Seems that I have made a mistake. This is not the first time - I made another one in 1959...
I listed a cashback offer from Olympus regarding an 8mm Olympus lens and thought that it was a f:2.8 lens. Wrong.
Daniel Morton has just corrected me - it is apparently a 1.8 lens - which means the fish can see in just half the light...A decided advantage for all of us.
Thank you Daniel and thank you Olympus.
