The Canon EOS Rebel SL2 and SL3 are two of Canon’s smallest, lightest entry-level DSLRs, and the SL3 is the newer model with some video and feature upgrades. If you want the most current of the pair, choose the SL3; if you find a well-kept SL2 and mostly shoot stills, it can still do the job.
What These Cameras Are For
Both bodies are aimed at beginners who want a real DSLR experience in a compact shape. They use Canon’s EF-S lens mount, which also accepts EF lenses, so a large range of new and used lenses is available. Both have an articulating touchscreen, which makes self-portraits, low-angle shots and video framing easier than with a fixed screen.
Key Differences
| Area | Canon SL2 | Canon SL3 |
|---|---|---|
| Generation | Earlier | Newer |
| Video | Full HD class | Adds 4K with limits |
| Body class | Compact entry DSLR | Compact entry DSLR |
| Lens mount | EF-S | EF-S |
The SL3 is generally described as adding 4K video, though with restrictions that Canon documents, along with refinements to autofocus behavior and menus. Battery life, burst speed and exact sensor details should be confirmed on Canon’s pages rather than assumed from memory.
Who Should Choose Which
- Choose the SL3 if you want the more current body, plan to record video, or want the longer support period that usually comes with a newer model.
- Choose the SL2 if you mostly shoot photos and find one in good condition, since the stills experience is similar for everyday use.
Getting Better Results From Either Body
- Shoot in aperture priority with the aperture near f/4 to f/5.6 for walk-around photos as a general guide.
- Keep the shutter speed at 1/125 or faster for handheld shots of people.
- Use auto ISO with a ceiling of about 3200 in dim light, then adjust to taste.
- Learn the viewfinder autofocus first, then try live view for tripod shots.
- Upgrade lenses before bodies; a fast prime changes results more than a new camera.
Lenses to Pair With Either Body
Because both cameras use the EF-S mount, a good first lens purchase is a fast standard prime with an aperture around f/1.8 or f/2, which gives sharper pictures and more background blur than a typical kit zoom. Later, a telephoto zoom covers sports and wildlife, and a wide-angle zoom suits landscapes and interiors. Canon makes many of these lenses, and several third-party makers offer them as well, so check mount compatibility on each product page before you buy.
FAQ
Are the SL2 and SL3 mirrorless?
No. They are DSLRs with an optical viewfinder and a mirror, though both also offer live view on the rear screen.
Do old EF lenses fit?
Yes. The mount accepts both EF-S and EF lenses, but check each lens for any special requirements.
The Short Version
The SL3 is the newer, better-for-video option, and the SL2 is a capable stills camera if you find a good one. Choose by whether video matters to you, and confirm exact specifications on Canon’s site.
