The RX10iv is a very capable performer but as an a99ii owner I can’t help being a bit disappointed that it out-performs the a99ii at AF tracking.

It shouldn't be surprising since the 10iv uses the same processing and algorithms as the A9. The A99ii is an older design. The 10iv is amazing the way it sticks like glue once you lock on a target.

Don't you think also that because the 10IV has a small sensor with deeper DOF it has an inherent advantage over the A99II and its FF sensor?

No I do not because even small amounts of misfocus at 600mm equiv. are noticeable with the RX10iv. They are just more obvious with the A99ii. The plain fact is the RX10iv AF is lightning fast at all focal lengths and once it locks on it sticks like glue. I use the same lock on expand flexible spot mode with both cameras. The fact is the RX10iv has more powerful processing than the A99ii combined with the more advanced algorithms from the A9. In addition the RX10iv, being a fixed lens camera, has the advantage of being integrated with a body that are precisely tuned to each other. The A99ii has to accommodate a wide variety of lenses. Don't get me wrong. I love my A99ii with it's fantastic IQ and it's AF is very good, just not amazing like the RX10iv.
