Will this lens cause problem on my K30 / K5 ?

micl161 · 05-26-2018, 07:48 PM

Hello,

Came across a old Soligor zoom lens on Ebay and like to give a try, the seller mentioned it should fit the Pentax PK mount.

The lens' mount is as following photo, it seems it didn't have the 'Ricoh Pin' but looks there is another pin protude out.

Will this cause issues ? thanks.

Good catch Dave!

Interesting, it is similar and k/ar seems like the rikenon with the dreaded pin. The k mount locking notch is missing.

People see the "K" designation on 3rd party lenses and assume it stands for "K-mount". Lenses for Pentax K-mount are typically marked as "PK", "PKA", "P/K", or "P/KA".

" Pentax K-Mount Lens Series Explained: The differences between various Pentax lens series

In a nutshell

There are several series of Pentax K-mount lenses; the ones currently being produced include the DA (digital), DA L (cheap digital kit), D FA (full-frame, digital optimized), and FA (full-frame) series. While all Pentax K-mount lenses ever produced are compatible with all current Pentax DSLRs (in some cases with restrictions in that not all exposure modes of the camera are supported by old lenses), there are significant differences between each lens series and each has different features. Furthermore some of the newer lenses do not work with older cameras. We'll be exploring the differences between the various K-mount series lenses in this article. Read more about specific K-mount lens/camera compatibility here.

The DLSR designation below encompasses the mirror-less K-01. "

" The Evolution of the Pentax K-mount
Technical Information and a Little Bit of History
By PF Staff in Articles and Tips on Dec 29, 2014

Pentax introduced the K-mount in 1975 and it's still the mount used in today's digital SLR cameras. Over the course of its 40-year history, the K mount has gone through several enhancements to facilitate new camera features. Even then, a K-mount lens from 1975 will mount on and work on your Pentax DSLR today! In fact, Pentax users are among the few who have access to such a wide range of legacy lenses. In this article we will describe the K-mount in its various incarnations.

The K-mount is a bayonet lens mount (the type employed by all modern lenses) which replaced the original M42 screw mount, thus making changing lenses must faster. While the screw mount requires three complete revolutions of the lens in order to mount tightly, the K-mount only needs a twist of about 60 degrees. The diameter of the K-mount is also larger than that of the M42 making faster lenses and more robust optical designs possible. "

Pentax bayonet lenses labeled "SMC Pentax" are referred to as "K" lenses in the table below. Other Pentax bayonet lenses have the lens designation as a part of their name as in "SMC Pentax-FA." Note that "star" lenses work like their "non-star" counterparts: DA* lenses work like DA lenses, FA* like FA, F* like F, A* like A, and M* like M.
Exceptions: FA and F "soft" lenses behave like M lenses in terms of metering.
