10/25   It was my impression that prime lenses have better contrast and
        details. But the MTF says otherwise. For example, 24-70mm has
        HIGHER number than 50mm.  Why is that?
        \_ It says, "The MTF chart for each lens is based on the value at the
           maximum aperture of the lens...."  50mm f/1.4 is two full stops
           faster.  That's 4x more light it can capture.  50mm lens stopped
           down to f/2.8 will likely give much better MTF chart, not that MTF
           chart is an end-all answer to everything.
           \_ That TOTALLY makes sense, thanks! Yes I have a 50mm f/1.4 but
              I don't have a 24-70mm to play with. I do notice that at f/1.4
              it is very very soft and unusable, but at 2.8, it is much much
              sharper (more color, more contrast, better details) than my
              18-200mm. The difference is huge. Thanks for shedding light
              on 4x more light! The forum's full of smart ppl   -dumb foto guy
        \_ how about just get a 50mm f/1.8 and try it.  Borrow from a friend
           or something.  If you can't tell the difference yourself, then,
           why bother with what MTF says?

10/26   The contingent of Yes on 8 people protesting on Lakeshore look
        suspiciously like people I've seen hanging around at the Mormon
        Temple up near Highway 13. Coincidence? Also, a lot of them
        have that urban overweight look to them, and their eyes look
        a little too close together. Hm.
        \_ Vader and his wingmen race through the Death Star trench.
           Biggs moves in to cover for Luke, but Vader gains on him.
           \_ This is not funny. Are you mildly retarded?
              \_ we're not going for funny here!
