Canon EOS M5 vs Canon EOS RP: A Hands-On Comparison for Enthusiasts and Professionals

When Canon released the EOS M5 in late 2016, it marked a significant leap for their mirrorless line, blending DSLR-style ergonomics with a compact sensor and a versatile feature set. Fast forward to early 2019, the Canon EOS RP emerged as a compelling entry in the full-frame mirrorless category, promising superior image quality in a surprisingly approachable package. But how do these two cameras stack up against each other when you look beyond the specs sheet - especially if you’re trying to decide which deserves a spot in your kit bag?

Having spent years testing hundreds of cameras across demographics and genres, I’m here to unpack everything you need to know about the M5 and the RP - from ergonomics and image quality, to autofocus prowess and usability in diverse shooting scenarios. Whether you are an enthusiast hunting for the perfect travel companion or a pro evaluating tools for your portrait or wildlife work, I’ll guide you through a detailed, experience-backed comparison.

Unboxing the Physical Experience: Size, Build & Handling

Let’s start with how these cameras feel. The body type of both cameras is very much “SLR-style mirrorless,” which means substantial grips and familiar control layouts, yet the difference in sensor format influences size somewhat.

From the image above, it’s clear the EOS RP is noticeably larger and heavier at 485g compared to 427g of the M5. The RP’s dimensions (133x85x70mm) exceed those of the M5 (116x89x61mm), a reflection of housing a full-frame sensor and the slightly more robust weather-sealed chassis. The RP’s build quality feels more professional; it employs a magnesium alloy top plate and partial weather sealing (water resistant but not waterproof), which the M5 doesn’t offer.

Ergonomically, I tend to prefer the RP’s grip for longer sessions - there’s a reassuring heft and larger grip that helps balance heavier RF lenses, a boon if you use telephotos or portrait primes. The M5, while smaller and lighter, still has a solid feel for its class but can get a bit cramped if you have large hands. Still, its compact footprint makes it ideal for street photography and travel where pocketability counts.

Control Layout and User Interface: Quick Access & Customizability

How a camera handles is as important as what it can capture. Both cameras keep a familiar Canon SLR-esque top plate, but their control layouts take subtly different approaches.

Notice the M5's external mode dial next to the shutter release, which makes switching between manual, aperture priority, shutter priority, and program modes quick and tactile. The RP replaces that with a more dial-centric approach with two control dials but no dedicated mode dial. If you shoot in manual or semi-manual modes a lot, you might appreciate the M5's clearer, one-step mode switching.

Both cameras have electronic viewfinders (EVF) at 2.36 million dots, but the RP offers a slightly higher magnification (0.7x vs no magnification spec on M5), giving a more immersive and clearer composition experience, especially with wider lenses. The back LCD touchscreen on the RP is fully articulated, whereas the M5's tilting screen is somewhat limited in flexibility but sports a higher resolution.

Touch responsiveness is excellent on both, a critical feature for quickly placing focus points or adjusting settings in live view.

Sensor Technology & Core Image Quality

This is where things get interesting. At the heart of the EOS M5 is a 24MP APS-C CMOS sensor, while the EOS RP packs a 26MP full-frame CMOS sensor. This difference is the key to understanding their image capabilities and suitability for various disciplines.

The APS-C sensor on the M5 (22.3x14.9mm) offers decent pixel density and performance for its class, but the RP’s full-frame sensor (35.9x24mm) significantly increases the sensor area (861.6mm² vs 332.27mm²), which translates to superior light gathering ability, dynamic range, and color depth.

• Dynamic Range: The M5 registers around 12.4 EV DR, which is respectable, especially given the sensor size and age. The RP clocks slightly lower at 11.9 EV, but that’s still excellent, particularly in real-world use where full-frame’s tonal smoothness shines.

• Color Depth: Both cameras perform similarly, with the RP having a subtle advantage in capturing nuanced skin tones and deeper hues due to slightly better color depth (24bit vs 23.4bit on the M5).

• Low-light ISO Performance: This is one of the RP’s greatest strengths - its native ISO range extends up to 40,000 (extended to 102,400), whereas the M5 tops out at 25,600. In practical shooting, the RP maintains usable image quality well into high ISO values, making it a more reliable tool in dim environments such as weddings, indoor sports, and astro photography.

You will find in my extensive tests, the RP’s images display cleaner shadows with less luminance noise, especially in RAW processing workflows. The M5, while capable, tends to exhibit more noise and aggressive noise reduction that can erase fine detail.

Autofocus Systems: Precision, Speed, and Tracking

Autofocus (AF) can make or break your shooting experience, particularly for wildlife, sports, and portraiture.

• The Canon M5 employs a dual pixel CMOS AF system with 49 focus points, all of which support face detection and continuous tracking, blending phase-detection and contrast-detection technologies.

• The Canon RP, being a newer model, boasts a remarkable 4779 autofocus points (via dual pixel CMOS AF as well, but spread densely across the frame) and faster Digic 8 processing.

Despite the enormous difference in point quantity, the key question is whether this translates into practical gains. During my real-world tests on fast-moving subjects and wildlife in complex lighting, the RP consistently showed better continuous AF tracking and focus lock, especially when combined with Canon’s latest RF lenses with faster autofocus motors. The M5 holds up well, too, but tends to lag slightly in predictive tracking and focus stability during long burst shooting.

For portraits, both cameras shine with dependable eye detection (though neither has dedicated animal eye AF), but the RP again has an edge in speed and accuracy, helpful when subjects move subtly.

Shooting Speed and Buffer Performance

Continuous shooting is a critical metric for sports and wildlife shooters:

• The M5 offers a brisk 9fps burst rate, impressive for an APS-C mirrorless at the time of its release.

• The RP is slightly slower, topping at 5fps, which may disappoint action shooters somewhat.

However, because the RP captures larger RAW files and offers more AF points, you might accept the slower rate for greater file quality and AF confidence.

Video Capabilities: Full HD vs 4K Realities

If video is key for your work or hobby, the video specifications are a stark difference:

• The M5 shoots Full HD (1920 x 1080) up to 60fps in MP4, with a bit rate around 35 Mbps. There is no 4K video support.

• The RP ups the ante with 4K UHD capture at 24fps, 120 Mbps, though it comes with a 1.7x crop and no Dual Pixel AF in 4K mode.

Both cameras supply microphone inputs, but only the RP includes a headphone jack for audio monitoring, essential for serious video work. The RP's fully articulated touchscreen also favors vloggers or run-and-gun filmmakers.

If your video ambitions are primarily Full HD social media clips or amateur cinematic efforts, the M5 suffices. But for 4K recording or professional video capture, the RP’s specs offer more flexibility, despite some limitations.

Lens Ecosystem and Compatibility

Both cameras use Canon’s proprietary mounts, but with different lenses:

• The M5 uses the EF-M mount, with 23 native lenses available (mainly APS-C optimized primes and zooms), but this ecosystem is relatively limited compared to Canon’s bigger systems. You can use EF and EF-S lenses with an adapter, but at the cost of added bulk and sometimes less optimal autofocus performance.

• The RP uses the RF mount, Canon’s newest full-frame lens system, with 17 native RF lenses are currently on the market - many with outstanding optical designs. It also accommodates EF and EF-S lenses fully via an adapter, retaining autofocus speed and image stabilization.

For photographers looking ahead, investing in the RP brings better access to Canon’s evolving RF lens lineup and professional-grade glass, enhancing image quality and creative options.

Battery Life and Storage

• The M5 offers about 295 shots per charge, which is decent but will require spares on longer shoots.

• The RP manages slightly fewer shots at 250 per charge, reflecting higher sensor power draw and processing.

Both use SD/SDHC/SDXC cards, but the RP supports faster UHS-II cards, improving buffer clearing and video write speeds - a plus for heavy shooters.

Environmental Resistance & Durability

Worth noting, the RP includes splash and dust resistance, which the M5 lacks entirely. For outdoor photographers who face variable weather, this protection is a significant advantage.

High-Level Performance Ratings & Genre Suitability

To sum up performance with a clear overview:

According to DxOMark and in-house testing, the RP scores higher overall (85 vs 77). This is mainly driven by sensor performance and low light capability.

Breaking it down by photographic genre:

• Portraits - The RP leads with superior image quality and AF refinement.
• Landscape - The RP again with full-frame advantages in resolution and dynamic range.
• Wildlife & Sports - M5's faster burst rate is helpful, but RP’s AF system pulls ahead on tracking.
• Street & Travel - The M5’s compact size offers portability; RP’s superior image quality is a tradeoff.
• Macro - Both similar, though RP can benefit from better lenses and image quality.
• Night/Astro - RP’s high ISO prowess is crucial here.
• Video - RP with 4K and audio monitoring gear wins.

Real-world Sample Images Comparison

Take a close look below at side-by-side JPEG samples - portraits show richer skin tones from the RP, while the M5's images feel a tad more contrasty but less nuanced. Night scenes are smoother on the RP, with better shadow detail preservation.
