    Good point - shouldn't be an issue from default, but worth checking. I wish manual would allow you to set Auto ISO and allow EV correction!

    The position of the bird within the frame for the first two shots is about dead centre, and in the subsequent two shots the bird is more to the rear of the frame.

    This can only come from panning too fast causing the centre focus point to move off target - thus poor focus. :\

    I was just about to suggest that! The main thing is that you have got a good keeper from getting none at all. As I say, practise!

    Cheers

    Did use just the centre point, 'L' mode and all of the suggested setting.

    Given the first shot isn't in focus, it suggests that you didn't get a good lock in the first place - hence my tip about following the bird, shutter release half-pressed, followed by a short burst when you have a stable lock.
    I actually heard the bird coming before I saw it. I was able to get the camera aimed at the line of trees before the bird appeared. When it did come into view I was abel pan it across the road to the line of trees on the other side. The possibility that I didn't hold the button down long enough to get a proper lock does hold, and could have been the case in the excitement.

    The other thing is to blow out the mirror box - particularly the AF sensor at the bottom with a hand blower - dust on the sensor will make it jump about.The 50-200 SWD tends to be twitchier than some of the other lenses.
    I will get a hand blower and give it a clean. I certainly do notice the "twitchiness" of the lens, but a small flaw for the quality - but needs to be taken into account.
    I've had the E3 for about 15 months and use it at every opportunity I can get. It hasn't had a clean out since I got it, so maybe it's well due.

    As much as anything, you need to practise - a stable panning action will help no end.
    Given that my E3 was set opposite to every suggestion you made, and I had been trying to shoot C-AF like that; the sample I posted I consider to be a definate move forward. That I got one keeper in the first attempt is great!
    No doubt, as you say, practise will make perfect. And, when the practise has achieved my goal, pracitse some more.

    It may be as you said in your suggestions:
    "There is a major drawback, you need to have the skill and practise to keep the AF point on the moving object (in the worst case, the same bit of the moving object)."


    Many thanks Andy.

    Whole point of this exercise is to show the results of my first attempt at C-AF after setting all your recommendation on my E3.









    As you can see, the first shot was slightly our of focus; the second was pretty sharp, while the third and fourth drifted out of focus again.

    The good news is that I got a keeper, but C-AF continues to re-focus during a burst. It corrected after the first shot then went out again for the third and fourth. Any ideas as to why it would do that. As you can see, there was nothing to get in the way of the subject to cause the re-focus.

    Any wisdom would be appreciated.

    I put in the path to the images on my computer, but no go. :\

    Guidance would be appreciated.

    That means if you have an image stored on another web server (i.e. something beginning with http:// etc.).

    The best way is to upload to the gallery here. Click on the "Galleries" header, then "My Photos" then "Upload Photos" ( the last being on the right of the web page). You then have a page where you can upload up to 5 pictures at a time (click the various browse buttons to find the JPG on your PC, then 'Submit/Upload'). You can optionally choose to add it to an album you have previously created (not an essential step) and categorise it as well. Once the upload happens, you should see you set of images where you can add comments, if you want to, then press the button at the bottom of the page to commit them to the gallery.

    Once they are in the gallery, you can include them in a post by first clicking 'Go Advanced' rather than 'Post quick reply' and pressing the 'My Pics' link on the right of the advanced posting screen. A pop-up (make sure pop-up windows are allowed for this site in your browser) appears showing a list of thumbnails of your pictures together with a drop down as to how they should be inserted into your post (e.g. a thumbnail with a link to the gallery or the original image etc.) when you click on the image.

    I think that wraps it up - I'll add more if I think of it.

    Thanks Andy, I look forward to a higher keeper rate. Never was that sucessful with c-af. Hope this evens things up a little.
