I am soon going to be using the Nikon D800 DSLR (still on backorder) Looking at monitors/recorders. I really like the Atmos Ninja, since it can record 4:2:2 HD directly via HDMI out on the D800. It also has focus peaking. However, I have heard of problems not being able to use the viewfinder in direct sunlight. Is there any sort of 3-rd party eyepiece available for the ninja?
