Question #1
I've been lurking about for a few weeks now and it is time I tapped into the wealth of experienced knowledge here at nikonians.

Bought a new D700 with a couple of new lenses. The AF-S 24-120mm fits nice and snug in the mount to the camera with little movement, hard to detect unless I really go looking for it. The AF-S 70-200mm is another story.

The best way to describe it is I have a Nikon hand strap, AH-4?. If I fit my hand into the strap and secure my grip with the hand strap, drop the camera to my side and start walking I feel a jiggle in the camera.

Grabbing the camera body and the lens with both hands individually and give a twist back and forth, I have approx. 3mm play/slap.

Is this acceptable in a new camera and lens? I always feel it jiggling and it is bugging me.

Question #2
I have a dot in my shots. I'm new to the digital world so I would like to find out where this is coming from or where to check. You can see the dot, which is a bit faint in this picture.

It's a 1/2" left of center, about a 1/4" down from the top of the shot.

I cleaned my lenses next to a sunny window. Lens glass on both lenses was clear but the neutrals needed a bit of dusting and a smudge on one filter needed to be worked out. Shot into a blue sky with both lenses and both shots had the dot. Removed the lens and looked at the mirror. Saw a fleck of dust and removed it. MUP'ed and I could see nothing on the sensor with a cursory look. With a better look at the sensor, will I find the dot creating culprit or is it a pixel problem?

If sensor cleaning is all that is needed, is there a good tutorial on cleaning a sensor somewhere around here? I don't want to screw something up as I'm a bit nervous playing behind the mount area.
