Digital BW, The Print

FWIW, I just returned a Nikon 5K due to a problem with its' inability 
to disable the internal flash when a radio transmitter is attached to 
the hot shoe. The instruction booklet as well as Nikon tech support 
state that the internal flash is automatically disengaged when a 
flash accessory is attached to the hot shoe. This is not the case 
with the unit I purchased, nor could I get this feature to work on 
two other units I tried.Photographers who need to fire studio and 
location strobes BEWARE. 
Nikon tech told me they did not know IF or WHEN a firmware update 
would be created. But they did admit I was not the first to complain 
about this deficiency.
