With the Rebel T8i data loaded into our specifications table, the Canon EOS Rebel T8i / 850D can easily be compared to the Canon EOS Rebel T7i / 800D.
At first glance, I found the changes in the Rebel T8i uninspiring but, after digging in, discovered the overall improvements in the new flaghip Rebel model to make a solid upgrade.
Here are the differences:
- 4K video with clean 4K HDMI output
- 7 fps continuous shooting (7.5 fs in Live View) vs. 6 fps
- Eye detection AF in Live View
- DIGIC 8 vs. DIGIC 7
- CRAW vs. M-RAW, S-RAW
- AF working range of EV -4—18 EV vs. EV -3—18
- 220,000-pixel RGB+IR metering sensor vs. 7,560-pixel RGB+IR, 216 segments (18 × 12) vs. 63 (9 × 7)
- Spot metering uses approx. 2.0 % of viewfinder vs. 3.5%
- Built-in flash GN of 12 (lower) vs. 13.1 recycling in approx. 5 sec. vs. 3
- Many mode dial options moved the Special Scene (SCN) mode with new "Smooth Skin" and "Group Photo" shooting modes
- Rear control dial vs. control (arrow) keys
- AF-ON button, loses the WiFi and Av buttons
- NFC is gone
- Supports vertical video
- Battery life of approx. 800 vs. 600 (at 23°C, AE 50%, FE 50%)
- CIPA weight of 18.2 vs. 18.8 oz (515 vs. 532g)
