I don't yet own a D7100, I almost ordered a refurb D7000 from Adorama and then Nikon announced the D7100 so I'm waiting for the new camera since it'll be used mostly for nature photography and situations where I need high iso's. What is the buffer limit between the D7000 and D7100? Due you find it limiting? My D300s and D700 buffer seems endless when using jpg large. I occasionaly reach the limit when using nef but that doesn't happen very often. I'm choosing the D7100 because I don't think there will be a D400. My income tax refund is due back next month or early April. If there isn't a D400 by then, I'll order the D7100 as Nikon's top of the line DX body.
