I don't want to over use this photograph, but it's the best example I have to illustrate my question.
#1 is what the apc-c sensor yields.
If I want to print an 8 x 10, or let a lab print it, here's approximately what will come from the original.
So, to get the 8 x 10 print, not all of what was on what the sensor (Film in the old days) will fit.
So, my thought here is....
If all you ever intend to do is present your photos digitally, then you can simply fill up the VF knowing that it will all be displayed.
If you intend to produce 8 x 10 or 4 x 6 prints, I think you have to keep that in mind and leave room for the inevitable print crop.
Now I now that the 95% view in the VF does some of this, but I would think that you would have to keep it in mind.
BTW, I did slides as well but coverted a lot of them to prints.
