Manker developed a Zoom with NO MOVING PARTS (updated info)

That’s my guess too, similar to the film used here:

I’d love to see a patent on this light.

M4DM4X says it does not use a motor as far as he knows.

I saw these videos a few days ago. Time will tell what they are doing, and if it is a practical/useful solution or just a gimmick.

nice……

Telephoto lens concept which has been around for decades.

i like it

no dust and better weather seal :smiley:

The only way to have no moving parts would be using that smart glass or some sort of dlp to change how the light scatters.
Even then there is still technically something moving, it’s just very very small.

It may switch between different emitters/optics like some Energizer lights?
Or maybe an internal moving lens (as per some camera lenses)?

Intriguing design indeed.

Would be happy to see this with Samsung LH351C or LH351D.

A COB that different parts are lit as the beam changes?

Ring COB/ angel eye LED array surrounding a central focused TIR/ reflectored LED with a dual channel driver maybe.

Liquid lens is the future, the shape of the lens can be changed with electrostatic pressure.

Any more info on this M4D M4X? I am very interested in this and I think others are as well. An adjustable beam width light that is optically efficient and has good beam quality would be popular I think. Maybe there is an LED lenser style light that has these characteristics, but the couple moddable ones I’ve seen lately have bad beam quality (like the Litesam E11Z).

Very interesting, can’t wait for teardown

And I can bet you will win in this “guess what” challenge. :beer: That Edmuntonoptics liquid lens at 400$ price but possible someone got cheaper deal elsewhere in China…

Fascinating technology! Although F 2.4 numbers are really not something to brag with. The lower F stop the more light it gathers.

So this technology maybe is still not the best for night vision settings… But! when combined with high quality laser VCSEL illumination and average night vision FHD camera sensor can give astonishing camera results.

Flashlight use…

Well I am not Enderman but I surely see from the video that this flashlight lacks performance vise. Simple T20 flashlight(38mm aspherics) would killed it performance/max lux/flood for sure, and not to mention larger 50mm aspherical lights…

But! If this will be combined with laser light than that will be different story. This could easily become light that in a small form factor (30-40mm head) could easily throw 500+ kcd and have very good flood mode.

It has potential for sure! We are looking at the future.

Bravo Manker!

Pretty sure they said only single emitter and no moving parts, internal or external.

That Endmunds lens looks neat.
I’ve seen Optotune lens before and Edmunds seems way more mature.

Given the high price of liquid lenses, I guess it would mostly bound to high-end imaging applications for now, such as night vision.

Seeing its use in flashlight applications (if I guessed correctly) is a surprise, maybe illumination tasks are more forgiving than imaging tasks in terms of lens requirements, which translates to cheaper lens.

But the size of that flashlight in the video, eergh, too large. If someday, the thickness of the lens module can be reduced enough for mobile phone camera applications, then we can have pocket flooder&thrower at the size of Emisar D4.

I doubt it’s the liquid lens because the beam did not look like a lens beam (no die projection), and manker’s tech has supposedly better light collection efficiency than a simple lens (from M4D M4X description).

Well lenses does not necessarily have to project clear die projection. With combination of different kind of precoolimator lenses/diffusers, different distance from emitter you can get different shapes of beam but that usually means sacrificing of lux performance. We had such lights before(but with manually zooming mechanism)… Forgot model name but they had circular beam for the guys who thinks that nice old square die projection sucks :slight_smile: , so they were apparently happier with lower lux performance lights but the most important it has circular beam :smiley:

“Manker’s tech has supposedly better light collection efficiency than a simple lens (from M4D M4X description)” Well from mine personal experience of just watching attached video i would not say it has better efficiency than single moving lens system…

I personally did zoomie flashlights out of camera lenses which in fact are multiple aspherical lens systems, and while beam looked great performance vise they were always beaten by single aspherical system. They are only good as IR host.

We will follow this thread and see :wink:

I doubt they are using something exotic or groundbreaking. Probably something has been lost in translation. I expect there will be a “catch” and the truth will be less exciting than the promise. But I would love to be wrong.

This seems likely also.
All the Best,
