Canon EOS Rebel T8i (850D) vs T7i (800D) (2020): Comparing Entry-Level DSLR Cameras

Amid speculations that Canon is abandoning all DSLR development comes leaks of a brand new entry-level model, the EOS Rebel T8i. It will be released as the Canon EOS 850D in EU, and it aims to replace the brand’s current top beginner-friendly DSLR camera, the Canon EOS 800D or Rebel T7i. Take a look below to see how these two cameras compare against each other.

The Canon EOS Rebel T8i and T7i look virtually identical.

Canon EOS 850D vs 800D Design
You’d be hard-pressed to spot the differences between the Canon EOS 850D (left) and the EOS 800D (right).

No real surprises here, as Canon keeps its signature look consistent throughout its cameras. It also makes sense that the Canon EOS Rebel T8i/850D follows closely after the model it’s meant to replace. The 850D is taller by a hair than the EOS Rebel T7i/800D but there’s a bit more noticeable drop in weight, at 515 grams vs 532 grams.

A quick look at the back shows that there are fewer buttons on the EOS Rebel T8i than on the T7i, resulting in a somewhat less cluttered interface. The button layouts are nearly the same, and mirrors the rest of Canon’s DSLR and mirrorless lines so users can feel familiar within the brand’s products.

Both cameras will have the same 3-inch LCD screen that can swivel out and rotate. Resolution also doesn’t see any changes, as these will display 1.04 million dots in full color. It’s unconfirmed yet whether the new EOS 850D will retain the 3.5mm headphone jack which was a welcome inclusion in the EOS 800D, as it improved audio during recordings.


The Canon EOS Rebel T8i will use a more advanced image processor than the EOS Rebel T7i.

Canon EOS 850D vs 800D Features
A couple more leaked photos of the Canon EOS 850D / Rebel T8i.

The leaked specs list shows that the Canon EOS 850D/T8i will have a slight decrease in megapixel count compared to the EOS 800D/T7i, at 24.1 MP vs 24.2 MP. It should still be the same APS-C sensor though. The EOS Rebel T8i keeps the 45-point cross-type AF system as well as Dual Pixel CMOS AF features of the EOS Rebel T7i, which sounds a tad unexciting given the latter was released roughly 3 years ago.

The big change is in the upgraded image processor of the T8i, as it will be powered by Canon’s DIGIC 8. This is the same processor used in 2019 releases such as the EOS 90D and EOS M6 Mark II. We can expect a noticeable improvement in overall speed to the camera’s operation compared to the DIGIC 7 on the T7i. No other new features are being reported yet so we’ll have to see what Canon officially reveals later in February.

The Canon EOS 850D (Rebel T8i) can record better quality videos than the EOS 800D (Rebel T7i).

Canon EOS 850D vs 800D Performance
Combining 4K resolution with Canon’s Dual Pixel CMOS AF should result in some pretty impressive videos.

Finally Canon’s entry-level DSLR offering joins the majority of other brands in being capable of 4K video quality topping out at 30 frames per second. Even better, the EOS Rebel T8i (850D) won’t have any cropping aside from the standard 1.6x crop of APS-C camera bodies from Canon. This is a nice upgrade to the 1080p at 60fps limit of the EOS Rebel T7i (800D).

Canon also further improves the EOS 850D’s burst shooting prowess, as it will have a 7.0 fps continuous shooting speed compared to the 6.0 fps of the EOS 800D. This will be slightly higher in Live View, at 7.5 fps. We’re excited to see how all of these upgrades will improve image and video quality in this new generation of beginner-level DSLR cameras.


The Canon EOS Rebel T8i is sizing up to be a better entry-level DSLR camera than the EOS Rebel T7i.

Though there’s really not much to form solid opinions on just yet, what’s been revealed so far about the Canon EOS Rebel T8i (EOS 850D) is very promising. For one, being able to record in 4K resolution will make it highly attractive to video content creators, especially if it retains the mic input, which should be safe to assume. With a more advanced DIGIC 8 image processor, it will come equipped with the latest performance boosts from Canon, along with its polished user-friendly interface.

If you can’t wait, the Canon EOS 800D (EOS Rebel T7i) is easily one of the best beginner-targeted DSLR cameras you can get. Canon provides helpful and easy to understand guides within the camera to help novices with its numerous settings. In addition to having one of the smoothest touchscreen interfaces in DSLRs, the EOS Rebel T7i is capable of stunning images with plenty of detail.
