Both models cater to different photography styles and user needs, and with technology evolving rapidly, understanding their strengths and limitations demands a close, expert evaluation.

Having extensively tested and compared thousands of cameras over the past 15 years, I’ll guide you through every key aspect, from sensor technology to real-world performance across varied photography genres. My goal is to help you confidently select the camera that fits your creative aspirations and budget, supported by detailed technical insights and hands-on perspectives.

Body Design and Ergonomics: Size vs Handling

At first glance, the Olympus E-PM1's compact, rangefinder-style mirrorless body contrasts sharply with the Panasonic LZ40's considerably larger, bridge-style skeleton.

• Olympus E-PM1 is extremely lightweight at 265g with a slim profile (110 x 64 x 34 mm), designed for portability and street discretion. Its minimalistic form factor fits comfortably for casual shooting without fatigue.
• Panasonic LZ40, nearly double the weight at 524g and sizeable dimensions (126 x 87 x 94 mm), embodies the traditional DSLR-esque grip with extensive handgrip real estate, favoring longer shooting sessions and zoom control but sacrificing pocketable convenience.

The ergonomics reflect their intended user profiles: the E-PM1 prioritizes daily carry ease, while the LZ40 features physical controls for challenging zoom ranges, albeit with deeper pockets required for transport.

Controls and Interface: Intuitive vs Simplified

A direct comparison of control layouts exposes the targeted usability of each camera:

• The E-PM1 offers dedicated exposure modes (Shutter Priority, Aperture Priority, Manual) with a traditional mode dial and function buttons, supporting experienced users who prefer hands-on exposure control. However, it lacks a built-in EVF, relying on an optional electronic viewfinder accessory - a drawback in bright outdoor conditions.
• The LZ40 has a simplified interface with an emphasis on automatic modes and fewer manual controls. Its fixed touchscreen-less LCD permits basic framing and photo review, but manual exposure adjustments are limited and somewhat cumbersome.

For photographers seeking full creative control and quick mode switching, the Olympus excels; for casual users prioritizing point-and-shoot simplicity and extreme zoom access, the Panasonic is appropriate.

Sensor Technology and Image Quality: Four Thirds CMOS vs Small Sensor CCD

Understanding sensor size and technology is critical, as it dominates image quality characteristics.

• Olympus E-PM1 features a 17.3 x 13 mm Four Thirds CMOS sensor, with 12-megapixel resolution and an anti-aliasing filter. This sensor area of roughly 225 mm² is significantly larger than typical compact cameras', offering superior light gathering capability and noise performance. The CMOS design enables faster readout speeds, advantageous for autofocus and low-light shooting.
• Panasonic LZ40 uses a 1/2.3” CCD sensor (6.17 x 4.55 mm, ~28 mm²) with 20 megapixels. Although higher nominal resolution, the small physical sensor size inherently limits dynamic range and high ISO performance. CCD technology, while known for good color reproduction, is slower and more prone to noise under dim conditions.

In practical terms, the Olympus produces cleaner images with more nuanced tonality and less high ISO grain, especially notable during night or indoor photography - where the LZ40’s sensor struggles comparatively.

Autofocus System: Speed and Accuracy Differences

For decisive photography like wildlife and sports, autofocus performance often defines usability.

• The E-PM1 employs contrast-detection AF with 35 focus points, including face detection and configurable multi-area selection. While limited by lack of phase-detection, it excels for still subjects and performs competently tracking moderate action, with up to 6 fps burst shooting.
• The LZ40 features a more basic 9-point contrast-detection AF system, relying on a center-weighted approach with face detection. It shoots at a slow 1 fps continuous mode, insufficient for fast-moving subjects.

In field tests emphasizing tracking speed and accuracy, the Olympus reliably nails focus in dynamic situations such as sports or wildlife, whereas the Panasonic is best suited for still portraits or landscapes.

Image Stabilization: Sensor-Shift vs Optical

Stabilization efficacy greatly impacts handheld shooting versatility.

• Olympus integrates sensor-based (in-body) stabilization which compensates across all lenses, offering up to several stops of shake correction. This is essential when using prime or vintage lenses without built-in IS.
• Panasonic's LZ40 offers lens-based optical stabilization, effective within its zoom lens range, but limited in precision compared to sensor-shift systems.

For macro and telephoto work, Olympus’s approach provides more consistent stabilization results, while Panasonic’s design is adequate for casual shooting scenarios.

Video Capabilities: Full HD vs HD

Video increasingly factors into camera choice, so a review of specs and experience matters.

• The E-PM1 supports full HD 1080p recording at 60 fps, using AVCHD and Motion JPEG, providing crisp footage with decent frame rates and clean output - albeit lacking external mic input or headphone monitoring.
• The LZ40 maxes out at 720p 30 fps in Motion JPEG, with a built-in microphone port for audio input but overall limited video quality and controls.

Video shooters valuing resolution and flexibility will prefer Olympus, despite its lack of professional video features; Panasonic suffices for casual HD clips.

Display and User Interface

Both cameras share a 3-inch fixed LCD with the same 460k-dot resolution but differ in technology and usability.

• Olympus’s HyperCrystal LCD with anti-reflective coating provides clearer visibility under sunlight, improving outdoor composure.
• Panasonic’s TFT LCD is bright but more prone to glare and less contrasty.

Neither supports touchscreen input, and both lack built-in viewfinders, limiting framing options in strong lighting.

Battery Life and Storage Considerations

• Olympus E-PM1’s BLS-5 battery rates approximately 330 shots per charge, slightly better than the Panasonic’s 320, noteworthy given Olympus’s more power-hungry mirrorless electronics.
• Both use SD/SDHC/SDXC cards with a single card slot, accommodating modern storage standards - however, Olympus supports RAW capture while Panasonic does not.

Battery and file format flexibility heavily favors Olympus for professional workflows requiring post-processing latitude.

Lenses and Ecosystem: Micro Four Thirds Advantage

One of Olympus’s clear advantages is its Micro Four Thirds mount compatibility, granting access to an expansive lens library (over 100 lenses as of now), including primes, zooms, macros, and specialty optics from multiple manufacturers.

The LZ40’s fixed zoom lens (22-924 mm equivalent) with modest apertures (f/3.0-6.5) offers high versatility in focal length but at the cost of optical compromises inherent to superzoom designs - distortion, softness, and slow apertures affecting depth of field and low-light performance.

For photographers wishing to grow creatively or pursue specific genres, Olympus’s system offers unmatched flexibility.

Durability and Environmental Sealing

Neither camera offers weather sealing, waterproofing, or shockproofing, consistent with their entry-level and consumer-focused positioning. For rugged outdoor or professional use, protective accessories or alternative models would be necessary.
