There is so much going on in the glass world these days with many major glass companies pushing out beautiful new and often expensive still and cine lenses. I've been lucky enough to have collected a lot of manual still camera lenses (FD) as a hobbyist when I was young that has now turned out to be pretty good glass that covers super 35 and beyond with digital sensors. I've had a lot of it cinevised by getting them declicked, adding focus gears and standardizing the fronts at 80mm so they all work with a matte box. I've done similar cinevising to a set of Contax Zeiss lenses as well. The zeiss are similar to the lenses that they produce today. I've done a full feature with the Canon FD's that came out great. They have a softer look than todays very sharp glass and they work great with the new digital film cameras (I use them with a Red Epic X Dragon). There is a lot of great older glass available on Ebay and through sites like KEH. It is worth checking out as these older lenses can give you excellent results. PL mount glass is a lot more expensive. I do have some modern PL glass that is very sharp and excellent for commercial use. My goal is to someday have some PL mount anamorphics. I really love that look.
