I see Pentax produced two TCs, the 1.4x Rear Converter A and the 2x Rear Converter A.
I've never really researched TCs, so these are also somewhat confusing to me, but am I to assume from reading the Pentax website the 1.4 is only good on the 120/4, 200/4, and 300 due to teh fact that it has an element that sticks out, and that I would need to use the 2x converter on any other lens? My original concept was to form a kit of teh 45/2.8, 75/2.8, and 150/3.5 and then use the 1.4x TC as a fill to flesh out the kit with minimal equipment, but it looks like that's nto going to happen. Is there an aftermarket, and reasonably priced, 1.4x TC for the 645? -- http://www.infotainment.org <-> more fun than a poke in your eye. http://www.eighteenpercent.com <-> photography and portfolio.
