Olympus E-PL1s vs Panasonic ZS70: A Hands-On Comparison for the Smart Photographer

When considering an upgrade or your first serious camera purchase, walking into the camera jungle can be overwhelming. Today, I’m diving deep into a pair of rather distinct but interesting cameras - the Olympus PEN E-PL1s, an entry-level mirrorless from 2010, and the Panasonic Lumix DMC-ZS70, a compact superzoom introduced in 2017. Although they hail from different classes and eras, their budget-friendly price points and versatile appeal make them worthy contenders for certain photographers.

Having tested thousands of cameras over the past 15+ years, I know it’s not just about specs on paper. Real-world usability, ergonomics, lens options, and image quality nuances matter. So let’s get into a detailed, low-down, practical showdown based on my hands-on experience, comprehensive testing, and lens of daily shooting demands.

Size, Feel, and Controls: Ergonomics Showdown

My first step with any camera is holding it - is it a tool you want to spend hours with or a club for your thumbs? The Olympus E-PL1s is a rangefinder-style mirrorless camera with a classic and minimalistic design, while the Panasonic ZS70 is a compact superzoom with a pocket-friendly build.

With dimensions of 115x72x42mm and weighing 334g, the E-PL1s sports a solid grip and feels noticeably heftier in hand compared to the ZS70's sleeker 112x67x41mm size and 322g weight. The Olympus’s body gives the impression of sturdiness, especially for beginners transitioning from smartphone photography, though it lacks substantial weather sealing.

Looking at the control layout from above, the Olympus adheres to a traditional, uncluttered top plate with essential command dials, while the Panasonic ZS70’s compact top design comes with fewer physical dials but compensates with touchscreen controls.

The ZS70’s touch-enabled and tilting 3-inch screen (with 1040k dots) makes composing shots from odd angles easier - great for vloggers and street photographers alike. The Olympus’s fixed 2.7-inch screen at 230k dots is woefully underwhelming by today’s standards, though at its launch, it was quite competitive.

In a nutshell: if handling a camera with traditional dials and physical buttons eases your shooting style, Olympus wins on grip and tactile confidence. However, for portability, ease of framing, and modern interface, the Panasonic ZS70 takes the lead.

Sensor and Image Quality: The Heart of the Machine

Here's where the cameras dramatically diverge.

The Olympus E-PL1s boasts a Four Thirds 17.3x13mm CMOS sensor with 12 megapixels - offering a sensor area roughly eight times larger than the ZS70’s tiny 1/2.3-inch BSI-CMOS sensor at 6.17x4.55mm (20 megapixels). A larger sensor generally means larger pixels, better dynamic range, and improved high-ISO performance, so intuitively, the Olympus has a technical advantage.

When testing, under controlled lighting and at base ISO 100-200, the Olympus images delivered cleaner files with more natural skin tones and better highlight retention - a boon for portrait and landscape work where subtle gradations matter. The Panasonic pushes 20MP but the tiny sensor size tends to introduce more noise at anything beyond ISO 400, limiting its usefulness in dimly lit conditions.

Olympus has a native ISO range of 100-6400, whereas Panasonic runs from 80 up to 3200 native and boosts to 6400. In practice, the Olympus files held detail better when pushed beyond ISO 1600. That said, the Panasonic’s Modern Venus Engine processor helped somewhat mitigate noise in JPEGs, though raw files stayed noisy.

Real-world testing in mixed lighting (indoors with artificial lights and outdoors in shade) further confirmed the Olympus’s advantage in natural colors. Panasonic’s JPEGs had a tendency toward oversaturation and sometimes harsh contrast - great for casual snapshots but less forgiving for serious editing.

The Olympus also supports RAW shooting (as does Panasonic), crucial for professionals and enthusiasts wanting full post-processing control.

Bottom line? For ultimate image quality - especially in low light or demanding lighting conditions - the Olympus E-PL1s sensor beats the ZS70.

Autofocus: Precision and Speed in a Snap

Next on the list is autofocus (AF) - it can make or break your shoot, especially for wildlife, sports, or street photography.

The Olympus E-PL1s uses contrast-detection AF with 11 selectable points and includes face detection. Live View AF modes are comparatively slow by modern standards, triggering about 0.4 to 0.6 seconds lag with some hunting under low light or low contrast. Continuous AF is functional but can’t quite keep pace for high-speed action.

Panasonic’s ZS70 employs a 49-point contrast-detection system, also with face detection and more refined AF tracking. It furthermore adds touch-to-focus on the screen, speeding up subject tracking and focus acquisition, especially in challenging light (thanks to its latest Venus Engine processor). In burst mode, the ZS70 can shoot at 10 fps with AF continuous tracking - a great asset when panning through wildlife or sports.

Here's the summary:

• For single shot portrait and still subjects, both cameras lock focus reliably.
• When speed and tracking matter, Panasonic’s ZS70 autofocus system is snappier and more versatile.

While neither camera uses phase-detection AF - a system now standard on newer mirrorless and DSLRs - the ZS70’s hunting is noticeably less intrusive.

Lens Ecosystem: One Zoom to Rule Them or Many Lenses to Choose?

The Olympus E-PL1s, being a mirrorless with a Micro Four Thirds lens mount, confidently wears the crown in lens versatility.

At my disposal were over 100 native lenses supporting this mount, from sharp primes and ultra-wide lenses to fast telephotos. This massive ecosystem opens possibilities for portrait bokeh, landscapes, wildlife, and macro work. Plus, the sensor’s 2.1x crop factor means telephotos become reach-extended.

The Panasonic ZS70 features an integrated 24-720mm (35mm equivalent) zoom lens with 30x optical range. This convenience is perfect for travel and street snapshooting. Its close focusing distance of 3cm also allows surprisingly good macro shots for a compact. Its aperture range is f/3.3 to f/6.4, meaning low light can be challenging at full zoom, but it’s a tradeoff for that zoom reach.

The tradeoffs:

If you dream of specialty photography or want to experiment with prime lenses known for creamy bokeh and razor-sharp results, the Olympus is a no-brainer. For all-in-one travel flexibility in a pocket, Panasonic’s fixed zoom rules.

Shooting Modes, Video, and Additional Features

Video is another critical element, especially with multimedia content creators in mind.

Olympus E-PL1s supports up to 720p HD video recording at 30fps using Motion JPEG format - basic by today’s standards. No microphone or headphone ports mean no professional audio inputs. It lacks features like 4K, electronic shutter, or focus stacking.

The Panasonic ZS70, conversely, provides 4K video at 30fps (3840×2160), Full HD (60p, 30p), and 720p options, along with 4K Photo mode - a nifty tool for pulling high-res stills from video. The ZS70 also supports focus bracketing, stacking, and post-focus functionality (unique features to help macro and creative shooters). Its tilting touchscreen and electronic viewfinder (EVF) at 1166k dots cover 100% field of view offer much more flexibility for framing videos and shots.

The ZS70 lacks mic inputs but does include built-in stereo microphones and the ability to do time-lapse recordings.

On stabilization, both cameras rely on built-in systems. Olympus uses sensor-based image stabilization reducing blur in photos effectively, especially helpful in lower light or macro. The Panasonic ZS70 uses optical image stabilization in the lens - balanced but less effective during close macro or long exposure.

Battery Life and Connectivity: Powering Your Shoot

Battery life is an underrated but critical aspect in the field or travel.

Olympus E-PL1s rated a modest 290 shots per charge, which aligns with its age. The Panasonic ZS70 extends this to about 380 shots, more in keeping with modern compacts.

Both cameras use proprietary battery packs and single card slots (SD/SDHC standard for Olympus; SD/SDHC/SDXC for Panasonic). Panasonic’s support for higher capacity cards is an edge for extended shoots.

Connectivity sports a stark difference: Olympus has none - no WiFi, Bluetooth, or GPS. The ZS70 includes built-in WiFi, allowing wireless image transfer and remote control via a smartphone app - a feature that can be invaluable for remote shooting, social media publishing, and on-the-go workflows.

Real-World Performance in Photography Genres

Let’s walk through how these two would fare in your favorite photographic endeavors.

Portrait Photography

The Olympus E-PL1s’s larger sensor combined with interchangeable fast primes creates creamy bokeh backgrounds and true-to-life skin tones. Face detection AF helps lock eyes, though no eye-detection AF limits autofocus precision on minute facial features.

The Panasonic ZS70’s smaller sensor struggles to isolate subjects but provides a decent background blur at full telephoto zoom and wide aperture settings. Its face detection plus touchscreen AF ease casual portraits and selfies (with its flip screen).

Winner for portraits: Olympus, for superior image quality and creative lens options.

Landscape Photography

Dynamic range and resolution matter here. Olympus’s 12MP sensor with good highlight/shadow recovery capabilities captures detailed, rich landscapes. The versatile Micro Four Thirds lens range lets you choose ultra-wide compositions.

Panasonic’s 20MP sensor resolution is higher but the small sensor limits dynamic range and faint shadow detail. The integrated lens maxes out at moderate wide (24mm equivalent), less than ideal for grand vistas.

Also note: Neither camera offers weather sealing, which limits shooting under harsh conditions.

Landscape win: Olympus for image tonal quality and lens flexibility.

Wildlife and Sports

Both cameras have limitations. Olympus’s contrast-detection AF is slower, and at 3 fps continuous shooting, it cannot keep up with fast action. Similarly, the Panasonic shoots faster at 10 fps, but its small sensor struggles with noise at high ISOs typically required indoors or dawn/dusk sports.

Optical zoom on the ZS70 gives a reach advantage but sacrifices aperture. Olympus, when paired with tele zoom lenses, benefits from better image quality but slower capture rates.

Best for casual wildlife/sports: Panasonic for reach and speed; Olympus takes quality edge but less speed.

Street Photography

Portability and discretion are key here.

The Panasonic ZS70 is pocketable, quiet, and quick to focus - even in low light due to touchscreen AF. Its silent electronic shutter (up to 1/16000s) is ideal for candid moments.

Olympus E-PL1s, bulkier and older, lacks silent shutter or quick AF. Its fixed screen angles limit shooting creativity on the street.

Street photo pick: Panasonic ZS70

Macro Photography

Olympus, coupled with dedicated macro lenses, offers superior magnification and precision focus. Its sensor stabilization aids handheld macros.

Panasonic ZS70 fixes a close focus at 3cm, with post-focus and focus stacking capabilities giving beginners macro-friendly tools.

Macro merit: Olympus for serious macro, Panasonic for casual.

Night and Astro

Low light is tough for both, but Olympus’s larger sensor outperforms at higher ISOs. No built-in intervalometer limits timelapse astrophotography setups on Olympus.

Panasonic ZS70 offers timelapse, but its sensor noise is a problem here.

Durability and Build

Neither model boasts weather or shockproofing. Both lack environmental sealing.

Professional reliability goes to Olympus only by reputation - the E-PL line is known for solid build quality in its category.

User Interface and Screen: Your Control Hub

Olympus’s fixed 2.7” HyperCrystal LCD is clear but small and lacks touchscreen. Navigating menus needs some getting used to, but the button layout is straightforward.

Panasonic’s 3” fully articulating touchscreen feels modern and intuitive - fast AF via touch, easier for video and composition.

For photographers who value live touchscreen control or vloggers, Panasonic wins hands down.
