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.
Shutter speed 1/320
Shutter speed 1/80
Thanks for looking, and as always comments are welcome.
