@wildfire,

the only points I would contradict you on is needs --- if you shoot landscapes or shoot in the studio - where the light is controlled or a tripod is used often then high ISO is not a selling point, IQ is the only game changer for you.  If your that shooter then there is no reason to use anything but a 5d2 because low ISO IQ is about the same between the 5d2, 5d3 and 6d.  Also, most of the 6d deals I have seen are just shy of $1800, without tax/shipping.  Most good retailers will have free shipping on an item like this (and being in NY state its rare that I have to have anything shipped from B&h expedited).  6d with tax is closer to $1925.  Used mk3 is closer to $3k.  New is closer to $3300.

@RLPhoto,

I don't get your insistence on this issue of bashing the 6d in all cases.  You don't don't seem to take into account what eash shooter is looking for and what kind of budget threshold each of us have.  Don't get me wrong, I am still considering another 5d3, but it is going to come down to cost.  As another user pointed out, in my personal situation:

Dual 5d3's + current glass = good photos
5d3 +6d + better glass = better photos

That's my threshold - if I can find one of these refurbed mk3's for under $2500 I ca still make moves with glass. Over that and glass upgrades fade away until next year.  Where a 6d means I can upgrade glass now and it still leaves me the option to snag a second mk3 next year.

Just picked up a second 6D because of this sale.  I am going to sell off my 5D2 and use two 6Ds for now.

IMO, I prefer the 6D with his slow AF + great image accuracy... I don't care about speed, I do care about image quality (not having out of focus problems)

I don't know what the fuss is over. I was nailing keeper after keeper today with my supposedly horrible 6D and my completely unusable Tamron 70-200.

Which af points were you using?

All modern af system are usable, the differences should show a) when the tracked object is to the top/side (no af points on 6d), b) when the contrast/light is low (only up to 0.5lv and no outer cross on 6d), c) on difficult movement patterns (i.e. not simply something like a wave moving constantly in one direction).

However I expect the 6d to do just fine for me once I got it, I recently got frustrated by my 60d again because the af fields are just too far apart so it's center point only for tracking - which works, but at least on 6d the points are closer together so multipoint should be more usable.

Center Point only, continuous shutter mode, one shot AF mode(because the Tamron lens does not function well in the AI modes)

Well, in that case the shot could have been taken with just about any dslr or p&s, esp. since the light was good and the aperture small :-p

That could be said about a lot of the photos posted on here to show how great such and such a model is.

Absolutely, that's why I personally never post pictures in a tech thread, it doesn't man anything most of the time except if the full picture series without postprocessing is given for "keeper" evaluation and maybe 6d and 5d3 are used in parallel or after another for the same scene.

You can post "negative" problem pictures to show what went wrong or where you think a camera fails, but except for high speed action scenes or very bad shooting conditions (af lock, dr, iso noise) any recent dslr is able to produce decent pictures - just not with the same reliability or usability.

I haven't been using the multipoint AF on the 6D much ... It's been focus and recompose for most of the time. I decided to put it to test earlier this morning and was pleasantly surprised with the number of keepers I got - I have derided the AF of the 6D at times in the past but I must say, it's reasonably good and people with more skill than myself will definitely get more keepers out of the system.

The multipoint AF works best in good light though. If the light is not good enough, it is difficult because the AF points other than the center AF point start to hunt back and forth and you lose possible shots in the process.

That first image in particular is a very fine example of focus.  Nicely done!

All you need to do to increase your keeper rate with the 6D, is set "second image" to more accuracy rather than speed (in the autofocus menu).  It will slow the frame rate down, but so what?  Basically all the frames will be razor sharp.  I admit I'd like to have really fast frame rate and accuracy sometimes, but most of the time I don't need a lot of fps.

If you need more responsiveness on the 6D, set "C.Fn II:Autofocus" under menu #1, all the way to the right, "responsive".  I'm also using "accel/dec" tracking all the way to the right.  First image priority is set to the middle, but second image priority is set to "focus", again all the way to the right. 

With these settings, and center point only selected, I was able to track my cat running at me in very low light with only an f/4 lens (ISO 25,600).  My shutter speed was too slow (1/100), but in slightly better light, it would have nailed him.

Birds in flight are very difficult, but I've snapped quite a few.  I congratulate those of you who do this!  The smaller faster birds, are the difficult ones.  Larger birds are easy.  I've even snapped some bats in flight at dusk, with my 135 f/2...but the animal is not pleasant to look at.  Of course it only works with sky as the background, unless they happen to come out early enough.

Finally had a chance this weekend to test out the horrible AF of my 6D.  Used AI Servo with back button focusing in single shot mode.






The camera didn't have any issues taking these photos.  The hard part was keeping the focus square in the right spot.  Only issue with blur I have is shutter speed.  I don't take pictures of this kind of activity very often anyway.  The low light performance is why I bought this camera.
