ken Posted September 23, 2015 Share Posted September 23, 2015 Need to use two lenses, ISCO integrated lens and Schneider ES lens. No aperture control. Taking lens is from ES lens, FL=60mm. See pictures. Quote Link to comment Share on other sites More sharing options...

ken Posted September 23, 2015 Author Share Posted September 23, 2015 I don´t understand. Can you explain it? See draft. I did not finish adjustment yet, due to the tube is still too long. But it should work. I mainly focus on auto lens usage. Quote Link to comment Share on other sites More sharing options...
robbing Posted September 23, 2015 Share Posted September 23, 2015 I see, Very complex thing. Need perfect distance with rear attachment and prime to the front one or astigmatism comes as hell.There are other way: Fix the taking lens to the rear ANA and make a mechanism that the block move in-out of the camera. This is how anamorphic Lomo primes works.Still very complex because the taking lens only need move a few mm from the sensor (Lomo´s focus ring have a pin that make this little move to the spherical block), and the cylindrical rear lens need move too much. good luck ken 1 Quote Link to comment Share on other sites More sharing options...

For most of anamorphic lens on FF, around 100mm is best focal length without vignetting. And 100mm's prime lens focusing moving distance is about 10~15mm, basically equals to anamorphic lens moving distance from 1.5m to infinity. Also only external focus lens can be used. The advance internal focus lens cannot. Quote Link to comment Share on other sites More sharing options...

I believe it's an ISCO projection lens. They usually don't have an aperture control so you're gonna have to shoot wide open. You can make a simply whole grab adapter to use it with a Chinese helicoid to focus. Quote Link to comment Share on other sites More sharing options...
webrunner5 Posted April 30, 2022 Share Posted April 30, 2022 Well, he ought to get an award for the ugliest Anamorphic Lens setup. But hey if it works why not. 😁 Quote Link to comment Share on other sites More sharing options...
leslie Posted May 2, 2022 Share Posted May 2, 2022 are these the isco's that need an allen key on the front of the lens for adjustment ? because thats a total pita. i vaguely remember looking at one, years ago and thinking as desperate as i was for an anamorphic, i could wait for something better to come along.
