Results and tests with the TC: http://photographybanzai.com/2011/01/...http://photographybanzai.com/2011/06/...http://photographybanzai.com/2011/04/...This video shows the Kenko teleconverter work with the Pentax camera SDM auto focus.It was pretty dark and the position to the subject was not changed. The camera without the TC attached seemed a bit odd as I had to half-press a few times for the camera to gain absolute focus except for one time when it went directly to the focus position. That was probably just a fluke, so I'd say in general the teleconverter makes focusing a bit slower. I usually use the setup with my K-7 instead, which is faster overall.--------------------------------------------------------------------If you enjoy my content, please consider subscribing: https://www.youtube.com/channel/photo...Social Media:Twitter: http://twitter.com/photobanzaiInstagram: https://www.instagram.com/photography...Facebook: https://www.facebook.com/PhotographyB...Flickr: https://www.flickr.com/photos/photogr...Amazon homepage affiliate links:Using these helps me out at no additional cost to you.USA: https://amzn.to/2pPYBz0UK: https://amzn.to/2GmvQ83Canada: https://amzn.to/2uC6GwUGermany: https://amzn.to/2GsLpr6Spain: https://amzn.to/2GjEm7QFrance: https://amzn.to/2uBgDKTItaly: https://amzn.to/2J3gcwhEquipment kits I've assembled:Links on there are affiliated as well.https://kit.com/photographybanzaiDonation links:Using these directly helps me continue my work on this channel.Paypal (best): https://www.paypal.com/cgi-bin/webscr..."Buy me a coffee": https://www.buymeacoffee.com/hpPvwGDSM Ko-fi: https://www.ko-fi.com/photographybanzai
