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.
I spent Saturday doing some yard work, mowing, hoeing the small vegetable garden my wife and I plant, and fertilizing a couple of apple trees we have in the back yard. After the chores were done, it was a beautiful day with temps in the mid 70’s, so I decided to have a beer, kick back on the deck, and enjoy the rest of the afternoon. Soon I remembered I had a new lens that needed test shooting. It’s a Pentax 55mm 1.8 made in 1976, and reported to be one of, if not the sharpest lens Pentax ever produced. I spent the next 30 minutes shooting and here are some of the pics. Let me know what you think.
