Lens Release
 

I've noticed my Lens Release button doesn't go all the way up when it's supposed to be locked. The lens lever rotates and lens can be removed regardless of the position...how is this supposed to work?

Thanks

That's the way it is. Not the best bit of design.

Thanks Alister..that's good to know.

I keep forgetting it's even there!

You'll sure know it's there when it works itself loose. I had the lens come off in my hand once--luckily my palm was wrapped around it. It really should lock.
