Pentax Full Frame Compatible Lenses

This classic pentax lens from 1991 has been given a new lease of life thanks to the full frame pentax k 1.

Pentax full frame compatible lenses.

I understand pentax are producing new lenses but a more interested in the lenses i own already as given the cost of the full frame it s unlikely i ll be able to afford more than the cheapest of the new lenses for a long period. The pentax hd d fa 28 105mm f3 5 5 6ed dc wr is a solid full frame starter zoom but it makes the compromises you expect from a kit lens. If you re looking for a pentax lens to use on the new full frame pentax k 1 then you have the option of using a pentax fa full frame ff lens or using a pentax da lens with the aps c crop feature. Pentax s real autofocus lenses began with the f series the ill fated af series consisted of only one lens and one camera body that could use it f series lenses are fully compatible with all the capabilities of pentax digital slr s except for the transfer of mtf data from the lens.

At present pentax offers a mixture of full frame compatible lenses including a handful of screw drive fa prime lenses from the film era and the much loved 31 43 and 77mm fa limiteds from the late 90s early 2000s. Some users report that the da 40mm does cover the full frame and that some da zooms at least at some focal lengths also cover the full frame. While the lens does fit the body the lens will always stop down to its smallest aperture during exposure for example f22 which limits practical shooting. The newer da 60 250 unlike other da tele zooms has an image circle covers full frame also although the vignetting is serious from 135mm and onwards.

It s one of the few full frame lenses still available from the film era. I got to thinking about which lenses are compatible. Find the right dslr lens for every photographic opportunity. Seems to be a lot of differing information out there so hoping for some clarification.
