Angle of view is the same, at 220 degrees hemisphere	7.5mm F5.6 Fisheye-Nikkor  : 180 degrees hemisphere, produces a subject view of 23mm diameter circle in the frame. Six filters are built into the lens on a rotating turret, supplied with a finder (see below).

8mm F2.8 Fisheye-Nikkor Auto : The only one with an automatic diaphragm that coupled to the exposure meter. Allows TTL viewing without the mirror lock up. Meaning to say, perform like the modern full aperture exposure reading. 180 degrees angle of view, focus down to 1 foot, supplied with 5 filters on a rotating turret.

  

Anyway, all these lenses of yesterday have being discontinued. Why are they here then ? - you may ask. I think one should have a good knowledge and remember the origin of how our modern lenses began (like the current version shown below) . They are here because I was amazed and was never exposed to this info. I find it interesting and thought I could share something with all of you. Doesn't imply these are better lenses than the current version and hurry you to rush out to look for a set.

Something not that aged, availabled around the '70.
