Noise with the Sigma 10-20 on a D600
Just got a D600 with a couple of FX lenses (Nikon 28-300 and Tamron 24-70), but for now I was planning to use my old Sigma 10-20 DX lens until sometime next year. I know the limitations of DX lenses on FX cameras, but it seems to me that noise, which isn't very apparent on my new FX lenses, is very prominent on the Sigma when the ISO is set above 1600. Should that be the case?
Guess I'll be shopping for a WA zoom sooner than I expected!
