Or: the same people who came up with 1,024,000 bytes
per Megabyte (or
"35mm equivalent" for focal lengths of lenses on digital cameras) could
Oh don;t get me startedon that one. It's one of my pet hates. The focal
length fo a lens as a simple, optical, maining. And the real value should
be quoted, not some 'corrected' value.
Around I'v got cameras for a number of film sizes from sub-miniature to
medium format. Every one of the lenses, if it's marked at all, is marked
with the real focal length. So yes, the 'standard' lens might well be
24mm, 30mm, 35mm, 50 mm, 75mm or 80mm. Thsi does not confuse me...
Oh, and the next person who claims that changing the focal length affects
perspective is likely ot end up being shown another use for an MPP
monorail :-)
easily insist on measuring to the first track AFTER
the DIRectory ("system
overhead doesn't count")
Therefore, it is certainly not past the current behaviors of certain
clueless lusers to call it (8") a "3.5 inch radius" disk :-)
Would you get 6" width of a 5.25" drive if you included the AT mounting
rails?
It;s going to be getting towards 6", I think, but the only AT I have set
up here is the one I am typing this on, and I don;'t feel like
dismantling it to check.
