Ever since the 100D came out, I have been planning to upgrade from a 70D. The only reservation I’ve had is AP1 vs AP2’s feature gap dramatically affecting my road trips. I eagerly arranged an AP2 test drive when 8.1 came out. I’ve had 17,000 miles in the last 8 months with AP1, and just finished around 150 miles of AP2 driving in a S P90D with firmware 17.11.10.
