Canon M5 vs Panasonic Lumix S5 II: An In-Depth Mirrorless Camera Showdown

Choosing between two mirrorless cameras from such different eras and categories - the 2016 Canon EOS M5 and the 2023 Panasonic Lumix DC-S5 Mark II - is like comparing a seasoned sprinter to a marathon runner: both are strong athletes but built for different races. Having spent countless hours testing both vintage and state-of-the-art cameras under diverse shooting conditions, I’m excited to guide you through a rigorous side-by-side evaluation of these two compelling options.

In this comprehensive review, I’ll cover the key aspects that matter most to serious photographers and advanced enthusiasts alike - from sensor technology, autofocus prowess, and ergonomics to real-world performance across major photography disciplines. By the end, you’ll have a clear understanding of how each camera stacks up for portrait work, landscapes, wildlife, video, and much more.

Let’s dive in.

A Tale of Two Generations and Sensor Sizes

First off, let’s get the fundamental differences on the table. The Canon M5 is an APS-C mirrorless camera aimed at advanced enthusiasts, whereas the Panasonic S5 II is a full-frame, pro-oriented mirrorless with a hefty feature list and a correspondingly higher price tag.

Sensor Technology and Image Quality

The Canon M5 houses a 24.2-megapixel APS-C CMOS sensor measuring 22.3 x 14.9 mm. By 2016 standards, the M5’s Digic 7 processor combined with this sensor yielded reasonably strong image quality, especially for casual shooting and social media-sized prints. The built-in anti-aliasing filter helps smooth out moiré but also slightly softens images - a classic compromise.

In contrast, the Panasonic Lumix S5 II packs a 24.2 MP full-frame sensor (35.6 x 23.8 mm) without an anti-aliasing filter. This sensor offers substantially more imaging area (nearly 2.5x the surface of the Canon APS-C chip), meaning improved low-light performance, wider dynamic range, and shallower depth-of-field control. Panasonic’s new sensor supports extended ISO up to 204,800 (boosted), which is way beyond the M5’s maximum native ISO of 25,600.

I’ve tested both cameras in low-light and high dynamic range scenarios, and it’s clear the S5 II’s sensor dominates in delivering cleaner, more detailed images with richer tonality, especially at high ISOs.

Technical Image Quality Metrics

According to DxOMark data, the M5 scores a respectable 77 overall, with a color depth of 23.4 bits and 12.4 EV dynamic range at base ISO. While the S5 II has not been tested on DxOMark at the time of writing, Panasonic’s full-frame sensor technology lineage clearly puts the S5 II near or beyond the upper echelon in these categories based on related sensors in the S5 and S1 series.

Body Design and User Interface: Handling That Makes a Difference

Both cameras feature an SLR-style mirrorless body, but ergonomics and controls vary considerably.

Canon M5: Compact but Without Weather Sealing

The M5, weighing just 427 grams and measuring 116 x 89 x 61 mm, is a compact option with a comfortable front grip for its class. The 3.2" tilting touchscreen is responsive and integrates touch AF well, a boon for quick composition and focus point selection.

However, the M5 lacks any environmental sealing and features no image stabilization in the body - a limitation to consider if you shoot in harsher conditions or rely on stabilized lenses.

Panasonic S5 II: Robust and Weather-Sealed

The S5 II is a bigger beast at 740 grams and 134 x 102 x 90 mm, offering a more substantial grip and a fully articulated 3" touchscreen with a higher resolution (1840K dots). Its fully weather-sealed body makes it far more suitable for demanding professional use, including landscapes and outdoor shoots in varied climates.

Beyond size and weight, Panasonic’s design includes dual SD card slots for redundancy or overflow - critical for pros who can’t compromise on storage reliability. The inclusion of USB 3.2 Gen 2 for blazing data transfer rates also speaks to its professional pedigree.

Autofocus Performance: Precision and Tracking Matter Across Genres

Autofocus (AF) technology has evolved substantially since 2016. The M5 incorporates Canon’s hybrid AF system with both phase-detection and contrast-detection points - a total of 49 AF points, which covers a moderate portion of the frame.

The S5 II boasts a staggering 779 AF points, employing advanced deep learning algorithms for eye and face tracking in humans and animals - a critical upgrade that directly boosts portrait, wildlife, and action photography performance.

I ran extensive AF speed and accuracy tests under various lighting and movement conditions. The M5 delivers competent AF in controlled environments but struggles with fast-moving subjects or complex patterns, especially in continuous AF mode.

The S5 II, by comparison, shines with near-instantaneous focus lock and tracking, even when subjects sprint or flutter unpredictably. The addition of animal eye detection extends Panasonic’s versatility for wildlife photographers who demand reliable focus on fast or erratic subjects.

Burst Shooting and Buffer: Sport and Wildlife Photography

Both cameras offer a top continuous shooting rate of 9 fps using mechanical shutter, quite impressive for the M5’s class and vintage, but the S5 II complements it with 30 fps burst shooting using electronic shutter mode.

This combination of fast frame rates and advanced AF tracking makes the S5 II a genuine contender for sports and wildlife shooters needing to capture extensive sequences with confident subject tracking.

Video Capabilities: Getting Serious Beyond Stills

Video shooters will find the Canon EOS M5 rather limited - it maxes out at 1080p at 60fps. While decent for casual use and vlogging, demanding videographers will quickly feel constrained.

Panasonic’s S5 II, however, features state-of-the-art 6K and 4K video recording at up to 60fps with both H.264 and H.265 codecs. The S5 II also offers professional audio input options, including microphone and headphone jacks, plus robust 5-axis sensor stabilization that drastically improves handheld video quality.

If you are a hybrid photographer/videographer - or seriously into video work - the S5 II is a no-brainer.

Specialized Photography Disciplines: What Works Best Where?

Portrait Photography

The Canon M5’s APS-C sensor inherently offers greater depth of field compared to full-frame - less ideal for isolating subjects with buttery bokeh. Its 49-point AF system includes face detection but lacks animal eye detection and sophisticated tracking.

In strict portrait scenarios, shallow depth-of-field, accurate eye AF, and skin tone rendering are paramount. The Panasonic S5 II excels here: its larger sensor, advanced AF, and natural color science deliver superior results. Moreover, I’ve found the S5 II’s fully articulating screen an added bonus for creative angles or self-portraits.

Landscape Photography

Landscape photographers benefit from dynamic range, resolution, weather sealing, and tripod-use features.

While the M5 delivers respectable 24MP resolution, its dynamic range and base ISO noise floor trail behind the Panasonic’s full-frame sensor. The S5 II’s weather sealing and dual card slots add peace of mind for long hikes or remote locations. Panasonic’s ability to shoot in focus stacking or bracketing modes out of the box is a feature the Canon M5 misses entirely.

Wildlife Photography

Faster AF, bigger buffer, more reliable tracking, and the benefit of full-frame sensor noise performance all place the Panasonic S5 II leaps ahead of the M5 in wildlife photography.

The advanced autofocus system, 30 fps electronic shutter burst, and animal eye AF software on the S5 II collectively mean you won't miss fleeting moments or critical focus points - especially important with fast-moving birds or mammals.

Sports Photography

Much like wildlife, sports demand rapid autofocus, high frame rates, and excellent low-light capability. The M5’s 9 fps max and mid-range AF system may suffice for casual sports but struggle in dim stadiums or with fast action.

The S5 II’s 30 fps burst in electronic shutter mode and eye/face tracking deliver a professional-level toolkit for most sports. The improved flash sync speed (250 ms vs. 200 ms) also lets you balance ambient and flash lighting creatively.

Street Photography

Here, discretion, portability, and quick operation count.

The Canon M5’s smaller size and lower weight make it excellent for street photographers who want a discreet, quick-reacting camera that won’t draw attention.

The Panasonic S5 II’s larger size and weight may slow you down on crowded streets, but its improved high ISO and autofocus performance pay dividends at night or in challenging light.

Macro Photography

Neither camera is primarily focused on macro, but Panasonic edges out due to sensor stabilization and focus bracketing/stacking features that the M5 lacks.

I have shot macro handheld with the S5 II using its 5-axis sensor stabilization, achieving sharp results at slower shutter speeds. If macro is a significant part of your workflow, these features prove handy.

Night and Astro Photography

Shooting the night sky tests a camera’s low noise, long exposure stability, and star tracking capabilities.

The Canon M5’s native ISO and dynamic range limit low-light performance, though it remains usable in controlled situations. The S5 II’s full-frame sensor, extended ISO range, and fast shutter options (up to 1/8000s) allow capture of detailed starscapes with less noise.

Further, the S5 II offers higher ISO flexibility and electronic shutter silent operation, important for astrophotographers who want to avoid vibrations.

Travel Photography and Versatility

Travel photographers typically juggle weight, battery life, versatility, and ruggedness.

The Canon M5’s compact form factor and lower weight earn significant points here, enabling hours of comfortable handheld operation.

However, its limited battery life (around 295 shots per charge) and lack of weather sealing may reduce its reliability in demanding travel scenarios.

Meanwhile, the Panasonic S5 II, although notably heavier (740g), provides better battery longevity (~370 shots), a more versatile lens mount ecosystem (over 65 lenses compared to Canon’s 23 EF-M lenses), and weather sealing - all valuable for serious travel photographers who value reliability over compactness.

Professional Work and Workflow Integration

For full-time professionals, the camera needs to deliver reliability, high-quality file formats, and smooth integration into existing workflows.

The Panasonic S5 II proves superior with its dual card slots, powerful USB 3.2 interface, extensive video options, and better build quality. It supports both raw capture and post-capture focus stacking/bracketing, making it more future-proof.

The Canon M5 fulfills many enthusiast needs but falls short of professional standards in backup options and weather sealing.

Build Quality, Battery, and Connectivity

The M5’s lightweight design feels pleasant in hand but lacks environmental sealing. Battery life, at 295 shots, is modest for a mirrorless but typical at its time.

The S5 II shines again - weather sealed, with improved dimensions and a beefier battery that lasts around 370 shots per charge. Dual SD slots and cutting-edge connectivity options (including Wi-Fi and Bluetooth) make it suitable for modern workflows.

Value and Price-to-Performance Analysis

At launch, the Canon M5 hovered around $680 - a compelling price for APS-C enthusiasts wanting an advanced mirrorless with solid image quality and classic Canon colors.

The Panasonic S5 II carries a significantly higher cost ($1,999), reflecting its pro-level full-frame sensor, advanced AF, and video features.

If budget is a primary concern and your shooting ambitions are moderate or casual, the M5 remains a sensible choice. But for those demanding flexibility, cutting-edge tech, and professional-grade video and photo capabilities, the S5 II represents exceptional value for the money in the current mirrorless landscape.
