The LA7200 is the anamorphic 1.5x use un digital video cameras like Sony & Panasonic.

Yes you can use the entire zoom range and the macro also.

when super 8mm is transfered to digital you can pull the image to 1.78:1 ratio like HD.

The LA7200 is not a standard lens system is a front atachment for standard lens system
is only an horizontal compressor cilindrical lens.

this is an example for a cinemascope adapter:

Bogdan,

It is better to start a new thread with your question than piggy-back on someone elses, especially when the questions are different. You will get more answers in your own thread.

To Joseph the Great,

I took into account your idea - even if launched to me in a very flegmatic style - and I already started a new topic. I considered that it was a good idea, unfortunately, comming from a unappropiate person. I hope now you will feel your self "piggy-backed" no more. So, thank you for your super 8 mm kindness :P

Rolando,

Great application but I was wondering how do you keep the LA7200 straight when focusing without support bars? Or do you just manually straighten it out after focusing?

Hi Will! , yes for now I have to hold the adapter until focus is ok but it doesn't cause so
much problem if I were to shoot below 40mm , it definitly works, I know you now that...

Hi , super 8mm is not a HD frame ratio you will have to use an adapter like this to get the 1.78:1
aproximation ratio. About the camera I canot tell because I haven't use a Chinon yet ,but it looks
like is a good camera.

Thank you so much Ronaldo. I think I will make all necesary efforts to put on my Chinon an adapter like the one you mentioned here. I hope I will find on internet a good adapter for Chinon. And you know why? Because I already shot a medium feature with a Sony HD video camera (ratio 16:9) and in the final version of my digital movie I try to insert few fragments of motion picture film (super 16 mm and super 8 mm), all of them, of course, calibrated for HD projection. As I now so far pro8mm.com has special stock of super 8 mm already prepared for HD dimension. It is true? (I appreciate your effort in answering me)

i thought about going this route but decided against it for a couple of reasons. the focusing issues were a concern. the big one was the lenses are designed for standard def and not 1080 so there would be a loss in quality. if i remember right i did a calculation and it turns out that going maxi8 loses very little of the frame and you can do a 1080 scan. is there a 1080 scan available for a 4:3 image thats been squeezed?

These Century Optics/Schneider 16:9 conversion lenses have better glass in them than the Panasonic, at least as good if not better than most super 8 camera lenses.. I doubt super 8 has the real resolution of 1080 anyway.

That is right , Century has a little more correction on the borders , but for the final
resolution in 8mm is not perceptible.

The 8mm film can show about 800 lines this lens is for aspect ratio basicaly it will not increase
any resolution at all.

I also have tested a Century on a Minolta.

saying 800 lines in super8 is relative to stock, glass and camera. if you are using modern glass, low speed stock and have great registration (i'm lucky i have the best registration) then who knows what the resolution is going to be. im just thinking that having the best you can in terms of optics is the best way to go. im concerned with the hassle of backfocus with adding an anamorphic on there especially since im thinking maxi8 uses the same (or close enough) frame areas as a squeezed image wihtout the hassle of adding glass, stressing about focus, limited telecine/res. dont get me wrong, i was all over this a couple of years ago but then personally decided that a widened gate was the better idea. if it works for ya then kudos

I use the Century Optics lens on both the Cinegon 10mm prime and Fujinon 5.5 mm prime with my Mekel, get no vignettting and no problems with back focus which happens more on zoom lenses. This set up is so simple and gives fantastic results plus the short focal length is hard to find in modern prime lenses for 8mm. With the 5.5 prime you get more the viewing angle of a 3-4mm lens which is quite wide for any camera. Plus you know exactly what you are composing in the shot instead of guessing. There's no way I'm gong to mess around with widening the gate on my Mekels, the danger of light leaks is too much.
