I know this sounds like a stuiped question but I have got to ask. The nikon D-300 has a 1.5 crop factor.Now is that only with a DX lens. Do you get the same 1.5 with an FX lens on a D-300. To appreciate the additional mm lens on a D-300 does it have to be a DX lens. Is using a FX lens on a D-300 basically the same mm as an FX lens on a full frame camera? I have mostly FX lenses only one DX lens. My D-300 is in for repairs and I am not sure if its cost effective to repair it. I am debating on getting a D-300s but I have a D-700 and considering using that. I only have one DX lens but I have a D-700 for my FX lenses. I like to photograph wildlife.Any help is always appreciated
