New Pentax Toy

Picture borrowed from Pentax Forums Lens Review

I recently picked up a Pentax 2X-S converter.  This little item doubles the range of my 55-300MM DAL Pentax lens and turns it into a 600MM monster zoom lens.  Their are a couple of issues with this converter, the first and  hardest to deal with is the loss of 2 full stops of exposure.  The second problem is loss of auto focus.  Although my KX will shoot in aperture priority with this converter, I quickly discovered it metered much more constantly in manual mode and made the two stop exposure adjustment with shutter speed.  Here’s a couple of test shots.  Let me know what you think.
