Hi right now I have a 5D III with L lenses and I am looking for a back up camera (just in case) like when I am doing a wedding or baptism but that is once in a while, I do not need to pay for a 6D just to have it in the bag, so right now my choices are, I found a used 40D with battery grip and 2 batteries and he also has had the shutter replaced a few months ago and he is selling it for 350.00 euro, and the next option is I found a 7D battery grip and 2 batteries with 30.000 clicks and he is selling it for 800.00 euro, I am tempted to buy the 40D but is the 7D worth the extra cost to the 40D? thanks.
