I bought my Mamiya 645 Pro TL a few months ago and it came with this lens. I already have my M645 lenes, and all I need is a 80mm and a 55mm tiny primes.
I did test it with one roll and did not find any problems with the results (I used HP5+). The glass is free of fungus, haze or scratches, see photos. Focus and aperture are quite smooth. Zoom is a bit heavier, I am not sure if it's by design or due to age. Comes with the original box, the hood and some kind of UV filter.
Asking $65 plus shipping ($15).
I do not know. I am new to Mamiya, and just bought a 645 Pro TL with a bunch of lenses and this one is redundant, as I only shoot 80mm 90% of the time.
