New 7D II or 6D

I have had a 7D which I use for basketball games in some very small poorly lit gyms and I have GAS for either the new 7D or 6D. I use the Canon 24-70 and 70-200 L 2.8 lenses and am wondering if I'd be better off using the 24-70 on a 6D with the 70-200 on the old 7D or should I go with both 7D's. Would a full frame camera in closer up situations be better than the crop sensor? Please help me decide as basketball season is getting closer!

If you are shooting sports then go with a 7D or better yet the new 7DII. The 7DII with the 70-200 2.8 would be a killer combo for basketball I do believe. The 7DII also has the ability to sync with the pulsations (invisible to the eye) of many common types of lighting producing more consistent exposure and color rendition. The 6D is better in low light but lacks the focus ability for action shots. It's a great camera. I love mine, but it is much more difficult to shoot moving subjects with it then the 7D's.
Ken Rockwell has a good run down of the 7DII features:

I have to agree, the 7dII would be a better choice for your indoor basketball games.

R, if you shoot sports, why are you EVEN asking??!! You are using a pure-bred sports camera and you're thinking of trading it in for a landscaper??!!
Don't kid yourself, you can not shot sports with a 6 unless you are a masochist for your shots.
You are comparing ONE cross-focus point to 65 Cross points. What of that do you NOT understand?
Yes, you will get those that shoot sports with the 6 and say it works.
There are shots of sports, and there are sports shots, don't confuse them!
I've been shooting sports with a 5dll for years, and everyday before I go out, I knell down before the God of sports and have my wife hit me as hard as she can on the head with a 2x4. WHOP!! It's so I can remind myself that my 1 in 10 keeper ratio is not ALL my fault!!
R, are you getting my drift! :lol: :lol: :lol:

Can someone explain to me the effect of f-stop on auto-focus capability? If you get to a certain f-stop (like above f8) does your autofocus not work fully? I heard a review that said the 7D MKII "even does f8 AF"

auto focus is done with the lens wide open in most cases, then it steps down and activates the shutter. It takes a certain amount of light to auto focus so this means that if you have a lens combination that won't open to the body's auto focus limit it won't work. The specs for the 7D II say it will work at f8.

The AF system requires light to focus. The higher the f number the less light, but I always thought that focusing took place while the lens was wide open. Perhaps I am wrong about that.

So does that mean if I'm taking a picture at f11 or higher, for example a landscape, I need to manual focus?

canonrumors has some comparison shots between 7D and 7D MKII at ISO 3200 - the difference is very obvious!

No, the auto focus is done with the lens wide open, whatever that is for that lens, say f4 on my 24-105 f4, then the lens shuts down to the metered (or preset) f stop and the shutter activates. (it happens fast, all you hear is the mirror slap)

No Basil, we are talking about native f-stop within the lens itself, not that set in the camera.
If your lens is natively an f5.6 as in a 100-400 at 400 , most all cameras will AF.
But when you put on a 1.4x, the lens drops a stop to an f8 and the cameras focus system is not sensitive enough to readily read the contrast to focus, so it won't focus.
Pro cameras mostly have the sensitivity needed to focus, but consumer cameras do not. ;-)
The ability to focus with an Extender added to the lens is why its such a big deal.

Thanks robertjerl and SharpShooter. I think I understand. So the 7D MKII will work at f8, correct? (Meaning with a 5.6 and 1.4 extender?)

Yep!!!
