  1. Thanks Dan, in fact I found it from that site at first but right now I have two wedges but don't know how to assemble them because I need to find a viable math formula to correctly place each prism in the right place to get the ratio magnification I want. I want to make my prism squeeze from 16:9 to 2.40:1.

  2. I saw there is an alternative to building an anamorphic lenses for projection purposes and I suspect I could use it to film it right in front of my DSLR. But the problem is I want to know if there is any formulas to ensure us that I am getting the image squeeze that I prefer.

  3. I have a sankor 16c and a sankyo LXL 250. I nearly have to zoom all the way to get a perfect crop from the anamoprhic lens without vignetting. However, the lens needs to be approximately ten feet away to get a head shot. Is there a wide angle adapter for these kind of lens?

     

    and

     

    How do I focus an anamorphic lens? Or do I just focus the camera lens or both?

  4. I get the same thing, I have a Nizo 156 Macro, and focusing is not only difficult, since you have to zoom and watch some vertical line being continuous, and zooming out again, but it also takes up so much time that it's usually not worth it, unless its a shot below f4 or a zoom or macro shot. In all other instances I estimate (sorry, no guestimation here ;) ) the distance, which is really not hard with some practice. However If you need excellent sharpness, then you better go on and try harder to focus correctly....

     

    It is not like I don't want to focus harder, but the line is not demonstration if the subject is in focus or not.

  5. I own a Sankyo LXL 250 super 8 camera. I wear glasses, and i have no idea how to adjust the focus. It is harder than focusing with a 35mm. why? I followed the manual but it is hard to distinguish if the image is in focus or not. Anywhere I turn the focus knob the screen is not really differientiating the image's focus distance.

  6. hey,

     

    we're shooting a student short film with the canon HDV XHA1, plus

    we're using a redrockmicro adapter (depth if field 35mm), using 35-70mm and 24mm lenses

    the problem is we're not able to focus when the adapter is fixed to the camera original lens so we have to move the adapter a little forward...

     

    anyone could help resolve this problem ? ...

     

    thank you //

     

    You need a focusing screen that is made for 35mm camera. try to get the ones without markings and put it between the 35mm lens and the camcorder lens. There is actually videos in Youtube where they show you how they made their 35mm extension lens.

  7. Film sensitivity

    (1) ASA 40, 160 (Type A film),

    (2) ASA 25, 100 (Daylight film)

    (3) Film sensitivity is automatically set by cartridge

     

    Filter

    (1) Built-in Kodak Type 85 filter.

    (2) Built-in filter can be brought out of place through the movie light spocket for improved exposure sensitivity.

    (3) Dia. of external filter:55mm.

     

    Kodachrome is out of production and it is harder to get each day. I want to use Ecktachrome!

  8. I sent my super 8 film for processing through CVS in 2007, walmart dident do it for me because they dont send out film anymore

     

    Who do CVS send the Super 8 film to, because they send out slide order also.

  9. Hi, I just got a Sankyo LXL 250 super 8 camera. Can I use Ektachrome 64t, the vision 2; 200t, and the Vision 2; 500t speed film with it? In the manual it mentioned that the camera has a built in filter A.

  10. "What happens if the threads is too large for the thread of the camcorder itself?"

     

     

     

    A straight thread to thread adaptor won't work because, one needs to be able to orient the directionof the squeeze.

     

    One would need, at the simplest, an adaptor which goes from thread thatscrews into the camcorders lens to a tube that the rear barrel of the anamorphot slips into and is held in place with a set screw.

    I used to have some that went from a 39mm rear barrel to various series size threads.

    For the Kowa 16H/8Z one will need a 52mm diameter barrel. Years ago I saw ones for the Kowa barrel to 52mm and 49mm threads. These particular ones were for Jon Hall's Omnivision, really the Kowa 16H/8Z. Finding them? Hit estate sales.

     

    Hey Leo, thanks for the info. If my camcorder only accept 30mm threads will there be cut off?
