f-stop question

My understanding is that a medium format film camera has no problems with f22. It is the size of the hole that matters isn't it, not the f stop?

8X10 format cameras can go all the way to f/64. As long as you're contact printing no one is going to notice any amount of diffraction, not with negatives that big. Contact printing a 35mm negative isn't going to impress anyone.

Not true anymore. Microbrew is the new trend and these are as often as not very high alcohol content. The days of 3.2% beer are long long gone.

I think we're way behind the States in microbrewery development.

As consumers, we put up with the 5% mainstream lagers for too long.

Thank Providence for that ! The weak stuff is like making love in a canoe.

Good question. When I check the box that says 'Set circles of confusion based on pixels' and throw in 36 megapixels, the calculator suggests diffraction starts at f/11.

This is why I asked.
