Has any one tried PK+MM (WR) version on K5II?

starjedi · 09-09-2014, 06:31 PM

Very attempting to do it. But the shortcoming is to loose partially the weather resistant of the body. Has any one tried? Is it good to mount Nikon AI/AI-S lens?

Here is the link I found:

Here is what I got from the seller:
Some Nikon AI/AIs mount is not compatible with the current PK+MM due to the protruding tab hitting the mirror box chamber. The Pentax DSLR's APSC mirror box chamber would prevent these lenses from mounting fully. You can also check against your lens as shown in attached photos with the following steps:
1. The lens mount surface to the end of the black metal guard is less than 9mm.
2. Even if condition 1 above is satisfied, like your case, the protruding tab will most likely be more than 9mm and will need to be trimmed off.
Although I suggested modifications, I will not recommend it here as not everyone is comfortable with them. Also I cannot guarantee its 100% success after modification.

quite a few of my Nikon lenses don't fit. Seller is great, returned and fully refunded.
I ended e mount cameras.
Hope that helps.

The last I read on their mount was that they were working on a sealed version, however they did not indicate when they thought that it would be ready. I am just waiting.

They do have the sealed version that works on WR cameras.

Yes. But the current sealed version will make WR camera not WR...
