The Canon EOS 850D (known in the U.S. as Rebel T8i) is the continuation of the EOS 800D (Rebel T7i), which was launched in 2017. The attention of the camera world may have changed to mirrorless, but many People still prefer DSLRs, so is the 850D an update large enough for its predecessor?

The most obvious update is 4K video capture. But the 850D also brings a series of smaller and more subtle updates, including a new processor, which should improve your overall shooting experience.

These two cameras look almost identical, have the same pentamirror viewfinder magnification and familiar 3-inch variable-angle touch screens. So what else is different and is there enough to convince you to change your EOS 800D / Rebel T7i?

Sensor

  • Canon EOS 850D / Rebel T8i: 24.1MP double pixel APS-C CMOS sensor
  • Canon EOS 800D / Rebel T7i: 24.2MP double pixel APS-C CMOS sensor

Those who expect a great sensor update may be disappointed with the Canon EOS 850D / Rebel T8i. It has a 24.1MP APS-C sensor, compared to the old 24.2MP chip of the 800D. These are the megapixel counts & # 39; effective & # 39 ;, and the total sensor for each is 25.8 megapixels.

It gets the same area of ​​the sensor and the difference in resolution is minimal. We hope that the EOS 850D has the same chip as the Canon EOS 250D. And there is not a large image quality gap between the 800D and the 250D.

This apparent tread of water is not a bad thing. A resolution of 24MP is good for an APS-C sensor, as it offers a good balance of details at low ISO and reasonably large photosites for when higher sensitivities are needed.

No wonder the two cameras have the same ISO range. Both have a native ISO range of 100-25,600, which can be extended to 51,200 when you need to shoot in a very dark environment and can withstand your images just not looking so good.

The shutter speeds in the tap are also the same, at 1/4000 of a second up to 30 seconds, for when the light is very low and its tripod is very resistant.

Autofocus

  • Canon EOS 850D / Rebel T8i: 45 cross-type points, 143 live viewing points
  • Canon EOS 800D / Rebel T7i: 45 cross-type points, 49 Live View points

We are used to seeing what appear to be great improvements for AF systems in mirrorless cameras, because they are rooted in the sensor. But in the lower cost DSLR world? Not that much.

Like its predecessor, the Canon EOS 850D / Rebel T8i has 45 cross-type focus points. This may seem like a low number if you're more fan of mirrorless cameras, but focusing with them will be fast and accurate.

Canon states that the 850D is better in low light focus, with locking using the center focus point at -4EV, compared to -3EV in the 800D.

There is a clearer difference when switching to Live View, using the LCD screen to compose. In both cameras, this reverts from the traditional AF phase detection system to one based on the Dual Pixel AF of the sensor.

The Canon EOS 800D has a maximum of 49 focus points on the screen, with the 850D up to 143 points, depending on the shooting mode used. Of course, if you use Live View most of the time, it is probably worth looking at a mirrorless camera like the Canon EOS M6 Mark II instead of a DSLR.

Processor and performance

  • Canon EOS 850D / Rebel T8i: Digic 8 processor, burst shooting up to 7 fps
  • Canon EOS 800D / Rebel T7i: Digic 7 processor, burst shooting up to 6 fps

Shooting performance highlights one of the most obvious benefits of the Canon EOS 850D / Rebel T8i. It has a new Digic 8 processor, capable of burst speeds of up to 7 fps. Or 7.5 fps using Live View.

The 800D Digic 7 processor shoots at up to 6 fps. While this update does not raise the 850D to a new level of sport-style shooting, we will take whatever momentum we can get if that means capturing that perfect frame during quick action.

This new processor should also see some improvement in the handling of higher ISO noise. Judging by the Canon EOS 250D, a slight reduction in color noise is the most likely result in the real world.

The measurement sensor has also changed, from one with 7,560 points in the EOS 800D to 200,000 points in the EOS 850D. This should also help with auto focus performance.

Another core technology remains the same, with both cameras offering Wi-Fi, Bluetooth and NFC connectivity. They also use the same LP-E17 battery. But presumably, thanks to the improved efficiency in some of the new equipment, the EOS 850D is rated for up to 800 shots, compared to the 800 shots of the 800D (from the industry standard CIPA ratings, in viewfinder mode).

Video

  • Canon EOS 850D / Rebel T8i video: 4K / 25p, 1080 / 60p
  • Canon EOS 800D / Rebel T7i video: 1080 / 60p

The shooting speed gave us the first major improvement of Canon EOS 850D, but the video offers the most important. You can record videos with a resolution of 4K, while the top capture mode of the 800D is 1080p at 60 frames per second.

The 4K capture of the 850D is at 24 or 25 frames per second, not 60, but this is just what we expect from a DSLR. And, just like last time, video mode can use five-axis digital stabilization to obtain more fluid images.

Some bad news: when recording 4K videos, the focus is limited to contrast-based AF. As this loses the phase detection of the Canon Dual Pixel AF system, you will likely see some focus if you focus again.

Both cameras have a 3.5 mm jack for an external microphone and a mini HDMI output.

Value

  • Canon EOS 850D / Rebel T8i (launch price for body only): $ 749.99 / £ 819 (around AU $ 1,580)
  • Canon EOS 800D / Rebel T7i (launch price only for the body): $ 750 / £ 779.99 (around AU $ 1,511)

The Canon EOS 850D / Rebel T8i has a launch price similar to its predecessor. You can also buy it with a zoom kit, the EF-S 18-55 mm f / 4-5.6 IS STM, for $ 899.99 / £ 899 (around $ AU1,740).

Of course, these days, the EOS 800D can be found for around $ 200 / £ 200 less than its original online cost, which makes it a good value for money considering how close it is to its successor , at least in terms of specifications.

The Nikon D5600 is the obvious alternative, but, like the 800D, it is now quite old and has no 4K video capture.

The Canon EOS 850D is the best purchase for 4K video from a traditional DSLR manufacturer with a reasonable budget at this time. But there are many compelling rivals if you're willing to try a mirrorless camera. The Sony A6100 with kit lens can be found for much less, just like the Canon EOS M50 compact system camera.

Early verdict

The Canon EOS 850D / Rebel T8i does enough to keep the company's DSLR line in the present, by adding 4K video. Other improvements, such as a slightly better burst speed and a longer battery life, according to CIPA figures, are more enjoyable.

Affordable DSLRs may have lost momentum compared to the many mirrorless alternatives, but for now this is the obvious option if you want a DSLR with 4K video that is not prohibitively expensive and enjoy the traditional benefits of DSLRs, including handling and The battery life.
