0.3-0.5 seconds under ample light conditions, with continuous autofocus maintaining subject lock during moderate movement - crucial for portrait and street photography.
• The FZ28’s autofocus is noticeably slower (~0.8-1.5 seconds), often hunting in low contrast environments, struggling with moving subjects due to absence of continuous AF tracking.

Impact on genres:

• Wildlife and Sports: The E-PM2’s more responsive AF system and burst mode at 8 fps provide significant advantages in capturing decisive moments compared to the FZ28’s 3 fps and slow AF.

• Macro and Portrait: The E-PM2’s ability to reliably lock focus on subjects’ eyes with face detection improves shooting efficiency and image sharpness.

Ergonomics, Controls, and User Interface

Handling and Body Design

Despite the E-PM2’s “rangefinder-style” mirrorless configuration, it remains highly compact at 110 x 64 x 34 mm and weighs 269g (excluding lens), promoting portability for travel and street photography. The FZ28, with dimensions 118 x 75 x 89 mm and weight 417g, is more cumbersome and lacks the same level of handling refinement.

Screen and Viewfinder

• The E-PM2 features a fixed 3-inch touchscreen with 460k dot resolution, enabling intuitive menu navigation and touch AF. The absence of a built-in viewfinder can be somewhat limiting but an optional EVF is available.

Lens Ecosystem and Optical Versatility

Interchangeable vs Fixed Lens Design

• The E-PM2 benefits from the Micro Four Thirds lens mount with access to over 100 lenses across wide-angle, telephoto, macro, and prime categories, including high-quality options from Olympus, Panasonic, and third-party manufacturers. This versatility supports extensive photography disciplines.

• The FZ28 relies on a fixed 27-486 mm (18x zoom) F2.8–4.4 lens. While impressive for reach and macro (down to 1cm focus), it offers no possibility for lens swap, limiting adaptability and optical quality at extremes of zoom range.

Image Stabilization

• Olympus implements sensor-shift image stabilization (sensor-based), effective with any attached lens, aiding handholding at slower shutter speeds and video capture.

• Panasonic employs optical image stabilization within the lens assembly, which works reasonably well but cannot be upgraded or replaced.

Practical Implications

• For landscape and portrait photographers, the E-PM2’s ability to use prime lenses with wide apertures excels in producing shallow depth of field and superior image quality.

• The FZ28’s superzoom caters to casual wildlife or travel users requiring extended reach without lens changes, but compromises sharpness and light gathering compared to dedicated telephotos.

Burst Rate, Video, and Low-Light Capabilities

Continuous Shooting and Buffer

• E-PM2: 8 fps continuous shooting with good buffer capacity supports action photography.
• FZ28: 3 fps burst rate only - limiting in fast-paced environments.

Video Recording

• The Olympus records Full HD 1080p at 30 fps (MPEG-4, H.264, Motion JPEG). However, its lack of microphone/headphone ports restricts audio quality and monitoring capabilities.

• The FZ28 records up to 720p HD at 30 fps, a resolution inadequate by modern standards and lacks HDMI output.

Low Light and High ISO

The E-PM2’s sensor achieves a maximum native ISO of 25600, with effective performance up to ~ISO 3200 before noise becomes intrusive. The FZ28 tops at ISO 6400 but practically usable ISO levels hover around 400 due to noise.
