- the 7d, with its higher pixel density, requires good optics to get very sharp 100% crops, so lenses that may work great on the 5d2 may not be the sharpest on the 7d

Just to clairfy this point. If you're not looking at the individual pixels, but at full-size images, then a lens with not-so-good optics will not perform worse with a 7D than with a 5D.

I had the 40D, then the 7D, then the 5Dii. I was at a fashion show and was using the 5Dii and the venue was so dim that the focus wouldn't lock. I switched to the 7D and took hundreds of keepers. Sold the 5Dii, bought the 5Diii, am very pleased. Low-light /high ISO capabilities are useless without getting focus to begin with. My $0.02

Interesting conversation here - but just another note to a few of you who missed my update, I did decide to just ADD a used 7D and keep the 5DII. I was more comfortable with spending that amount than than upgrading to the 5DIII, especially when the value of the 5DIII will probably drop faster over the next couple years than my older cameras.

Now, my issue wasn't that I could NEVER lock focus with the 5DII in low light or with movement, it just wasnt consistent enough for my liking. So, I agree - the 5DII CAN do it - just not every time. After a week or so of using the 7D here is what I've found - and probably not many surprises here:

-Outdoor moving subjects: The 7D with any AF point is generally more reliable than the 5DII is with the center point - although the 5DII center point is still decent. The 5DII outer points don't seem terribly reliable in comparison but can be used if you're willing to accept a lower ratio of keepers.

-For outdoor stills, the 5DII center point is about as accurate as any of the 7D AF points. The 5DII outer AF points lag behind but are still useable.

-Indoors and low light with still subjects, the 5DII fares better with the center AF point than any AF point on the 7D, but the 5DII outer points are very poor. All of the 7D's AF points seem to only slightly lag behind the 5DII center point.

-Neither camera is extremely good with moving subjects indoors but I can manage some keepers with both using center point.

All in all, I'm satisfied with the purchase as the 7D opens up some new opportunities for me but I don't think it necessarily solves my problem. But, between the two bodies I'll be set well enough that I can leverage the strengths of each under suitable circumstances and continue to use workarounds like prefocusing, flash focus assist, etc when conditions are less favorable.

Same glass on both bodies? In my AF tests that I ran very extensively due to the issues I was having with a 1D4, I found that the 7D and 5D2 performed very, very similarly with center point in low light. The lens selected though, made a big difference, some sigmas wouldn't lock, but a Canon usm L would, for example.

Which AF mode were you using on the 7D? In low light moving targets, I found that the center point with expansion did a very good job with the 24-70L.

That's just the mode I used. Like I mentioned in the beginning - we're talking 1/80, ISO 3200, f2.8 in a small(ish) room and young kids. I don't think I can expect perfection in those conditions. Even the 5DIII missed some, it just did better.

I usually don't have a problem with those settings, my equipment would start to give grief about 1-2 stops less than that. The 1D3 was amazing with what it could lock in with, and now with the 5D3, it is crazy how dark it can be and it still locks. :)

yes, 24-105L, but I may have used an outer focus point due to portrait orientation, methinks?

Could just come down to technique then...this landscape shooter is used to ISO 100, f16 and a tripod at 4am, not focusing on movement at iso 3200 and f2.8. The 5diii might have just done a better job hiding my poor tech pique at this new type of photography.

I'm just curious, if you're out for vacation and don't want to bring 2 cameras, which one will you take? 5d or 7d?

1/80 is awe fully slow shutter for moving kids, that might be your issue.

I try to catch them in the brief moments of inactivity in these conditions...trouble is, AF still has to keep up because the moment is there and gone.

Depends on the vacation...bird hunting trips I'll bring the 7d for the AF and reach. "Up north" I'd bring the 5d since I'm a landscape shooter and that's my kind of country. If I didn't really know what I was going to get into or more casual/general outings, I'd probably bring the 7d.

I always raise my ISO to 6400 when shooting the kids milling around inside. This helps a bit on the shutter side of things.
