HI friends, I have recently got a bronica SQ AI with the 80mm , 50mm and the 200 mm lens set. After having picked up the medium format, I have hardly touched my Leica M2 as I am now so more interested in landscapes and the great viewfinder just makes the entire process so very magical. But its heavy and I want something that I can shoot handheld and hence looking at the 6x45 as they are lighter than my 6x6. Thinking of selling my Leica M2 and the voigtlander 40mm for a 645 medium format. But the questions is which one :- 1. Mamiya Pro TL or AFD. 2. Bronica ETRSI 3. Pentax 645 Nii. I am leaning towards the mamiya as I want someday to get a digital back down the years. Please let me know your views on the same.
