I recently won a Hexanon 28 on eBay, which I've tried out and seems to work great. But just today I noticed that the front-most ring of the lens -- with the red dot showing what aperture has been selected -- can be rotated on my lens. In fact, when I screw on the hood, it rotates until the hood is screwed on all the way. Is that normal? Seems to defeat the purpose of the red dot, which I would assume should be stationary, no? I'm inclined to keep the lens anyway, unless someone here tells me this is a possible sign of something seriously wrong.
