Hi guys. This my first post so here goes!! I am fairly new to photography and am trying to get to grips with all technicalities. Three years ago I purchased a second hand Nikon D50, which I have been learning with. The camera itself is sufficient for what I need, but I have discovered I need a faster lens for taking photos of groups (I am currently using the kit lens Nikkor AF-S DX 18-55mm 3.5-5.6G). I would like to buy and 50mm prime lens and am looking at the Nikkor AF-S 50mm 1.8G. I notice that this is not a DX lens. My question is: Do I need to buy a DX lens?? I understand that the DX range gives smaller frame but I'm not sure if I can use a 'non-DX' lens on my camera?!? Any help would be greatly appreciated. Thank you :shrug:
