Using two filters will also, as already mentioned, certainly result in vignetting.

This one is from a while back, but I revisited the shots from this fashion show and decided to rework a couple. The SMC Pentax-DA 35mm f/2.4 lens acquits itself well.

You won't need to enter a focal length if you are using an A series lens, in which case just set the aperture ring on A and let the camera control the aperture.
In what way are you "stuck" after switching on the camera, can you be more specific?
