For sale is a 90mm f/3.5 Mamiya K/L lens and its accompanying 77mm Mamiya rubber lens hood. Front and rear caps included. The glass, aperture blades, etc. are pristine. I just find myself using my 180mm and 127mm lenses more. As disclosed to me by the original seller, there is one blemish with the lens: "Only issue I've found with the camera is that the mounting flange on the 90mm is a little out of round, so it's harder to mount than the 180. It does mount properly however, and doesn't affect the operation of the camera in any way." I can confirm that this lens doesn't mount particularly smoothly, but it does mount and this lens's optics are perfect. To sweeten the deal, I'll throw in the Mamiya No. 1 and No. 2 extension tubes, as well as the adapter ring that allows the lens to be mounted on RZ cameras as well as RB cameras. $200 via Paypal, plus $15.45 for shipping via a lare USPS priority flat rate box. US shipping only.
