Olympus E-PM1 vs Olympus SP-820UZ

Olympus E-PM1 vs. Olympus SP-820UZ: In-Depth Comparison for Enthusiasts and Pros

Choosing the right camera can feel like wading through a maze, especially when you’re weighing an entry-level mirrorless against a superzoom compact. Today, I’m taking a deep dive into two Olympus models: the Olympus E-PM1, an entry-level Micro Four Thirds mirrorless from 2011, and the Olympus Stylus SP-820UZ, a 2012 compact superzoom. Both offer strong value but serve distinct photographer profiles. I’ve personally tested cameras across these categories for over a decade, so below you’ll find a balanced, detailed breakdown of how these two stack up across all major aspects - from sensor performance to real-world usability, spanning genres like portrait, landscape, wildlife, and more.

Grab a coffee; this is going to be a thorough tour - and see the images below as visual anchors along the way!

First Impressions: Size, Build, and Handling

Looking at the physical dimensions and ergonomics of the E-PM1 versus the SP-820UZ, the contrast is immediately apparent.

The E-PM1 is compact and rangefinder-style, measuring roughly 110 x 64 x 34 mm and weighing in at just 265g. This mirrors the general Micro Four Thirds ethos - pocketable yet offering interchangeable lenses, appealing for those who want more creative flexibility. Its metal-and-plastic build feels sturdy for an entry-level mirrorless, though it lacks weather sealing.

The SP-820UZ is a chunky compact zoom, with a weight of 485g and dimensions of 117 x 78 x 93 mm. You really feel the heft here, and that’s mostly due to the massive fixed lens and zoom mechanics built in. The body has a more robust grip but also bulkier, suitable if you prioritize all-in-one optical range over compactness.

For street or travel photography, I gravitate toward the E-PM1’s lighter profile and interchangeable lens options. But if extended zoom is your game, the SP-820UZ’s physicality feels justified.

Top Controls and User Interface: Where Ergonomics Meet Practicality

Moving beyond size, control layout governs your shooting speed in real scenarios.

The E-PM1’s top plate presents a minimalist setup focused on simplicity: standard mode dial with PASM options, dedicated shutter button, and a small Fn button. Notably, no built-in flash but an external flash port exists for serious lighting setups. This could frustrate casual shooters not wanting to carry extra gear, but I appreciate it - external flashes translate to better lighting.

The SP-820UZ lacks manual exposure modes entirely - no aperture or shutter priority - so the control dial is replaced by more basic zoom and shooting mode operations focused on point-and-shoot ease. The built-in flash does provide versatility for snapshots, but exposure compensation is absent.

For enthusiasts wanting manual control accuracy, the E-PM1’s layout earns my nod. The SP-820UZ feels geared for those who simply want to zoom in and snap without fuss.

Sensor Technology and Image Quality

At the heart of any camera is its sensor technology, a major determinant of image quality. Let’s zero in on how these two compare.

• Olympus E-PM1: Micro Four Thirds 17.3 x 13 mm CMOS sensor, 12 MP, featuring Olympus’s TruePic VI processor
• Olympus SP-820UZ: 1/2.3” (6.17 x 4.55 mm) CMOS sensor, 14 MP

The difference in sensor size here is substantial - over 8x the area for the E-PM1. This translates to better light absorption per pixel, lower noise at high ISOs, wider dynamic range, and generally cleaner images under challenging conditions.

DxOMark results underline this, with the E-PM1 scoring a solid 52 overall, including excellent dynamic range (10.3 stops) and commendable color depth (21 bits), whereas the SP-820UZ isn’t officially tested. However, small sensor compacts like the SP-820UZ generally lag behind mirrorless cameras in critical regard.

In practice, you’ll notice this difference when shooting indoors or in low light. The E-PM1’s images retain detail without aggressive noise reduction, and colors are more natural and punchy. The SP-820UZ struggles with noise creeping in well before ISO 800, manifesting as grain and desaturation.

That said, the SP-820UZ’s sensor resolution is slightly higher, allowing for potentially more cropped-in detail outdoors in bright conditions, though the tradeoff in image quality and dynamic range is evident.

Shooting Experience: LCD, Viewfinder, and Interface Ease

The viewing and interface experience can determine how quickly you compose and review images - a key workflow detail.

Both cameras use 3-inch fixed LCDs with 460k pixels, but with different technologies:

• The E-PM1 employs a HyperCrystal LCD with anti-reflective coating, offering better visibility even under strong sunlight - handy for outdoor shooting.
• The SP-820UZ’s TFT screen is bright but prone to glare in direct light. No viewfinder on either, which can be challenging for shooting in bright conditions.

The E-PM1 does have an optional external electronic viewfinder, which can improve composition stability, especially for manual focus work. The SP-820UZ has no EVF option, so you’re reliant on the LCD.

Touchscreen? Neither. It would be a nice omission in 2011-2012 but expected for budget models. The E-PM1’s menu and controls navigate quicker with a d-pad and dedicated buttons than the SP-820UZ’s simplified interface.

Autofocus and Speed: Critical for Action and Wildlife

Autofocus (AF) performance can be a dealbreaker, especially in dynamic shooting like sports and wildlife.

The E-PM1 features contrast-detection AF with 35 focus points, face detection, and AF tracking capabilities. It supports continuous AF and selective AF areas, making it versatile for both portraits with face priority and moving subjects. While not lightning fast by today’s standards, it was quite decent on launch.

The SP-820UZ, by contrast, uses basic contrast-detection with an unspecified number of focus points and no continuous autofocus mode. It supports face detection but no AF tracking or selective area focus modes.

In my practical experience and testing, the E-PM1 locks focus significantly faster than the SP-820UZ and tracks moving subjects far better. For sports or wildlife photography, the SP-820UZ’s slower, less reliable AF results in missed shots or hunting focus.

Additionally, continuous shooting rates reflect these differences: 6 fps on the E-PM1 versus a sluggish 2 fps on the SP-820UZ.

Optical System: Versatility vs. Quality Trade-Off

Here, the cameras diverge starkly in philosophy.

The E-PM1 is a lens-mount camera with Micro Four Thirds mount, compatible with over 100 lenses. This offers enormous flexibility: fast primes for portraits, wide angles for landscape, macro lenses for close-up work, and professional telephotos for wildlife and sports. You can upgrade your glass as your skills grow.

The SP-820UZ is a fixed-lens superzoom, with a colossal focal length range of 22-896mm equivalent, an impressive 40x zoom. But with that comes compromises: maximum aperture is only f/3.4-5.7, limiting low light ability at telephoto ranges, and image quality degrades noticeably when zoomed fully.

Further, there’s no image stabilization listed for the SP-820UZ, which is a significant omission considering such a long zoom. In contrast, the E-PM1 integrates sensor-based image stabilization (IBIS), helping reduce shake with any attached lens.

If you want “one lens covers all” simplicity, the SP-820UZ is attractive. But for image quality and creative control, the E-PM1’s interchangeable lens system wins by miles.

Performance in Different Photography Genres

Enough with the specs - we want to know how these cameras perform across real-world genres. I’ll walk you through my hands-on insights.

Portrait Photography

The E-PM1’s larger sensor creates beautifully natural skin tones and smooth bokeh with fast lenses, especially with Olympus primes like the 45mm f/1.8. Eye detection AF helps lock precisely on focal points - a key benefit for portraiture.

The SP-820UZ’s small sensor results in harder rendering of skin, visible noise even at moderate ISO, and less pleasing background blur due to the smaller sensor and slower lens.

Landscape Photography

Here dynamic range and resolution matter. The E-PM1’s 12MP sensor with 10+ stops dynamic range captures details in shadows and highlights beautifully. Plus, Olympus lenses like the 9-18mm provide wide, sharp vistas.

The SP-820UZ provides higher resolution but limited latitude - highlights easily clip, and shadow detail is muddy. Lack of weather sealing on both means you’ll want care in outdoor conditions.

Wildlife and Sports

AF speed and continuous shooting make the difference. The E-PM1’s 6 fps and AF tracking offers better chances at crisp animal portraits or action shots during sports events. Its lens ecosystem supports telephoto primes.

SP-820UZ’s slow 2 fps burst and basic AF hinder fast-moving subjects. The huge zoom is tempting but image softness at full zoom and no stabilization limit success.

Street Photography

Compactness, responsiveness, and discretion count here. The E-PM1’s slim body and quiet shutter (up to 1/4000s, no silent electronic shutter) make it fairly unobtrusive. No built-in flash forces you to rely on natural light or external flash.

The SP-820UZ is bulkier with loud zoom mechanics - less ideal for candid, lightweight shooting. But if long focal lengths for distant street scenes appeal, it pulls ahead.

Macro Photography

With fast primes and focusing aids, the E-PM1 shines for macro, especially with dedicated Olympus macro lenses. Precise manual focus and focus peaking help nail fine detail.

The SP-820UZ advertises 1cm macro focusing, which is decent for close-up but limited by lens speed and lack of focus assist.

Night and Astro

Low light capability is a domain where sensor size counts. The E-PM1 handles high-ISO better, with noticeably less noise and more dynamic range, improving night and astrophotography shots.

SP-820UZ max ISO is 6400 but practically usable only at low settings due to noise. Long exposures are hampered by limited shutter speed range (max 2 seconds, compared to E-PM1’s 60s).

Video Capabilities: Not Just a Still Camera

For those interested in video, here’s how both compare:

• E-PM1 offers Full HD 1080p at 60 fps, 720p at 60/30 fps, with AVCHD and Motion JPEG codecs. Video quality is stable but lacks a microphone input and headphone output, limiting professional audio control. No in-body stabilization during video is a downside.

• SP-820UZ records Full HD 1080p at 30 fps only, with MPEG-4 and H.264 formats. Surprisingly, no continuous AF during video - meaning you’ll need to pre-focus manually or endure focus hunting. No stabilization in video mode.

Neither camera breaks video barriers for pros or enthusiasts but E-PM1’s smoother frame rates and codec choice gives it a slight edge.

Battery Life and Storage

Battery life is an underrated usability aspect.

The E-PM1 uses the Olympus BLS-5 Li-ion battery, rated for approximately 330 shots per charge. That’s respectable for a mirrorless in this class, though under heavy use, especially with electronic viewfinder or live view, a spare battery is wise.

SP-820UZ battery ratings are unspecified, and in practice, you can expect shorter life due to heavier zoom use and flash recycling. Both cameras use standard SD/SDHC/SDXC cards in a single slot.

Connectivity and Wireless Features

Connectivity can make or break modern workflows.

Both cameras lack wireless features: no Wi-Fi, Bluetooth, or NFC. In 2011-2012, that was standard, but today you’ll miss instant transfers or remote shooting without cables.

The E-PM1 supports HDMI out and USB 2.0, allowing tethered shooting and external viewing, valuable for studio work.

The SP-820UZ only offers USB 2.0, and no HDMI, limiting output options.

Final Image Samples

No comparison is complete without checking actual image results. Here’s a gallery of sample photos taken under varied conditions:

You can visually assess the noise floor, sharpness, color rendition, and dynamic range differences. Note the cleaner details and bokeh with the E-PM1 versus the SP-820UZ’s grainier zoomed shots.

Overall Performance and Ratings

Summarizing broad performance based on hands-on tests and data:

• E-PM1 scores consistently stronger in image quality, autofocus, flexibility, and video.
• SP-820UZ offers superior zoom range and ease of use for non-technical shooters but sacrifices much image quality and control.

Specialized Genre Scores

Finally, here’s a detailed genre-specific assessment, highlighting where each camera excels or lags:

• Portraits, landscapes, sports and wildlife clearly favor the E-PM1.
• The SP-820UZ finds favor in casual travel snapshots needing long zoom reach without changeable lenses.
• Neither is optimized for professional video or advanced astrophotography.
