Comparing the Olympus E-420 and Olympus PEN E-PL1s: A Hands-On Deep Dive for Aspiring Photographers

When it comes to entry-level cameras in the Olympus lineup, two models stand out from the late 2000s and early 2010s era: the Olympus E-420, a compact DSLR introduced in 2008, and its mirrorless sibling, the Olympus PEN E-PL1s, launched a couple of years later in 2010. Both target photography enthusiasts stepping up from point-and-shoots but doing so via different technological paths. After spending extensive hours shooting with both, testing every major photography facet from portraits to landscapes, and stacking their specifications side-by-side, I’m here to help you decide which of these venerable options suits your style - or if you’re simply curious how much progress Olympus made in those couple of years.

Before we jump in, here’s a quick glance at how these two cameras compare physically:

The E-420 is noticeably chunkier and heftier, a quintessential DSLR feel. Meanwhile, the E-PL1s embraces the mirrorless philosophy, being smaller, lighter, and more travel-friendly. You’ll want to keep these differences in mind, especially if portability matters.

A Tale of Two Bodies: DSLR Muscle vs. Mirrorless Compactness

Starting with the basics, the E-420 sticks to the traditional DSLR blueprint - an optical pentamirror viewfinder covers about 95% of your frame and delivers a magnification of 0.46x. It’s robust and offers an unmistakable DSLR grip. For users new to this camera type in 2008, its form factor was a comfortable middle ground: not bulky yet reassuringly substantial.

The E-PL1s, however, captures the trend shift toward mirrorless models with a rangefinder-inspired body style. It omits a built-in viewfinder altogether but offers an optional electronic viewfinder if you want one (a separate purchase). The rear LCD is front and center for composition and review. The 2.7-inch screen with a 230K dot resolution is identical across both cameras but improved slightly on the E-PL1s with a much better HyperCrystal LCD with anti-reflective coating, reducing glare in daylight shoots.

Speaking of controls, the DSLR body’s dedicated dials and buttons (see the top view below) give you tactile, speedy access to shutter speed, aperture, and ISO. The mirrorless E-PL1s simplifies the control scheme, reflecting its beginner-friendly leanings.

From my testing, I find that the E-420’s DSLR ergonomics still appeal to photographers who crave manual control and feel - particularly for genres like sports or wildlife where fast tactile changes are crucial. The E-PL1s trades some of that for convenience without the mirror’s mechanical complexity.

Sensor Technology and Image Quality: Subtle but Meaningful Differences

Both cameras ride on the Micro Four Thirds sensor platform, measuring 17.3 x 13 mm, which is quite compact compared to APS-C or full-frame sensors. This sensor size offers a crop factor of 2.1x, meaning your lenses have a narrower field of view but gain extra reach - great for telephoto work, less so for ultra-wide landscapes.

Now, the E-420 offers a 10-megapixel CMOS sensor processed by the TruePic III engine, whereas the E-PL1s upgrades to a 12-megapixel sensor paired with the TruePic V processor. The jump in resolution and processing suggests better detail rendition and noise management on the newer mirrorless model.

Here’s a snapshot of sensor specs and DxO Mark scores where available:

Although Olympus’s early Micro Four Thirds sensors don’t match the dynamic range or low-light finesse of larger sensors, the E-PL1s provides a noticeable boost in the max native ISO - extending up to 6400 compared to 1600 on the E-420. That alone expands the potential for handheld low-light and night photography.

In my real-world tests - think interiors, twilight cityscapes, and dimly lit events - the E-PL1s held its ground by delivering cleaner output at ISO 1600 and beyond, while the E-420’s images started to show grain and loss of sharpness earlier. This makes the E-PL1s more versatile, especially for street photography and casual night shooting.

Autofocus and Continuous Shooting: Precision Versus Speed

Autofocus is where the DSLR roots of the E-420 both help and hinder it. Equipped with just 3 focus points, focusing was sometimes sluggish and less reliable in low-contrast situations. The AF system combined phase-detection and contrast-detection methods, but lacked face detection - a feature that was barely emerging at the time.

On the other hand, the E-PL1s leveraged Olympus’s improved contrast-detection AF with 11 focus points and face detection capabilities. It was arguably slower than present-day AF systems but noticeably better at locking focus quickly and accurately in a broader array of situations, including live view and video.

Here’s a side-by-side of continuous shooting capabilities:

• E-420: 4 frames per second (fps)
• E-PL1s: 3 fps

The DSLR E-420’s faster burst mode made it better suited for action photography like sports or wildlife – though its limited AF points meant tracking a fast-moving subject was a challenge. The E-PL1s, despite slightly slower shooting speed, compensated with more intelligent AF tracking.

For wildlife photography, I found the E-420 demanding patience and pre-focusing. The E-PL1s was more forgiving but neither model feels optimal for high-speed, professional action capture today.

Build Quality, Weather Resistance, and Handling in Use

Neither camera offers weather sealing or ruggedization, so both require careful handling in harsh environments. The E-420 is built around a compact SLR body with a magnesium alloy chassis for moderate durability. The E-PL1s, designed for casual use, employs a plastic body shell making it lighter but more vulnerable to rough treatment.

In terms of battery life, here’s what you can expect:

• E-420: Approximately 500 shots per charge
• E-PL1s: Around 290 shots per charge

That difference is typical for DSLRs versus mirrorless cameras of this generation. The E-420’s larger battery and less energy-intensive optical viewfinder help stretch its endurance. I experienced this firsthand on longer shoots where the E-420’s battery easily lasted a full day, while the E-PL1s required spare batteries for heavy use.

LCD and User Interface: Composing and Reviewing Shots

Though the screen size and resolution for both cameras are identical at 2.7 inches and 230K dots, the E-PL1s' LCD benefits from a HyperCrystal AR coating, drastically improving sunlight visibility.

Without a built-in viewfinder, the E-PL1s depends heavily on its LCD for framing, making the screen quality crucial in bright outdoor conditions. It delivered a more comfortable experience shooting outside.

The E-420's optical viewfinder offers the advantage of no lag, perfect clarity, and natural eye contact with the scene. For users accustomed to the DSLR style, this remains a compelling reason to choose it, especially in bright sunlight or fast action.

Lens Ecosystem and Mount Compatibility: The Heart of the System

Both cameras utilize the Micro Four Thirds lens mount, but here’s an interesting tidbit: the E-420 uses the Four Thirds lens mount, not Micro Four Thirds. This is a key difference many overlook.

• Olympus E-420: Four Thirds mount, compatible with 45 lenses that match this DSLR mount type. Mostly legacy DSLR lenses; bulky compared to mirrorless.

• Olympus E-PL1s: Micro Four Thirds mount, compatible with over 100 lenses (107+ including third-party options). Smaller, lighter lenses designed specifically for mirrorless systems.

Wait, how does this affect your experience?

You’ll find that the E-PL1s supports newer, more compact lenses perfect for travel and street photography, with more contemporary features like optical image stabilization built into lenses. The E-420, though compatible with many pro-grade lenses, tends to force bulkier setups.

The lens mount difference also impacts autofocus performance - lenses designed for Micro Four Thirds tend to focus faster and quieter thanks to modern motors optimized for mirrorless autofocus.

Simply put, the E-PL1s wins lens versatility and future-proofing for the Micro Four Thirds mirrorless system, making it a more flexible platform for creative experimentation.

Video Capabilities: Modest at Best, but Worth Noting

Back in 2008-2010, video was an afterthought for entry-level Olympus cameras, and these two models are no exception.

• E-420: No video recording ability.
• E-PL1s: Offers basic HD video recording at 1280 x 720 resolution, 30 fps, using the MJPEG codec.

While the E-PL1s’s video quality is serviceable for casual use, don't expect cinematic results. No microphone or headphone jacks means audio quality can be limited. However, the presence of HDMI output on the E-PL1s is a nice bonus for video monitoring or playback on a larger screen.

If video is a significant part of your photography lifestyle, the E-PL1s is a modest step up, but today’s entry-level mirrorless cameras offer far superior video specs and stabilization.
