  • C-AF - The Good News

    Found my friend the Kestrel this afternoon and took some 90 shots of him using C-AF, 5 frames/sec, and ISO's 400 & 800. I only lost 2 shots due to focus problems. A very good comparative performance with the S-AF mode. I have selected at random two consecutive sequences in burst mode at ISO 400 and ISO 800.

    ISO 800







    ISO 400









    This makes the E3 shoots extremely flexible. It also has given me a great deal of confidence in the C-AF mode.

    Cheers

    Very good Peter - you've obviously nailed using C-AF correctly. Very clear and detailed!

      I'm finding that I get good results using C-AF on the E-3 with the central five AF points active. I feel the upgrade to the latest firmware has helped too.

        Thanks Hugh.

        Now I hope not to miss as many opportunities. Candid shots become a very real posibility.

        Cheers

          Ian,

          I agree. I have tried virtually all combinations and the only one to give reliable results is the 5 centre spots. All other options are a no no.

            Almost missed this - what upgrade Ian? I may well be out of step here.

              It's not very recent - v.1.2, see:

              http://www.olympus.co.jp/en/support/...firm/e1/e3.cfm

              There is no claim that AF has improved with the upgrade.

                Thanks Ian,

                I have version 1.2 installed. The C-AF change happened around the beginning of the year with release 1.1.

                I was a bit concerned I had missed a trick while I was away from the site

                Cheers

                  Do I understand that you are getting C-AF to work when panning on the subject rather than or as well as when the subject is approaching the camera?

                  If so I must go seek out some birds to try it out.

                    Precisely correct Derek. There was almost an unwritten acceptance not to use C-AF when our confidence was severely knocked at the end of last year. I, like a number of others, continued only to use S-AF.

                    I like taking action shots and found it very difficult judging when to half press the shutter and take the shot when a subject was not stationary. This made me have another look and experiment with various settings. The result are as you see it on this thread and http://e-group.uk.net/forum/showthread.php?t=2833. It was only after the shoot today that I felt confident I had a repeatable set up.

                      You are absolutely right here. My confidence was knocked by the huge number of comments on many sites about CAF being hopeless. I had my own focus issues (which were a bad camera) and I have never been able to untangle the facts from the doubt. I will have a try, with the results you are getting proving it is worthwhile, this is for me what the forum does best. I can see what you are doing and it works.

                      On another thread there was a helpful message about using the settings that give you the 5fps burst and just pan. I confess I have never tried the burst mode. I assume that is what you have done here... but at 500mm with 2kg of bigma and an E3 hanging off of it you deserve a round of applause (or beer ) for the physical effort and super results.

                      PS how do you make friends with kestrels? especially with the dog there!

                      best wishes

                        Peter,

                        Thanks for your comments. The way I am looking at it is that I have complete freedom to pan and get a frame rate of 5/sec of high resolution images. The chances of missing an unplanned special moment are very much reduced. this is very important for we wildlife photographers.

                        Peter

                        PS. This afternoon, Blade (my dog) dutifully followed me up the hill and towards the Kestrel. The Kestrel spotted us and, rather than just fly off, swooped towards Blade. I wish I could show you his reaction, he shot off and the Kestrel carried on hunting. I think the bird has got the measure of the dog now.
                        On this note, I have to say that Blade is very well behaved and when he sees me taking photos he just sits or lays down. In the past it would have been a race to see who could get to the target subject first.
                        Best Regards

                              Nice pictures of the Kestral.

                              Sorry to throw a spanner in the works and it may be me mis-understanding the manual but I though that when you were in burst mode be it 5 FPs or other the camera locked the focus ,exposure and W/B on the first frame.
                              All the best
