guys i know its out of focus, im wondering how/why it would have been out of focus. was it me? lens? camera? i shot 1/4000th at f2.8 which is very fast. i had the camera to center dot metering and it was set on af-c. what went wrong is what im asking about the wheelie pic. i didnt attempt any panning at all except the last shot, i wanted crisp still shots. that was my intention, no action.
I suspect this is what went wrong. AF-C is continuous, right (I shoot Canon)? Normally there's nothing wrong with that, and that's what I use most of the time.
What happened was, the selected AF point was covering the background, not the rider. Think back and try to remember how that happened. Which AF point were you using? Did you try to focus and recompose without stopping the AF?
There are a few ways you could have still got the shot.
-You could have selected a more appropriate AF point (pick the one closest to where you're going to put the rider in the frame, then just follow him, keeping the AF point on him the whole time)
-You could have focused then recomposed (you will have to enable 'back-button focusing' to do this with a continuous AF mode)
-You could have focused manually (does that lens allow you to focus manually while it's switched to AF?)
Also, something like this, you
should be panning to follow the subject. With shutter speeds as fast as you were using, you wouldn't get much background blur, if that's what you were going for.
Panning to follow the subject might have also saved #5 by keeping the AF point on the rider as you were focusing.
