I have a fantastic, very clean Leica 70-180mm that has been Cine-modded by Duclos with a Leitax Canon mount.
Been shooting it with our EPICs and it's awesome. Very long focus throw, holds focus through the zoom, tack sharp, great contrast, color and bokeh.
Judging interest before I put it up for sale.
Sell price would be what I have into it - about $5,900.
Please let me know if you would be interested.
