Before I ask my question, I've read: http://www.luminous-landscape.com/tutorials/understanding-series/dslr-mag.shtml, http://www.digital-slr-guide.com/crop-factor.html and this http://digital-photography-school.com/crop-factor-explained I understand Nikon makes DX and FX lenses. DX's are for small sensor (crop factor 1.5) and FX's are for FF bodies. My question is, since the DX lenses will produce a smaller image circle, does it, then, have the crop factor? For example, the AF NIKKOR 50mm f/1.8D will produce a 35mm image circle, therefore, when I use it for my D80, I will get "75mm" instead. However, say, the AF-S DX Zoom-NIKKOR 18-135mm f/3.5-5.6G IF-ED , will produce a smaller image circle, do I get the 18-135mm view, or do I get 24-202.5mm? Sorry if my question was confusing. And thank you in advance. TN.
