I want to buy a body I'll be using for the following scenarios and would like the thoughts and feedback of actual owners of these cameras.
1. Low Light - I want to shoot available light in dark environments (think churches, abandoned buildings, etc.) where the people might be active with decent depth of field. So I'm thinking f/4 - f/8, ISO 12800, 1/200. I want the best detail possible (hence the desire for a full frame).
2. Absolute razor sharp focus accuracy in good light/flash (ISO 100, f/1.8, 1/120). Not Live view or Manual, just standard auto-focus.
2. Ability to keep focus on moving objects that might shift away from the center focus point (BIF, football, car racing).
Budget-wise, the 60D seems the best choice, since it's available much cheaper. But it doesn't allow microfocus adjustments, which I would LIKE to have. The 7D has a reputation for great focus accuracy, but is older and I'm not sure how good the ISO 12,800 will compare to the 70D in real world situations. I have no idea how well any of these can focus in dim/dark environments (churches, etc.) with just available light.
Any thoughts? Experiences?
