Dear Berg Na,

Did you really check it using D100 with lens faster than f/2.0? If you set apperture f/2.8 or greater, this kind of phenomenon does not happen. I know what M mode means and I know shutter speed setting and aperture setting are independent to each other. But here in Korea, when I reported this phenomenon on a website, almost everyone who tested the same combination got the same result. Shutter is closed only after 15seconds.

This is a question to whom are using Nikon D100 and lens faster

than f/2.0 such as AF50mm f/1.4D. Please try the following

combination.

Set at M mode,

Set apperture at 1.4, 1.8, or 2.0,

Set shutter speed at 30 seconds.

Please measure the actual shutter speed. Mine is closing the

shutter after only 15 seconds. What about yours?
