I am not at all familiar with tilt shift and do not understand the concept. I see that there are lens dedicated to this function. Also, software that can preform this function. I have looked at photos that are reputed to be tilt shift and see no difference of any other photos except they all seem to be shot from an elevated position. I would appreciate any explanation in layman terms. Thanks - Bill

One more lens question is there any advantage to using a FX lens on a DX type body

Thanks for the info it clears up an a point I needed clarified.

After shooting film for years I weaken and am switching to digital. So, now I have a question. I am shooting with a Nikon D5500 and my question has to do with the lens - I understand the 1.5 factor but what I don't know is if the lens is a DX does the factor apply Example 35mm DX compared to non DX 35mm
