I cannot take a picture on any setting or mode or in any lighting and with any lens that doesn’t turn out noisey/grainy. I want to sell and upgrade to the new R6 Mark ll coming out..hopefully it won’t look so bad. Any ideas on why so much grainy low quality images?
" Any ideas on why so much grainy low quality images?"
Your ISO is too high, I.E. a big number like 6400 or 12,800, etc. Although the newer R6 line will have a better high ISO performance at some point it also will show grainy photos at some point. There are limits to all cameras.
