Dont want to offend anyone here, but guys, your are diving so deep i mena whats it all about? Two things:
Better you come back with an image which is not perfect because of diffraction whatever, instead of spending hours on this thread talking about something not really relevant for 99% of all users here...
Second, i shoot regularly at f/22 and similar low apertures and never noticed the mush youre talking about. I understand that we landscape or/and architecture photogs are going for the sharpest ever, but honestly, i dont care about that little sharpness loss caused by diffraction, as much as i dont care the sharpness loss wide open, because subjects and the image should choose the aperture, not the sharpness rating at each aperture.
just fyi, continuing the off topic'ness (cause i guess the camera ain't out yet so not much else to talk about).... i thought the same thing as you until i started doing focus stacking for landscapes. and this is the thread that started my dabbling in it:
the guy doing that pic says he focus stacks at f/5.6. for me that introduces the possibility of too much error (more images more possibility of me screwing something up), so i usually do f/8'ish. but anyway, i did it, and WOW, it makes a HUGE difference. we're talking mind-blowing sharp compared to my previous works at f/14-16. this probably also produces as good if not better results than using a tilt-shift (just guessing--i never used one).
here's an example of my own pic, but this one is at f/14 (my fingers were frozen and numb, my friend was waiting, and i just didn't want to make a mistake at bigger apertures), focus stacked 5 frames:
you can't tell from the pic, but the foreground rock is only about 1/2ft in width, believe it or not. those rocks are very small, but look big in the pic. but i was right at the minimum focus distance... like a 1/2ft from the rock. without focus stacking, there would be no hope of getting it all in focus, probably even at f/22. you can't see in that size, but i assure you that pic is razor sharp. using a 16-35 ii i might add!--i know people love dumping on that lens for unsharpness.
i would say that if you're buying an uber expensive lens like the new 11-24 or the 24-70 ii and then shooting at f/22, that's like buying a ferrari then rolling down a straight freeway at 60mph.
with all due respect of course
