Re: Go for the 800d or 77d

For indoor sports the 77D is definitely better. AF of just about any SLR is better, although the most recent m43 cameras are much better. G80 is pretty good, but like all contrast detect AF system has troubles in continuous AF. Could pose a problem shooting sports inside.

Reading the DP review review of the 77D I understood the AF with OVF wasn't so good at subject tracking (ITR I believe it is called) They actually recommended live view instead. Can you explain your different viewpoints?

Thanks!

I think this refers more to video shooting. Also, "not as good" doesn't mean it is bad. Live view means that what you are looking at is what the sensor sees. I suppose the OSPDAF which is dual pixel is very much active because of that. With the mirror blocking the sensor and likely the shutter closed, I suspect the AF is bound to be different.
