A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Weather sealed zoom lenses with non static rear lens element, how do they maintain airflow? (alien.top)

Say Nikon Z 24-70 f 2.8. It has a lens element near the mount which moves as we zoom. This means, air will be pumped into the camera. How will the air exit?

Air can move internally in a lens. Moving the lens doesnt change the air volume inside the lens, as it was already in there. With that said lenses arent air tight.
