Hi!

I am developing a new lens for DSRL,

It's a 55mm f2.0 with 4 elements in 2 groups, the body will be made of aluminium with a 1080° focus ring and a maximum magnification of 1:2

I am testing with a Canon 60D, but I will try get a better camera in the future.

Very cool. Is this your own design?
>>

Why does your exif say 50mm? How are you able to make a lens? Are you an engineer for an optics company? Why not mirrorless? Seems that's where things are going weather you like it or not.

Is based on a design from1866 by John Henry Dallmeyer.

-The exif say 50mm because that is the default number when no lens is detected.
-I buy the lenses from a chinese factory, I am trying to souce someting in my country. Glass making is very complex and expensive.
-I am not an engineer, I am an art student.
-I dont have a mirrorless camera, but it will work in a mirrorless with a pasive adapter.
>>
>>3966857
I would be able to make wider lenses for mirrorless, but I can't test them.

what gearfag level is this?

I don't know, I like history and make new things.
>>
Can you post pictures of the barrel design and the process of putting all together? Thia could be an interesting thread
>>
>>3966854
Cool, where's the lens pic?
>>
>>3966865
Gearfags would never have something custom built

I don't have good Renders, but someting like this.
>>
>>3966871
Current prototype is made with tin cans and some pipe, I don't have a photo here.
>>
Image quality looks pretty shit and I don't see what this offers over any other thrift store 50mm?
>>
>>3966879
He made it as a project. That's what it offers: a neat project
>>
>>3966879

Quality will inprove in the next build, the lenses are a of axis.

>>3966878

(Sorry for the low quality)

beautiful as fuck, anon. Unironically

Hi!

Go fuck yourself you stupid FAGGOT!

sovl

>>3966872
lol how new are you?
>>
>>3966895
What I should have said is: gearfags dont custom build anything. They just throw their money away
>>
>>3966868
very nice 3d pop, beautiful. what is the lens design based off?

no u

>>3966862
how do you learn to build it? also where to buy?
>>
>>3966883
>>3966876
can you made the lens' body with 3d printing?
>>
>>3966883
Cool! With this you can become the next Miroslav Tichy!
>>
>No Nikon F mount
Sad! but keep going, looks very nice actually and the specs are not half bad, 1:2 with 4 elements at f/2 is a Micro-Nikkor/Macro Takumar on art steroids.
>>
Super cool shit, OP. Please keep us updated as your work on it!
>>
>>3966990
I did learn by reading the old patents and a lot of early photography books. Also, I study "Audiovisual Arts" in my local public (100% free) universitiy.
Sadly, no buy date yet.
>>3966991
I did thought about 3D printing it, but it can be done smaller and with better focus with metal. Not a lot more expensive.
>>3967003
It can be made with a F-Mount
>>3967061
Thanks, I will.

It's design based off the Rapid Rectilinear Lens (also called RR) developed by John Henry Dallmeyer in 1866

What're you gonna do for the aperture and focusing?

The focusing is done with a fast multi start screw thread and the aperture with disks with a hole in the front of the lens, sadly a normal aperture is too difficult for me now.

>>3967082
How did you calculate it? I once tried to calculate a better lens for my Fotokor, but it looks like it's easier to invent a cure for all illnesses than to make even a simple lens in Code V
>>
>>3967333
I did some experimentation in WinLens3D, but I don't know the math or the technical stuff.
I did select my glass from a catalog, so the hard math was already done.
But yeah, is can be better with optimized glass.
