Hi,
Last week I had to opportunity to go to an airshow near Paris.
While some of my pictures are really stunning with lot of details and contrast, others are more soft.
If you look at the picture of this (amazing) spitfire, you will see what I'am talking about.
I know that my lense (DA*300mm f/4) si capable of better performance, so I wonder what is cause of this softness. Is it bad focussing? Mirror Shake? IBIS side effect? Motion Blur?
This picture was taken in RAW at 1/2000, F4, 100 ISO, hand handeld and with shake reduction ON.
Any help is welcome to avoid this kind of problem next time
