Looks like the OP is done with this thread. So what need can further postings fill, however constructive they might be ?

Hey Everyone.

A little perspective, for me anyway. Just found out a good friend has cancer and doesn't have too much time left. Bummer.

David,
good people like you have helped me immensely over the past 6 years. I have read many of your posts. Thanks and keep them coming!

Grant

I propose a "FM Conflict Resolution Room" where if a discussion gets out of hand, then all parties involved get locked into a virtual "time out room" until everybody kisses and makes up

AlyceNWndrlnd should take a few sample shots directly into a mirror. I am confident the source of the problem WILL be found in one of these shots.

Although I agree but it is simply not feasible without an active full-time moderation .

The OP didn't describe the problem clearly and used "non-standard", confusing terms in his/her description. It didn't get off the ground that well. Oh, well.

I shoot with a high quality tripod and a remote. No IS. In 2.0 - 2.8, focus is sharp

Problems are most often with my EF 24- 70mm L USM


Can anyone tell me how to get my 24-70L USM to shoot at f/2.0-2.5 with IS ?

And FWIW David has helped me out with many things in my time here, if you ask a sensible question he'll more often than not give you exactly the answer you need, what's with all the new / low post members thinking it's appropriate to throw personal insults around at one of the most regular visiting and helpful members of this, or any forum ?

I think that most of us believe the problem here is with focus point placement rather than with the shutter speed, Alistair...


Thanks for clarifying that Keith, I wasn't actually asking you anyway...

Originally I thought it was a shutter speed issue until the OP wrote later that he had cropped 2 thirds, up to that point it was a logical assumption.

Either way, I think it is a combination of both shutter speed, or lack of it, and focal placement error. For that kind of shot 1/50s is really too slow as the subject is laughing and moving. Each to their own.

The AF points on the MkIII are larger 'than advertised' i.e. they extend past the red box. In some situations you can get back focus because the sensor is more interested in the high contrast stuff.

Secondly, really bizarre focus shifts can happen with the 24-70 if its collars get broken. This can be manifest as softness and smearing.

Well, this was an interesting read!! I have just spent 20 minutes on DPR for my daily dose of vitriolic $hit and then came to the calmer waters of FM and what do I find? - one of the most stupid threads I have ever read. I really do not understand why some of you guys with good "cred" get involved in this sort of thing.

Dave was "right on the button" - the O.P. should not only get a good introductory book on digital photography, but also a a simple DSLR and "learn photography". If you put a learner driver into a Ferrari you can expect nothing but problems.

I sincerely hope that this forum is not "on the slide".

Well, Colin, people like yourself, Lide and I, to name but a few, will not allow this forum to slide to the level of some other internet boards.

Now, back to photography, lads.
I think my MkIIN migh be afflicted with an AF "issue".
See the enclosed photo. I placed the centre AF point on the very contrasty goose, and the dumb camera focused on the duck ?
What gives ?

It's a sad day when the experienced, knowledgeable members of the forum have to pick and choose where and what they post in case they accidentally tell someone that they may not, in fact, be the most naturally gifted and talented photographer that's ever lived, and that maybe, just maybe, there's a few more things in the world to learn yet.

If you use DPP you can _check_ to see which AF point(s) fired. That would be a good start - if they were not on the subject but instead on the background... "we have a winner."

If they were on the subject then we can explore other possibilities.

And, how about if all posters on both (all?) sides of the personal stuff just let it go, OK?

Well Pete,

I really think you should buy a specialist book on photographing Mallard and Canada Geese!!!

Only joking, more info needed to assess the problem here.

Best,

Colin

Well, I don't see the original picture anymore, or I would be able to give better advice here.

Were you taking a picture of still subject(s) with your cam on a tripod in AI-Servo mode? If so, the focusing mode is probably your largest problem. AI-Servo is meant for moving objects. On top of that, the 24-70, while a wonderful lens, is notorious for back focusing on higher contrast backgrounds. Ya gotta work with it to get it to do what you want it to do. Once you've mastered that, it becomes a great tool.

Many of the photos on my website were taken with the 1D3 and 24-70, so I'm very aware of all the little quirks, and have learned to work around them.

Blessings,

-Jimmy

Colin, I was joking too, it's a prank shot. The camera is good, but it is I who loses focus all too often.

This was partly my point Chris, and looking back again at the start of this thread I would not have responded personally and neither should anyone else - leave dieing things to die in peace, do not keep the flame alive.

In retrospect, this might even have been a "troll" post.

I attach a shot of a scarce and difficult to photograph species (Spotted Crake, Porzana porzana, at Lagoa dos Salgados which I found recently) - much better than arguing, yes?

Good shot of a rare bird, Colin. Nice to see a bird photo which looks so resplendent in its "naturalness".
