Here is a series of pictures I took this morning of an old flour mill roof in rural Quebec. The 645Z was tripod-mounted on a heavy Manfrotto 028. First picture was made @ 150 mm, 1/400 sec and f/11. The second one was made @ 220 mm, 1/320 sec and f/11. The third was made @ 300 mm, 1/250 sec and f/11. I made a comprehensive series of pictures using f/5.6, f/8, f/11 and f/16 at each of these focal lengths. In landscape photography, we have the luxury of time, so I never shoot any of my lenses wide-open. With use, I determine what the optimum aperture is and I set this aperture (usually f/11 on 645 lenses). In cinema, they determine the best aperture of the lenses they are using and set it permanently with a small screw so that the lenses are always providing the best images possible. I don't put screws but experience dictates what the optimum aperture is. Shooting a cedar shingle roof like this is pretty much the same as shooting a "proverbial" brick wall, only more interesting graphically. A lens has to be good to shine on a 50 Mpx sensor like the 645Z.

Pictures do not show for me. If I try to open them in a new window, it says

Sorry for the mess, I don't know what happened here, maybe the files are too heavy ...
