DIY Camera Lens

[@MichaelMa]

I think this is less of a DIY and more of an expert craftsman with decades of experience doing something amazing.

[@LongTran-yv2nq]

Do it yourself - after decades of practicing

[@aserta]

Well, not really. I tried my hand at lens making in high school. My art teacher had an exposition and part of the set was a ton of lenses he gathered over the years. I captured a few of the big ones and did just about the same thing he does. So that's simple (but not cheap, i spent two summer's worth of savings, and half a year's time to make the two i made, funny enough, i never did anything with them). As for the lathe work, well, aside from knowing your speeds and feeds, and having a lathe that can cut metric, miniature threads, it's not really black magic. NOW, that's not to say it's not hard, some aspects (like lens knowledge after you've made it, or how to design it) are hard, and require a lot of page turning, but seriously, it's not something outside the realm of someone with some cash and time to spend every weekend. Mind you, people have been making telescopes from scratch for decades now. And arguably, those can be a bit more complicated, both in scope, size, and knowledge. So it's not much about experience, rather...how willing you are to meet the demand half way. FYI, he does have some mistakes in the lens cutting, something i learnt the hard way, where he got lucky. You don't leave a live edge on them, and you don't cut them with such a rigid setup. Evidenced by the chips present. On bad days, you can flake the whole surface, something i've seen happen to a few bloggers.

[@mickcard7293]

Hahaha yeah! 100%

[@ff-qf1th]

@@aserta what is a "live edge"?

[@BboyKeny]

​​@@ff-qf1thI assumed he meant a sharp edge. But might be incorrect

[@xn0funx]

Sir, You deserve so much respect.

[@kilohn]

Fantastic video. As an optical engineer, I knew I would have loved to learn the art of lens making, as soon as I met some of the passionate people praticing it. This is a wonderful opportunity to share my awe with my friends. Thank you for this!

[@keynonketcher1525]

kilohn can you suggest which lens to choose for making projector lens

[@Nighthawkinlight]

Beautiful. It looks like you made your lens grinding machines yourself as well? I find that even more interesting than the finished lens!

[@matswernersson8781]

The grinding and polishing machine is really simple to make. This type is called the Zeiss grinding machine. My lathe and mill are from Sherline. They are small affordable hobby machines. I'm using bisquit cutters covered with diamond powder to cut the blanks and to generate the approximate curves. The whole set of cutters can be purchased from China for about $10.

[@Drollfilms]

is it possible to make an anamorphic lense with this?

[@OktoPutsch]

@Natsbert : just calculate its optic and you can make it.

[@eliezermexicanimation]

@@matswernersson8781 haver you ever made anamorphic lens?

[@ScandzaVaeringjar]

I know how to boil eggs tho.

[@matswernersson8781]

Please tell me how. I burned mine

[@vizhakraho]

we're all proud of you!.

[@KeithSelmes]

My eggs boiled dry and exploded. Makes a noise like an electrical fuse blowing. (Don't ask how I know what fuses blowing sound like)

[@primecontent]

ahaha!

[@MetalSlugzMaster]

My goodness...you literally made everything. I don't think there's anyone else that's come close to doing this, at least here on YT.

[@SCM]

good to know that after the zombie-apocalypse someone still can make new lenses ;). truly amazing job!

[@inqinst1323]

Exactly my thoughts

Moon Seongmu who is to take photographs of all the beautiful zombies? 😞

[@bradjohnson9671]

Mats, I have to say this is one of the most bad assed projects I've ever seen on the interwebs. Hats off to you for sure! Absolutely a DIY project. It's amazing what you can do with a small lathe and mill. Go slow and take your time and use sharp tools! There is a reason they call the metal lathe the "King of machine tools". So many different skills and disciplines used for this project. I love the way you scrounged the materials and reused other bits (the aperture leaves), I'll bet you have a pile of old lenses that are missing some screws too.... Well done sir!

[@mikeno62]

That’s just amazing to see how you made the lens elements and all the other components, I really like the way the lens renders the image. What a great video it is.

[@CaptDicker]

Exceptional quality and craftmanship, this is why I have no problem paying $650 or more for a $1200 lens, no way I could make the lens for less than I could purchase one.

[@Mart77]

I was quite skeptical the whole way through but the last photo absolutely changed my mind. Very well done mate!

[@longde]

As a lens collecting nerd, dissasembling them for service, and obsessing over lens designs and differences between versions of the same lens, I SALUTE YOU, this was amazing, particularly the last part where the mechanical assembly was done, complete with fitting the diaphragm leaves and a nice ball bearing mechanism. The only thing missing was coating the lens surfaces by vapor deposition, are you planning to coat your lenses in the future? Cheers

[@garetclaborn]

I looked so hard for anything even resembling diy lens and finally found this. thanks so much . now i just have to wonder, could it work with just some glass made of beach sand on a deserted island xD

It's so beautiful to see how you built it ✨ the images are stunning, thank you ! Cheers from France

[@salian1531]

What's happening at 0:32 onwards? Looks like concave curve generation using a sine table at first sight, but the bottom disk isn't rotating, and then the next screen shows a lens with two convex surfaces which you then block with some green ... pitch? Would be super helpful if you could post something about the process. Thanks for the amazing video.

[@tomreeves5791]

Absolutely astonishing but come on! This is no DIY project. Outstanding that someone can do this at home but as someone else posted, this is a master craftsman ... not a guy with a garage full of tools. Excellent work.

[@kevinli6502]

That is so awesome! I know lenses are hard to make but for some reason this makes it feel more down to earth than I first imagined.

[@TC-rv6sz]

Man, after watching this incredible process, I'm never going to complain about not having autofocus again 😫✋️🙏 Awe-inspiring video. Thank you for sharing ❤

[@jroseme]

Holy smokes, this is the real deal! That video shot looked great.

[@psef87]

I love it. What a masterpiece and craftmanship. You must be a wizard!

[@KhoaNguyen-rk9dz]

Outstanding! The final product looked like a true factory made lens, rather a DIY product!

[@SyanArtStation]

Now I understand why the lens are so expensive..

[@tor9885]

No, it’s because pure optimization

[@ToBeIsWasWere]

What? Commercial lenses are not hand crafted one by one. Also lenses like this are dirt cheap on ebay, you can get them for undeer 30$.

[@zaydabbas1609]

They're easily manufactured all by machine, but it's the calibration and fine tuning that makes them cost so much.

[@RedForShort]

And that lens doesn't include electronics, motors or firmware either!

[@omermagen824]

The dude freaking made a lens. Just like that. Respect.

[@ronysetiawan7184]

one of the most untouchable technology for newbie .. exclusive and very expensive .. we can only watch, without being able to practice it .. but many thank's, this a bit cures my curiosity :)

[@RobinGuymer-Gizz]

A truly remarkable piece of home engineering. Just awesome Mats.

[@sirpablo]

That's one of the best bokeh i ever seen.

[@h7opolo]

great editing and filming and craftsmanship resulting in clear images with an artisanal arcing distortion effect.

[@BrianMoore-gp8ot]

Your grinding jig linkage thing is neat!

[@ditarf85]

I'm completely blown away!

[@Novak596]

Dude that lens came out so clean looking 🤩 well done! I was wowed the whole time 😮

[@photonforager]

This is amazing. If you ever do a more step by step version I would be very interested. I just finished a course in optical design, so seeing this was pretty enlightening for how really works. Great job!

[@photonforager]

Also, how could you tell that you would get the swirly bokeh in zemax? Is it some kind of purposeful aberration?

[@matswernersson8781]

ryan galloway I payed special attention to spot diagrams. Aiming for elliptical spots (tangential) at defocusing on the plus side of the focal plane. On the minus side the effect is sagittal like exploding outwards from the center. It is of course astigmatism with a sponful of coma that makes it. But it is difficult to visualize what it will look like. Whish I had Zemax, I just have the Oslo light that is restricted by the number if surfaces

[@photonforager]

Mats Wernersson, thanks for the reply! Okay so a bit of coma and astigmatism. I still have zemax from a school license, but I'll have to switch to the trial Oslo soon. If you ever make a video explaining how to make a lens in more detail I would be very interested. Again, great work!

[@MaxGarrett]

I've been thinking of trying to make a camera lens for 'lo fi' cinematography - and this has been very inspiring!

[@xolarwind]

UNREAL! What talent!!

[@dansv9778]

Can you list all the machines you need to create the lens please ?🙏 We will love and be a lot more if you start making tutorials on this

[@CiaccheAzzione]

i would love to know that too!

[@VGScreens]

This is incredible.

[@frame_by_frame]

Fantastic, what a cool set of machines.

[@syeedmohammeduzzalhossain5452]

I'm blown away, man. Respect!

[@meadsource]

I came here from a Corridor Digital video (called "the paper challenge") that had this video linked in the end credits. You've impressed someone over there!

[@Aussieeeee]

GIVE THIS MAN A MEDAL!!! Great Job, I pulled apart my L series lens once and was amazed by how much goes into them. Was interesting to see a lens be built! Disclaimer: DO NOT EVER PULL YOUR LENS APART UNLESS YOU WANT TO THROW IT AWAY - Learned that the hard way.

[@JasonRennie]

No need, he can make one himself!

[@Aussieeeee]

Haha probably

[@gewurzbonon9039]

Mats your work is super impressive. Thanks for sharing!

Now THAT is a DIY camera lens 👏👏good on ye

[@SeanHodgins]

Incredible!

[@boogerking7411]

Is that phospate coating? And how did you paint those letters/marking?

[@sajidullah]

Too much talent here

[@CiaccheAzzione]

This is the coolest thing i have ever seen related to photography. After hard searching i finally found something that makes you see the actual process of creating a camera lens. I want to try so hard to do this myself! The only thing is i'm broke lol and i don't know where to get all these materials, if only you could provide a step-by-step guide! i'll make a statue to your person!!!!

[@4trait]

Simply inspiring, creating lenses or optical designs is an art in itself. I consume this type of content a lot and I try to make my own lenses with the remains of broken lenses or binoculars and telescopes (basically anything that has a lens), but my biggest challenge is having access to an optical project, do you know where I can find it?

[@maximilianlindner]

I can't even tighten my shoestrings properly, but you just made yourself a FREAKING LENS :0 Great job man!

[@smallelephant_og]

cool distortion. adds a nice lo fi vibe

[@awsomegamer2775]

Awsome man. Hats off :)

[@AnimeshBis]

nothing short of brilliant!

[@destroyer-yi3uc]

That was so awesome.

[@ghiassie]

Yes, really DIY!!! Because everyone has at least one or two set of these machines at home!!!

[@laurenceliu794]

Hi, I am looking at converting some lens and just wondering how did you manage to etch the numbers and letters into the barrel? Thanks

[@Jkauppa]

try molten glass/plastic spin casting, lower melting temperature for plastic, liquid form essential
