I have the K5 as my second body to go along with my D*300MM lens. I havn't been able to find a 1.4 Teleconverter for it. I trid some of the Sigma's, but could not get them to properly function. Messed with the camera's electronics. I am here in Canada, and it seems no one here can give me a straight answer, as to whether there is a match out there for me. I love the lens,but would love to further my shooting distance. I would appreciate any advice anyone might have. Thanks, Wayne

Hi All, I am new to this site, and was wondering if anyone could help me find a Teleconverter for this lens. I have tried the sigma 1.4 & 2.0 converters, and they would not function properly on my K20D. We couldn't get the AF to work. I love this prime lens, for many reasons, & would like to be able to shoot a little further.

Thanks, Wayne
