Specifically, I am interested in which configuration for which camera. I have a D3s and D7000, so would the smaller configuration be usable with the D3s, or will a new set of lower and upper arms be required to accommodate the D3s?
Obviously the main goal is the overall cost of having to support both cameras, whether to start small but add modular pieces to support the D3s later, or just go with the larger configuration from the word go, etc.
Any information or recommendation for the combination of the modular pieces with the two cameras mention above would be very much appreciated. Also, some idea of the cost for the various pieces (longer lower/upper arm, etc.) would be very useful as well. Thanks.
