Hey guys. I realize anamorphic Super 8 has been covered multiple times on these boards, but I figured I would post my situation and see what my options are.
I currently have in my possession an [2x] ISCO Cinemascope Ultra Star Plus 21 projection lens. It is quite small and compact, and the lens unscrews into two pieces, separating the anamorphic element from what I can only describe as a magnifying element. I have used the anamorphic element to desqueeze scope films projected through a 4:3 native projector, and the results have been pretty awesome.
I'm in the process of purchasing my first 1014-E, which I believe has a 58mm thread size. I am currently unaware of the thread size of the anamorphic lens, but I have a lens technician friend who is going to measure it for me so I can attempt to locate/purchase the appropriate step up/down ring. I understand that should I decide to mount the lens to the front of the 1014-E zoom lens (a 7-70 macro), that my focal length would probably have to remain pretty consistent.
Anyone have any experience in attaching anamorphic lenses to the front of zoom lenses? Vignetting will most likely occur on the wider end, but once you zoom in to eliminate the vignetting, are you free to play with the remaining focal lengths, or will zooming past the "sweet spot" of the anamorphic element cause distortion?
I've seen filmmakers use "mesmerizers" in front of their lenses before, and this thought always crossed my mind.
Any help appreciated!
