Hello, I'm selling a rare and ultra-lightweight 8mm Berthiot S.T.O.P. "Baby Hypergonar" anamorphic lens, designed by the Henri Chrétien, inventor of the Hypergonar and anamorphic lenses himself, in excellent condition. The lens is on ebay Germany now:

The real point of the 1.75:1 ratio is related to the change in CinemaScope ratios soon after its inception. Early CinemaScope was filmed with 2:1 ratio giving a 2.66:1 Ratio from a standard 4:3 Academy frame. Subsequently, the ratio was reduced to 2.35:1,which needed a 1.75:1 (actually 1.76)compression to fit the standard frame. However, Super 8 Commercial prints were made with a 2:1 compression, which accounts for the black masking at the frame sides on Super 8 to achieve the correct ration on screen. I have a beautiful Magnarama 1.75X Anamorphic which I used to use for filming: this gave me the correct ratio. In addition to being focusable for filming it has large front and rear elements. The attachment I use for projection of Super 8 Commercial prints is my Home Made one which is now over 55 years old!

No, Commercial prints are made with a 2:1 "squeeze", so for projection of such prints you MUST use one of the many 2X Anamorphic attachments. This lens is intended to be used with 8 mm (and Super 8) cameras and projectors for making YOUR OWN "CinemaScope" films in the correct modern CinemaScope ratio. Martin

Actually the lens is perfect for the screening of commercial film, because a 2x compressoin actually makes the amateur screen just slightly too wide,because the professionals used up that little bit of their film for additional soundtracks.The correct aspect ratio being 2.33.1 whereas ours is 2.66.1.Therefore the little Hypergonar is perfect,as you'd expect from it's creator.

Hugh, I think you are confusing "Screen width" with "People width". If the print has been MADE with a 2x, it should be PROJECTED with a 2X, otherwise people with appear thinner on screen. Not a lot, but nevertheless thinner. A sort of compulsory diet? That's why, as I mentioned before, the width of the image on the film is actually LESS than the frame width (Black masking)giving you a 2.35 picture with a 2X anamorphic. Martin

With respect Martin.it's us the amateurs that are in fact overstretching the image by projecting at 266.1 whereas the professionals use 2.35.1.The only "true" 'scope prints are the ANIMEX prints that gave the full aspect ratio to avoid cut off and also cure the over stretching by the black bands either side of the screen.

On reflection Martin,you're absolutely right and I'm wrong,of course if it's shot in 2x and shown 2x it's got to be "normal" my apologies.
