Well Pentax has been making 35mm Lenses since 1952. They probably went at least 25 yrs WITHOUT offering one. They probably caved in due to the popularity of the 3rd parties offerings, but even a T6-2X is not going to give results as good as a well made prime of the equivalent focal length. TCs are a kludge at best. A 2X TC throws away 75% of the image formed by a prime, and magnifys the remaining 25% to fill the frame. Needless to say the result is a softer image and less conrast due to more elements. I dont take pictures often enuff to waste the time I do using an inferior lens system like a 2XTC. Based on my latest digital image processing and printing, 35mm is capable of excellent quality, but you need really good optics & film to achieve it. I'll pass on the TC's thank you. JCO
