    John,

    The 11 point target mode has never worked properly for me - YET - but the 5 point , or cross, is what I am currently using.

    The reason I have settled for 5 point is as follows:
    To shoot wildlife moving objects requires hand held shots as you need full freedom to follow the subject.
    When using a long focal length lens the angle of view is very tight and it would be imposible to track a subject on the centre target alone. Using 5 targets increases your chances of keeping the subject within the target area and hence maintaing focus during the burst of frames. 11 targets is just too large an area when covering a small subject and the AF may pull off and be attracted to another unwanted object. I am working on this at the moment.

    Other things to consider:
    Make sure your AF is not pulled by sudden changes in focus (see Wrotniak article). I keep this as a permanent setting.
    Study the subject before shooting, even doing a trial track first.
    I keep IS1 mode on as my shots are hand held and I have never had a problem with this setting.

    Hope this helps.

    Its good light today and a good opportunity to give it a trial.

    Peter

    Thanks John. The important thing with C-AF is that you must first lock onto the target with a half press on the shutter BEFORE taking a burst of shots.

    Nice clear image there Peter, you have shown very clearly that the C-AF mode works well.

    Re: Continuous AF on the E-3 - Update 21 September

    I went out on a shoot with PeterL Saturday afternoon and took a series of C-AF images of Swallows in flight over the lake at the Water treatment plant, Southmoor.

    I chose the swallows as they are fast fliers and at about 100yds distant, very small and difficult targets to track. This I thought would be a good test of the C-AF (and of course the lens and camera). I have posted one image in the gallery and re-produced it below. I have put the settings used in the photo description for those who are interested. In this sequence, I took a burst of 6 shots with two failures but the rest were clear. I have selected this image as it not only demonstrates the clarity of the bird but also the clarity of the reflection in the water.



    Using any other shooting method would have failed to capture anything and offer this to encourage others to use this mode.

    It lasts approx. 10 minutes and Chris Weston gives (I thought) some pretty useful information on setting up and taking photos of wildlife. Although done at a bird of prey centre, the information can be applied to all aspects of bird photography. I found it very useful as it got me going on using C-AF etc.

    Cheers

    thanks for posting this. It was very useful. Lots of insight and good to watch.

    I must admit that I usually use the centre spot myself. I sometimes use the diamond selection, more rarely all points. Centre spot works for me because I have found that some of my focusing difficulties occur when I use either of the other two settings.

    I have to say that I too am still very much experimenting with different methods, still trying to find one that works. What I am finding, though is that there seems to be no one way that works for all occasions!
    I have found more success with the centre cross. The reason for this is that I am using a Bigma and the total weight is such that to accurately position the bird at the centre spot is difficult when hand holding.

    The video was excellant. Thanks for posting it.

    The only time that IS is switched off was when taking shots on a tripod. This makes sense from my experiments although I do not use a tripod myself. The camera/lens in use did not seem to have an option to switch off ISO in one of the planes (ie IS 2). Now this is an area that is worthy of further dicussion. So, to sum it all up. Thank you Thea for posting your comments and the link. You are doing far more in bringing out the conversation regarding C-AF so please do not feel you are out of step. You definately are not. This is the sort of topic we older hands used to discuss in depth and its great to see this happening again.

    Well done and thank you.

    The manual seems to say that if anything passes in front or behind the camera should maintain focus on the subject.
    I think the default is off.

    Sorry if this has been covered before.
    Andy,

    I set this to ON. It seems to work as you pan. I have included extracts from the Wrotniak website which I think pertain to this type of shooting in an earlier post in this thread. The choice IS 0,1 or 2 I have not decided on yet. Feedback from others may help me decide.

    When it comes to focusing, my main problem is my 50-200mm lens (which this picture was taken with, which makes it even more amazing ).

    For birds in flight I use not only C-AF and IS1 (or 2), but I also set the camera to sequential shooting (high). Even so, when I press that shutter, I don't know if the lens is going to 'play ball', or decide to go hunting again (I lose more shots that way ). It's just one of the limitations of my kit - particularly if there is not enough contrast for the lens to latch on to.

    Then, if all goes well I can get some shots (my husband is usually highly amused - says I look like a crazed gunner, frantically following these birds round the sky . I beg to disagree ). Rather than rattle off loads of shots, I usually fire off short sequences, which also gives the images time to clear the buffer (I shoot in RAW).

    My methods probably go against all the 'rules' of photography, and yes, in reality you should make each shot count, but subjects such as birds in flight are difficult to achieve. I also take the view that the beauty of digital photography is that you do have the luxury of taking enough shots so that you do get something you're happy with without wasting a lot of hard earned dosh on film!

    I also normally use IS1 when taking birds in flight, but recently decided to try IS2 for this subject, and it seemed to work quite well for me. Perhaps I just got lucky this time, but here's my effort using C-AF and IS2:



    Thanks for looking
    Well done Thea. Great shot.

    I think that some of us are still stuck in the days when we had to purchase film for our cameras and expect 100% success with our shoots. You have summed the situation up precisely when describing shooting birds in flight. It was the reasons that you give that I started out again with C-AF. If you lived through the times we early purchasers of the E3 had when focussing was a major issue you would understand why it is that we had been reluctant to use anything but S-AF.
    That said, looking at it logically, its the only way to get that special shot by taking a series of C-AF images and examining them to select the best. Single shot S-AF is just like a roll of the dice - have you timed it well and has the camera captured the moment you intended. Some things happen so quickly that you do not get a chance to react.
    I did not manage to get a flock of birds in flight but did manage to capture a herring gull fishing and eating its catch. I shall post some frames later.
