Canon 6D Does Skiing Shots

And again that's the worst kind of tracking one can possibly use.

Doesn't matter what you want to call it, automatic al servo = al servo with all points enabled and activated, starting from center point. That's basically letting the camera decides where to track.

Who uses that anyway? Anyone?

The camera does not decide where to track. You do.

One last time, at least for me. There are two scenarios on the 6D for AI Servo...

1. Any single point can be used to focus and track keeping in mind if the subject leaves that point, focus may be lost (depending on custom focus settings).
2. "Automatic" appears to show all pints activated, however only the center point actually is. If you chose another point the focus will not be acquired. You chose the subject to focus on using the center point only. If the subject you have chosen moves off the center point other points will continue to track and keep your chosen subject in focus as necessary.

OP, whatever camera, focus point, tracking etc. you used, those are great shots ! Every one of those would make a nice pic on a tourist brochure. The colours just explode !

Nice job !

Scenario 1 is what most people refers to when talks about 'tracking'. You as the photographer is to move the camera and continually plant that one point on your subject (preferably eye with people shot). That's why on cameras such as 7D/5D3/1DX there are expansion mode (5 or 9 points expansion) and more to assist you in performing this exact task.

On top of that, there are different 'cases' on 5D3/1Dx where you can fine-tune the tracking sensitively, speed etc to suit the kind of actions you are shooting.

Now the qualm with the 6D in scenario 1 is the quality, reliability and the lack of (outer) points on the camera.

Bear in mind 6D will track perfectly with center point in scenario 1, but not so great with the outer non-crosstype point.

And please just don't get started with focus recompose

Now scenario 2 is basically letting the camera to decide where to track/pass the point as soon as your subject moves away from center. This method is never preferred as once your subject you have chosen goes off-center, you lose any kinds of precise control of where to focus to be exact.

Let me ask you this, what happens if your subject's eyes are between 2 AF points in scenario 2? Surely the camera will pick the closest one, but which one and where exactly? One closest to head? prints on the t-shirt? Legs even? That's right, you have zero control on that and thus sacrifice on accuracy.

Having said that scenario 2 "might" work on higher end model such as 1DX due to its sophisticated and dedicated AF chip. Also the large amount of points (61 of them) and much greater spread with smaller gaps between point-to-point will allow more precise focus.

Great shots!

Or scenario 3, the photos the OP posted.......

And above is exactly the reason why it's never preferred

That's all I need! Your going to do this with a subject running around forward, backward and all around? Really? You are phenomenal! Hats off to you!

/thread jack with apologies to the OP - and I'm sure that I will regret this

mgk2, I'm really curious. Do you, moltengold, and bobbyz actually search out threads about the 6D autofocus so that y'all can "get your bashing on"?

It is my opinion that your method of information delivery does not convey a well-intentioned desire to educate the rest of us about canon autofocus. Further, it does not appear to contain the spirit of the forum rules which start with "Have fun!...We think empathy ,caring and sharing is cool..."

I see that you are relatively new here. It is my hope that you can chill and share your knowledge and photos in a way with less of a tone of challenge.

/thread jack ended

smmokan, your photos posted here are very nice... nicely composed, well executed by whatever means, and convey the energy and motion of the sport of skiing. I am very impressed.

It has nothing to do with how fast the subject moves.....

If you use scenario 2 and let the camera to pass off the point for tracking, there will simply be NO POINT to pass on that will give you precise focus if your subject's eyes are between any 2 given points. And that's why people don't use the kind of tracking you described in scenario 2.

Correct me if I'm wrong, but I believe Scenario 1 is the way to go for most experienced user, or any user who wants greater control with precision.

Sorry Dwain if I come across as bashing the 6D AF system, as I believe I am just stating the facts on how it generally works that's all...

The line you quoted me, a non-crosstype point will never be as good and reliable as a crosstype point and that's a fact I'm afraid....

It isn't something that I just pull out of thin air...

And if I've made anymore wrong claims or mistakes, correct me by all means?

They are great shots, even coming from a 6d.

It's hard to believe anything in motion was ever photographed 10 years ago...

Even 10 years ago the the original 1d had already been released making it now possible to shoot objects in motion. All praise the 1D series for finally making it possible in the digital realm.

I hadn't forgotten about the film versions either for all you old school shooters with good memories.

Is that ones with the real good memories of manual focus and if really lucky a 2fps autowinder...and colour film that had to be process as the same ISO setting for the whole roll( sure slide film could be pushed or pulled during processing, but for print film you were pretty much stuck on the rating of the roll - too bad if the lighting changed mid roll...)

So how did we get in focus shots of moving subjects back then?? (rhetorical question..no need to answer it)

Well then.... That escalated quickly.
