For shutter speeds, you're top-of-the-line 35mm bodies will have up to 
1/8000 s shutters at the high end, and "bulb" (arbitrary, user 
controlled) at the slow end. I don't know if the camera records the time 
when it's in "bulb" or not....

jus' sec...

Okay... in "bulb," my 10D reports exposures 1 sec and longer in nice, 
round numbers.... I don't know what it will do with exposures over 30 
seconds. If I find out something along the way, I'll let you know.

Future cameras will likely have shutter speeds shorter than 1/8000 s as 
the technology creeps forward.

Focal length will, effectively, be "random." Your zoom lenses can be any 
length between the minimum and maximum. On the point-n-shoots, you're 
looking at lengths as low as ~3mm, up to the monster 35mm lenses at 
1200mm, and possibly longer....
