comment What is the real world impact of the lossy compression used for NEF RAW files in some Nikon cameras?
Yes, the 16-bit TIFF can store more information than the 8-bit JPEG, but what it doesn't contain is all of the information from the NEF. The white point, black point, color temperature, brightness, etc.are "baked in" at conversion.

I edited the answer by expanding the last paragraph and moving it to the beginning of the answer.

@NeilL Your first comment contains an incorrect assumption: an NEF file does not contain more (visual) detail than a JPEG file. It contains more information that can be used to alter the color, contrast, exposure, etc. of the image without degradation the way altering a JPEG to the same extent would.

@mattdm I feel the last paragraph specifically addresses it. If you are not going to do any RAW editing, then it makes no practical difference.

8-bit and 16-bit TIFFs have the capacity to contain more information than a JPEG. Depending on the source data and compression, an 8-bit or even 16-bit TIFF could actually still contain less information than a JPEG. But you are correct that in normal usage a 16-bit TIFF converted from an NEF file would contain more information than an 8-bit JPEG.

comment 5D Autofocus - disable tracking after lock?
Basically, all the autofocus zones per lens guide does is tell you that the camera automatically turns off focus points that require a wider aperture than the maximum aperture of the lens connected to the camera. If you are using an f/4 lens, none of the AF points that require an f/2.8 lens will be active.

comment How do I create emphasis with a single color in a B&W image?
It's called selective color.

It depends on the way the TIFF file is made: You can make a 16-bit TIFF but you could also make a 4-bit TIFF and 8-bit TIFFs are fairly common. JPEGS are by definition 8-bits per channel.

@NeilL It depends on the way you save the TIFF: 8-bit or 16-but? Lossless compression, uncompressed, or as a container for a previously compressed JPEG? There is a wide variety of ways to create a TIFF file that determine if an how much it is compressed and how much info it contains. See en.wikipedia.org/wiki/Tagged_Image_File_Format
