Hi,

I'm interested to buy a NN3, and I'm trying to find out if a Canon EOS 7D with EF-S 15-85 can be used on the NN3.

I've found the distance A and B (definition according to the image of http://www.nodalninja.com/support/camerasettings.html) for this kit, so my questions are :
- what is the biggest value that can be set on the lower rail of the NN3 (distance A) ?
- what is the biggest value that can be set on the upper rail of the NN3 (distance B) with an arca style quick release (ASQRC-2) ?
- is it correct that the ASQRC-2 + plate add 13mm to the distance A compared to CP-1/CP-2 ?

I assume that the ASQRC-2 can be mounted vertically (to insert the camera vertically ; for a RRS or Acratech camera plate). This isn't a problem for the clamp lever, right?

I'm aware that I should better use a NN5 for this camera, but I can't afford the weight difference on multi-days hikes... Would the use of the NN3 pose a serious problem?

Thanks in advance for your answers,

Stephane
