One thing to keep in mind when purchasing camera equipment is depreciation. Whatever you buy today will be worth less tomorrow. If you buy a body new, especially an expensive one the value will depreciate. When Canon 5Diii’s were selling for $3499 I bought one for $2800 refurbished. I thought I got a great deal. Two years later even before the 5Div was released I sold it for $1900. I didn’t even use it since I owned a 70D and 6D at the time. Did I get $900 of use out of it? Nope. Using the 5Diii I learned that it was way more camera than I needed. The AF options were intimidating. I was much happier with my 6D for landscapes and 70D for action and telephoto shots.
Whatever camera you want to buy, compare the used and new price. You might be better off buying a used one.
Since the body of an M3 is $479, M6 $779, M5 $979 a buyer won’t lose more than $200-$300 on a sale of a 2-5 year old body from the new price. A great deal!
