To quote a famous quotation: you can not be serious!
Rob C
I am entirely serious. Perhaps I mean something other than you suppose. I used to own a 40D and a 5D Mkii myself and of course was aware of the difference between their viewfinders, particularly immediately after I first acquired the 5D. But after a while I became less aware of it, and took each camera as I found it. And when I picked up either camera, I simply used its viewfinder to look through and rarely reflected on its quallity, whether positive or negative, because it was a given as far as my current image was concerned and noticing it could only be a distraction which, if the subject was fast moving, might even result in my missing the shot. I am not saying that an excellent viewfinder isn't a fine thing and generally conducive to image quality - that would not be a serious proposition - rather that when taking a particular photograph with a given camera, it is only the variables that can have an
immediate impact so that thinking about anything else is a waste of time. My general point was about the importance of concentration in photography, as opposed to - or in addition - to observational powers, however defined, and about the nature of concentration, as requiring that we notice only what is immediately relevant. In the video referenced by Slobodan, anyone who notices the monkey necessarily fails at the assigned task - counting the number of times a player in white passes the ball. In photography, think about the quality of equipment before you buy it rather than while you are using it.
