Just another great example that BEAF works in the hands of a bird photographer unlike in the hands of a YT clickbaiter.
Thanks Alex.
This looks very similar to R5. When the operator pans the BIF smoothly enough the system can do eye af for BIF. If the operator is a bit behind or unsteady the system resorts back to dancing dots or in the Sony case RTT. I’m not seeing anything that looks worse than the R5 here. Keeping on the eye for the Osprey takeoff was looking good
The advantage of Sony's BEAF implementation is that you have full control over the "watch area". If you use a smaller area like Alex used in a lot of this video then it only looks in that area to see if it can find a bird/eye. But the genius is that it then seems to be able to keep focusing on that eye if you recompose or the bird moves outside of that initial watch area. The R5 has two options....full sensor watch area or a Single Point (about the size of Sony Flex Spot Med) in which to look for a bird/eye. Sony has the advantage here with Zone especially and event Expand Flex Spot, Large Flex Spot and even Small Flex Spot could help in some cases. With Canon I have to setup a 2nd back button to be Spot AF but that doesn't activate Eye-detect. I have to focus on a bird in cluttered surroundings with the Spot AF and then switch back to my Bird Eye AF button to help out the system "See" the bird. With Sony you can use Small Flex Spot that you can not only target onto a bird in clutter but it also starts the EyeAF without switching back and forth.
On top of this the Sony has the option to layer on RTT to any of the AF modes and have Eye-AF working in conjunction. Just way more options with the A1's system that will be a big advantage to a photographer that understands the different situations and doesn't just wander around pointing Wide AF at everything expecting it to work all the time
