Pieca: A Raspberry Pi Camera System for Leica M Mount Lenses
Вставка
- Опубліковано 16 лип 2024
- This camera project is a culmination of countless hours of learning to code in various languages, design 3D parts, print them successfully, build basic electronic circuits, use optical elements, and solve complex problems in general. So without further ado, I introduce the Pieca Camera System!

This is awesome on so many levels! Great project!
Really enjoyed your explanation, thank you.
You sire, are a legend. This is exactly what I've been looking to do as well, but because of my utter lack of knowledge when it comes to optics - I was trying to solve the problem using common common camera gear. The crop is the biggest issue when it comes to Pi HQ Sensor, and it is imo the biggest issue (software being the next - but atleast that can be worked upon). Not only did you solve it elegantly, it completely made my homebrew solution unnecessary - which was to hack a depth of field adapter and then take macro shots of its projected image. I did come across focal reducers but I still thought that putting a macro tube between the sensor and its lens (C mount or M12) to reduce minimum focus distance, and then put a ground glass/focusing screen in front of it, which was to be placed where the camera sensor/film should be. It's just bulky and massive, and wouldn't fit inside an existing camera body. I couldn't find a speedbooster that would convert 35mm/APSC lens to C mount, but you just made one and documented it so well :')
Thanks a ton, especially for the documentation! As for people suggesting that an old camera or film would do a better job - they're missing the point. A Pi Cam can be whatever you want it to be, and as long as you're willing to write some software, you can also control it however you want. Most cameras come with PASM dials, some have weird interfaces, only Fujifilm and Leica cameras have shutter speed and ISO dials (a few exceptions) but they're pricier than ever. A Pi Cam can be tweaked to have whatever interface, whatever body, and any features on UX side. You can't really buy any other camera sensor for a project with that much freedom.
Thanks! I’m trying to work on a v2 so look out for that (probably not soon though haha) good luck on your pi camera build, always excited for more pi cameras out in the wild :)
Hats off to you!
Amazing job!
Incredible :)
Absolutely brilliant! Highly entertaining video as well. I must be honest, even with Leica glass I was somewhat dubious of the image quality from such a small sensor, but your images at the end of the video spoke for themselves - fantastic! I make my own pinhole cameras with my Glowforge and though I love the analog process I am naturally curious about creating my own digital camera. Unfortunately, there seems to be a savage Raspberry Pi shortage and scalpers are shamelessly robbing the desperate. But if I ever get my hands on a legitimately priced Raspberry Pi, I am sure to refer to your project. Cheers.
Thanks! It’s a pretty small sensor and the images do need some post processing. The pi shortage is crazy you can find some reasonable prices if you get a kit from one of the main distributors. I looked into creating a film camera with my 3d printer but needs to be much more mechanically sound to prevent light leaks.
@@teaandtechtime Thanks for the reply! I'm finding that even the kits are being sold without the pi. There's two options, with or without the pi and the bundled version is always greyed out lol. I'm on all kinds of waiting lists now so hopefully I'll get a shot at one. Makes me wonder if I can do this on an Arduino. There doesn't seem to be a Pi Camera SDK equivalent for the Arduino, so features like focus peaking will be tougher for me to program - if not impossible.
It will be good DIY kit!!
You're a God
Way cool & the photos are nice.👍
Thanks! V2 should be coming out soon :)
Awesome.
Incredible project, I would love to see an update video!
Great picture examples as well.
Working on a v2, video may be a while out though haha
@@teaandtechtime I can understand that! Thanks for taking the time to respond!
cooool!!👍👍
Wonderful project. You are a god. How about focus confirmation? Digital range finder?
I'm just curious why you went with a Leica M Mount instead of a Leica C mount. Fantastic idea though. I am planning on building something similar and will definitely use some of your ideas.

What have you done. I never knew I needed a digital camera with a lubed zealio switch and artisan keycap - until now
I like your style MacGyver
So cool! interested to know is the grain seen in the results from post processing (ie photoshop or lightroom) or is it built into the image capture (handled on device)?
Photos were post processed with darkroom app but no grain was added, the grain is from the camera sensor itself
What lens is that? Jupiter-8?
May I advise moving the tripod mount to be inline with the center of the lens? This is how most cameras do it as it ensures that moving a tripod will move the image the same way no matter what direction you're moving it in.
Already done in the new version, hopefully a new video coming soon
Why not use the smallest possible lens mount you can find? Like MFT or even the lenses from a pentax auto 110.
What crop factor do you get with the focal reducer?
6:13 5x crop factor
@@LaurensiusAdiKun *with* the focal reducer
@@HansBaier At 7:58 it is said to be a 0.5x focal reducer, so a crop factor of about 2.5 then ☺ Brilliant project sir!
I was inspired by your focal reducer approach and made something similar for my camera! I converted a film camera to digital using a raspberry pi zero. ua-cam.com/video/Oc6Qiykgt5Y/v-deo.html
awesome work! How did you get all of the electronics packed in there?
Why didn't you make it with C mount , and just shoot with C mount cine lenses, to simplify your life.
I understand the concept of making a camera from the ground up, but this has really no use outside of a manmade box, the sensor is way too small, the the same result can be reproduce with a much cheaper older camera and there is no real use of the lenses with this build, also the magnifying glass seems to be pretty dodgy in general.
I am not against the idea, I just don't see this as a first step to something greater necessarily. Maybe if this whole thing was using a scanning sensor so at least we can have something that a phone camera nor the market cameras can reproduce, then that would be more interesting and probably a better use of this much creativity.
Even if not an amazing product it is still a product that can offer, I am not suggesting otherwise, I just feel it should take a different turn for it to have an actual use.
You're reinventing the wheel. Shoot film, it's got a 150 year long history of little improvements. No way you can beat that with your pathetic digits.
what is your problem sir? Let him cook
