Trying to do this the wrong way. Telescope companies have made the product for years. It is called a telecompressor. It fits between the camera body and lens. Looks just like a teleconverter. Works in reverse. T Makes the projected image smaller. Can't go too small or it won't fill the frame. The one I have is a Celestron. It also makes the lens BRIGHTER!

Think about it- any time you increase magnification without making front element bigger you lose light (teleconverter). Anytime you decrease magnification and leave the lens elements the same size you gain brightness. Camera companies stole the teleconverter from telescope manufacturers. To bad they don't steal the telecompressor. My F10 Celestron becomes a F6.3 with telecompressor. Very little quality loss since you aren't magnifying the prime lens defects (like teleconverter). Center may lose a little sharpness - edges are actually better (has built in field flatner).

Is there any adapter that will convert my lenses to the original field of view ? For example my 50mm is 80mm in APS-C and I want it to give the 35mm equivalent field of view I get in the 35mm. I don't care if I will loose an f-stop , cause obviously it will use glass elements to achieve that . I just want my 55mm f/1.2 to produce the same field of view that it does on my 35mm film camera.

Thanks !
Check out the Canon EOS 5D Mark II. The only really viable way to do what you want is to adapt your lenses to a full frame camera.
