I had considered that option before but huge amounts of funds was not really required for this product to materialise. And to gather publicity through Kickstarter seems to require more efforts (with less results) than posting on Pentaxforum especially when you have a product that appeals only to Pentaxians AND manual focus users. If those that received their PK+MM would post their own short review of it, that would be a good spread of news.

I just finished testing PK+MM with some film SLRs. The findings are linked below. I cannot test all but they should apply in most cases.

A few people may still remember my winning entry to last year Pentax Forum K-30 giveaway where I shared my “Influential gear” ( PentaxForum Entry ), a self modified K mount ring to accept Nikon F, Olympus OM, Contax/Yashica C/Y and Konica AR* mounts lenses in addition to K mount on my Pentax K-r.
As the response then was encouraging and as promised, I have made it into a commercially available product which I called it Pentax K+ Multi-Mount (PK+MM). There is now no need for users to try DIY now since they can now replace it with this new mount ring instead.
Here is the photo of the PK+MM on my K-r.


The concept behind this possibility is although different camera mounts are different, by re-designing the K mount, I managed to allow the mounting of other mounts as mentioned. No adapter is required and no lens modifications required except for a minor one for C/Y mount. Of course, there are lens mount markings for the different mounts but lens locking is not available. However, the lenses do stay on quite snugly with the leaf spring in the camera body holding on to them. Operation wise is same as using M42 screw mount lenses.

I will share a few photos, especially for those who are interested in adapting lenses.

Nikon 50mm F/1.4 (pre-AI) Nikkor-S Auto on Pentax K-r beside Nikon SLR Nikkormat


Nikon 28-70mm f/3.5-4.5 AF on Pentax K-r beside Nikon SLR N90s


Olympus Zuiko-S 50mm F/1.4 on Pentax K-r beside Olympus OM-1N with Zuiko Auto-MACRO 50mm F/3.5 with Varimagni Finder attached.


Yashica ML 50mm f/2.0 on Pentax K-r beside Contax 167MT and Yashica FX-3


Currently, only the version for non-WR bodies is completed and available. I am still working on the more complicated WR version. And these are made in my home country, Singapore.
