Full Frame vs. APS-c
Is there a preference one over the other for taking photos of birds in the field. Does the APS's smaller sensor give more focal length for a given lens over the full frame camera. If it is true that you can gain a certain percentage of focal length for a lens with the smaller sensor, then would it be cheaper to buy an APC body over a more costly longer lens. I have a !Ds MII and want more focal length than 400mm from my 100-400 zoom. A teleconverter may drop me from autofocus to manual. An APS body may give me more focal length while retaining AF. What am I missing here?
