The Canon SL3 was launched this year and has a couple of improvements over the T7i, but it also has some setbacks.
The biggest differences I could find are the image processor, battery life and autofocus. The SL3 has a new DIGIC 8 image processor compared to a DIGIC 7 on the T7i. The battery life in the SL3 is longer than the T7i, 1070 shots versus 600 shots (under the same conditions). However, there is a trap. The T7i has 45 cross-type autofocus points, while the SL3 has only 9 regular autofocus points (one of which is cross-type). However, the SL3 has a dual pixel autofocus, but that only works in live view.
This will be my first camera. I wish I could film anything from portraits to children running (hence my concerns about autofocus) and sports from time to time. Live viewing can be a great way to start photography, but I think I will probably only use the viewfinder later, which will make dual pixel auto focus unusable.
I don't care about the slight difference in frame rate, 5 in the SL3 and 6 in the T7i. I will also take photographs mainly, but when I record videos it will only be in 1080p due to the cropping factor and the lack of dual pixel autofocus in 4K.
Two specific things I would like to know:
- How does the autofocus on the SL3 compare with the autofocus on the T7i (both for photo, with and without live view, and for video)?
- What difference does the new image processor make (in low light)?
How do these two cameras compare? Is there a difference in the overall image quality? Is there any other difference that I missed? What would be the best option for me?
I will shoot in RAW.
