You have that backwards.
You can stop down to smaller apertures on larger format systems with the same effect from diffraction on your photograph that you would get at larger apertures on a smaller format. In other words, \"it hits\" later and is less noticeable at any compared aperture. You could shoot at f/32 on your 4x5 with fine results or smaller on 8x10, but don\'t try that on a 1\" sensor digital camera.
Think of it this way. For diffraction with measured diameter X, X is a smaller percentage of the frame size with larger formats, thus a particular measured absolute size of \"blur\" from diffraction has less effect with a larger sensor/film format.
Make sense?

Beg to differ. Don\'t care what anyone says. I lived it. Case closed
I shot MF digital backs for years it don\'t work like film. Once again a typical 35mm setup with great lens it\'s about F11. In MF with a full frame digital back and a great lens it\'s F8 when diffraction hits. Pixel pitch also plays a roll for sure. Why part of the complaint of MF is loss of DoF one reason is diffraction the other everything is bigger. I test this stuff let\'s not forget. I spent hundreds of thousands in MF digital. I know what wall I\'m hitting
I\'m stunned, and not sure how to respond.
You are wrong, and you can easily confirm that at the link I posted or any number of other sources printed or online. I also have shot and do shoot multiple formats ranging from medium format on down to tiny digital sensors, and I\'ve been doing it for decades.
That makes me also old enough to have had the experience — more than once — of discovering that something that I \"knew\" to be true (e.g. — \"case closed\") was dead wrong. Rather than being defensive or scared of admitting it, look at it as an opportunity to learn.
Perhaps I\'m so totally misunderstanding what you write that I have your statement backwards? I interpret it to mean that you assume that you can shoot at smaller apertures on cameras using smaller formats. For example, it sounds to me like you are suggesting that as we stop down we will encounter diffraction caused problems with the sharpness of our photographs sooner with large formats than with small formats,.
Is that not what you are saying?
The case is not \"closed\" because you say it is. Take this as an opportunity to continue your life\'s work of learning and improving.
