It is true, that the difference between the SP500 and 1000 is the "lack" of
a 1/1000th shutter speed on the 500.  However, although the shutter speed
dial is only marked up to 1/500, there is a detente past the 1/500 speed,
where the 1/1000 speed should be, and the shutter does fire at that "phantom
speed".

It seems that when the marketing people came up with the concept of a
bargain Spotmatic without a timer, they decided that dropping the 1/1000
speed would be an incentive for some to spend the extra bucks for an SP with
both of those features.  However, the folks in engineering found that it
wouldn't be cost effective to design a new shutter without the 1/1000th
speed.  So, they simply stuck the old SP shutter in, dropped the 1/1000
marking from the dial, and didn't calibrate the 1/1000 speed at the factory.

So, the SP500 does have a "1/1000" shutter speed, although in fact, it
usually fires at around 1/750 or 1/800 - close enough to make it usable in
real life.

I have an SP500, and use the "phantom speed" when needed, with good results.

frank
