Olympus E-PM2 vs Olympus SP-620 UZ

Olympus E-PM2 vs. Olympus SP-620 UZ: A Hands-On Comparison for Enthusiasts and Pros

In my fifteen years of camera testing, few things are as telling as stacking two Olympus cameras side-by-side and digging deep into what each truly delivers in everyday shooting. Today, I’m comparing two intriguing models from Olympus released within a year of each other: the mirrorless Olympus PEN E-PM2 and the compact superzoom Olympus SP-620 UZ. Though each belongs to different categories - entry-level mirrorless and small sensor superzoom compact respectively - they both woo buyers on a budget seeking versatile shooters. Through extensive hands-on trials and technical analysis, I’ll guide you through everything you need to know to decide which’ll serve you better.

Setting the Stage: Understanding What They Are and Who They’re For

The Olympus E-PM2 is a Micro Four Thirds (MFT) mirrorless camera launched in mid-2013 as an evolution from the E-PM1. As a rangefinder-styled mirrorless, it targets users stepping up from point-and-shoot cameras or smartphones with a desire for interchangeable lenses, manual control, and superior image quality. Its compactness and approachable ergonomics invite a broad audience - from landscape and portrait photographers to travel enthusiasts.

The Olympus SP-620 UZ is a small-sensor, fixed-lens superzoom compact released a year earlier in early 2012. Weighing almost twice as much as the E-PM2 and sporting an impressive 21x optical zoom, it's an all-in-one solution aimed at casual shooters who want reach without swapping lenses, particularly useful for travel and wildlife photography on a budget.

My testing focused on practical performance across the main photography genres and real-world scenarios, supported by technical data from DxOMark and prolonged shooting sessions in varied environments.

First Impressions: Design and Handling

Before even firing up the shutter, how a camera feels in hand often dictates whether you’ll enjoy shooting it for hours - which is critical whether you’re out on a portrait session or hiking with gear in tow.

The E-PM2 is a neat little package (110x64x34mm, 269g) that fits comfortably in average to small hands, but expect to rely on extra grip accessories for prolonged handheld shooting or heavy lenses. It sports a rangefinder style body with traditional controls, giving tactile feedback that I appreciate from my years shooting mirrorless systems.

Comparatively, the SP-620 UZ, while compact for a superzoom, is bulkier and heavier (110x74x74mm, 435g) and feels a bit more plasticky in hand. Its thick 21x zoom lens extends quite far, but the fixed layout means no interchangeable lens magic. Handling is straightforward but less refined - there’s no viewfinder, and the LCD screen doesn’t offer touch features, making menu navigation slower.

This size-and-weight difference is fundamental: the E-PM2 is more pocketable and versatile, while the SP-620 UZ is a go-to when you want stellar reach plus simplicity.

Controls and Interface: Navigating Your Creative Flow

Good cameras anticipate your shooting flow with well-placed buttons and responsive screens.

The E-PM2’s control layout impressed me with its pragmatic approach. While entry-level, it features physical dials for exposure modes including aperture priority, shutter priority, and manual exposure - vital for serious photographers to shape images creatively. The camera offers an intuitive 3-inch touchscreen (460k-dot resolution) on a fixed display, blending touchscreen convenience with tactile button controls.

By contrast, the SP-620 UZ has fewer physical controls - focused on ease-of-use rather than granular control - with no manual exposure mode, no touch capability on its lower-resolution 3-inch LCD (230k dots), and a rather dated menu design. For experienced users, this limitation can be stifling, but casual shooters will likely appreciate the simplicity.

If you enjoy peering through a viewfinder, neither camera offers an integrated EVF. The E-PM2 supports an optional electronic viewfinder (sold separately), a sensible upgrade path. The SP-620 UZ relies fully on its rear LCD for composition, adequate in bright conditions but frequently frustrating under sunshine.

Sensor and Image Quality: The Heart of the Matter

Any camera’s image quality hinges largely on its sensor, processing, and lens system. Here, the specifications and DxOMark numbers reveal a substantial gulf.

The Olympus E-PM2’s Micro Four Thirds sensor (17.3x13 mm) boasts a respectable 16MP resolution and an antialiasing filter, offering highly detailed 4608x3456 pixel images. According to DxOMark, it posts an overall score of 72, with 22.7 bits of color depth and an excellent 12.2EV dynamic range at base ISO. Its low-light ISO score of 932 translates to practical usable performance at ISO 1600–3200 in real-world shooting, particularly paired with in-body sensor-shift stabilization.

On the other hand, the SP-620 UZ’s tiny 1/2.3" CCD sensor (6.17x4.55 mm) shares the same 16MP count but struggles physically with much smaller pixels and less light-gathering capability. DxOMark data isn’t available for this model, but experience and historical testing suggest it’s closer to entry-level compact quality - especially in dynamic range and high ISO noise. Max ISO is limited to 3200, but usable image quality deteriorates sharply above ISO 800.

This smaller sensor gain less depth and highlight retention, constraining photographers looking to pull detail out of shadows or shoot in low light with confidence.

Autofocus and Shooting Performance: Catching the Moment

Autofocus speed and accuracy can make or break the experience - whether tracking athletes or freezing fleeting wildlife behavior.

The E-PM2 uses a contrast-detection autofocus system with 35 focus points and face detection, which I found responsive and precise in good light, able to keep pace with moving children and pets indoors or in daylight. Continuous AF and tracking work reasonably well but lag behind modern mirrorless cameras with phase detection. However, its 8 fps burst rate gives a nice edge in capturing fast action sequences.

The SP-620 UZ employs contrast detect only as well, though with a much more basic focus system and fewer focus points (exact number undisclosed). It is significantly slower to lock focus, especially at long zoom, and does not support manual focus - limiting creative control. Continuous autofocus and burst shooting are absent, so it’s best suited to posed or slow-action shooting.

Autofocus performance becomes critical in wildlife and sports scenarios, and here, the E-PM2 clearly takes the win.

Lens Choices and Versatility

The Olympus E-PM2’s Micro Four Thirds mount grants access to an extensive, mature lens ecosystem - with over 100 lenses covering primes, zooms, macros, and specialty optics. This translates into creative freedom for every genre, from fast 45mm f/1.8 portraits to versatile travel zooms and weather-sealed options for landscapes.

In contrast, the SP-620 UZ’s fixed zoom lens (25-525mm equivalent, f/3.1-5.8) serves as an all-in-one with great reach but limited brightness and no possibility to swap lenses for creative effect or specialized tasks.

This difference becomes a decisive factor for photographers favoring long-term system growth and lens quality.

Build Quality and Weather Sealing

Neither camera features weather or environmental sealing, so caution is advisable shooting in rain or dusty conditions. The E-PM2’s metal and plastic body feels sturdier and more substantial than the mostly plastic body of the SP-620 UZ, which is light but less robust.

For outdoor photographers who encounter elements, investing in weather sealing or protective gear is recommended for both.

Battery Life and Storage Flexibility

Battery performance varied significantly in my tests. The E-PM2’s proprietary BLS-5 battery offers around 360 shots per charge under typical shooting, which I found adequate for day shoots but requiring spares for extended fieldwork.

The SP-620 UZ runs on 4 AA batteries, a plus for travelers without access to recharging - especially useful during remote excursions - but the overall battery life tends to be shorter and AA rechargeables are a must for cost efficiency.

Both cameras use SD/SDHC/SDXC cards and have a single card slot, simplifying storage management but limiting on-the-fly backup options.

Video Capabilities: What’s on Offer?

The E-PM2 provides Full HD 1080p video at 30 fps, recorded in MPEG-4, H.264, and Motion JPEG formats. It includes basic exposure controls during video and sensor-based image stabilization, contributing to smoother footage. However, there’s no microphone input or headphone output, limiting external audio control.

The SP-620 UZ tops out at HD 720p video at 30 fps, with no external mic support and more limited exposure controls, making it a secondary shooter for video.

If hybrid photo/video shooting is on your agenda, the E-PM2’s video specs offer more creative latitude.

Connectivity and Extras

Both cameras support Eye-Fi wireless compatibility for transferring images over Wi-Fi with compatible cards, but neither includes Bluetooth or NFC, and neither has built-in GPS - features expected on more contemporary cameras.

The E-PM2 has an HDMI port and USB 2.0 connectivity, while the SP-620 UZ offers similar physical ports, though the newer processing capabilities of the E-PM2 deliver faster transfer speeds and better integration into modern workflows.
