I had a request to provide unprocessed full resolution images from the airshow I went to recently where I used the K-5, DA* 300mm f4, and Kenko 1.5x Pz AF teleconverter together. I’ll be providing a few images with 100% crops straight from camera raw default settings for your viewing pleasure. The first image shows some movement blur and how well I did on tracking with AF. This isn’t a representation of absolute sharpness, but rather what type of result you might get in extreme conditions as long as you gained decent focus on the subject: The UPS plane was stationary, so this is a better representation of sharpness (long distance from subject): This person’s t-shirt is also a good representation of sharpness (close distance from the subject):  I still see some motion blur in this shot, but most of the text is readable: Another result which might have benefited from a faster shutter speed: Doing a little math that combination gives me around 680mm in full-frame terms. I think in abs...

Recently I had a question about the Kenko teleconverter about if it functions with SDM lenses and if the teleconverter hurts image quality. I thought this was a good request and warranted an article or two on the blog. If you are not familiar with teleconverters (TC for short), they attach between the camera and lens allowing you more reach, or rather more magnification. Some people feel they are not necessary and hurt image quality, but I personally feel they can be of use and some of the available teleconverters don’t cause large drops in image quality. Here is the Kenko teleconverter sandwiched between a DA* 300mm lens and K10D camera body: The lens, teleconverter, and camera. Pentax does not have any teleconverters available in the USA for sale, but private sellers at places like the pentaxforums.com marketplace have a few options available. The Kenko Pz-AF 1.5x Teleplus SHQ is an older teleconverter that is still available in Japan that is available here through those secondary me...
