Clarification on Video
March 24 (commentary)--It seems a lot of folk are confused about what the HDMI output of the D4 (and D800) is. The manuals aren't any help. The answer is a bit convoluted: it depends. If you take the cards out of the camera and use LiveView, you'll get uncompressed HDMI output (with audio) that matches the Movie Settings. No wrappers, no interpolation, but straight video matching what you selected. I hope you have a big storage device attached if you try that, as that's one heck of a lot of data coming down the pipe. Indeed, I'm not sure how I'd record that short of bringing a small and very fast RAID farm with me on a shoot. Even just testing this in my office I chewed through a lot of drive space.

The better choice is to use an Aja Ki Pro Mini or an Atomos Ninja and record the HDMI uncompressed output directly into 4:2:2 ProRes (Apple's native compression for Final Cut Pro X, and a very high quality compressor). But you'll have to press a lot of buttons and jump through a lot of procedural hoops to do that (which is what books like mine are for ;~), plus you'll have an HDMI cable between the camera and the recorder. Who's going to do that? Dedicated high end videographers who post grade their footage. If you're never going to go beyond Blu-Ray quality and don't do a lot of post grading, then just record to the cards and use the built in AVC compression.

This lens features a compact silent-wave motor for autofocus. This is pretty fast and quiet in most everyday situations, although not as refined as the SWM motors found in more expensive lenses such as the 18-200mm VR.

Nikon actually has 3 different kinds of AF-S focus motors in its lenses (that I know of).

They simply use the AF-S designation to differentiate these lense from the older screwdrive type that need a focus motor in-camera to drive the focus system.

The 18-55 and 55-200 KIT lenses actually use a MICRO motor. Not true AF-S at all. The give-away is the fact that they do NOT have instant MF overide. You need to throw a switch to manually focus them. The focus ring is attached to the std (micro) motor. Comaparing these lenses back to back with any of nikons other AF-S lenses you will notice they are slower and noisier.

The REAL AF-S lenses use either one or other of the other two REAL SWM lenses. These comprise of either a new lower cost ROD type used in the likes of the 18-105, 18-135 18-200 etc, and the RING type as used in the higher end pro stuff.

It is actually impossible to tell which kind of AF-S motors that any of these lenses have in them without pulling the lenses apart, as they are all quiet and fast.

Except of course in the case of the 18-55 and 55-200 (VR and non-VR) lense whaick have the micromotor.
