I just received my first AP setup (ES80mm FCD100 & EQ6-R Pro). I own both a D5100 and a D7100 and could use either but I know that the D7100 has a Toshiba sensor which can cause some less-than-perfect results in AP. The sensor on the D5100 is Sony I believe. Just looking at it, I think that the 5100 would probably perform better but would require an additional cable to be able to run on BYN. This additional cable would take me past the number of usb ports on my laptop and require me to figure out a 12v d/c USB hub (that's for another thread).
I guess my question is: will the d5100 provide better enough shots to justify the extra hassle of the additional cable and setting up of a usb hub?
I would love to hear any thoughts.
