Understanding AF profiles and its customizing

I have had the SL2 now for the last 9months and haven't yet changed teh AF profile from the default Children/pets option.

I have varied success with moving subjects, like running children, children on swings. Any further guidance on tweaking the AF profile across its three parameters for birds in flight , children on swings would be much appreciated.

Up until now I've found that I have far greater success with MF tele lenses. However with AF lenses specifically the VE 90-280mm L, I've recently started experimenting with various AF settings in an attempt to improve the hit rate, especially with birds in flight.

I'm starting to have some success with the following settings & am still learning-

AFC > Tracking > Drive Mode =Continuous Medium Speed > Centre-Weighted Metering > Aperture =f8 to f11 > ISO set to 800 or higher (post process with Topaz DeNoise Ai) > Avoid situations with back lighting.

 Just need to keep practising to get it right & to break old habits...

Have a read through this thread:

If the SL is anything like the CL, setting the shutter to electronic will vastly improve the focus tracking.

That's interesting...any idea why?

I have no idea. It was an empirical finding.

Any noticeable distortion from the electronic shutter with moving subjects?  I suspect the readout speed isn't all the fast.

Of course that is a consideration, however, as things like birds and running dogs don't move at extreme speeds as long as one stays away from Cheetahs, Perigrine Falcons and Golden Eagles, nor have geometrical shapes, it won't have a practical impact.

Interesting. My experience on higher shutter speed (> 1/1000) improves AFC tracking.
