Canon EOS Rebel SL3 vs Canon EOS Rebel T8i: Which DSLR Should You Choose?

Over my 15+ years testing cameras across genres - from studio portraits to wild landscapes - I've encountered a vast spectrum of gear. When it comes to entry-level DSLRs, Canon’s Rebel line has been a long-standing favorite among enthusiasts and beginners alike. Today, I’m putting the Canon EOS Rebel SL3 (also known as EOS 250D or EOS Kiss X10) head-to-head with its slightly newer sibling, the Canon EOS Rebel T8i (EOS 850D or EOS Kiss X10i). Both sit comfortably in the entry-level DSLR category but come with nuanced differences that could sway your buying decision depending on your photography style and needs.

I spent several weeks testing both cameras extensively across multiple photography disciplines and real-world shooting situations. Here's my comprehensive, experience-driven comparison to help you pick with confidence.

Design and Handling: Compact Comfort vs. Enhanced Control

Right out of the box, the SL3 impresses with a notably compact and lightweight body at just 449g, appealing to photographers who prize portability. Its smaller footprint makes it ideal for travel and street photography where discretion and ease are priorities. By contrast, the T8i is more robust and slightly heavier at 515g. Its dimensions are bigger in all directions, lending a more substantial grip that can provide better stability when shooting for extended periods, especially with larger lenses.

Handling these cameras side by side, the SL3 feels more nimble and less imposing, inviting spontaneous shooting. The T8i's body is chunkier, with a better-defined DSLR feel that some users will find more comfortable for professional work or wildlife photography sessions requiring long lens setups.

Both models sport Canon’s signature fully articulated 3.0-inch touchscreen LCD with 1,040k-dot resolution, ideal for live view shooting and vlogging. The vari-angle design affords flexibility when shooting from creative angles or selfies.

Examining the top plate, the T8i gains subtle advantages with a more sophisticated control layout. It offers a dedicated Mode Dial Lock, allowing you to avoid accidental mode shifts, alongside a quick-access AF-ON button that the SL3 lacks. This button is invaluable for back-button focusing, a technique favored by wildlife and sports photographers to improve autofocusing responsiveness.

The SL3’s controls lean toward beginner-friendly simplicity, with fewer buttons and a more streamlined interface, which can be less intimidating for newcomers but less efficient for power users.

Imaging Core: Same Sensor, Familiar Strengths

Both cameras share an identical 24.1MP APS-C CMOS sensor measuring 22.3mm x 14.9mm with a 1.6x crop factor. The sensor includes an antialiasing filter, contributing to clean images with a traditional Canon color science signature - warm skin tones and natural hues.

In my hands-on tests, I observed that image quality between the two models was nearly indistinguishable. Both captured detailed files up to 6000x4000 pixels, excellent for large prints, extensive cropping, or creative compositing.

ISO performance is similar as well, with a native range of 100-25,600 expandable up to 51,200. Although not the best in class for low-light shooting, both manage noise well up to ISO 3200-6400, which covers most typical shooting situations. Highlights are well-controlled, maintaining an appealing dynamic range for landscape and event photographers.

Viewfinder and Screen: Optical Tradition Meets Modern Display

Both cameras retain optical pentamirror viewfinders instead of pricier pentaprisms, offering 95% frame coverage and around 0.5x magnification. For photographers who prefer shooting through an optical viewfinder - especially in bright daylight - the experience is satisfactory but not immersive. Neither model has an electronic viewfinder (EVF), which is more common in mirrorless cameras today.

The fully articulating touchscreen on both makes for intuitive focus selection and setting adjustments, particularly in live view. Canon’s menu system remains broadly the same across both, known for beginner accessibility yet retaining enough depth for advanced customization when needed.

Autofocus and Performance: Subtle but Meaningful Advances

This is where the T8i distinguishes itself more clearly. While the SL3 uses a 9-point phase-detection autofocus (AF) system with just one cross-type sensor, the T8i upgrades to a 45-point AF system with multiple cross-type points (exact number Canon does not specify, but significantly more than SL3). This enhancement significantly increases focusing flexibility and accuracy, especially with moving subjects.

In practical shooting situations, such as wildlife or sports, I noted the T8i tracked subjects more reliably with fewer focus misses. The SL3’s limited AF points can make it tricky to lock focus on erratically moving targets or when composing off-center.

Autofocus options are comparable in other respects: both cameras support touch tracking, face detection, and continuous AF in live view mode, harnessing Canon’s Dual Pixel CMOS AF technology, widely regarded as one of the best in the DSLR realm.

When it comes to burst shooting, the T8i offers a faster continuous shooting speed of 7.5fps, ideal for capturing fleeting moments in action scenes. The SL3 provides a more modest 5fps, sufficient for casual sports or family events but limiting for serious action photography.

Battery Life and Connectivity: Practical Considerations

One area where the SL3 shines is battery endurance. Rated at approximately 1070 shots per charge (measured by Canon’s CIPA standards), it significantly outlasts the T8i’s 800 shots. If you are a traveler shooting long days without access to frequent charging, the SL3’s efficiency can be a boon.

Both DSLR bodies accept the same LP-E17 battery pack, but the SL3’s simpler processing and fewer AF points help conserve power.

For connectivity, both cameras feature built-in Wi-Fi and Bluetooth, making image transfer and remote shooting via the Canon Camera Connect app seamless. Neither offers NFC or GPS by default, though the T8i supports an optional GPS module.

Video: Capable but Not Cinema-Grade

Both cameras shoot 4K UHD (3840x2160) at 25p with a 120 Mbps bitrate in MPEG-4 H.264 format. The T8i, however, provides slightly more versatile frame rate options, including 23.98p and Full HD 1080p up to 60fps, appealing to vloggers and casual videographers.

Neither camera offers in-body image stabilization (IBIS), relying instead on lens-based stabilization where available. Both have a microphone input but lack a headphone jack, limiting real-time audio monitoring.

4K video on these cameras suffers from a significant crop factor beyond the typical 1.6x sensor crop, narrowing the field of view compared to 1080p modes. Slow-motion options are limited, so filmmakers will find these cameras best for documentary-style or casual video projects rather than professional cinema work.

Build Quality: Solid but Not Weather Sealed

Neither the SL3 nor the T8i offers environmental sealing, dustproofing, or weatherproofing. Both are constructed from sturdy polycarbonate reinforced with metal frames, resilient enough for daily use but requiring care in harsh conditions.

The T8i’s build feels more solid overall, with tighter tolerances and a more confident shutter release feel. The SL3’s compactness necessitates some ergonomic compromises but remains comfortable for moderately long shoots.

Lens Ecosystem: Endless Options

Both cameras share the Canon EF/EF-S lens mount, granting access to Canon’s vast range of over 300 native lenses - including some of the best DSLR optics ever made, plus third-party options from Sigma, Tamron, and others.

This shared lens compatibility means you can mix and match lenses without limitation, a huge advantage if you plan to upgrade to Canon’s higher-end bodies later.

Specialized Photography Use Cases: Which Camera Excels Where?

Let me break down how these cameras fare across key photographic disciplines, bringing in practical insights from my field tests.

Portrait Photography

Skin tones and bokeh quality: Both cameras deliver Canon’s characteristic warm, flattering skin tones. The slight difference in autofocus points on the T8i allows more precise focusing on eyes, especially with shallow depth-of-field lenses, improving portraits. Without eye-tracking AF, manual check remains essential, but in my tests, the T8i’s improved AF made face detection snappier.

Bokeh quality hinges primarily on the lens, so your choice of prime or zoom matters more than the camera body here.

Landscape Photography

Dynamic range and resolution are identical given the sensor. Both handle highlight recovery well and produce detailed images for large prints. The SL3’s lighter design makes carrying it on long hikes less tiresome.

Weather sealing is absent on both, a downside if you expect to shoot in rugged outdoor conditions without extra protection.

Wildlife Photography

This is arguably the area where autofocus and burst rate matter most.

The T8i’s 45-point AF system paired with 7.5fps shooting rate makes it more suited for tracking moving animals. The SL3’s limited 9-point AF grid and 5fps burst rate may result in missed shots during fast action.

If wildlife is your focus, the T8i offers tangible benefits in responsiveness and flexibility.

Sports Photography

Similar to wildlife, fast and accurate tracking is critical.

The T8i’s advantages persist here: more AF points, faster continuous shooting, and quick AF acquisition mean better chances of capturing crucial moments on the field.

The SL3 is competent for casual sports photography but struggles with fast-paced, unpredictable movement.

Street Photography

Here, the SL3 truly shines.

Its smaller size and lighter weight make it less conspicuous, encouraging candid shots. The articulating touchscreen helps with shooting from low angles or discreet positions.

The T8i is bulkier and more DSLR-like, which might attract more attention, though its superior AF could aid quick snapshots when timing matters.

Macro Photography

Both cameras lack built-in stabilization, so macro shooters benefit more from stabilized lenses and tripods.

Focusing precision in live view with Canon’s Dual Pixel AF is reliable on both, but the wider AF coverage on the T8i can aid composition.

Neither offers focus bracketing or stacking features, which are niche tools that advanced macro photographers might miss.

Night and Astro Photography

Low-light ISO performance is similar, as is shutter speed range (max 30s).

For astro, external intervalometers or custom apps may be necessary to exploit long exposures fully, both cameras support time-lapse recording.

The SL3’s superior battery life is helpful for extended night sessions.

Video Work

While neither is a cinema camera, the T8i’s richer frame rate options and better AF point coverage in video mode make it the stronger choice for video enthusiasts.

Microphone input supports external mics on both, but absence of headphone jack is a limitation.

No stabilized video means investing in gimbals or stabilized lenses for smooth footage.

Workflow and Professional Use

If you’re a professional or semi-pro passionate about integrating your entry-level body into a broader workflow:

• Both cameras support Canon’s CR3 RAW format offering improved compression without quality loss.
• USB 2.0 connectivity limits tethering speed, but Wi-Fi features facilitate file transfer.
• The SL3’s lower weight favors travel and event workflows, while the T8i’s more commanding presence is encouraging for studio or location sessions demanding robust controls.
