Just took off the ricoh pin. Dind't need to cut the black piece
Works perfectly!!!

Thanks for everything

Thank you so very much! Will try it tomorrow with much calm

PS- My lens is precisely just like the one on the guide so I'm really optimistic!

No, the thing that seems to forbid the locking is the little part (a black ring with a little metal part that meets the camera body) that is in the middle of the lens.

Thanks! Specially for the duct tape version (didn't tought of it but in a last resort )

I was thinking that I might cut the part that doesn't allow to get lock all the way down, but then I'm affraid that the lens for some stupid reason will stuck inside and not get out (insane thinking on!). Is it possible to try this and work out?

Thanks

Hello from Portugal

I recently bought a really cheap manual focus lens to complement my pictures.

It is a Sirius 28-200mm for the K1000 camera. And the seller told me that it would fit the digital models such as the K10D.

So I've received it yesterday, it's in imaculate condition, but it doesn't lock on the body. This is, it enters the camera bayonet but when I try to rotate it to lock it doesn't go all the way.

It works with very good quality (for an old model) but I have to keep on holding the lense so it doesn't fall on the floor.

Any sugestion or resolution to make it fit?

Thanks
