Ok, so this is really nitpicking, but . . . I went outside a little while ago in
the late afternoon of this sunny day here in the northeastern U.S., far enough
north that the �sunny 16� rule is more like sunny 11 for much of the year (but
not as far north as you folks in Canada, the UK, Oslo, etc.), and with an ISO of
100, an f/stop of f/16, and a B+W circular polarizer, I got a shutter speed of
1/30 sec. to 1/45 sec., depending on framing, and exluding the sky from the
scene. I don't think I go to anyplace unusual to photograph, but at those speeds
I can usually find something to brace against or on�a tree, a rock, a
knee�especially when shooting landscapes, particularly with a wide-angle lens.
For landscapes with a telephoto, I probably wouldn't ever go to f/16�I try not
to go past f/11 most of the time anyway, since I prefer the in-focus elements to
be sharp, and will always trade some illusory sharpness in the far distance for
maximum sharpness in the parts that really count. As presumably we all know, as
you get into smaller f/stops sharpness falls off due to defraction effects; with
most lenses maximum sharpness falls somewhere within the range from f/5.6 to
f/11, depending on the design.
