Planar 80mm on dslr question?

[vdubbin099]

Hello, I have a planar 80mm f/2.8 T* and I found a adapter on ebay that says it will adapt to a pentax dslr. I was wondering if anyone has tried this with any dslr? Also is there a way to keep the shutter open on the lens so I could just use the shutter in the dslr? thanks for the help

Any advice on how to keep the lens shutter open so I could use it on a dslr would be greatly appreciated. I was given this lens however I don't have a hasselblad (ye) so I am not sure if it is even possible to keep the shutter open. thanks for the help!

That is quite simple:

Look at the rear end of the lens.
You will find a slotted shaft.
Turn that shaft with a small coin fully clockwise untill it locks.
The lens will stay open because your adapter does not engage with the lens tripping mechanism.

Use a coin and not a screwdriver because that may damage the rear element should it slip from the slot.

Thanks for the help. However when I turn the slotted screw clockwise the shutter only stays open until I let the coin out of the screw and the shutter immedately closes.

Keep turning untill the shaft locks.
If it does not when you can not turn the screw any further your lens has a mechanical problem.
That is not very likely. You probably stop to early.
