Solid Adapter Mount

Mount is well-built and works great. Wanted a quality adapter to use my Pentax-M lenses on my XT camera. This does the job.

The Pentax K mount adapter fits well onto my fuji x-t1 and looks as if it is a part of the camera. The black colour is a perfect match for both the x-t1 and the Pentax M 50mm lens. The space occupied between the camera and the lens by the adapter is perfect for using a manual lens. The Aperture ring and focus ring fall naturally to the fingers while leaving a finger underneath to support the lens. This is the second adapter I have from Urth and both of them are well engineered and have a feeling of quality when you hold them.

Is aperture controlled via the lens aperture ring ...

Is aperture controlled via the lens aperture ring when using this adapter?
Asked by: Erik
Yes the aperture can only be controlled by the ring on the lens. If you have a newer lens that lacks a manual aperture ring, this Vello adapter would be a better option: https://bhpho.to/3IbSUkX
