    Strength:

    I just got a nice used Pentax 645n and 55mm/2.8 SMC-A lens to compliment my Bronica RF645 and its excellent 45mm and 65mm lenses. I love having an f/2.8 close-focusing moderate wideangle, but am thinking about the telephoto end now. I am thinking of getting the SMC-FA 150mm/2.8 IF tele whch seems to have a great reputation, and was wondering if it performs well with the Pentax 1.4X teleconverter? I think I would mostly use the 150mm alone, but occasionally would like to go longer. I'd rather not buy a 200mm/4 that would be used only rarely. print stickers | sticker printing | printing services | business printing

    Weakness:

    I couldn't find a post about this 150mm/2.8 + 1.4X combination, though I ran across someone who said they were disappointed with the 150mm/3.5 manual focus lens and the 2X teleconverter. Is the 150mm/2.8 better on teleconverters than the 150mm/3.5? Any opinions would be appreciated.

    Strength:

    Size, sharpness and economy of not needing to buy the 400/5.6 lens.

    Weakness:

    None

    Works great with the 300/4 ED/IF. Some decrease in sharpness but hardly noticeable. I haven't used it with other lens to be able to comment on it.

    35mm converters but no real comparison here. I have used the P645 2x but find it kinda soft.
