Been debating whether or not to get the Canon 7D or just picking up the Canon 70D. I like the look and feel of the 7D much better, but is the 7D just too outdated to today's standards? To be honest the only thing keeping me from the Canon 70D is the plastic body. How is low light shooting with the 7D? I will be mainly using the 7D for shooting rock bands in low lit clubs and live houses. Will the Canon 7D be able to do this type of low light photography or would a full framed Nikon D610 be a better option (the other camera I am considering). Any and all input would be deeply appreciated. Thanks.
