First one - Vivitar 28-200mm F3.5-5.3

1) Buy only original 28-200mm as in picture below. Tokina is absolutely different lens with different optical formula (look at crop from Vivitar box, Tokina have fewer elements).
2) For Pentax, lens could come either in PK/A or PK A/R mounts. In former you must remoive Ricoh pin. On both you must use file to remove excessive lever protection.
3) Closed down, lens is PP friend. Good wide open, but as on many old lenses have some abberations. Contrast is lower due to many glass surfaces and not top-notch coatings. Abberations are almost absent if close down (see below).
4) Corners are controlled quite well.
