I have never understood the debate.
I am finding that due to being a glasses wearer, that the image I am seeing and photographing with a 35mm lens really is more like a 40mm. I can not really see the frame lines for 35mm and 28mm on leicas.
When scanned and imported into my digital work flow, I straighten and crop to about the 40mm field of view. Sometimes, I can not get close enough and quick enough to take the image I see with my minds eye. So, I crop a bit more. Rarely but it happens.
In some people's eyes, this might make me not a good photographer. I really do not care about it. It's a hobby that gives me pleasure and my images are really for my consumption.
My perception is that most images plublished rarely fit the publishing medium and thus undergo some degree of cropping.
