Yes. Look at http://kmp.bdimitrov.de/extras/K-mount/K.html > Specifically, I am using the auto bellows and a 100mm macro lens > and am consistently getting underexposed negatives.

But if the bellows does not have an automatica-aperture coupler, the camera does not know that the lens will stop dow 2-3 stops. Now, if you were using an LX or a flash, it would work. Otherwise you need to overexpose by so many stops as you are closing the lens from its widest aperture. Good luck, Boz - This message is from the Pentax-Discuss Mail List.
