This is a lens that can be used with the Pentax 67. The lens type is a macro lens. Focal length: 135mm (equivalent to 66mm in 35mm format) Maximum aperture: f/4 Although there are some scratches from use, there are no noticeable scratches, and there is only a very small amount of dust inside the lens, which does not affect the image quality. The aperture blades are confirmed to be linked to the shutter, and there are no operational problems. I was using it with a GFX via a mount adapter, but I am selling it to organize my lenses. Instant purchase and price negotiation comments are welcome, so please consider it.
