Day One, What is a Nikonos

Nikonos is a series of underwater cameras,  Started in 1963 with the Nikons or Calypso Camera, Nikonos II, Nikonos III, Nikonos IV-a, and ending in 1984 with the Nikonos V.

 

Nikonos I, II, & III are fully manual and require a separate Light meter, be it the specially designed Sekonic in its separate housing or my favorite the iPhone app myLIGHTMETER where i set my exposure prior to shooting and go with it.  

 

Nikonos IV-a & Nikonos V have built in light meters where they can shoot aperture Priority or Manual (Nikonos V only) 

 

 

 

 

Day Two, These camera's are as old as some of your parents.
