To make the story short, my wife and I started a photography business for candid portraits and journalistic style weddings almost six months ago and are seeing enough business and opportunity to take the plunge on a big purchase to upgrade our equipment.
I currently shoot with a 50D and she has a T3 and we have stretched these cameras to their limits.
We are potentially buying two cameras. The first will be a 5DmkIII without question, but the possibility of buying a second is still in the air. If we are going to take the plunge from a business perspective I'd like to buy two 5D3s, but that's out of our budget coupled with the lenses we need to upgrade.
We could probably get by with the 5D3/50D/T3 as backup but I don't trust the T3 to compete with anything once a light is turned off. It barely squeaks by at ISO800, and that is unacceptable to me if we should need it.
What would you all suggest as the second camera? The 6D is outside of budget and close enough in price to the 5D3 from an investment perspective that we'd just get two if we could swing it, but we can't. So that leaves the the 7D and 5dmkII.
For those of you that have used these cameras at weddings and other candid events, what would you say the highest acceptable ISO is when shooting RAW? What about AF performance at f/2.0 and below in okay to worse light?
I know full-frame is the best option for portraits, but the 7D is pretty cheap brand new right now, so I don't want to take it off the table.
Thank you once again CR
