Viewfinders - Inon 45 versus Sea & Sea 45

07 March 2013 - 10:21 AM

Can anyone tell me if there is any significant difference between these two viewfinders. I currently use the Inon but have never seen the Sea & Sea version. At first glance they look the same unit, but from product photos they are clearly made  differently. 

 

Importantly, does one have a bigger and better view than the other?


Advice needed on understanding wiring on a Sea & Sea housing

Here we have the inside of a Sea & Sea DX-D80 housing showing the wiring from the 2 Nikonos bulkheads. The wires join at a small board before going to the camera hot shoe connector. There are 5 wires from the TTL converter bulkhead and 2 from the other one. Any idea how the wiring works and what the components are and why they are there. Would I be right in thinking that they might be diodes. Is this a standard configuration when two strobes are wired together electrically?
Any insight would be helpful.

Nauticam 45 viewfinder. What does the dioptre adjustment knob do?

07 October 2012 - 12:42 AM

This might be an odd question, but can anyone tell me what the dioptre adjustment knob actually does? Is there a particular eyesight problem that this can help with? Would it be an alternative to a presciption mask for example?
