So, in a fine and long-standing tradition of Murphy's Law in action, I'm having problems with my D300s and my 70-200mm lens.
The problem is this: When I mount the lens to the camera, and it locks in place like all lenses do, it doesn't lock 100% tight.
By that I mean there's a slight rotational free play between lens and mount, and it's just enough to throw the CPU contacts out of whack, and (what I'm guessing is) short out the camera's ability to interact with the lens.
The problem can be triggered by hand-holding the camera and lens, and applying slight torsion, like is possible when focusing or zooming the lens, or even when raising and lowering the camera to shoot.
I should point out that I've been relatively careful with both camera and lens since day one - I appreciate it's a heavy lens and damage could occur if the lens and body aren't properly supported.
Anyway, I have an email in to Nikon to see what my course of action should be, but I was wondering if anyone else ever had a similar problem and could shed some light on how it was fixed.
Some other miscellaneous points:
- everything works perfectly if the torsion does not occur (small victory)
- problem can be solved by turning the camera off, re-seating the lens, and turning it back on
- sometimes if I don't realize it's happened, I can take photos thinking everything is fine and the pics are black (no image) - obviously, this is the worst part.
- all my other lenses do not have this problem (so I'm hoping it will be the lens that needs fixed, and not the body, because I don't have a back-up and Nikon is taking their sweet time with the d800 ;) )
Thanks in advance,
