This looks like a perfect job for a script that takes lens specs as an input and produces an object with all geometry and materials set up. And you only need to do it once to be able to make any lens.

As an old cinematographer, I always wondered if you could simulate physically accurate real lenses with a 'normal' 3d application, but I've always been too lazy to try it out for myself. Thank you for sparing me the work! The result is jaw dropping, really out of this world. I'm in awe!

he actually did it, he actually did it, he actually did it

I'd be lying if I said I understood half of what you're doing in this video, but this is genius and I would absolutely pay for an addon if you made one.

Neat video, using a orthographic camera to simulate image plane is a fascinating idea. Since this is tangential to my research topic, here are some things you may consider testing in the future: - Diffraction test. Another famous visual signature of optical artifacts is the sun stars, or diffraction spikes. For the lens modelled here (the 85mm 1.5), diffraction should become relatively obvious at f/22, at which point the entrance pupil is about 3.9mm and the actual diaphragm about 2.4mm. Serenar has a 20 blade aperture so the sun stars would have 20 spikes. Although since blender is not modelled on wave optics, I am not confident in its ability to replicate diffraction. Another application of diffraction would be the coating, since they rely on offset the peak of the waves, but the rendered images already look like they have modern coatings so this probably won't be necessary. - Find ways to introduce CA. The images in the render has some of the 3rd order aberrations but has no CA visible, it is too clean for an uncoated glass using an 1950s optical design. I suspect this is caused by the dispersion not being calculated. Not sure if Blender offers this but another important parameter in the patents, aside from RI, is Abbe Number, sometimes represented as VD or V as in the patent you saw, also inversely corelated to dispersion. If this parameter can be modelled, it should offer a better simulation result with ample CA (besides, doublets kinda become meaningless without Abbe number). - Digital emulsion. Similar to how that other dude tried to model the film spectral response curve, digital sensors have that too. In addition, the digital sensors have several layers of filter in front of them, include the Bayer filter, the microlens, a low-pass, and an UVIR cut, sometimes an additional clear filter for protection. If these are all included, you might find more vignett and color shift in the corner of the image for this Serenar lens. - Mechanical structures and edge of the lens. A lot of the flares come form light reflecting off the interior of the lens chassis or the beveled edges of the lens as total internal reflection, they also tend to cause veiling glare at times. So far the rendered image seems to be free of all these artifacts (there are some dots but I am not sure if they are scene geometry or flares), it'll probably have even more of the "vintage" feel with some flares and glares. But again, dispersion needs to be modelled for the flares to look right.

It's amazing how humankind using just soily the power of math, digits - _imaginary measurement thingies, mind,_ can simulate NOT ONLY the behaviour of light itself but even how this very digital light transfers through just a bunch of mere triangles and shaders with a PHYSICALLY ACCURATE output I have no words, this is truly the greatest Blender video I've seen

I stumbled on this video. Not even in this field of work but my guy the passion and joy comes through in voice and I stayed for the entire thing. Brilliant work

🔥 A Collection of lenses ready to use in a blender addon would be the absolute best. I am 100% sure this would sell great on Blender Market, and i'd be the first to buy. 💰

I'm a photographer, and am VERY much not knowledgeable in the 3D modeling space, but I find this to be so incredibly interesting. Most of the camera/lens renders I have seen online have all been full frame/35mm sensors, and while watching this I could not stop thinking about simulating a medium format sensor, or even simulating a digital large format sensor/lens. Side note, while fast lenses are great, stopping them down to around f4 or even f8 (ESPECIALLY on medium format) achieves stellar photographs. I'm not sure if you stated why aspherical lens elements were difficult to make, I'd like to hear more on that. It would be crazy to try this with anamorphic lens elements as well.

Grate theme! I will try to make some vintage lenses like helios 44m-4, tying to calculate the IOR for them rn. BTW, anyone who have a problem with focusing you camera during tutorial, check the face orientation of your lenses, it has to face outside(being blue). Just spent 2 hours trying to understand why it doesn't work, haha

The tutorial we've all been waiting for!! Amazing work

It looks incredibly good! Looking forward to the next videos in the series!

Holy, what a banger of a video. I loved how you explained the concept AND showed an example of how yo implement it. keep up the good work

I love the way people outsmart software with their own tools. It's very clever - from start to finish and well explained. It should be made into an add-on ! Also: the music transports the whole thing very well together with my alpha brain waves ;D

Now this is going next level in-depth! Awesome!

Dude, I don’t even have blender (yet) and yet this was the most thorough and thoughtful tutorial I have ever seen. The way you took the time to explain everything in precise and understandable detail, to the pure excitement and passion in your voice when accomplishing the unbelievable and being genius enough to teach it…. This shows mastery, and love. Bro thank you so freaking much for this! This singular video might be the single kick I need to finally install blender. I have a Mac book so idk how good it’ll work, but darnet I might have to start saving up for a pc if that’s the only way! But freaking PHENOMENAL!!! Just earned a new subscriber!!!

I watched the original blender camera video you mentioned, and im honestly so insanely excited for where this work can lead us. Thanks fo putting in the work❤️

Thank you for your contribution to the community Zircron. Ive wondered about doing this and actually tried it the same way you did about a year and a half ago. And it worked! But i never wrote it down or did anything out of it because i had no time, its nice to see this actual project going forward, this makes blender be one step closer to being a complete engine for cinematic productions in movies and etc

this is dope zircron!

I've found absolute gold with this video. Thank you so much for being so thorough with this, I've learned a lot from this and you explained it in a way that I was able to emulate another lens as well. You mentioned aspherical and more videos for this topic and I'd love to see those if you ever have the time. The results of this looks so cool and I've been obsessed with emulating film as well so everything surrounding that is just perfect for me. And maybe ways to automate stuff like focusing or exposure would be cool, still figuring out systems for that. But this is super interesting and fun, so thanks a ton for making this video

begging for this was 100% worth it. Thx zirc

Man this is amazing!!! Subscribed, liked this video

This is amazing! I never thought of simulating a lens by recreating it. The results are breathtaking!

Dude this is a banger video. As someone working at a university I'd say your way of showing and teaching is perfect and there is so much to learn. Only thing I might recommend is getting a "key press" add-on in blender so it is easier for everyone to follow and you don't have to worry about forgetting to call out a key press. Keep up the amazing work mate💪

This is one of the most informative and insightful tutorials I've seen for blender. I never knew it could be used like this to setup cameras in such an interesting way. It was a blast to follow along. hahahaha I'm making some more cameras now. I have never known such joy in blender. This is so much fun. Thanks!

This is extremely exciting. Can't wait to give it a try ;). Great work!

This is incredible work and so dense with information, thank you!

I knew it could be done, but I never got around to making the elements. Well done, with the research and the patience and execution!!

Yo Almost 20k Views right now. Its getting the Views it deserved. Well done!

Rare Zircron45 Upload Love your Videos Started with blender again recently.

This is very impressive! Great work!

Great video, and the results look incredible! Great job

This is brilliant work. Keep doing what you are doing.

Finally ! Thanks for sharing your wisdom.

Awesome and stunning work!

This is awesome bro super cool work

Fantastic! Thank you so much for sharing this knowledge!

Mindblowing stuff, thanks for sharing this is insane!!

Just rewatched the old intros you made 7 years ago for me(Twisty Mccheezy) and it's incredible how much you've improved! Not only in blender but I can't imagine how long it took to record and edit this video! I sometimes find myself reminiscing about the days when i was like 12-13 and made intros all day. You were my most loyal subscriber and I want to thank you for giving me motivation when needed it the most (even though you probably didn't know you did. I wish you the best and hope you get successful doing this.

Amazing , can't wait for the next episode

Nice job! I did this for the meme, but I'm impressed with how you've managed to refine it. I'm also really curious about why that DOF trick of the orthographic camera ends up allowing you to get the focused image in the end. (Thanks for the shoutout ^^)

mind blown, thank you, just an amazing tutorial

Dammmmn this is such a soothing video. The music adds so much to the atmosspere and i am so hooked watching the whole thing

HOLY MOLY i am amazed by the clarity of the tutorial, thank you good sir for sharing your knowledge

The video is incredible… and that path tracing is so good, that this is even possible. Mind blowing

Literally a month ago I tried to do something similar, although without the exact optical diagrams. Glad to see your video! Amazing.

Amazing work!! Congrats 🎉

the results are amazing dude, commenting for the algorithm

This is so insane! thanks for sharing your big brain!

This right here is fire! Please do keep going with this. Would definitely like to see an odd-on of this kind too.

Incredible work Zircron45! I look forward to the anamorphic version!

This is one of the coolest videos I've seen

Great work! will enjoy utilising this with my other artistic filters and effects i've explored over the last couple years.

This will be getting a million views and probably tens of thousands of subs from this alone 👏 👏 👏

This is one of the coolest videos I've seen for 3D / Photography. Keep up the awesome work, and get a pateron or gumroad so we can buy the lenses you put out ;)

truly incredible work, here.

man! thank you a lot for the tip with the ALT key and multiple object lol) besides that love your video, it's pretty inspiring! keep going!

You did what I always wanted to do! Kudos to you man! Now its time to make some constraints and be able to set all from 1 single panel with a custom addon :)

Insane!!! So good man!

wow! this is amazing

phenomenal work bro ❤

This is absolutely sick!

This is SO INSPIRING!! I do hobby photography and even if they're still a complete mystery to me, I love optics. I'm gonna try replicating my own sigma 50mm f1.4 lens if I find the patent. This is such a cool way of rendering. I'm still a newbie to blender, but want to get better so bad! Thanks for the inspo and great video. Love the vibes you've got going on

Looking forward to these next videos!

that crooked sensor shot at the end blew my mind. awesome project!

this is fantastic, thank you.

Great, great work!! I will sure use it in a lot of projects. I plan to make a seet of lenses cotrolled with riggs to make them functional for animations. Thanks a lot for the detailed information you share. It's very, very valuable.

Awesome Video! Crazy interesting and informative! Great Job! Simply Amazing Stuff!

Absolutely stunning work. Thank you so much for giving out all of this information for free, I greatly appreciate it. I will definitely use this method in product renders and other renders where I need extreme realism. It will definitely remove a bit of compositing work from my pipeline, and look a lot more compelling and “real” than traditional composite methods. Again, I thank you for giving us so much information for free. You are a legend. ✌️

This is amazing!!

This is so cool!

insane video man 😮

One the Craziest 3D related vid I have ever seen I was like what is he doing but all started to make sense from time to time

I don't know why i watched it, it's just pops out in my recommendation, and i glad it did. Really like it

Nice job! With that you can basically use movements as in a large format camera front and rear standard to simulate Scheimpflug rule of focus plane manipulation. I've been thinking about making such thing in Blender years ago, but couldn't. This is neat!

Great work! I tried to something similar a couple of years ago in Blender but the results were so bad that I thought it would never work in practice. Lots of great tips in this video.

wtf bro this is absolutely genius!

This was insane... I don't have words

sick dude much love.

Absolutely amazing! Please give us more

Been decades since the last time I touched any 3D software - I even moved on to photography and other things since then - but this is the video I never knew I needed until now. I think I might actually give Blender a good try with this. Great job!

This was an incredibly insightful video, thanks for sharing! I'd be really interested to see any progress you make on the scripted tool you mentioned in the comments. The results are really beautiful

this is sick. Imagine the render times using this for an animation but damn it would look great

Actually very interesting to learn how an actual lens works! :)

damnn great video man! intresting trick on using inverted orto cam, for sure will try it myself with my fav lenses

I was mind blown!!!

This is amazing!! I want to use that in my projects asap!!

Wow! There is some proper science involved!

I love taking ingame photos in photo mode, and this reminds me of taking pictures in Infamous Second Sun except the depth of field here has a way higher sample count and looks way better and gets cool effects like slight lens distortion, bokeh on particles, etc. I wonder if there would be any way to implement this by a mod into a game based on a blender render of a lens like the one you found on that patent site, if it's legal of course, to avoid getting the mod taken down. I especially loved that in Infamous, you could very carefully adjust the fore- and background DoF and adjust the focus point size and direction. It still holds up in my opinion, but it obviously could be better. Thank you so much for making this video! It's very cool! :p

I tried another patent (specifically Canon FD 50mm f1.4 JP 1995-151965 Example ML) and I cut a hexagon shape into the aperture. looks even better! It surprises me how easy it is and how much you can do with those cameras!! thanks for making this tutorial :D

instant sub. this is unreal

Always wanted to do this, thank you for this knowledge. I will definitely tag you when i make something.

i would love to hear a lens designer’s wild ideas that would only be possible in virtual space

Hey! This is an excellent demonstration. I have done a similar setup myself in the past, using 3ds Max and Corona, however camera/sensor trick didn't come to my mind. Very good idea. I would be interested in seeing a regular camera set with the same parameters and the simulated lens setup. Just to see how much it affects the image quality, and if it would worth the render times.

This deserves more views

Beautiful man

That is the coolest blender video I ever seen

such a fun project!

Fascinating video, thanks for making such a clear explanation. I'd be super interested in how you could model aspherical lenses, since that would open you up to a lot more options. Is it something that would be possible to integrate into the script you and Alaskan FX are making?
