Canon Sl2 Vs Sl3 Comparison
Design and Build
When comparing the Canon SL2 vs SL3, their compact designs stand out immediately. Both measure 122.4 x 92.6 x 69.8 mm, making them some of the smallest DSLRs around—perfect for travel or casual shoots. The SL2 weighs 453g, while the SL3 is slightly lighter at 449g. That small difference can matter when you’re carrying gear all day.
Both cameras feel sturdy with comfortable grips and well-placed buttons. The SL3, however, has subtle improvements, like a more tactile mode dial and a better-positioned ISO button. These tweaks make it feel a bit more polished. I’ve shot with both in busy environments, and the SL3’s design feels just a tad more intuitive.
The vari-angle touchscreen on both is a standout feature. It’s great for vlogging or shooting from odd angles. The SL3’s screen is slightly more responsive, which I noticed when quickly adjusting settings during a shoot. Overall, both are portable and well-built, but the SL3 edges out slightly in refinement.

Image Quality
Both the SL2 and SL3 deliver impressive image quality for their class. The SL2 has a 24.2MP APS-C CMOS sensor, while the SL3 has a 24.1MP version—virtually identical in resolution. They both use Canon’s Dual Pixel CMOS AF, which shines for live view and video focusing. I’ve captured vibrant landscapes and portraits with both, and they rarely disappoint.
The key difference is the image processor. The SL2 uses the DIGIC 7, while the SL3 has the newer DIGIC 8. This upgrade gives the SL3 better noise reduction, especially at high ISOs, and slightly faster processing. During a low-light shoot, I found the SL3’s images a bit cleaner, though the SL2 still held its own.
Color accuracy is excellent on both, with Canon’s signature vibrant tones. The SL3’s processor might give it a slight edge in dynamic range, but both produce stunning photos for beginners and enthusiasts alike. For most users, the difference is subtle unless you’re zooming in closely.
Autofocus Performance
Autofocus is crucial, especially when capturing fast-moving subjects or precise portraits. Both the SL2 and SL3 have a 9-point autofocus system when using the viewfinder, which is decent for beginners but might feel limiting for advanced users. In live view, both benefit from Dual Pixel CMOS AF, which is excellent for video and stills. The SL3, however, takes it a step further with Eye Detection AF.
Eye Detection AF on the SL3 automatically focuses on the eyes in your frame, which is particularly useful for portrait photography. I’ve found this feature saves time and ensures sharper images, especially when shooting people or animals. The SL2 lacks this, so you’ll need to manually select the focus point, which can slow you down.
In low-light conditions, the SL3’s DIGIC 8 processor makes focusing faster and more accurate. I noticed this when shooting a fast-moving subject at dusk—the SL3 locked on more reliably. While the SL2 performs well, the SL3’s autofocus is noticeably more advanced, especially for dynamic scenes.
Continuous Shooting and Buffer
Continuous shooting is another area where the Canon SL2 vs SL3 differs slightly. Both offer 5 frames per second (fps), which is adequate for casual action photography. However, the SL3 has a larger buffer, allowing it to capture 15 RAW shots in a burst compared to the SL2’s 5. This was handy when I was photographing a sports event and needed to capture a sequence of actions.
The SL3 also starts up faster and has less shutter lag, which can be critical for candid moments. During a street photography session, I found the SL3’s responsiveness gave me an edge in capturing fleeting expressions. The SL2 is no slouch, but the SL3 feels more capable for fast-paced shooting.
Video Capabilities
If video is your focus, the SL3 is the clear winner. The SL2 shoots Full HD at 60 fps, which is fine for casual videos. The SL3, however, offers 4K at 24 fps, a major upgrade for vloggers or filmmakers. I shot a short travel video with the SL3, and the 4K footage looked sharp and detailed.
However, the SL3’s 4K mode has some limitations. It has a crop factor, narrowing the field of view compared to 1080p. Also, Dual Pixel AF isn’t available in 4K, so autofocus might not be as smooth. Despite these drawbacks, 4K is a significant step up for users planning to share videos online or on larger screens.
The SL3 also has Movie Digital IS, which reduces camera shake for smoother handheld videos. This was a lifesaver when I was filming while walking. The SL2 lacks this feature, so you’ll need a stabilized lens or gimbal for steady footage. For video enthusiasts, the SL3’s capabilities make it the better choice.
Battery Life
Battery life is a big differentiator. Both cameras use the LP-E17 battery, but the SL3 is far more efficient. The SL2 gets about 650 shots per charge, while the SL3 can hit 1070 shots, per CIPA standards. That’s a huge advantage for long shoots or travel.
I once shot a full day at a festival with the SL3 and didn’t need to swap batteries, which wasn’t always the case with the SL2. If you’re someone who forgets to pack spares, the SL3’s longevity is a major plus. Both are decent, but the SL3 clearly wins here.
User Interface and Features
Both cameras are beginner-friendly, but the SL3’s interface is a step up. Its menu system is better organized, with quicker access to key settings. The touchscreen is more responsive, making adjustments a breeze. I found myself navigating the SL3’s menus faster during a hectic shoot.
The SL3 also has a Feature Assistant, which explains settings and modes in real-time. This is perfect for newcomers or when you’re trying something new, like long-exposure photography. I showed it to a friend learning photography, and they loved how it simplified things.
Connectivity is another area where the SL3 shines. Its improved Wi-Fi and Bluetooth make transferring images to your phone or remote shooting via the Canon Camera Connect app seamless. The SL2 has these features too, but the SL3’s implementation feels smoother.
Accessories and Lenses
When choosing between the SL2 and SL3, consider the lenses and accessories you might want to use. Both cameras accept Canon EF and EF-S lenses, offering a vast selection from budget-friendly options to high-end professional glass. For beginners, the kit lens (usually 18-55mm) is a good starting point, providing a versatile focal range for everyday shooting.
Some popular lenses for these cameras include:
- Canon EF-S 55-250mm f/4-5.6 IS II: A great telephoto zoom for portraits and wildlife.
- Canon EF-S 10-18mm f/4.5-5.6 IS STM: Ideal for landscapes and architecture, offering a wide-angle perspective.
- Canon EF 50mm f/1.8 STM: A classic prime lens that’s excellent for portraits and low-light shooting.
Both cameras support Canon’s Speedlite flashes, which can open up new creative possibilities, especially for indoor or low-light photography. Since both have hot shoes, you can attach external microphones for better audio in your videos, which is particularly useful for vloggers. Consider getting a good camera bag, extra batteries (especially for the SL2), and a remote shutter release for long exposures or self-portraits.
Real-World Scenarios
Let me share a quick story. Last summer, I was on a trip to the mountains, and I brought the SL3 with me. The compact size was perfect for hiking, and the long battery life meant I didn’t have to carry extra batteries. I captured stunning landscapes and even some wildlife, thanks to the improved autofocus and Eye Detection AF.
On the other hand, when I’m teaching photography workshops, I often use the SL2 because it’s more affordable, and students can get a feel for a DSLR without breaking the bank. It’s reliable for stills and casual use, making it a great learning tool. Both cameras have their place, depending on the context.
For portrait photography, the SL3’s Eye Detection AF is a game-changer. I used it at a family event, and it consistently nailed focus on the subjects’ eyes, even in busy scenes. The SL2 requires more manual adjustment, which can be fine for static subjects but less ideal for dynamic settings.
In low-light scenarios, like indoor events or evening street photography, the SL3’s DIGIC 8 processor gives it a slight edge in noise reduction. I’ve shot with both at high ISOs, and while the SL2 performs well, the SL3’s images are noticeably cleaner. If you often shoot in challenging lighting, the SL3 might be worth the investment.
