Janis, those that can help you will need MUCH MORE info. Please. What focus method were you using? AI Servo?

try increasing DOF by stopping down lens and lowering SS, maybe 1/250...was he moving

did u sharpen the pic

looks like you focused on the fence. what lens were you using? could be its just slow to focus or unreliable.

Step 1:
Get the address of the picture, which since you already know how to do (it's what you linked above) I won't go indepth, but since you have a smugmug the easiest way is to click on the share in forums link. That takes you to a screen that looks like this:

Most people use medium (highlighted here) or large files.
Highlight the one you want, right click (if using windows) and choose "copy".

Step 2
Come back to the forum message screen and click on the icon that looks like a drawing of a mountain with a sun above it, shown here highlighted in red:


Clicking that button makes a little window pop up like this one:


Step 3
Since when you copied the link at your smugmug account you also got the http://in the beginning you can just hit backspace to delete it. Now you hit ctrl+v or right click (if you're using windows) and choose "paste". Now you should see something like this:


When you hit "OK" you'll see the image now appears in your message box here on the forum:


Or you can also write out the BBCode yourself which simply means placing "tags" before and after the address of the image.


Then, to make sure you did everything correctly hit the "Preview Post" button to make sure all of the tags are complete (when hitting "Preview Post" the images will appear).


Hope that helps.

OKAY first, magic, a tip on using the forum. You can ALWAYS find YOUR posts by clicking on your Name. You'd see that you posted this thread a few days ago, and so there's no need to start a new one of the very same exact topic. I moved your thread.

Now, I will look at the pic in Canon Image Browser and see what else I can find out.

What focus method were you using? AI Servo? How many focus points were enabled?

I used manual and I think that I used AI Servo with One focus point

So enable ALL focus points. And use good shooting form. Lose the tripod (not a benefit in this situation (did you use a remote release?). Hand hold it, and tuck your elbows to your chest.

Almost certainly the camera focused on the fence behind the player, since it has nice crisp edges with which to acquire a focus-lock on. And since shot at f/4.5, which means a bit shallow depth of field, would explain why the player, who is several feet in front of the focus plane, is not all that sharp.

I also agree with Andy. Ditch the tripod for sports. Its a hinderance, not a help.

Agree on ditching the tripod.

But I disagree on using all focus points - that's how you run into things like the fence being in focus but the player not - the camera selects the part of the image with the best contrast near a focus point - in this case that can be the fence. Use center only - but also realize you need CONTRAST - so don't put the center point over that white shirt - the camera won't be able to get a good focus. Use the head. And as mentioned, make sure AI-Servo is turned on.

I mostly agree with that but it depends a bit on the camera and the mode of operation. Consider a Canon 20D in AI-Servo with all focus points active. The initial focus lock will be the center point, without exception. The surrounding focus points are used only if the subject moves off the center point and onto a surrounding point. This can be a useful mode of operation.

I do not think my 1D Mark II behaves in this fashion. With that camera the preferred sports mode of operation is to have center-point only active. Not only does it prevent the problem of focusing on a background, the camera will focus faster if it only has one focus point to pay attention to.

But very good point about contrast and focus.

OOPS... needed too much sharpening!
