Autofocus or not – plus other questions

Hi all, just wondered if some of you would share some knowledge.

Q1) On the shots where your subject is clearly at infinity, do you set lens to infinity and let DoF do it’s duty or let the AF work?

Q2) I have a Canon, I note a lot of you guys do to. Do you have the AF (Pending Q1) set on “One shot”, “AI Focus” or “AI servo”?

Q3) To get your stunning panning shots, do you set the camera on single shot or multi – the latter of course gives you more hope of a perfect “No camera shake” shot whilst panning at Airshows etc.

I am not a newbie to photography, been taking since 1970, cut my teeth on a Zentith!! But, I never did master perfect Airshow pictures, sticking more to the abstract such as close-ups of fuselage detail and such.

(Don’t tell me your lenses, I go green. Your lenses cost 5 or 6 times my BUDGET for a car!)

In answer to your questions,

1> I let auto focus do its work.

2> The camera will generally be set on AI Servo.

3> The camera will be set on High speed advance, however I will try to stick with taking single shots, although not always!

I hate to say this but the attached was a perfect example of point camera and press button. I thought the aircraft was leaving the circuit, instead he turned and did a low level run down the display line, I just lifted the camera, framed the aircraft and pressed the button, I just hoped it was in focus!

Regards
