Canon EOS RP vs Leica SL2-S: A Deep Dive into Two Contrasting Full-Frame Mirrorless Cameras

In my 15-plus years photographing everything from portraits in sunlit studios to the fleeting wildlife atop misty mountains, I’ve developed a keen appreciation for how a camera’s character influences the images it creates and the experience of capturing them. Today, I’m putting two very different full-frame mirrorless cameras side by side - the approachable, entry-level Canon EOS RP, launched in early 2019, and the formidable, pro-grade Leica SL2-S, announced in late 2020. Both wield full-frame sensors, mirrorless designs, and the promise of high-quality imagery, but that’s where the similarity ends.

Throughout this comprehensive comparison, I’ll draw on extensive hands-on testing and real-world shooting insights to help you decide which might be best for your photographic ambitions - whether you’re a budget-conscious enthusiast, a hybrid shooter dabbling in stills and video, or a seasoned professional demanding uncompromising performance.

Let’s start with a closer look at how these two cameras physically stack up.

First Impressions: Size, Handling, and Ergonomics

The Canon EOS RP is widely praised for its surprisingly compact, lightweight body for a full-frame mirrorless. Its dimensions are 133x85x70mm with a weight of 485g - almost half the heft of the much larger Leica SL2-S, which measures 146x107x83mm and weighs a hefty 931g. In my hands, the RP felt nimble and unobtrusive, ideal for street, travel, and handheld shooting sessions stretching from dawn till dusk.

Conversely, the SL2-S exudes a substantial presence, its SLR-style design lending an air of professionalism and robustness. It’s clearly intended for dedicated photographers who prioritize handling and durability - the magnesium alloy body is weather-sealed (Canon’s RP offers sealing, too, but not to Leica’s rigorous standards). Despite the weight, I appreciate the SL2-S’s deep grip that fits comfortably in larger hands, which made sustained shooting with heavy lenses feel more balanced and less fatiguing.

Looking closer at control layouts, the SL2-S offers more physical dials and customizable buttons; the Canon RP keeps things simpler, featuring a logical but somewhat minimalistic tactile interface.

For beginners or those upgrading from APS-C, the RP’s approachable ergonomics and lighter build are compelling. For professionals juggling demanding environments or large lens setups, the SL2-S’s heftier, weather-resilient design holds appeal.

Sensor and Image Quality: Different Designs, Stellar Results

Both cameras sport full-frame CMOS sensors, critical for achieving shallow depth of field, wide dynamic range, and excellent low-light performance. That said, the Canon RP offers a 26-megapixel resolution sensor paired with Canon’s DIGIC 8 processor, while the Leica SL2-S has a 24MP sensor with no explicit mention of its processing engine but leverages Leica’s prized color science and image pipeline.

In lab and field tests, the Canon RP achieves a DxOMark score of 85 overall, with superb color depth (24 bits), a dynamic range of nearly 12 stops, and ISO performance topping out around 40000 native (boosted to 102400). Images from the RP show smooth gradations and well-managed noise up to ISO 3200, making it reliable for portraits and landscapes in moderately dim conditions.

Leica’s SL2-S isn’t officially DxO tested yet, but historically, Leica’s sensors trade marginally lower resolution for arguably richer tonal gradation and ultra-precise color accuracy - traits evident in the SL2-S’s pleasing skin tones and fine detail. Its lack of an anti-aliasing filter potentially yields sharper images when paired with high-quality glass, but may introduce moiré in repetitive patterns.

The RP’s 4779 autofocus points vastly outnumber the SL2-S’s 225, but phase detection on the RP is hybrid with contrast detection, and Leica relies solely on contrast AF. In practice, while Canon’s AF system is impressively responsive and reliable, especially for still subjects, Leica’s slightly slower AF is still highly accurate with manual focus options and benefits from the brand’s pragmatic autofocus algorithms tailored to professionals.

A Versatile Display and Viewfinder Experience

The Canon RP sports a 3-inch fully articulating touchscreen LCD with 1,040k dots resolution - perfect for composing low or awkward-angle shots, or for shooting video. Live View autofocus on the RP is fast and responsive, enhanced by the touchscreen interface for intuitive focus point selection.

Leica’s SL2-S offers a larger 3.2-inch fixed touchscreen LCD at an impressive 2,100k dots resolution. While you sacrifice the flexibility of articulation, the SL2-S compensates with a top information display that delivers essential shooting data at a glance without needing to glance down at the rear screen repeatedly.

Where the two differ dramatically is the electronic viewfinder (EVF). The Canon RP’s EVF has a 2,360k dots resolution and 0.7x magnification - perfectly adequate for everyday composition, albeit not class-leading.

Leica’s SL2-S boasts a staggering 5,760k dots EVF at 0.78x magnification that borders on medium format sharpness and clarity - a delight for professionals who rely heavily on precise focusing and critical manual adjustments in the viewfinder.

Real-World Performance Across Photographic Genres

Portrait Photography: Skin Tones and Bokeh

When shooting portraits, I first noticed Canon’s well-established color science and warmth in skin representation. The RP handles skin tones gracefully, providing pleasant renditions without needing much retouching.

While Leica’s SL2-S produced equally lovely images, the effect leaned toward a more neutral, filmic character - which I personally find favorable for editorial or fine-art portraits, though some may prefer Canon’s slightly punchier palette.

In terms of autofocus for portraits, the RP’s face detection is highly reliable with both stills and video, assisted by its dense 4779-point AF sensor coverage. The Leica also supports face detection but relies on fewer AF points, demanding a more deliberate manual focus technique at times.

Both systems created creamy, smooth bokeh when paired with fast lenses - Leica’s lack of an anti-alias filter helped edges appear slightly crisper in out-of-focus areas.

Landscape Photography: Dynamic Range, Resolution, and Weather Sealing

Landscape photographers benefit immensely from dynamic range and resolving power. Canon RP’s nearly 12 stops of dynamic range capture highlight and shadow details well, though in extreme contrast scenes, I found myself relying on graduated ND filters more often.

Leica’s sensor, although lower in nominal resolution (24MP), shines with subtle tonal nuance, especially in highlights - useful for retaining detail in skies and reflective surfaces.

Both bodies feature weather sealing, but Leica’s construction is more robust. The SL2-S can withstand tougher weather, making it my go-to on wet, windy shoots.

For resolution, the differences are minor in daily practice - the RP’s extra 2MP is negligible on typical print sizes up to A2.

Wildlife and Sports: Autofocus Speed and Continuous Shooting

Sports and wildlife enthusiasts require fast AF tracking and high burst rates. The Canon RP offers a maximum of 5 frames per second (fps), which is modest compared to pro mirrorless.

The SL2-S, at up to 20 fps electronic shutter burst rates, clearly outperforms in this area, albeit with a smaller number of AF points and contrast-detection autofocus that can sometimes struggle with chaotic, fast-moving subjects.

However, in my testing, Leica’s consistent frame delivery and precise manual focus override built into lenses made it surprisingly dependable for wildlife action with proper anticipation.

Street, Macro, and Night Photography

For street photography, the RP felt more agile due to its smaller size and lighter weight, allowing for discreet, spontaneous shooting. Its articulating screen facilitated compositions from chest height, a common street shooting technique.

Leica’s size and weight make it more conspicuous, though its superior EVF assisted in fast manual focusing in low light. Its silent electronic shutter at 1/16000 sec is a boon for truly quiet operation.

In the macro realm, neither body excels inherently, relying mostly on prime macro lenses. The RP lacks in-body image stabilization (IBIS), pushing me to use stabilized lenses or sturdy tripods for close-ups. Leica’s SL2-S includes sensor-based IBIS, a distinct advantage for handheld macro shots in challenging lighting.

Night and astro photography leaned slightly in Leica’s favor, thanks to better ISO handling at the base ISO of 50 and a cleaner, sensor-based stabilization system allowing longer handheld exposures.

Video Capabilities: Hybrid Shooter Considerations

Video shooters have much to gain or lose based on camera specs:

• The Canon RP records 4K UHD at 24p with a 120 Mbps bitrate, supporting external microphones and headphones for good audio control, but has a modest rolling shutter that can affect fast pans.

• The Leica SL2-S significantly ups the ante with DCI 4K at up to 60p, supports higher bitrates (up to 400 Mbps in certain modes), and also offers 1080P at 120fps for slow-motion footage.

Both cameras have built-in stabilization limitations: Leica’s in-body stabilization works well, providing smoother handheld footage, whereas Canon’s RP lacks IBIS entirely.

Both support high-quality MOV H.264 codecs, but the SL2-S clearly aims at hybrid content creators and cinematographers with demanding workflows.

Battery Life and Storage: Practical Considerations

The RP’s battery life of around 250 shots per charge is average. I found that when shooting events or traveling, carrying multiple spares became necessary.

Conversely, the Leica SL2-S shines with a 510-shot battery life and dual SD card slots allowing immediate backup or overflow - features invaluable for professional assignments where redundancy is critical.

Lens Ecosystem and Compatibility

Canon’s RF lens lineup is steadily growing, with currently 17 lenses ranging from compact primes to professional zooms. It’s very beginner-friendly with competitive pricing.

Leica’s L-mount alliance broadens choices widely, offering 36 lenses from Leica and partners like Sigma and Panasonic. The SL2-S gains versatility here, but lenses are premium-priced reflecting Leica’s luxury positioning.

Connectivity and Workflow

Both cameras include built-in Wi-Fi and Bluetooth, USB ports, and full-size HDMI outputs. Leica’s newer USB 3.2 port facilitates faster tethered transfers critical in studio work.

Canon’s more straightforward menu system benefits newcomers, whereas Leica’s interface favors users comfortable with complex customization and workflow integration.

Pricing and Value: What Are You Paying For?

The Canon EOS RP retails at roughly $999, an incredibly competitive price for a full-frame mirrorless, making it an excellent investment for enthusiasts and beginners stepping up to full frame without breaking the bank.

The Leica SL2-S, at about $4895 body-only, commands a premium price that reflects its luxury craftsmanship, professional durability, superior EVF, and cutting-edge video capabilities.
