Tele-Cine/Scan

Film scanner - 22MP scans slides (positive) and negative



I have performed telecine from a standard projector against a screen a couple of times before with ok results but I know that this is not the the way to get the best images from the film.
I have previously researched converting my Eumig projector into a telecines machine using a condensing lens and a first surface mirror with minor (and a couple of major) modifications. The images in the converted footage from the guide I found looked fantastic. This however would only convert 8mm footage and I am looking to also process 16mm. I could though use the lens and mirror with a standard 16mm projector without much issue at 24fps (as to capture 18fps the most used super 8 frame rate without flicker in the final image, it needs to be adjusted to run at 16.66fps) . The only real issue would be having to crop the image again once telecines has been performed making the image smaller than it should be or is capable of being.
I had a lot of trouble locating an appropriate condensing lens, the first surface mirror I could make if necessary. During this time hunting I by chance came across a film scanner that can scan slides 35mm 110mm and Super 8 positive and negative images.

 It has a 22 megapixel sensor, the sample images looked very good (these of course will be of slides the largest image it can scan). It seemed strange to me that if it could scan super 8, why could it not scan standard 8 which obviously it must be able to. I did some quick research into the width of 110 film which I found was 16mm. A scanner able to scan 8mm 16mm and 35mm seemed like a great idea and so after some deliberation I ordered one. It has no form of film feed which would make it too good to be true. But ultimately I will look to automating it. I have removed the film claw mechanism from a broken super 8 camera and hope to construct a super 8 drive mechanism for the scanner from it. for now it will be great for saving instant positive previews of the negative images.
