Diopters for my Lomo anamorphic Round and square fronts
Posted 05 March 2011 - 04:20 PM
Also for my Lomo Anamorphic Roundfronts 50mm and 75mm.
Did Lomo make Diopters for all these lenses? What is the exact front filter thread for the Roundfronts 50mm and 75mm (I guess they are the same what I can see...).
I like to have some alternatives for big matteboxes and 6x6 filters..

This was square body with glass inside, install to front side of len's body.
If you see of your lens, you can see a few distance scales on focus ring.
The one, white digitals - distances without front attachment, minimum distance of focusing 1,5m
The second, green digitals - with front attachment( marking 1.0m) with minimum distance of focusing 1.0m
The third scale with red digitals - with front attachment ( marking 0.5m ) and minimum distance of focusing 0,5m.
About 35 BAS LOMO anamorphic lenses with round front glass, sorry, i don't know original diopters.
But, a few years ago, we had special front attachment on 150 mm 35 BAS-2-2 lens and shoot with minimum distance 0,15m.
I think, you can use any other brand name diopters with similar diameter.

what about split diopters? Did the Russians make split diopters and if so I would imagine they are rare as I have never seen one and I look for Kinor stuff quite often.
You mean special front optical attachment for dual planes shooting ?( Trick effects ).
The russian name of set 20C-37 included 5 pcs diopters for distances 0.5, 0.6, 0.7, 0.8, 1.0 m.
This is diopters use for russian anamorphic lenses 35 NAS-4,( 50 mm, 75 mm ) and 35NAS-10 ( 35 mm )but, can be use with any other optical system.
This is hald of spherical glass ( diopters), inside special holder.
The Roundfront anamorphic´s 35mm, 50mm and 75mm don't have front thread.
You can attach of front attachment over of a outside diameter of front part of lens.
The outside diameter of front side of Roundfront anamorphic´s
35BAS 27-1 35 mm - 140 mm
35BAS 22-1 50 mm -105 mm
35BAS 23-1 75 mm- 105 mm
