Conversion LOMO Anamorphic roundfront F = 100/2.8 , on Superspeed lens F = 100 /2.0

[Sergey Kravchenco]

Hi !
Now our optician made conversion anamorphic lens 35BAS25 - 2 , F = 100/2.8 , T = 3.4 - will replace optical block on another OKC1-100-1 , F = 100/2.0 , T = 2.3 and lens will more faster ..
Optical block OKC1-100-1 T=2 more about 10 mm in diameter then optical block OKC2-100-2 which fitted on rear part ( submount ) of original anamorphic lens 35BAS25-2 , therefore it is not possible only replace one optical block to another . Now our optician made new submount ( rear part ) from hard black anodized aluminum ( it more large in diameter then regular anamorphic lens 35BAS25 - 2 ) , new iris ring with new engraving , new anamorphic lens F = 100 /2.0 will has T=2.3 .After lens carefully collimated .
If you want to convert your lens on more faster – price of conversion $ 1900 .
And the same conversion it is possible to make from LOMO roundfront anamorphic lenses :
F = 50 /2.0 type 35BAS22 – 1 and F = 75 /2.0 type 35BAS23 – 2 – this type of lenses has absolutely equal front anamorphic part – difference only in rear part with prime lens and with this front anamorphic part it is possible to made else some anamorphic lenses F = 135/2.8 and F = 150 / 2.8 – I have bought some lenses and buyers was very happy .
Now our opticians finish work for conversion LOMO anamorphic F = 35/2.5 type 35BAS27 – 1 , was made new rear part and fitted in it Superspeed block OKC12 – 35 – 1 , F = 35/1.4 now lens has F = 35/1.8 and it is the same conversion make for lens 35BAS22 – 1 , F = 50 /2 and 35BAS23 – 2 , F = 75 /2 – replaced prime lenses with standard speed on block of prime lenses superspeed .

If you want to order conversion your LOMO roundfront anamorphic lens :
35BAS27 - 1 , F = 35 /2.5 on superspeed F = 35/1.4 , T= 1.8
35BAS22 - 1 , F = 50/2 on superspeed F = 50/1.2 , T = 1.5
35BAS23 - 2 , F = 75/2 on superspeed F = 75/1.4 , T = 1.7
35BAS25 - 2 , F = 100/2.8 on superspeed F = 100/2 , T = 2.3

P.S. - the price of ready Superspeed lenses from me $ 4900 + shipp.

He changed the back group in the lens so that you get more speed. There can be some issues with Vignetting at the edges of the frame, and maybe a little more softness at the wider full open.

Anamorphic lenses need to have their backfocus set just right, and the bigger the f/stop opening the harder it is to get that backfocus just right, as well as to align all the elements, but in theory you could get a better T/ stop in the center of the frame, and so get better exposure even if the images are not quite as sharp as before conversion. At the same T/ stop as before the results should be about the same, or maybe a little better, that is if you shot with the old 35mm at T/4 and the converted 35mm at T/4 then it might be a little sharper because the faster group might be better corrected do to the extra elements, perhaps, you would need before and after shots to find out...

Hi!
Lens full cover format 35 mm without any vignetting in the edges .Next week I shall test lens on Optica Elite and shall write results on forum .

Best regards

Hi Sergey,

Hope you're well!

I just want to check, that when you say the lenses cover 35mm frame do you mean they cover the Full Frame 35mm frame? If the optical block is from a lomo designed for Super35 will these lenses cover Full Frame 35 (as anamorphic should) and the upcoming Red FF35 cameras?

Thanks dude!

Hi Ben !
I am tested after conversion anamorphic lens F = 100/2.0 on OPtica Elite with projector and the lens has the next results - lens F = 100/2.0 full cover format Super 35 - 1.33 ( full aperture - 24x18 mm ) , visual resolving power - 120 / 75 ( lines in mm )
