I'm not a sound technician or audio expert. I do have some knowledge of them. I am looking for a field audio multi-track recorder and came across these two Zoom products - the Zoom F8 and the Zoom R16. I know that the Zoom F8 is the recommended field recorder for video production work. For 1/3 its price, the Zoom R16 can pretty much do the same. So what's the difference where Zoom markets the F8 for video work while the R16 as a Desktop DAW interface? Why shouldn't I chose the Zoom R16?
