I have had a SX60 for more than 3 years now, and had the SX50 and SX40 before that. So I have always liked this line and felt each was indeed an upgrade over the previous. But to me the SX70 is the biggest upgrade yet. Both pictures and video at the highest settings are noticeably clearer, brighter and more detailed. When in auto mode, subjects get locked in much faster, so you can take pictures faster and still be focused. 4k video is amazing, I actually bought this camera for my son's graduation from Jr. College and I sat very far back to get a good angle. When zoomed in at 10x zoom video came out crystal clear in an outdoor setting and moving video was great too. Indoor pictures were also significantly brighter and clearer. Don't hesitate if you want to upgrade from a previous version or you just want a camera that can do it all extremely well.
