I must say that I am quite enamoured with the Rolleiflex 6008AF. I only have one lens, the AF 80/2.8 Xenotar. I am thinking of buying the AF-Longar 1.4 teleconverter so that I can effectively have a 120/4.0 lens for much less money than buying a separate telephoto lens. Do any of you have any experience with this teleconverter? Does the autofocus work well with this device? Also, what has been your experience with the 4560 magazine? I note that one needs to use an adaptor frame for this magazine. So how cumbersome is it to switch between the 6x6 120 magazine and the 4560? Thanks very much.
