I'm new to digital SLR camera..
My brother has a Tokina 20 to 35mm F2.8 lens for his analogue camera Nikon F601.
If I were to use this len on Nikon D80, does that means I have to multipy the focal length by 1.5?
Likewise if I use "AF-S VR 18-200mm f/3.5-5.6G IF-ED DX" on F601, I should divide the focal lenght by 1.5? Is that correct?
Thks in advance for the reply...
