EOS R5 Mark II Spot Detection for military fast jet photography ?

[Alan7]

Hi 👋 

A question for my fellow military fast jets (aviation) photographers please ?

I am setting up my AF settings in my R5 II, and in the “Vehicles” Subject To Track setting, I am in between two minds whether I should also enable the Spot Detection ?

This is because, the manual says that this particularly spots the aircraft cockpit. That would be great. But when for example a manouvering jet fighter in flight, turns and banks sideways to show the underside ? Would the AF still continue tracking and focusing on the general shape of the aircraft, without losing focus, or would it be searching for the cockpit and lose or diminish focusing ?

Should we (aviation photographers) enable the Spot Detection or not ?

Thanks in advance to those who already surpassed this uncertainty, and may share their feedback. 
Alan.

I would say it is unlikely to be helpful, as you are not going to be close enough that focusing on the pilot is any different than the whole aircraft in terms of distance. 

Check the section about subject detection in the AF settings guide on the Canon website, it's surprisingly helpful. I've put a link below to the right part of the guide.

Hi Brian, yes I can understand what you mean about the overall distance to the aircraft rather than the cockpit area specifically.

I had thought about not enabling the Spot Detection for fighter aircraft anyway.

Thanks

I shoot small verry fast birds and the only way I can track them is to set AF to whole area and it will look for an eye if no eye then a head and last the whole body.
