PENTAX SMC PENTAX-M 150mm F3.5 A peculiar focal length prime lens series from Pentax Thank you for viewing. I am selling the Pentax lenses I have been using to raise funds due to a mount change. Please understand that these are for practical use rather than for collection. I used them with the K-3 III and KP. I don't think there is any significant mold or haze optically, but there is some dust and debris. I think it's in good condition considering its age. Please note that I cannot accept price negotiations. Also, this is a used item that will be delivered as is (treated as junk due to amateur inspection), so please refrain from purchasing if you are sensitive to such things. Please ask any questions before purchasing. - Brand: PENTAX - Model Name: SMC PENTAX M150mm f/3.5 - Lens Type: Prime Lens - Mount Type: K-mount
