Some real world diameter would help I think. To setup these lenses with trial and error wouldn't be easy.

Here's my very first try. The orientation of the lens wasn't right. But you can see that the circle in the back has this uneven dof (getting stronger sideways). I think that this is what will cause the bokeh you meant. As I've seen your Movie i'm not 100% sure anymore. But If it's the right way, i don't think it'll be a easy setup.

All the same mate, well done, that's very cool 8-)
Like you said, it's stretched the wrong way, but at least we can see the beginnings of the Anamorphic effect!

I think you should forget about any projects you may have for a while, and work on those Anamorphics instead :mrgreen:

Some users won't understand the appeal of Anamorphic until they actually see what it can do for their renders. But if they had Anamorphic bokeh in Octane, I think they'd be totally in love with it, I know I am!

Yes I'm a long time real world anamorphic lens fan too, haha.

I already got this effect vertically in an slightly more complex scene, but because I wasn't able to focus anything I gave up and didn't save any render. Maybe I will give it another try. As I said real world lens diameters of an anamorph adapter or something would save a lot of time.

wokaround for now: render without DOF, use AE to make DOF with the help of Zdepth and some glares (let's say wit the help of red giant) - know the path is way longer, but at least You'll get the result.

Haha, yeah, I totally freakin' looooooooove Anamorphic!

I only wish I knew of something I could point you to, some data or whatever, but I can't think of anywhere. There was a time when I was even thinking about making my own Anamorphic lens rig, taking the trick that home cinema enthusiasts use to convert their home projectors to Anamorphic. There are tricks to make them, entirely DIY at home out of prisms. Trouble is I think you might hit the same focus thing you're already hitting using oval glass.

Here's the link to the site but it's not really what you wanted (a very cool page though):

Thought about that sort of thing, but I want it for real in Octane :P

@linvanchene
Seems a popular topic, Anamorphic, doesn't it?

It's one of those things that people who aren't into videography or cinematography don't bother to read about, but once they realise what it is they're like ... whoa ... WTF man ... no wonder it says "Anamorphic Widescreen" on the back of my DVD's and Blu-ray's, now I get it!

Thats when they start demanding Anamophics and the artistic licence to use it on their own stuff, to give it that magic :mrgreen:

think it will come one day. Don't underestimate how much time does it take to code something..OTOY is moving & if they manage to root Octane as production tool for big houses..I'm prety sure we'll see even more serious development, 'cos lot more money stands out there.

Well, I hope you're right!

I'll admit I want it purely for selfish reasons (because it looks so bloody awesome), but if Octane is ever to be composited correctly with movie footage shot through an Anamorphic lens, it's not really an option, it's a necessity - Octane really should have this stuff.

@All
Just found this video, really good because it starts off with example footage of how it makes everything look more grand, then it goes into the options out there, but most importantly, why it looks like it does and why it's a sought after effect.

It's a very good video, well worth a watch, especially those that are curious what Anamorphic is all about:

Hey man, glad to hear you got inspired by it 8-)

Intersting read, only thing I would say is that what you're asking for is effectively 'analogification' of your render, to make it look more organic and less digital. I totally feel your pain and would love to see that sort of thing too; film-grain and matte-glass emulation for example, and yes, dirt, but I doubt it (but who knows). We definitely need a way to adjust the virtual glass we're shooting through, though, and that means control over the lens shape and shutter blades - those are a must otherwise the entire program is no tuch use for matching up to real world lenses properly.

Yup, would be amazing if we had control over that - I want to see "Anamorphic" selectable from a lens drop-down menu :mrgreen:

BTW, found this one on Vimeo a while back. It was shot on a Canon 550D, and wow, what a difference an Anamorphic lens makes to everything. I especially like this one because even though the image has been squeezed back you can still see the Anamorphic tallness to everything, looks absolutely amazing, very Anamophic!

And check out those flares on the cars!

Sheer awesomeness, and BTW, I couldn't get vimeo embedding to work.
