Please correct me if I'm wrong. My understanding is that if I mount a 100 mm DX lens on my DX camera (D7200) it will give me an angle of view equal to that of a 150mm lens because of the 1.5 crop factor. My question is this. If I now mount a 100mm FX lens on the same DX camera, will I still get a 150mm angle of view? In other words, does the dx/fx designation on a lens make a difference in the angle of view or is it just the size of the sensor that controls this. I'm sorry if this has already been answered but I couldn't find it in the search. Thank you in advance of your answer/answers

Years ago I met a gentleman at Yosemite at the Tunnel View. I don't recall what I had, probably a Leica or a Nikon but he had some sort of well designed contraption for lack of a better word that used a small camera that was positioned to take single exposures of tiny parts of the scene. I THINK he needed to manually take one picture and then the next for up to around 20 photos. At a later date he would merge all of the 20 pictures for one ultra sharp photograph. Not to over explain but basically he filled in 1/20th of the scene with each photograph. He told me he went around the country to take these photos that were ultra sharp and then sold them to companies.

This was maybe 15 years ago or more. I relate the story hoping that someone else would recall such a person/camera usage and fill in some blanks to go along with the posting by the OP.
