Agreed, its essentially useless for what I want to do. Way too wide a 
field of view. I need an endoscope sized camera with a long lens and a 
very narrow F.O.V. for mounting on a milling machine head for a video 
edge finder. For this app, it needs focusing, or at least mechanically 
adjustable to something in the 50mm range as it must be mounted high 
enough to clear fixture bolts holding down the work. Cameras which 
encounter those bolts are destroyed like so much velveta cheese

We have software, capable of rotating our co-ordinate systems to make a 
mounted part which may not be mounted in perfect x/y alignment into 
perfection for the milling machine but it needs tlc, in that if the 
image is expanded until the cameras image touches the edge of the 
allocated window, the image goes away and the computer must be rebooted 
to restore its function.  Since that occurs as the LinuxCNC "axis" 
control window is expanded and before it reaches full screen, its a 
right pain in the ass to try and use.

Does a review, with an eye toward this kind of use exist?

These are nice, but these cameras are huge and unusable because of their
