Poor man's deakinizer (20 replies and 22 comments)

Hi everyone!

I am going to shoot a music video and I'd like to try something like deakinizer,a custom lens made specially for Roger's The Assassination...film.

If I've got the idea,the original system is a particular combination of an old-fasioned wide lens' front element and a modern macro lens.Generally you've got an image with all these beautiful aberrations and just capture it from the surface of front element with the macro.

But it seems to be too expensive to disassemble a lens for sake of single use...

Does anybody have an idea how to replace front element? Kind of loupe?

Thanks a lot for your answers

It usually isn't hard to take apart one lens or assemble it, as long as you're properly trained.
But swapping out front glass from one specific lens with another (brand), will, in most cases, give you a headache.
What kind of lenses are you trying to combine ?

I've had success with large old stills photography enlarging lenses and also lenses used on Rostrum cameras. Best mount was using an adjustable bellows froman 8x10 camera infront of the Motion picture taking lens.

could you please share a sample image here?

right now I am collecting information and do not have any idea which lenses should fit exactly,that's why I am asking you here)

Macro lens should be Arri Macro 60 or something similar,the question is what kind of front element should it be?

Maybe I'd better try a vintage fisheye like following

?

Enlarging lens is a good idea,you mean I have to fix it on a large format camera lens deck and use its bellows to adjust focus and tilt/shift?

Yes exactly the bellows allows shift tilt to taste on a shot by shot basis. BTW have you seen a Lensbaby? I have a director pal who swears by hers. http://store.lensbaby.com/optics/» Mind you she shoots low budget commericals on a Canon 5D

yeah of cause I know about Lensbaby and I am going to combine deakinizer shots with lensbaby PL and Arri Tilt and Shift)

You do not need to use a macro lens for this effect. In the past I would use a 50mm with an element from an wide angle Soligor stills lens to create the effect.

Great! thank you Roger! I thought about macro 'cause some of existing original deakinizers at Otto Nemenz rental are front element plus macro set up,am I right?

And,again,my point is are there any possibilities to get the gig without disassembling a professional cine lens (for budget reasons)?

And if I'd got a wide front element somehow and a plain 50mm,I have to put the element right in front of my lens,utilizing it like a filter or a diopter,or I'd have to fugure out how to build  a fixture to move it closerfurther along the optical axis?

but if it is a cheap still lens like Soligor 28 M42 and it fits , then it's worth it!

Perhaps the originals are Macro lenses. I was using them the other day for some tests but didn't notice! Shows how observant I am! Nonetheless, I did the same effect with a standard 50mm and an old lens element. I wonder if you could use an aspheron lens.

Never heard of these till Roger just mentioned them. This is really interesting.

The article says at the end that if you try to use it with the mk 12mm, you'll get spherical and chromatic aborations.

Thank you guys!

Maybe I'd try some still wide angle lens or converter.

If I will find the best way to achieve the look I will surely share screenshots and description her!

Or maybe I am to try to buy an old medium format still camera with wide angle and bellows at a flea market and will try to deal with it...

UPDATE
I'VE GOT SOME STILL DEAKINIZERS FINALLY!!
I have taken an old Mir 1B 37/2.8 and Helios 44 58/2 soviet m42 still lenses tried to remove front elements,but after this I could not achieve focus anywhere,so I tried simply reverse front elements convex side inside and now I have got similar effect!
Right now I am waiting for m42/pl adapter to figure out the possibility of the lenses with Alexa.

here are some stills

very nice ! very interesting . Could you detail the modification you did on those lens ?

mindscrapper

I just asked the engineer to unscrew the front element , turn it concave side out and screw back into the lens barrel and that is it!)

here is an example of low cost Mir 1B lens
the main problem to solve is how to place it into a PL adapter because of its diameter....

You just switched around the front lens element? I think I'll give that a try, albeit with a different type of lens, so hopefully I might get something similar. Beautiful photographs! Very very cool!

mindscrapper

Yeah correct!
Just switch it around and enjoy!)
Works better with wide angle lenses

Those are really beautiful images! I think I need one of those lenses!

mindscrapper

Oh really? Nothing is easier!
but you could not place it into an existing m42/pl adapter to use it for cinematography because of diameter of the lens barrel that is more than inner diameter of adapters.
The guy from http://www.rareadapters.com» promised me to design an adapter with thinner walls made of harder allow but who knows how much time will it take!...

Do you presume they used a similar set up for the final shot of The Revenant of Leo?
