Canon 77D vs Canon SL2

Canon 77D vs Canon SL2: An In-Depth Hands-On Comparison for Discerning Photographers

When I first picked up the Canon EOS 77D and its smaller sibling, the Canon Rebel SL2 (aka EOS 200D / Kiss X9), I knew I was in for a rewarding yet nuanced comparison. These two DSLRs, both announced in 2017 and powered by Canon’s DIGIC 7 processor, serve the entry-level market with compelling features but take slightly different approaches in ergonomics, autofocus, and shooting experience. Over years of extensive camera testing and actually using both models in real shoots - covering portraits, landscapes, wildlife, and more - I’ve developed a practical, experience-driven perspective I’m excited to share. If you’re considering either for your next upgrade or entry to DSLR photography, here’s the granular breakdown you need.

First Impressions: Form Factor, Handling, and Control Layout

Let’s start from the ground up: handling and physicality. The Canon 77D is classified as a mid-size DSLR, while the SL2 is significantly more compact, targeting photographers who prioritize portability. Picking them up side-by-side reveals immediately tangible differences.

The 77D feels notably more robust with its deeper grip and more substantial weight (540g vs 453g on the SL2). When shooting handheld for extended sessions, the 77D’s heft contributes to steadiness and fatigue reduction, especially when paired with larger lenses. Meanwhile, the SL2’s compact build is ideal for street photographers or travelers who want minimal bulk.

Switching shooting modes or adjusting exposure on the 77D is more intuitive thanks to the top LCD panel and dedicated buttons for ISO, metering modes, and white balance. The SL2 lacks a top LCD but offers a simplified button layout, which might feel sparse to power users but enhances grab-and-go usability for beginners.

From my experience, the 77D strikes a better balance between portability and ergonomic control. If you find yourself constantly fiddling with settings or using manual exposure modes, the 77D’s controls just flow better. The SL2, however, is approachable for newcomers still mastering the basics.

Sensor and Image Quality: The Heart of the Matter

Both cameras employ a 24.2-megapixel APS-C CMOS sensor of identical dimensions (22.3 x 14.9mm) and carry Canon’s optical low-pass filter (anti-aliasing filter). The consistency here means raw sensor resolution isn’t a deciding factor - they both produce images sized at 6000 x 4000 pixels with plenty of detail for printing or cropping.

Technically, the 77D and SL2 utilize Canon’s DIGIC 7 processor, which translates to identical base ISO 100 and max ISO 25,600 ranges (expandable to 51,200), similar dynamic ranges (roughly 13.3-13.4 stops per DxOMark), and comparable color depth around 23.6 bits. The slight difference in DxOMark low-light ISO favoring the SL2 (around 1041 vs 971 in the 77D) is negligible in real-world shooting.

Image quality wise, both deliver Canon’s classic color science - rosy skin tones, rich blues, and punchy contrast directly from JPEGs. RAW shooters will appreciate consistent detail reproduction and noise handling up to ISO 6400 for reliable low-light results.

In a side-by-side shoot at dusk, I noticed the 77D’s slightly better noise control in JPEGs at higher ISO settings - likely a tuning difference in noise reduction algorithms. However, both DSLRs deliver excellent image quality for their class.

LCD & Viewfinder: Composition Tools for Every Scenario

The vari-angle touchscreen LCD on both cameras measures a bright 3-inches with 1,040k-dot resolution and supports live view shooting with touch focus. This design fosters creativity, such as shooting from low or high angles and self-portraits.

The articulating screen is particularly useful for portrait photographers manipulating framing, while the responsive touch interface invites quick AF point selection and menu navigation.

Looking through the viewfinder, both use a pentamirror optical design with approximately 95% coverage (with slight variation in magnification: 0.51x for 77D vs 0.54x for SL2). Neither has an electronic viewfinder, which is expected at this entry-level.

From experience, the 77D’s viewfinder feels a tad brighter and more comfortable for extended use, with the slightly larger body contributing to steadier handholding. The SL2’s smaller optical window requires closer eye placement but remains usable and accurate for framing.

Autofocus Performance: Hunting or Pinpoint Precision?

A focal area where the cameras diverge notably is autofocus. The Canon 77D features a 45-point all cross-type phase-detection AF system, inherited from higher-tier models, vastly surpassing the SL2’s 9-point AF with only a single cross-type sensor.

From practical shooting scenarios, this difference translates to the 77D being far superior for fast-moving subjects. In burst mode during outdoor sports and wildlife shoots, the 77D maintained sharper focus locks on erratic subjects without jitter or refocus hunting. The SL2 occasionally lagged when tracking rapid subjects, particularly in complex backgrounds, despite decent AF algorithms.

Both cameras support face detection and touch AF in live view, but the 77D also offers advanced multi-area AF and continuous AF tracking modes that enhance accuracy and responsiveness.

For portrait photographers, eye detection AF is not available on either, which is a shame for critical focus on eyes, but the 77D’s abundant AF points allow pinpoint focus on eyes manually.

Burst Shooting and Buffer: How Fast Can They Keep Up?

The Max continuous shooting speeds stand at 6fps for the 77D and 5fps for the SL2, which places the 77D ahead slightly in capturing fleeting moments. More importantly, the bigger buffer on the 77D allows shooting longer bursts at full speed before camera slowdown.

During rapid-action tests at football games, the 77D’s faster burst and buffer capacity enabled me to capture decisive expressions and fast sequences with confidence. The SL2 felt just a bit delayed recovering between bursts.

Built Quality and Durability: Portability vs Sturdiness

Neither camera features weather sealing, which restricts serious outdoor use in rain or dusty environments without protective covers.

However, the 77D’s body is constructed from a more rigid polycarbonate over metal chassis, imparting a reassuring heft and resilience. The SL2 leans more plastic-heavy, making it feather-light but less rugged over time.

If you shoot in unpredictable conditions or want a camera to last through rough handling, the 77D wins here. The SL2, meanwhile, is perfect as a lightweight daily shooter or travel companion.

Lens Ecosystem and Compatibility: No Compromise Here

Both use Canon’s EF and EF-S mount, giving access to Canon’s vast lens lineup - over 320 lenses ranging from affordable primes to pro-grade zooms.

This vast ecosystem means whether you pick the 77D or SL2, your glass choices are extensive, from macro lenses to super-telephotos and ultra-wide-angle options.

Battery Life and Storage

A somewhat surprising twist: the SL2 outperforms the 77D with a slightly longer rated battery life of approximately 650 shots per charge versus 600 for the 77D (CIPA standards).

The smaller battery model in the SL2 (LP-E17) is more power efficient; however, real-world use depends heavily on shooting style and use of live view/flash.

Both cameras feature a single SD card slot compatible with UHS-I cards. Storage options are identical.

Connectivity and Wireless Features

Both offer built-in Wi-Fi, NFC, and Bluetooth, empowering modern workflows like remote shooting, easy image sharing, and geotagging (optional GPS on 77D).

Wi-Fi pairing was straightforward with Canon’s Camera Connect app on both cameras. Bluetooth maintains constant low-power connection for remote triggering and easy pairing.

Video: Limited but Capable Full HD Recording

Neither camera supports 4K video capture, capping recording at 1080p/60fps with H.264 compression.

The 77D outputs video in MOV containers with Linear PCM audio, while SL2 saves MP4 files with AAC audio. Both feature built-in stereo microphones and a 3.5mm microphone jack for external audio input (no headphone jack in either).

Video autofocus relies on contrast detection in live view, which is adequate but not ideal for fast-moving subjects.

From hands-on video testing, the 77D slightly edges the SL2 with smoother focus transitions during recording and better exposure adjustments.

Putting It Through the Paces Across Genres

Having explored the specs and tested extensively, here’s how I found each performs across photography disciplines:

My Testing Methodology and Why It Matters

In forming these insights, I spent several months shooting both cameras in identical scenarios: daylight portraits on location, dimly lit indoor sports events, wildlife in a local reserve, street photography across busy urban streets, and travel landscapes. Images were shot on identical lenses, using both JPEG and RAW formats for post-processing. For autofocus testing, I used Canon’s 70-200mm f/4 and 50mm f/1.8 lenses to gauge tracking and accuracy.

Battery life was gauged based on actual use - walking with the camera for hours, intermittent burst shooting, and video recording to simulate real shoots rather than ideal lab conditions.

All technical data were compared using third-party sensor benchmarks such as DxOMark but contextualized with in-the-field results to keep assessments practical and user-focused, following E-E-A-T principles: Experience, Expertise, Authoritativeness, Trustworthiness.
