Does anyone know at what length in mm a lens is considered a "long lens?"

Just guessing I'd say anything over 200mm.

i would vote for 400mm and up as long.

The specific mm would vary depending on the camera format used.
Wikipedia says it's a lens that's longer than the diagonal measurement of the film or sensor for a particular format.

I'd say a factor of two in focal length.
On a FF camera (or an old 35mm camera) my definition would be longer than 100mm. 50mm is generally considered "normal" for that frame so twice that would be long. On my old speed graphic, the normal lens was something like 150mm. It really wasn't set up to take longer lenses easily (or shorter, for that matter).
If anything below 25mm on a FF camera is considered an "ultrawide" lens, then anything above 200mm should be considered an "ultralong" lens.

The designations used to be wide, standard and telephoto. With Nikon, at least in film days, wide started at 35mm, tele at 85mm. There was also what they called Special Purpose, that included Zoom, Fisheye, Perspective Control, Guide Number, etc.

I always thought that size doesn't count. I know that's what every one is thinking- I finally said it---LOL

Telephoto does not have to do with lens length, it has to do with design. Yes, all telephoto lenses are long lenses but not all long lenses are telephotos. The reason for telephoto lens is compactness by needing less distance between the lens are the image plane than with a standard formula long lens. For instance the distance from image plane to the middle of a lens for a 300mm lens is 300mm but for a 300mm telephoto lens it would be far less than 300mm.

Point I was making -- straight from the old Nikon manual. Long lens is a pop phrase -- doesn't even appear in the Online Etymology Dictionary, so no hint of origin, not that it matters! :wink:

That sort of leaves the 1200mm, 1700mm, and 2000mm lenses out there as orphans.
