My daughter is at it again. She went to a flea market and found the following Pentax camera and lenses for sale: She was only interested in the camera strap! Seller wanted $30 for the whole shebang. Daughter offered $20, and the sale was made. The lenses are: 50mm f1:2 SMC Pentax-M lens in K mount 100-200mm f1:5.6 Super Albinar lens in K mount Samigon APK Auto Teleplus 2x converter No idea who made the "Super Albinar". Glass seems to be in good shape, focus and aperture okay. The zoom lens is really loose - Lens creep if tilted up or down. The shutter speeds on the camera seem reasonably accurate. There's a CR44 battery in the bottom that runs a light meter that also appears to work, but I have not checked the accuracy. Anyone know anything about these lenses? Should I bother getting an K-mount adapter for the NEX? I certainly would only get a physical adapter - These aren't worth paying for a focal reducer version.
