    Early test single focus for 35NAP family. (35NAP 2-2 | Helios 44-2 F:2 | Sony A6300) At the moment, there was a test of possibility of a single focus on these large lenses. The test is done on small lenses, large diameter lenses will be manufactured. Sorry for jitter, pic of DIY body for single below :grimace: And question, my friends -  how do you think, you need a single focus for 35NAP family, these large lenses?

    2M - this is not in real life. 35NAP family - 2-2, 2-3, 2-4, 2-3M. 2-3, 2-3M bigger and heavier than 2-2, 2-4. Optic scheme the same, image look similar. 2-2, 2-4 looks a little sharper, but if good aligned lenses, all will be good. minimum focus distance, if not modded - 8-10 m. If modded, starts from 35-40 cm, but I recommend to shoot from 1m. to close focus - little squeeze. Also present 35NAP 1-1, but I didn't come across.

    What of those 35NAP is better for modding?

    Is the last number (3M, 2M) the minimun focus distance?

    ok. How is your name?

    А кто тогда Миша? Ладно, в самом деле не хочется бодаться. У Крамара на самом деле со всеми терки, кто задает неудобные вопросы. Не знаю, уж ты-то должен видеть. Как частный случай побаловаться разве что. Good luck!

    p.s. Sorry for all for writing in Russian, now all will be only in English. From me not negativity, but the right questions. I really think, that this solution not so usable and have too many cons. I have over experience with that huge Ana to talk about it. My thread about 35nap also on EOSHD.

    bzpop, don't compare John Barlow and this man ))) he just get lenses from body like any other. Many people rehouse 35nap in ex-USSR. You also can do this. You really want to use this setup? Curious to see. You have a skills, I know. This man positioned himself as producer, ok. I don't try to sell, I talk about all what I do. His solution...hmmm. To many cons for me. Heavy, bulky, slow focus with breathing, fix squeeze factor on post, noise from engines, nuclear station for power (joke, haha)... Enough?.. Rectilux beat all this. If all will be good with this system, no problem. Profs - yes, partial solved double focus. How much good this work and how good aligned lenses, we will see after good footages. Федя, зря ты так. Ты ж разбираешься в видеосъемке, у тебя есть нормальный сетап, просто добавь оптический сингл. Да, я не разобрался, кто ты такой, просто в тот момент, когда ты запостил инфу про Крамара, у нас с ним в разгаре были баталии. Человек просто не умеет признавать ошибки, как же, ему надо быть непререкаемым авторитетом. Да, ему надо отдать должное, в чем-то он молодец. Но пока я не вижу плюсов в этом решении. Ну да, как-то переводится фокус. Остальное перевешивает этот плюс. Посмотрим, насколько хорошо он справится в этот раз.

    Он и здесь наследил, Миша, а так чтоб никого не обсирать, не умеешь?

    yeah Dr Verbel, your design rocks! everybody else sucks :) ) )

    i agree,  and don't share "Dr. Verbel's" negativity, the more people  trying to do any kind of research and development in anamorphic glass area  - the better for filmmakers,

    people like John Barlow and Andrey Kramar, inventor of PAS SINGLE,   trying to bring affordable anamorphic solutions to us,  indie operators.

    total respect and best of luck!

    I had a discussion with this man earlier, he talked about working aperture for good focus 5.6 for 35NAP family. But it not true. 35NAP no impact on the final critical sharpness of taking lens, if lenses of this ana well aligned. And he didn't want to admit his mistake. So I set up a few critical. No problem, man creating something, we will see now, he fix problem with sharpness or no.

    Для камер с полным кадром, насадки 35НАП2-3м и объективами 85мм
    на открытых диафрагмах резкости нет (без особых условий освещенности на объекте. см. комментарий)!
    Хороший фокус начинается с диафрагмы 5.6.
    Рабочий фокус при диафрагме - 8

    You guys are so negative. I think he's created something cool that I could not do, which he will probably improve upon. Give him some encouragement, not so much negativity!

    I wrote about it (for one taking lens). Yes, I know. But mistakes of construction (for example, bad aligned lenses) will affect on the final result. Yet I don't see from you any good samples, that's all. Ok, will waiting for good footage on wide open. Preferred the same as other sample, starts from 1.4. Maybe raw unprocessed footage also. Good luck, man!

    In this system it is possible to use only one lens In my system any! It's a big difference. All NAP shoot wide open exactly the same, and you know it!))

    My tests show how the focus, and later I will make tests at different apertures.

    Looks nice, I agree. But how good in practice, don't sure. Yes, I speak Russian

    Very clever. Looks good. Dr. Verbel', do you speak Russian?

    Test from other man with similar method on F:1.4. Quick focus from one object to other. Maded for one taking lens, but more elegant scheme for my opinion.

    Looks nice, but too bulky and complicated, man. Too many unnecessary details that make their error in the final result. Focusing attachments like Rectilux give more convenience, it is a pity that while there are no such large to fit with that huge ana. Cons - changing squeeze factor, when focusing, too slow focus from one object to other. Some good footage from wide open aperture, for example, F:2 or wider? I shooted earlier short test. Do you shoot like this from your construction?

    Thanks! Yet double focus, now I waiting for big focusing lenses. Focusing method of current setup

    XecKbgnHOKM.jpg

     

    With some skills time to capture focus in my case around 10 sec max. Minimum config now is two lenses in 3D-printed frames. Bellows can be added also.

    You can make for yourself, buy this cheap lens on ebay (look for good condition), info of rehousing and drawings for 35NAP 2-3M here https://www.facebook.com/groups/verbascope/ If some additional questions, please welcome to PM.

    This is fantastic work - some great looking images. 

    How difficult is it to work with? Would love to try this out on some narrative projects. Are you selling these?
