Originally posted by Harald Have you notized that batteries has quite an impact to focusing speed in these situations? When gauge shows half, speed is already reduced remarkably...
Yes, I have, and while I try to keep the batteries up, that's not always possible or practical when there are often games Thursday, then Sunday, a wife and two kids in between, lol.
Originally posted by Harald I do a lot similar shooting and my K10D and Sigma 70-200/2.8 EX DG DF have done it actually very well. In the situation you have here I would be very surpriced if I get similar (unsharp) results as you have got. The most difficult task is to keep the focusing point in the player and not let it slip to board. Are you sure that the F-point was in the player and not in the board behind him? Focusing point is actually quite a large, how big this player was in the screen? this picture you attached is obviously a crop?
No, these are not crops, just resized from original to fit the web better. This player is 5'9 inches tall and a good 175 lbs. I am sitting in the stands, higher than the glass, about eight rows up. In distance, the player is roughly 10-15 metres away from me.
Originally posted by Harald You have pressed the shutter button and let the serial shooting decide the moment of actual shoot. I do it little bit differently. I am not interested in any pictures before the very moment I want to shoot, continuous focusing holds the correct focus so that I can shoot at the moment I precisely want. Even with the speed of 5 /sec the best moment is very often between the frames, and with the speed of 3 /sec. it is almouts hopeless.
Usually I do not take more than one picture from one act. So if the AF-C doesnt hold the focus correctly I will lost this only picture. But it happens very seldom. Out of focus is rare cause of rejecting, mostly composition or the moment has not been optimal.
What you are describing, if I am interpreting correctly, is AF-C but not really using it. You're searching in AF-C, but really only depressing the shutter for a shot at a time. For me, that's a technique I use most of the game. But, in spots such as these, I do lay on the trigger and continuous shoot a good three, four, five frames in a row.
