I have all of my EOS equipment listed with Canon.  I have purchased a 90D and Canon will not accept the SN to register my kit.  If and when I do want to have service in the USA who is trustworthy?  I live in NY.  
I'am confused about how to find shutter count.  On my 90D under Battery info a shutter count number comes up.  It is 35.   Now if I pick a jpeg I'am told the last for digits ( when you press info) it says 5393!  Can one explain.
