Hi,

I want to thank Don and Isaac for the help about the BR-3 and BR-6 operating 
differences.
Now it makes sense with what I understand to be the Nikon AI mount. So the BR-6 allows 
one to focus and compose with more light. To meter with the BR-6 does one have to 
press slightly the AR4/7/10 cable release so the lens is stop down?

Based in your experience does the BR-6 extra money pay for simpler and more convenient 
usage?
