First Impressions: Body Design & Handling

Canon 600D – The Classic DSLR Feel

The 600D, with its traditional SLR design and heftier 570g weight, feels substantial in hand - something seasoned DSLR shooters appreciate for stability. Its robust grip and decent-sized buttons give you plenty of tactile feedback, handy for learning manual controls without fumbling. The fully articulated 3” LCD is a practical marvel even today, letting you twist and angle the screen to weird poses for macro or vlog footage.

The optical pentamirror viewfinder, providing 95% frame coverage and 0.53x magnification, is typical for an entry-level DSLR. It delivers that crisp, zero-lag viewing experience that old-school photographers swear by. The 600D sports a slightly larger physical footprint (133x100x80 mm), which can feel bulky in travel scenarios but solid on a stabler tripod setup.

Canon R100 – Modern Compactness and Mirrorless Convenience

The R100 weighs a featherlight 356g, embracing the mirrorless revolution’s promise of portability. Its sleek, SLR-style mirrorless body (116x86x69 mm) fits snugly into smaller bags, ideal for street, travel, and casual use. The fixed, non-articulated 3” LCD lacks touchscreen capability, which feels like a missed opportunity in 2023, particularly on a camera targeting newcomers.

Where the R100 shines is its electronic viewfinder (EVF) - a 2,360-pixel resolution, 100% coverage, and 0.59x magnification - offering a bright, real-time preview of exposure, color changes, and focus peaking that the optical finder can't match. This EVF really bridges the learning gap for beginners, surfacing crucial shooting info on the fly.

Sensor Technology & Image Quality: Pixels and Performance

Understanding each camera’s sensor is fundamental, as this underpins everything else from resolution to low-light prowess.

Canon 600D’s Sensor: Vintage but Capable APS-C CMOS

The 600D sports an 18MP APS-C CMOS sensor with a standard low-pass filter to avoid moiré, preferred for its balanced resolution and manageable file sizes. The Digic 4 processor, a workhorse in its day, manages image processing and noise reduction, but by today’s standards, it’s a bit of a dinosaur.

DxOMark scores (which I trust for raw image quality analysis) give the 600D an overall score of 65, with respectable color depth (22.1 bits), dynamic range (~11.5 EVs), and low-light ISO performance (~793 ISO) for its era. It offers ISO 100–6400 natively, expandable to 12,800, but image noise becomes noticeable above ISO 1600.

Canon R100’s Sensor: Fresh 24MP APS-C Magic

The EOS R100 moves the needle with a 24MP APS-C sensor, stepping up resolution to 6000x4000 pixels and ISO sensitivity ranging up to 12,800 native (extendable to 25,600). Though the exact processor isn’t disclosed, the camera benefits from modern DIGIC algorithms, dual-pixel autofocus tech, and improved sensor design.

While DxOMark has yet to fully test this model, early real-world feedback and my hands-on experience show a more dynamic, cleaner output, especially in shadows, thanks to enhanced ISO handling and better noise reduction.

Some might wonder if the increased resolution sacrifices low-light performance - but the R100’s sensor efficiency and newer tech balance that trade-off well.

Side-by-side views of sensor size and resolution differences highlight Canon's generational progress.

Autofocus Systems: How Well Do They Nail the Focus?

Autofocus (AF) is the silent hero - nailing focus accurately and quickly boosts your keeper rate drastically.

The 600D’s AF: Modest Nine-Point Phase Detection

The 600D offers a nine-point phase detection AF system, with only one center cross-type sensor. It has basic face detection in live view, but no continuous autofocus tracking for moving subjects. For static scenes - portraits, landscapes - it still pulls through reliably, but fast action or wildlife shooting becomes a challenge.

In my testing, the camera hesitated or missed focus on erratic subjects or when subjects were off-center. The AF struggled especially under dim lighting, demanding manual fine-tuning.

The R100’s Autofocus: A Quantum Leap with 3,975 AF Points

The R100 shakes things up with a staggering 3,975 selectable AF points covering deep portions of the frame. Featuring advanced face detection, eye detection, and continuous autofocus tracking, it dramatically improves focus precision on moving subjects. Live view focus utilizes contrast detection, while phase detection is not part of the specs here - a curious choice for a mirrorless camera, but in practice, AF performance is competent.

During my wildlife shoots, the R100 nailed focus on erratically moving birds and squirrels far better than the 600D, especially in daylight. In continuous shooting mode (6.5 fps), AF kept pace admirably.

Ergonomics & User Interface: Who’s Easier to Use?

The 600D’s tactile buttons, dials, and fully articulated screen lend it an advantage for photographers who want full control plus flexibility in shooting angles. However, its user interface is somewhat dated - navigation menus can feel clunky to newcomers.

In contrast, the R100 sacrifices physical controls for simplicity: fewer buttons, no touchscreen, and a fixed rear screen. The menu system feels lean and beginner-friendly, but advanced users might find themselves wishing for direct access to certain settings.

The R100’s built-in Wi-Fi and Bluetooth offer seamless sharing and remote control via smartphone apps - modern conveniences the 600D simply cannot match.

Versatility Across Photography Genres

When evaluating cameras, I test them across multiple genres to see which fits best where.

Portrait Photography

Portrait work depends on skin tone accuracy, bokeh quality, and autofocus precision.

• The 600D’s 18MP sensor renders pleasant skin tones, though its single cross-type AF points mean you’ll often focus-recompose.
• The R100’s higher resolution captures finer detail in eyes and hair, with excellent eye-detection autofocus improving sharpness on faces.
• Bokeh quality largely depends on lens choice; the R100’s RF mount lenses (though fewer than EF lenses) tend to be optically excellent, delivering smooth background blur.

Landscape Photography

Here, resolution, dynamic range, and weather sealing matter.

• The 600D lacks weather sealing and is more cumbersome to carry on hikes.
• The R100 isn’t weather-sealed either, but its smaller footprint aids portability.
• The R100’s bigger pixel count and improved dynamic range better capture shadow details and bright skies.

Wildlife & Sports Photography

Speed and tracking AF are crucial.

• The 600D’s slow 4 fps burst and limited AF points render it less ideal for fast-moving subjects.
• The R100’s improved 6.5 fps and comprehensive AF coverage excel in locking onto moving animals and athletes.

Street Photography

Discretion and portability are key.

• The 600D’s bulk and mirror slap can be intrusive.
• The R100’s quiet shutter modes and small size enhance stealth.

Macro Photography

Precision focus and articulation.

• The 600D’s articulated screen gives compositional flexibility.
• The R100’s fixed screen is less versatile here.

Night / Astrophotography

ISO noise and exposure options dominate.

• The 600D was respectable in low light but noisy above ISO 1600.
• The R100’s better high-ISO resistance is a clear advantage for starry skies.

Video Capabilities

• 600D maxes at 1080p 30fps, with a microphone port but no headphone jack.
• R100 offers 4K UHD (3840x2160) at 24fps, also with a mic port. Impressive for entry-level!

Battery Life & Storage

Despite being older, the 600D offers 440 shots per charge using an LP-E8 battery, which is generous.

The R100 offers slightly fewer shots per charge (around 370), likely due to electronic viewfinder and video capabilities. Both use the common LP-E17 battery, a plus for RF mount users.

Each uses a single SD card slot (SDHC/SDXC), with UHS-I compatibility on the R100 for faster write speeds.

Lens Ecosystem & Mount Compatibility

A major factor influencing long-term usage:

• Canon’s EF and EF-S mount (600D) boasts 326 lenses, including vintage legends, affordable primes, and pro zooms with vast third-party support. This is a proven ecosystem with unparalleled versatility.
• Canon RF mount (R100) is growing, with only 39 native lenses as of mid-2024, though RF adapters enable EF/EF-S lens use at minimal penalty.

For newcomers wanting ready-made lens options and budget-friendly glass, the 600D ecosystem offers more choice immediately. But RF mount is the future with superior optical designs and better communication.

Connectivity and Modern Conveniences

• 600D has Eye-Fi compatibility (ancient wireless tech), HDMI, USB 2.0, and a mic port.
• R100 features built-in Wi-Fi, Bluetooth, mic and HDMI ports, reflecting modern wireless sharing expectations.

Environment and Durability

Neither camera is weather-sealed, splash-proof, or shockproof. For harsh outdoor work, both require care and weather protection accessories.

Price and Value Assessment

• The Canon 600D, typically found in used or clearance markets, goes for about $799 USD bundled (new back in 2011), but now is often found under $300 - an incredible value if you want a DSLR experience.
• The Canon R100 retails at approximately $479 USD brand new - giving you newer technology, lighter body, and 4K video for a lower price point.

Price-performance here is nuanced: The 600D offers DSLR tactile satisfaction and lens ecosystem but feels outdated; the R100 delivers modern features and better sensor tech but fewer lens choices.

My Hands-On Testing Highlights

For a weekend portrait shoot under golden hour, the Canon R100’s autofocus and eye-detection made focusing effortless. The 600D required manual finesse, slowing down my workflow but rewarding with pleasant skin tone rendition.

Hiking rugged trails for landscape shoots, the R100’s compact size was a relief, though I missed the 600D’s fully articulated screen when framing low-angle shots.

Fast-moving birds at dawn exposed the 600D’s AF limitations - many missed shots. The R100 tracked more accurately, turning the shoot from a trial to a joy.

Urban night photography was far better with the R100 due to its superior high-ISO handling and 4K video capabilities, providing creative options that the 600D simply can’t match.
