D300 & Tokina 12-24 problem
I have a Tokina F4 12-24mm wide angle lens that won't always allow me to set the F stop while in manual mode, it usually locks at about F16, varies sometimes but won't let me get to F4 or F5.6 . Than at other times it works perfectly. In other modes it works fine, no problems.
Any one else have this problem, not sure if it's the camera or the lens.
