Hello,

I own a round front 75mm Lomo anamorphic lens. I want
to shoot some of those Lynch-style (when he was still
shooting film) macro closeups. What is the filter
diameter for this lens? Some of these diopters are special order and cannot be returned. :unsure:

Would I be better off buying
an oversized diopter and mounting it in a mattebox
instead of a specific size? It would be cool to to
use the diopters with my 35mm square front anamorphic lens too.
What do you all think?

If you are going to make something the easiest thing seems to be to build some kind of extension tube, that way you also are not putting more glass in the optic path, assuming I am understanding right what you mean about wanting to shoot macro.

Be interested to hear if you work something out!

Thanks for the response.

I guess I don't want to shoot THAT sort of macro shot. I know there is a lot of light loss using extention tubes, and I have a slower F=2.5 lens.

Extension tubes won't work with an anamorphic.

The backing lens and the anamorphic section focus differently.

Do tele-extenders work with anamorphic primes?

Yes.

Of couse there is a light loss.
& on shorter lens the rear element might not clear the elements in the extender.
But the same holds for shorter spherical lenses.
50mm ought to be okay, 35mm...maybe, maybe not. Depends on specific lens and extender.

Steve Morton had an interesting post on the Konvas.org site yesterday (Monday)- he lists a surplus optics company http://www.surplusshed.com/
and the unmounted len elements that could be used as a large (over 100mm dia.)diopter if anyone is interested. Take a look at the discussion list.

I'm a subscriber to that e-mail discussion :lol: I've learned a good amount of information from that list about Lomo lenses and Konvas cameras.

I checked out the site and the lenses seem cheap enough to experiment with.
