Choose the Canon EOS Rebel T3i (EOS 600D) if you want an articulated screen for framing from above or below eye level, or you value its documented video controls. Choose the Rebel T2i (EOS 550D) if you do not need those features and find a better-condition body or more attractive used kit. Both are 18-megapixel APS-C DSLRs that support Canon EF and EF-S lenses, so the condition and contents of a particular used listing may matter more than the generation difference.
What is the main difference between the Rebel T3i and T2i?
The T3i’s rear LCD articulates; the T2i’s screen is fixed. That makes the T3i more convenient when you cannot comfortably put your eye to the viewfinder—for example, when photographing a child from near ground level or holding the camera above a crowd. It also helps when you need to see yourself while framing a shot.

Canon lists the T3i’s monitor as a 3-inch, approximately 1.04-million-dot articulated display in its EOS 600D specifications. The T2i’s fixed-screen design is documented in Canon’s EOS 550D instruction manual. The screen changes how flexibly you can compose using the rear display; it does not change the optical-viewfinder shooting experience.

| Decision point | Rebel T3i (EOS 600D) | Rebel T2i (EOS 550D) | What it means |
|---|---|---|---|
| Sensor resolution and class | 18-megapixel APS-C CMOS | 18-megapixel APS-C CMOS | They have the same headline resolution. That alone does not establish that their images are identical or that one has better image quality. |
| Rear display | 3-inch articulated LCD, approximately 1.04 million dots | Fixed rear LCD | The T3i offers more flexible framing from awkward angles. |
| Lens compatibility | Canon EF mount; EF-S lenses supported | Canon EF mount; EF-S lenses supported | Existing compatible EF or EF-S lenses can be used with either body. |
| Storage | SD, SDHC and SDXC card families | SD, SDHC and SDXC card families | Check the manual for card details and inspect any card included with a used kit. |
| Video | Full HD-era recording; video snapshots and an external stereo microphone input are documented | Full HD-era recording | Neither should be treated as a modern video-focused hybrid camera. Consult the relevant manual if a specific recording control matters. |
Canon’s T3i specifications and the T2i manual support the shared resolution, lens-platform and card-family comparison. These specifications do not establish a head-to-head image-quality winner.
#1 Best Overall
- Released on February 6, 2011
- 18MP APS-C CMOS sensor, 9-point AF system
- 3.7 frames per second continuous shooting
- ISO 100-6400 expandable to 12800
- 1080p HD video recording with manual controls
Which camera makes more sense for video?
The T3i has documented controls and features including manual recording-level adjustment, wind filtering, video snapshots and a stereo microphone input. Those may be useful if you want more control over recorded sound or short clips. The T2i is also a Full HD-era camera, but compare the manuals for the exact control you need rather than assuming the models offer the same video options.
These are older DSLR designs, not modern video bodies. Do not buy either expecting 4K recording, contemporary autofocus behavior or modern wireless connectivity. Canon’s T3i specification page and T2i manual are the references for their documented capabilities.

How should you choose between them used?
Canon’s discontinued-products index includes both the EOS 550D and EOS 600D. That makes used listings the practical buying context, though the index does not establish current stock or market prices. Compare the actual body and kit rather than assuming the newer T3i is always worth a premium.
- Inspect the body. Look for physical damage, worn controls, a loose or damaged screen hinge on the T3i, and signs that the camera has not been cared for.
- Check operation. Ask whether the seller has tested the buttons, dials, screen, viewfinder, card slot, autofocus and video recording. Do not treat a listing as tested unless it says so.
- Review shutter count if available. A count can help inform your decision, but it is only one part of the camera’s condition.
- Confirm what is included. Check for a battery and charger, and identify any bundled lens. The compatible lens platform is shared, but included accessories vary by seller.
- Read the return terms. A return policy gives you a route to address faults that were not clear from the listing.
- Compare the complete deal. If the articulated screen or T3i video controls matter to you, weigh them against the price and condition of that specific kit. Otherwise, a better-kept T2i may be the more sensible choice.
Canon’s discontinued products index identifies both camera models as discontinued. It does not provide a current used-market price or guarantee availability.

Verdict: T3i or T2i?
Pick the T3i when its movable screen will change how you shoot, or when its documented video controls suit your needs. Pick the T2i when those advantages are not important and the individual body or bundled kit is in better condition or better value. For either camera, prioritize a fully working, well-described used listing over the model name alone.
