Edit: updated to clarify exactly what calculation I was doing.
- pletnes 6y agoThe focal length is a property of the lens and as such irrespective of which camera it is attached to.
- pmiller2 6y agoI know that. 35mm equivalent focal length tells you about the image area and effective aperture.
- roelschroeven 6y agoIt has the same (approximate) field of view on your D3400 as a 160.65 mm lens would have on a full frame camera, yes. 157,5 mm come to think of it actually: as far as I know the crop factor on Nikon crop cameras is 1.5. On a medium format camera you would need an even longer lens to get the same field of view. I'm not sure about the aperture equivalent. Aperture influences both exposure and depth-of-field, and I don't think they vary in the same way between crop cameras and full frame cameras.
