The point is: if it synchs properly now at 1/250th, it is likely to synch

properly at 1/250th for the user's lifetime of "normal" use - but if not,

the user can then use a lower synch speed as the camera ages (though

this is unlikely needed...). Also, the FA was built with the same shutter

and the 1/250th synch speed, and it was a "higher-end" model. Or,

who cares if the Buick won't go 250,000 trouble-free miles if you will

never drive it more than 20,000 miles and it would likely go another

100,000 miles after that...?;-)
