This listing is for the Pentax 35-80mm lens shown in the pictures. Please see the pictures.
The 28-90mm lens is in a separate listing and is not included. You can compare the two lenses in the images. The 35-80mm is on the right in each picture.
These are sold as-is. They do function, but they are not the greatest build quality. Normally they are used on plastic Pentax cameras in the ZX or MZ lines. They can be used on contemporary DSLR Pentax cameras, probably not covering a full frame, probably best used on APS-C cameras like the Pentax KF or KP or K-5.
This lens does work in AF mode on K-5, KF, KP, ZX, and MZ cameras.
