for someone with a9 looking to upgrade for wildlife, is there any reason to get the a7r5 over a1? used a1 is only about $1k more expensive. i can't see anything in the feature list that makes this camera better than a1 for wildlife aside from slightly more mp.
does anyone expect the AI AF to actually function better than a1? it wasnt clear from mark galer's review.
If the promo video is true, then it's a different kind of AF.
AI AF in A7RV has more types of objects defined that it can recognize, e.g. when there's a busy/blurry scene it has a chance of picking up a human silhouette (as it can identify hands, torso, legs, etc.). A1 needs to be pointed to that in order to start tracking it reliably (or at least that's my understanding, because it can only recognize face / eye). A similar example is given regarding shooting something heavy backlit, A1 struggles here as any other camera,while A7RV should have a higher chance of detecting the blurred shape as some kind of object it recognizes.
Now, once the target is locked I think A1 will retain its advantage in tracking pretty clearly (+ prediction/dynamic movement).
