I would like a bubble level that mounts on the hot shoe of my Nikon D850. Adorama has four different brands that are apparently universal mount. However I believe the newer digital cameras (Canon, Nikon, Sony, etc) use slightly different size hot shoes. Does anyone know if all of these aftermarket bubble levels will fit a Nikon hot shoe?
Why do you want a bubble?
I don't mean to be rude, but modern cameras are capable of great adaptability and complexity - I can't think of many easier things to do that use the level functions. Tell me, how do you get it level when the camera is to your eye? You can't see any bubble that is in the hot shoe then?
I bought a bubble level to use on my earlier cameras with two axis levelling built in - that wasn't good and none of my tripods have been right either and all of those methods are really slow and clunky to use.
I have a ball head on which the top plate rotates independently of the rotation of the whole head so I can throw my tripod down without worrying about level at all then set the level on the screen at the rear and shoot.
Regarding the size of the hot shoes, these days most people (except Sony of course) use the same size but they pretty much all use their own electrical contact layout which does not affect the use of a bubble level as there are no contacts on the plate.
