So I hadn't planned on getting the R5, I am still happy with my 5D IV however... CPW had a deal last night on the R5 at $3699 from a US authorized Canon dealer with no tax and free shipping so I pulled the trigger. My question is this, When I look through the EVF on the R5 with a polarizer and LEE ND filter(s) attached will I see the differences as I rotate and move the filter(s) the same as I do using live view with a loupe against the LCD on my 5D IV? Also, what loupe do any of you recommendI on the R5? Thanks in advance.
