50-135mm focus ring

Hi,

I was wondering if it is normal for the focus ring to go beyond the focus scale (both ends).

If I wanted to, I can actually turn the ring 360 deg. Is this normal?

Having said that, the ring is not loose in anyway. There is a "thud" sound as you reach the limits but you can keep on turning.

Thanks...

I dunno. Sounds like the thing is busted. I'll give ya $40 for it.

You are of course talking about the Pentax DA* 50-135mm and it's clutch like feature in the focus ring. That is it's intended design.
