i hve several cf lenseswith which i can engage the depth-of field-button, but i cannot release the button no mater how hard i push. is there a trick i missed?
This is an annoyance for me also. However the lenses are so sharp fully opened that I now rarely bother to check the depth of field any more, because I know that it will always be better than what I am seeing.

I leave the digital work for the urologists and proctologists.
