Photography lenses rehoused

PostSat Nov 20, 2021 1:26 pm

I’ve been looking at the Tokina Cinema zoom lenses. Especially the 11-20mm.
What I came across in my research was interesting.

The atx-i 11-20mm F2.8 CF photography lens has virtually the same specs, optically speaking.
However there’s a massive price difference. Is the only difference the Build material, PL mount and of course it’s change in focus throw, due to the size difference of the housing.

As far as I can tell that’s the difference, they should produce the same image.

Still & cine version have the same glass and image quality.
Youtubers like joey helms, threefold , driven films was actually agree with that and I have confirmation email from Tokina USA representative.

I was wondering how can I find 3d print file for focus ring of the still version?

I’d love to cine mod my old Minolta glass. But I haven’t done it. Part of it is that I would want to go PL Mount and that’s a very expensive process due to the increased difficulty.

I only use manual Cine lenses. One advantage is the common placement of the gears so that it can be quick to change lenses say from the 11-20mm to the 25-75mm. The tension in the gears is likely better adjusted and there may be more attention to colour matching the lenses. The materials in the housing may be better with Cine lenses using more metal or all metal. The markings may be better in terms of visibility, colour, and quantity. And usually the focus throw of course permitting safer focus.

I think there’s a lot that goes into the making and operation of the Cine lenses, but that doesn’t mean the photo lenses can’t also produce good images too.

Tokina puts quality lens elements in their photographic lenses. There are variations in the production of lens elements, and a mass produced lens made for a low price lacks the laborous matching of elements that is done by hand in a quality cine lens.

Several years ago, Matt Duclos made a reputation with his Cine-Mod conversions of the Tokina 11-16 lens. He did this by cherry picking the lens elements from several lenses, and he redesigned and made a new focus and zoom system, with a lens housing, retaining the original lens focus scale. Lens and zoom gears were then fitted. It weighed about twice what the new ones weigh, and is parfocal.

Before Tokina made a cinema 11-16 lens, this re-housed parafocal version of the Tokina 11-16 came out. It generally sells for $1200-$1500 USD used:

"...Still photo lenses, even those that are widely-used for cinematography on DSLRs, have electronically adjustable settings, which means some settings (like the aperture and focus) are changed with a press of a button or a slide of a ring, sometimes via a menu on the camera’s screen."

Thingiverse is good source for modifying existing work and there’s a gears tool in Blender that will do the job from scratch.

Good Luck

But as that email notes, only the cinema version is parfocal. The stills version is not. That's not a trivial difference. It makes paying for the cinema version worth the cost difference.

Thank you for adding that, Jamie. That’s pretty much the number one reason to use a Cine zoom over a photography zoom which should really be called variable prime lenses. Some cameras may appear to use parfocal lenses but that may be due to the camera correcting the problem by making other adjustments for the shot.

Thanks for taking the time with all your responses everyone.

I definitely see the benefits in going cine, that parfocal is a massive plus.

I think I’ve decided to go cine!

I was after something that would possibly be a step up from the DZO PICTORS.
I was hoping perhaps the Tokina might be those lenses.

I’m still going APO hypers for my prime choice.

Well, DZOFilm did just release the new DZOFilm Catta lenses:

Re: parafocal. Since I mentioned Nikkor lenses I should have added that not being parafocal is a significant issue. From all I have read and tested the only parafocals are the 70-200 (which is favorite of mine for my work) and its predecessor the 80-200, which has an aperture ring. If there are others correct me.

Guys can you explain me what's the difference between?
Tokina Atx-i 11-20mm F2.8 CF
Tokina Atx-Pro DX 11-20mm F2.8

And which one have the same glass as Tokina Cine 11-20mm version?

You can look at reviews on the internet. It may be the Pro version is older and no longer available. One review mentioned a noisy motor not suitable for video. These lenses may exhibit more breathing or other artifacts than the Cine version.
