Hello everyone. With super 8s small aperture I am curious what size image everyone is projecting and your seating distance. Our light source without modification will not allow us to go to large but curious if anyone is pushing the limits of super 8.

When there was still a big l internationasuper 8 film festival in Brussels, the films were projected (with a Beaulieu projector) in a cinema and the picture was full screen. The last time I went there (about twnety years ago) there was a mix of super 8 and video projection. The video projection had a smaller size than the super 8 one and had a very poor quality (again, it was about twenty years ago)comparing with the super 8 films.

Hi Alan,

I think this thread would be of your interest:

A lens you need for short throw problem

This is one of my experiment:

 -

This is what I got with my throw distance at 4.8m (15.75 foot)
Projection at 12.5mm (height x width) = 2m x 2.66m (78.74 inches x 104.74 inch)
Diagonal length: 130 inches
Brightness: Decrese by 10% (but then I compensate by switching the light setting to high instead of low)
Sharpness: no change

When i do our outdoor films in scope....it's a 16 foot wide screen and there's no problem with brightness or sharpness. My regular screening room is only about six feet wide.

Mine is about the same as Janice's. A 15' distance with a picture size usually about 86" on my 96" screen using the f1.0 lens. Alan, still waiting to hear how the quality of your SON OF KONG feature is. Please do a review, or send me a PM or e-mail. Thanks....

Hi Alan,
Good to see you posting.
Compared with modern home digital projectors, most super 8 projectors are pretty dim. I have a Eumig 938 stereo with 150 watt lamp, which I usually limit to a 6ft wide screen. And that's with an f1.0 lens.
My 2- bladed GS1200 with the Fuji 200watt ESC lamp and the Elmo F1.0 lens can go up to 8ft wide, but IMO anything beyond that is too dim.
I do project scope films up to 115 ins wide with the GS1200, and the picture is acceptable but could definately be a lot brighter.
On the Eumig 926 GL that you have, an F1.0 lens makes a huge difference.

My back garden is about 50ft. long and at the end is a huge blank white wall of my neihghgbour's house. It is great fun projecting films on to this wall from my Eumig 710 Lux machine on a dark night!!

Once (about 15 years ago, where I lived before), I did something inspired by "Cinema Paradiso". I tried to project a film (for a less than a minute) on the wall of the house in the street in front of the window of what was my living room. It was with a small 16mm handcracked projector with a non powerful lamp and, surprise, it worked !

Everyone's projecting a larger then I expected.

Janice that is a good size. In the past I did not have a permanent setup so I set everything up on a shelf and watched everything projected on a white wall at a whooping 3 feet wide. Of course everything looked great at that size.

Dominique I agree with you. The digital transition still looks like video to me but it is getting better. 4k pixel fill helps that digital glare from 2k on a really big screen.

Winbert good stuff. Im on the lookout for such a lens. Looking forward to a larger image.

Gary I can image the fun you must have had. That is almost a true cinema size screen well beyond most home theater systems.

Joe I plan to screen the print next week. I will send you a PM. I did screen one reel and it looked good I was happy with the quality but nothing like watching the entire feature.

Paul nice to know there is someone not to far from me with top setup. The GS1200 is very rare Ive been looking but most are scooped up. The Eumig I bought from you throws a nice bright picture it is a great little machine.

John as noted those Eumigs throw a nice bright image. Funny how some of the projector designs are more efficient then others.

Dominique your getting lazy, while you were cranking that 16mm you could also pedal a bike to generate some power for a brighter lamp. After a full feature of cranking and pedaling you
may need some oxygen.
