Reading this thread has made me reach for the anti-anxiolytics: I had no idea that so many members on the forum tote firearms as well as cameras and expensive glass
Henceforth, my posts, especially in response to requests for C&C, are going to be considerably more circumspect and respectful
Any forum member know where I can get kevlar body armour for a good price

It seems you have a left master eye, if you point at an object with both eyes open, then close one eye at a time, whichever eye sees you still pointing at the object is your master eye.

Hi John. Found this link on the back of what you said.

So, I'm unusually right handed, but left eyed

"Just had a talk with Pentax Europe's former technical service manager,
now 645D service (they will keep that in house) and I learned the
following:
- SDM failure rates are monitored and do not exceed those of other components,
- Pentax is aware of the buzz about the issue but considers it unjustified,
- not every perceived failure necessarily is one. SDM motors hold a
charge which depletes after prolonged (months) non-use. Once
discharged, the lens will no longer focus. The charge takes up to two
minutes to rebuild, i.e. the lens needs to be left alone for that time
while connected to a powered on camera. At times, that may still not
be enough to initially overcome mechanical stiction from the long
sitting period."
