Why would I buy the same three year old camera I already own instead of new technology that will make my job easier every day? and "pay my rent" is a phrase that means "work". Can you do your job without a computer - or if your a ditch digger a shovel? If your a painter you don't buy garbage brushes. Get a clue hobbyist.For the $4000 you're spending on an unavailable camera you could buy a 5D4 AND a 6D2 brand new.
For a 'professional' that can't pay his rent it seems like the R5 is a 'want' and not a 'need.'
