You won't ever have all the focus points active at any one time, it'll target the area around the main subject / movement. You'll never have a completely flat focal plane using all AF points unless you're shooting a flat piece of paper on a rostrum setup!
Thank you, I was wondering if there was a compatibility issue between the 80d and Sigma as the 80d manual says:
"Although the camera has 45 AF points, the number of usable AFpoints and focusing patterns vary depending on the lens. The lenses are thereby classified into eight groups from A to H.When using a lens in Groups E to H, fewer AF points will be usable."
Can't seem to find any info on what group the Sigma fits in.
