Oh, you're a master at understanding instruction manuals ... Of
course, your reading comprehension is obvious from your track record
in this thread so it's nothing new.
The legend "Exposure error may occur" in the chart means that if the
amount of light in the scene goes out of range of the camera's
ability to set an appropriate exposure time, the photo will be
overexposed. The maximum shutter speed attainable is 1/4000 second so
you're limited to a maximum EV value of {ISO 200 @ 1/4000 second @
whatever the wide open aperture is} ... for an f/2 lens, that would be .
You can set the lens' aperture to anything you want, but it won't
stop down in anything but Manual exposure mode. What this ultimately
means is that you have AE mode available for the tough low-light work
when you're shooting wide open and Manual exposure with semi-
automatic metering available for when the light is good and it's easy
to just guess the exposure if you know what you're doing.
Understanding what the manual means is just as important as knowing
the words, eh?
