Olympus E-M5 vs Panasonic ZS35: A Deep Dive Into Two Different Worlds of Photography

Choosing the right camera is often a balancing act between your photographic ambitions and budget constraints. Today, I’m teaming up two distinctly different cameras that share a few specs but aim at almost opposite user types: the Olympus OM-D E-M5, a stylish advanced mirrorless with a Micro Four Thirds sensor, and the Panasonic Lumix DMC-ZS35, a compact superzoom with a small 1/2.3" sensor.

Having spent years testing hundreds of cameras in studios, in the wild, and everywhere in between, I’m going to walk you through how these two stack up across a spectrum of photographic disciplines - from portraiture to nightscapes. My goal? To help you figure out which camera fits your style and shoot priorities best, whether you’re upgrading your kit or stepping out of smartphone territory for the first time.

Let’s get hands-on - literally.

Size and Handling: Ergonomics Matter When You Shoot

Before we get into specs and pixel peeping, a reality check: the camera has to feel good in your hands. Olympus designed the E-M5 to be an SLR-style mirrorless, borrowing from DSLR ergonomics, while the Panasonic ZS35 is all about compact convenience with a small “point-and-shoot” form factor.

At 122x89x43mm and 425g, the Olympus E-M5 is substantial but not unwieldy. The grip is sculpted to give you control during extended sessions, which photographers will appreciate, especially in fast-paced shooting scenarios. The magnesium alloy body also ensures durability and a certain "club-for-your-thumb" robustness.

The Panasonic ZS35, by contrast, weighs just 305g and measures a compact 107x62x32mm. It fits comfortably in a jacket pocket or small bag, making it a low-friction travel companion. Handling is minimalistic, with fewer control clubs to fuss over - almost too streamlined for manual control, but perfectly designed for point-and-shoot convenience.

For those who prize manual control and grip comfort, the E-M5 leads. If portability is king, especially for travel and street photography, the ZS35 wins here hands down.

Design and Controls: A Tale of Two Interfaces

Looking closer at how each camera communicates with its user:

The Olympus E-M5 sports dedicated dials for ISO, exposure compensation, and shooting modes - clubs for your thumbs that let you tweak settings on the fly without diving into menus. The tilting touchscreen LCD (3 inches, 610k dots) offers additional intuitive control. The OLED electronic viewfinder (EVF) is a bright, 1440-dot window that replaces an optical finder nicely, critical when shooting in bright outdoors or wanting precise framing.

Meanwhile, the Panasonic ZS35 relies on a single dial and a handful of buttons, paired with a tilting (but non-touch) 3-inch LCD with lower resolution (460k dots). No electronic viewfinder here, which can be a dealbreaker if you prefer eye-level composition or want better visibility in sunlight.

From a usability standpoint, the E-M5 offers hands-down better tactile control, customizable buttons, and a killer EVF - features that make manual shooting a joy for enthusiasts and pros alike. The ZS35’s simpler interface suits newcomers or those who want minimal fuss, especially if you mostly shoot in auto modes.

Sensor and Image Quality: Size Matters (A Lot)

This is the moment many enthusiasts wait for: how do these cameras perform where it counts - image quality?

The Olympus uses a Micro Four Thirds 17.3x13mm CMOS sensor with a 16MP resolution, packing considerably more imaging real estate (about 225mm²). The sensor is paired with Olympus’s TruePic VI processor, enabling strong color depth, dynamic range, and noise control.

DxO Mark scores back this up: the E-M5 earned an overall 71, with 22.8 bits of color depth and 12.3 EV in dynamic range. Low-light ISO performance is solid for its class, rated at 826.

In contrast, the Panasonic ZS35’s 1/2.3-inch sensor is just 6.08x4.56mm (about 28 mm²), also 16MP but smaller pixels. This size limits noise handling and dynamic range. The smaller sensor achieves basic image quality but suffers from more noise at ISO 800 and above; high dynamic range scenes tend to lose shadow and highlight details.

For serious image quality, the Olympus E-M5’s bigger sensor gives it a massive advantage in color reproduction, detail sharpness, and noise control - factors especially critical for portraits, landscapes, and professional uses. Panasonic’s ZS35 is a convenient snapshooter and daylight performer, but it won’t stand up in low light or high-contrast scenarios.

LCD and Viewfinder: Framing Your Shot With Confidence

Handling bright outdoor light or tilting to get creative angles? The screens and viewfinders matter day-to-day.

The Olympus E-M5’s 3-inch articulating touchscreen OLED with 610k dots offers vibrant colors, deep blacks, and a responsive interface. It facilitates touch autofocus and menu navigation, speeding up operation significantly. The tilting mechanism is versatile, good for low or high-angle work.

The Panasonic ZS35’s 3-inch 460k TFT LCD tilts 180 degrees, useful for selfies or overhead shots, but it’s non-touch and notably dimmer with less contrast. No EVF is a limitation in bright conditions, where LCD glare can hinder composition.

Users needing precise framing and touch control get more out of the Olympus, while the Panasonic’s screen suffices for casual use but frustrates if you shoot outdoors a lot or want fast manual focus.

Autofocus and Burst Performance: Catching Action and Sharp Focus

Whether photographing kids, wildlife, sports, or fleeting street moments, autofocus speed and accuracy combined with burst shooting capability can make or break the image.

The Olympus E-M5 offers a contrast-detection AF system with 35 focus points and face detection. While contrast AF isn’t as lightning-fast as phase detection, Olympus’s processing optimization results in reliable and reasonably quick focus acquisition, even in lower light. The camera achieves 9 frames per second continuous shooting in burst mode - impressive for its class and enough for many action scenarios.

The Panasonic ZS35 uses contrast AF with 21 focus points and face detection but no touch AF. Its burst speed edges slightly higher at 10 fps, though the buffer fills quickly and image quality takes a hit at the fastest settings.

In real-world usage, the Olympus’s AF system gives better accuracy and consistent tracking, especially for moving subjects, despite not having phase detection. If sports or wildlife photography is your focus, the E-M5 clearly provides more reliability and control.

Lens Ecosystem: The Power of Interchangeability

Lens choices define what styles and quality you can achieve beyond sensor specs.

The Olympus OM-D E-M5 features the Micro Four Thirds (MFT) mount, meaning compatibility with a mature lens ecosystem with over 100 native lenses ranging from ultra-wide primes, fast portraits, rugged macros, and even professional telephotos. This lens flexibility spans quality and price points, allowing shooters to grow and specialize.

The Panasonic ZS35 is a fixed-lens superzoom - a 24-480mm (20x) equivalent with variable aperture f/3.3-6.4. You can’t swap lenses or upgrade optics; your creative options remain bound to this one zoom range and quality level.

For serious photographers or those seeking versatility, the E-M5’s lens system utterly outclasses the ZS35. The latter is a convenient all-in-one but a static tool, especially limiting in low light or portrait bokeh effects.

Build Quality and Weather Sealing: Can Your Camera Tough It?

If you shoot outdoors, durability and weather resistance are significant considerations.

The Olympus E-M5 has a magnesium alloy body with environmental sealing against dust and splash, making it a solid companion for travel, landscapes, and rugged shoots. It's splashproof but not fully waterproof or shockproof.

The Panasonic ZS35 lacks any weather sealing or ruggedization. Its plastic body is fine for casual use but vulnerable to elements and rough handling.

Hence, for photographers who need a durable workhorse, the Olympus wins points and reliability.

Battery Life and Storage: Staying Powered on the Go

How long can you shoot before chasing for a charger or swapping cards?

The Olympus E-M5’s battery (BLN-1) offers roughly 360 shots per charge under CIPA standards. Decent but on the lower side compared to DSLRs - typical for mirrorless cameras of its time.

The Panasonic ZS35 battery life is unspecified, but small sensor compacts often achieve upwards of 350-400 shots due to efficient electronics.

Both cameras use single SD/SDHC/SDXC slots.

For travel shooters, both are manageable but you might want spares for extended trips; the Olympus charges via proprietary batteries, so bring extras if you’re off grid.

Video Capabilities: More Than Still-Wide Options

Video is an increasingly important feature for many buyers.

The Olympus E-M5 shoots Full HD 1080p at 60fps in H.264 and Motion JPEG formats. It includes 5-axis in-body image stabilization (IBIS), producing smooth handheld video without external rigs - even in less-than-ideal conditions. While it lacks microphone or headphone jacks, the quality and stabilization are robust for its vintage.

The Panasonic ZS35 also records Full HD 1080p but only at 30fps, using MPEG-4 compression. It uses optical stabilization integrated into the lens but lacks IBIS. No external audio support.

For video creators wanting stable, high-quality footage, the Olympus E-M5 is the better pick. The Panasonic is fine for casual clips but may disappoint videographers looking for flexibility and smoothness.
