Perhaps this will be even more advantageous - I suspect that the lens may be actually focused on the hiperfocal > distance in such case. However, it seems to be no way to use large apertures (below f/8) Sounds like the mount isn't shimmed correctly. I bet putting another few thousandth of an inch os shim in there would fix it up for you. William Robb - This message is from the Pentax-Discuss Mail List.
