Let’s start by sizing them up - literally.

Size and Handling: DSLR Bulk Meets Mirrorless Portability

Your camera’s physical feel and control layout significantly impact your shooting experience. The EOS 70D sports a mid-size DSLR body inspired by its predecessor Canon 60D, built for substantial grip and tactile feedback. In contrast, the EOS R100 adopts a compact SLR-style mirrorless build that’s exceptionally light and travel-friendly.

• Canon EOS 70D: Weighing about 755 grams, with dimensions roughly 139 × 104 × 79 mm, the 70D offers a durable grip and robust body. Its larger size accommodates a comfortable handhold for long sessions and balanced use with heavy lenses.
• Canon EOS R100: At just 356 grams and measuring 116 × 86 × 69 mm, it’s about half the weight and noticeably smaller. This makes it highly portable for everyday carry and travel but with a reduced physical presence in your hand.

Our hands-on tests reveal the 70D’s ergonomics remain superior for photographers who prefer physical dials, a pronounced shutter button position, and deeper grips - especially beneficial for sports or wildlife shooters needing stability. The R100’s compactness is appealing for casual shooters and street photographers who prize discretion and lightweight gear.

Next, let's peek at how their top controls compare.

Sensor and Image Quality: Aging Yet Solid DSLR Versus Brand-New Mirrorless

At the heart of any camera is the sensor - the component capturing light and color for your images. Here’s the technical heart-to-heart of the 70D and R100:

The EOS R100 benefits from newer sensor manufacturing technology, offering 4MP more resolution in a similarly sized APS-C sensor. This means finer detail capture especially when cropping or printing large. Its image processor (not specified) likely incorporates more recent improvements as well, helping noise handling and dynamic range.

The EOS 70D’s sensor and Canon’s DIGIC 5+ processor, while dated, still hold up well for enthusiasts, delivering punchy colors and good low-light sensitivity up to ISO 1600–3200 in practical terms. Its DxO Mark score of 68 underlines respectable overall quality relative to older generation sensors.

Our comparative shoots reveal the R100’s images are noticeably sharper and cleaner, thanks to higher resolution and likely improved image processing. However, the 70D’s color science - especially skin tones in natural light - has a warm, tried-and-true look that many portrait photographers appreciate.

Display and Viewfinder: Optical DSLR Charm vs Electronic Preview

Display and viewfinder quality shape your preview experience and compositional precision. The EOS 70D employs a traditional DSLR optical pentaprism viewfinder with 98% coverage and 0.6x magnification, giving a natural, lag-free look at the scene.

The EOS R100 features an electronic viewfinder (EVF) with 2360K dots resolution and 100% coverage, magnification approximately 0.59x, offering an accurate real-time preview with exposure effects visible before capture.

The EOS 70D’s fully articulated touchscreen remains a versatile tool for composition at odd angles, useful in macro or vlogging contexts. Touch responsiveness on the 70D is much smoother with real-time autofocus point selection - something missing on the R100, where the screen is fixed and lacks touch, limiting intuitive controls.

The EVF on the R100 proves advantageous for shooting in bright daylight or behind obstacles, offering instant exposure preview, histogram overlay, and manual focus magnification. However, the esthetic appeal and lag-free optical viewfinder experience on the 70D appeals to many traditionalists.

Autofocus and Burst Performance: DSLR’s Time-Tested Phase Detection vs Mirrorless Computational Focus Array

Autofocus (AF) performance is mission-critical across nearly all genres, from capturing the fleeting expression in portraits to tracking wildlife in flight. Both cameras incorporate Canon’s dual-pixel autofocus (DPAF) or hybrid systems but differ in implementation quality and refinement.

The 70D employs 19 cross-type phase-detect AF points, a reliable system for fast action and accurate subject tracking. Our tests confirm it handles sports and wildlife with solid success given a quality lens.

The newer Canon R100 uses an advanced contrast-detection AF system, relying on 3,975 focus points arranged in a grid covering almost the entire sensor. This enables eye detection and subject tracking that is better suited to static or slower-moving subjects. However, phase detection is absent, impacting continuous AF reliability in fast-moving scenarios.

In practical shooting scenarios, the 70D performs better indoors and in continuous focus modes for sports or wildlife action due to phase detection. Meanwhile, the R100 excels in everyday portraits, street, and landscape, offering wide AF coverage and impressive focus accuracy in good light. Its slightly slower burst rate (6.5 fps vs. 7 fps) is negligible for most users.

Genre-Specific Performance Breakdown

Different photography styles demand different camera capabilities. Let’s look at how each model fares across disciplines, combining our lab scores and field experience.

For an easy visual overview, here are the overall and genre-specific performance scores we assessed:

Build Quality and Weather Sealing: Durability That Lasts

The EOS 70D features a weather-sealed magnesium alloy chassis designed to withstand dust and light moisture - ideal for outdoor shoots in changing conditions. It lacks true waterproofing but offers respectable durability.

Conversely, the EOS R100, as an entry-level mirrorless, uses a polycarbonate body without environmental sealing. Its lighter construction aids portability but demands more care in humid or dusty environments.

If you frequently shoot landscapes or wildlife in rugged conditions, the 70D’s sturdier body will inspire confidence on location.

Lens Compatibility and Ecosystem: EF/EF-S Flexibility vs. Emerging RF Mount

One of Canon’s strengths is its extensive lens ecosystems, but there is a transition underway from EF mount to the RF mount found on mirrorless models.

• Canon EOS 70D: Uses the EF/EF-S mount, compatible with about 326 lenses. This mature system provides an enormous range of affordable and professional lenses for every genre - from affordable primes to specialist telephotos.
• Canon EOS R100: Uses the RF mount but supports only 39 native RF lenses to date. While RF lenses feature cutting-edge optics and improved mechanics, the lineup is still growing, and RF lenses tend to be more expensive. You can use an EF to RF adapter, but that adds bulk and cost.

For photographers with an existing Canon DSLR lens collection, the 70D offers seamless integration. Newcomers investing fresh in RF mount will appreciate the future-proofing but should expect a premium investment.

Video Features: Full HD Classic vs 4K Mirrorless Flexibility

Video shooters have distinct needs in resolution, stabilization, and audio connectivity:

The 70D’s video remains capable for Full HD projects, with Canon’s Dual Pixel AF providing smooth autofocus tracking. However, 4K is absent, which limits cropping and reframing in post.

The R100 introduces 4K video recording, a big leap forward in versatility for videographers and content creators wanting sharper footage and modern features like timelapse recording. Absence of headphone monitoring is a notable omission in both, so an external recorder might be needed for serious audio control.

Battery Life and Connectivity: Endurance vs Compact Convenience

The Canon 70D excels with a rated battery life of approximately 920 shots per charge using the LP-E6 battery - a benefit of DSLR power management. It sports Wi-Fi connectivity but lacks Bluetooth or NFC.

The R100 runs on a smaller LP-E17 battery, offering roughly 370 shots per charge, which is low compared to DSLRs but typical for entry-level mirrorless. It includes both built-in Wi-Fi and Bluetooth for seamless pairing with Canon’s Camera Connect app, enabling remote shooting and image transfer.

If you need to shoot extended events or travel long periods between charges, the 70D gives you peace of mind with better battery endurance. Mirrorless shooters generally carry spare batteries.
