Notice of Compatibility for Pentax Full Frame DSLR K-1 and Pentax K+ Multi Mount (PK+MM)
Thank you for your interest in our products.
Since the much awaited announcement of the first ever full frame Pentax DSLR K-1 by Ricoh Imaging in February 2016, we have received multiple enquires if our product, the Pentax K+ Multi Mount (PK+MM) WR version can be used on it.
As the Pentax K-1 DSLR will only start shipping in April 2016 and stock availability of this much awaited DSLR will be expected to be limited, we will not be able to provide a full confirmation on its compatibility until we are able to get a production version of the K-1 DSLR for verification physically or through other confirmatory methods.
Although our initial investigations using information from high resolution photos of Pentax K-1 from Ricoh imaging official sites, trade show and hand-on reviews from multiple sites conclude that there is no external design changes, we are not able to determine its compatibility. This is because the obscured (hidden) areas of the K-mount ring in photos may contain new design features which is different from current K-mount ring used in APS-C DSLRs.
We are sorry that we cannot post any photos due to possible infringement of photo owner copyrights so we have provided links to them as listed at the end of this notice.
Once the information on Pentax K-1 and PK+MM (WR version) compatibility is available, we will announce it on our official website. You may wish to sign up for our mailing list for email notifications on all news related to our products.
