everybody is free to believe in what she/he wants, but the mamiya AFD 2 and 3 are not even a far relative of the old mamiya 645 super or pro as per build construction and features..
saying that we attaching a 30 grands back on a 30 years old j body is completely inaccurate to say the least.
have you had a play with an old mamiya 645 pro lately? ive owned the older afd and grew up with the 645 pro. sure the afd had auto focus, but it was a horrible camera in comparison to the m645pro.
fast AF isnt particularly usefull with only a center point, unless shooting subject close to the center, or slower f-stops.
also the pro had-
-fast lenses, 2.8 300, 4.0 500, 1.9 80
-leaf shutter lenses, 45, 80, 150mm
-waist level finder
-strong and reliable (my afd was a dog)
the pro definately has far more usable features and accessories.
sure its old, but i really dont know why they just didnt develop the already proven, popular camera, instead of trying to guess what a professional photographer wanted.
i have only used the afd2 once, and it had all sorts of connection issues with the p25 that was on the back of it, the dealer came over and replaced the body, and luckly it ran for the rest of the day.
