Olympus E-M10 II carries the heft and grip of a traditional mirrorless camera, making it comfortable for extended handheld shoots, especially with longer lenses. Its SLR-style build includes a pop-up EVF that’s crisp and highly detailed, crucial for precision framing. The tilting touchscreen adds flexibility for creative angles.
In contrast, the Panasonic ZS20 is ultra-compact, designed for travel ease. Its small footprint and light weight favor portability but come with compromises in ergonomics and control. No viewfinder means you rely solely on the rear LCD, which is less detailed and fixed in place.
If you prioritize a tactile, engaging shooting experience with manual control, the Olympus wins here. For casual users wanting pocketable convenience and immense zoom reach, the ZS20 excels.
Sensor Technology & Image Quality: The Heart of the Camera
Image quality hinges on sensor size, resolution, and processing power. Let's break down the essentials.
Spec | Olympus E-M10 II | Panasonic ZS20 |
---|---|---|
Sensor Type | Four Thirds CMOS | 1/2.3" CMOS |
Sensor Size (mm) | 17.3 x 13 (224.9 mm²) | 6.08 x 4.56 (27.7 mm²) |
Resolution (MP) | 16 | 14 |
Native ISO Range | 200 - 25600 | 100 - 6400 |
Image Processor | TruePic VII | Not specified |
Raw Support | Yes | No |
Anti-aliasing Filter | Yes | Yes |
The Olympus’s Four Thirds sensor is substantially larger than the Panasonic’s tiny 1/2.3" chip - almost eight times the surface area. This size difference generally translates to far better image quality, especially in low light. The E-M10 II’s sensor captures more detail and richer tones, aided by the TruePic VII processor that handles noise reduction and color fidelity intelligently.
Raw support on the Olympus unlocks maximum flexibility in post-processing, an essential feature for enthusiasts and professionals. The Panasonic ZS20, lacking raw, is constrained to JPEGs, which might limit advanced edits.
Although the ZS20’s 14MP resolution is respectable for a small sensor, the image quality falls short in dynamic range, color depth, and noise performance, particularly beyond ISO 400-800. Olympus’s 16MP sensor delivers sharper images with better skin tone reproduction, essential for portraits and professional work.
Autofocus and Speed: Staying Sharp When It Counts
Autofocus (AF) systems are critical for capturing fleeting moments. Here’s how these two cameras compare:
Feature | Olympus E-M10 II | Panasonic ZS20 |
---|---|---|
AF System | Contrast-detection, 81 points | Contrast-detection, 23 points |
Face Detection | Yes | No |
Continuous AF | Yes | Yes |
AF Modes | Single, Continuous, Tracking | Tracking, Center |
Eye AF | No | No |
Burst Shooting (fps) | 8.0 | 10.0 |
The Olympus uses a fine-grained 81-point contrast AF system complemented by face detection, which noticeably helps in portrait shooting and focusing on moving subjects with confidence. Although lacking phase detection, its AF tracking is responsive in good light.
The Panasonic employs a more basic 23-point system without face detection, which can impact accuracy in complex scenes or portraits. Its higher 10 fps burst speed is an advantage for casual action but may suffer from slower focus acquisition between frames.
In practical use, the Olympus’s autofocus system is more precise and flexible, especially under varied lighting. The face detection aids portrait and street photography, while its manual focus ring and focus peaking improve creative control.
Handling and User Interface: Controls Matter
Your interaction with the camera ultimately affects your shooting enjoyment and efficiency.
The Olympus E-M10 II boasts dedicated dials for shutter speed and exposure compensation, customizable buttons, and a well-laid-out menu system that's intuitive. This design invites experimentation and fast access to manual modes - a big boon for learners and pros alike.
By contrast, the Panasonic ZS20's compact body limits physical controls. It relies heavily on touchscreen menus and fewer buttons, which may slow operation, particularly when changing settings on the fly.
The Olympus’s electronic viewfinder (EVF) offers eye-level shooting, critical in bright light or for precise composition. The tilting touchscreen enables work from creative angles. The Panasonic offers a fixed LCD, which can be restrictive.
For photographers who value quick, tactile control in dynamic environments such as sports or street photography, the E-M10 II’s ergonomics stand out.
Optical Systems: Lenses and Zoom Performance
The Olympus E-M10 II uses the Micro Four Thirds lens mount, while the Panasonic ZS20 has a fixed superzoom lens.
Camera | Lens Mount / Type | Focal Length | Max Aperture | Zoom Range Multiplier |
---|---|---|---|---|
Olympus E-M10 II | Micro Four Thirds (Interchangeable) | N/A (varies by lens) | Depends on lens | 2.0x crop factor |
Panasonic ZS20 | Fixed Zoom Lens | 24-480 mm (equiv.) | f/3.3 - f/6.4 | 20x optical zoom |
The Olympus benefits from access to an extensive Micro Four Thirds lens ecosystem - over 100 lenses covering wide angle, primes, macro, telephoto, and professional optics. This flexibility allows you to tailor the system precisely to your photography needs and styles.
The Panasonic comes with a generous built-in 20x zoom (24-480mm 35mm equivalent), perfect for travel and wildlife shooters on a budget who want reach without carrying multiple lenses. However, the slower maximum aperture at the telephoto end limits low-light and shallow depth-of-field potential.
If you want versatility and image quality optimized for portraits, landscapes, or professional applications, Olympus’s interchangeable lens system outperforms the fixed lens solution.
Display and Viewfinder: Composing Your Shot
-
Olympus E-M10 II sports a high-resolution tilting LCD touchscreen (1,040k dots) plus an EVF with 2,360k dots resolution, offering dual flexibility. The EVF excels for bright conditions, reducing glare and aiding precise framing.
-
Panasonic ZS20 relies solely on a fixed, lower resolution 460k dot LCD, which is harder to view in sunlight and limits creative shooting angles.
For serious photographers and videographers, having both a quality EVF and versatile LCD tilt is invaluable for composition and usability.
