Hi All,
I went to the Duxford Airshow 80th D Day Anniversary on Sunday 02nd June which IMO was the better day for the British weather. It was so good the weather I did catch a little too much sun on the day !
I went armed with my Canon R7 paired with Canon EG 100-400L f4-5.6 Mkii IS USM, and a Sony A6600 paired with a Sigma 18-50 f2.8 for planes taxing passed the crowed.
Perhaps I was a little Naïve thinking that mirrorless Subject Tracking AF would be like an Exocet homing in on a Royal Navy Frigate. Either the canon subject tracking on APSC cameras needs tweaking or I am really not using it properly, so can some please please let me know what I am doing wrong.
below is one of many images which are just not in focus while in subject tracking and the R7 has IBIS !
Setting 1/800, F8 ISO 100 400mm focal length, Tv mode, AF point single expanded image has been cropped
Settings 1/1250, f8, ISO 100, 263mm focal length, Manual mode
The shot below is better image, though I was expecting pin sharp !
1/100 f8 ISO 100 (auto), 400mm focal length, Tv mode, AF point single expanded
I am sure the 1/1250 will freeze the action better than 1/800, However a prop war bird at 1/1250 will freeze the propeller as the aircraft are not at or near full throttle. However IBIS though stated at 4 stops should at least give me 2 stops or at a push 3 stops. Therefore my 1/800 on an my 7Dii would have to be at least on 1/1600 at f8 ISO 100 !
What am I doing wrong ! ?
All advise will be very mush appreciated as I might go back to Duxford Battle of Britain Airshow later in the year
Many thanks
