mike i had about a 50% failure rate on these today ,poor light and a wood or the undergrowth affecting the focus didn't help ,when it nailed it it did well but wasn't easy by any stretch ,birds in flight against a clear sky is usually around a 98% success rate so there you see the problem ,canons do not like a messy background ,we can't have it allVery nice
I have to say I'm beginning to wonder if there is something wrong with the AF/tracking on my 7D ... while I rarely use it (I much prefer my Pentax K-5IIs and 150-450mm) I have never had a lot of luck with the Canon. The 50D I had previously gave much better results with moving subjects.
Works well at low shutter doesn't it ,quiet unreal but it seems a lot of us are finding the same
The two critical ones are ,for medium to long range shots set the focus to focus accuracy ,and set the stabiliser to dynamic .everything else is down to the users needsI must have missed the recommended settings, where are they?
having had a sport for longer than most in the u.k i have had ample opportunity to test my lens out on a lot of assorted canon bodies ,i have yet to find one that isn't spot on every time ,barring a 70d that i owned which turned out to be a camera fault .you would be better off doing any M/A IN CAMERA if there is consistent back or front focus problems .but first be totally 100% certain its not down to user error ,as a 600mm lens on a 1.6 crop body is actually at 930mm and it doesnt take much to throw it out of focus .A question for those that have done the focus micro adjustment using the dock...
I've got a calibration chart to set out at the different distances, what distance do I place it at for infinity?
OK at home in the application with lens docked I see no options for focus accuracy or stabilisation?The two critical ones are ,for medium to long range shots set the focus to focus accuracy ,and set the stabiliser to dynamic .everything else is down to the users needs

you have to go into custom modes C1 and C2 and set them as wanted ,its a ten minute maximum job ,just remember to save each setting to the lens as you go along .OK at home in the application with lens docked I see no options for focus accuracy or stabilisation?
Really nice sharp shots, another great advert for the Siggy. Well done!Thanks, @the black fox, it's mounted to a 5D3 and I had it mounted on a tripod. Good point though, I may just use in camera adjustment that way I can change it 'on the fly' without the need for a PC.
Actually yesterday was my 1st time using the lens and my 1st time shooting wildlife, I've so much to learn as it was like starting all over again. That aside I absolutely loved it.
The quality isn't great as the light was blooming dreadful...
