Another thing to consider is getting the shot in the first place. My brother is freaky about IQ to a fault. His ideal camera would some sort of industrial camera which needs to be tethered to a computer and uses three shots and interchangeable color filters and then stick the pics together in order to get the best color accuracy possible and fine detail ect.

But what for? He is just an amateur photographer like me, I don't need 400 MP. What am I going to be taking a pic of? My cat? Down the street? A backyard bird? Until I start putting ridiculous amounts of effort into taking a shot of that level would I dream of such a setup.

I am much more interested in making a picture that wows you, learn to take an amazing pic to begin with. Obviously I want the highest IQ possible for my budget but being a birder getting that shot is first and foremost and IQ second.

Just my rambling thoughts.
