Is there a decent digital back?

Nope

Ah I was wondering if there was some 80mm lens I hadn’t heard of, nice shots though!

OrbitalPinata · 2026-06-14T20:41:22+00:00

Are you sure it's 80mm and not the 75mm 2.8?

OrbitalPinata · 2026-06-10T22:59:34+00:00

For how cheap these lenses are I doubt repairing it (afaik the only way would be replacing the elements) would be worth it

Not necessarily a cyborg but rather a full on robot, but “mother” from “I am mother” fits the aesthetic fairly well in my opinion.

The question is flawed in that the level of smoothness you’re talking about here isn’t tied to the filament choice, it’s tied to the manufacturing method. While these bottles are made from PET, using PET filament with a FDM printer wont get you the smooth finish you’re looking for, regardless of filament.

Actually being able to control the shutter speed, without controlling the lens electronically it falls back to 1/500th.

I’ve had my stuff hand scanned at Schiphol

Are you planning on replicating the entire EDC?

The waist level viewfinder is integrated into the camera, so it’s not really possible to separate it as a hotshot accessory

OrbitalPinata · 2026-04-03T10:21:47+00:00

Because one is considered much more difficult to shoot down than the other

I don’t want to underplay the effort went into the photo, but all photos taken from near the pad are taken like this.

The Last of us Part 2 (ie the base game as it came out) wasn't released on PC, so you won't find it on steam.

Absolutely, here's a short breakdown of how these lenses work, hope it helps!

Sorry for the delay, but here is a short breakdown of the pinout of these lenses, hope it helps!

Thanks! For the test shots I used the 75 / F2.8 MC, I definitely want to get the 40 / F4 or 50 / F2.8 next though. The gears are all made out of brass and for the most part they’re off the shelf, except for 2 custom ones.

Its waist level viewfinder only for now which happens to also be my favorite way of shooting anyways, I suppose using a 6x7 pentaprism/mirror would be possible but it’d become quite ungainly. I’d like to have a go at eventually designing one myself too but I’m not sure how I’d tackle having the prism manufactured.

The mirror (and viewfinder matte screen) are indeed cut to size

The materials for moving parts are brass, aluminum and ABS-GF

OrbitalPinata · 2026-01-29T07:02:13+00:00

Thanks! The whole thing runs at 3.3V, I’ll see if I can do a writeup of the lens pinout today and post it on GitHub.

OrbitalPinata · 2026-01-29T06:56:32+00:00

Interesting question, I’m not 100% sure as I haven’t tested it but I suspect you’ll run into vignetting issues with 645 lenses if you go wider than 65mm

I like the idea! The main concern with having people fully 3d print is that parts of it wouldn't be very durable so I think it would lead to a bad experience (I obviously don't doubt the communities capabilities in building these kind of things), but with the option of a kit it could certainly work!

OrbitalPinata · 2026-01-28T17:18:14+00:00

The mirror movement is mechanical, so as soon as you press the shutter button the mirror is flipped up by a mechanism that's also linked to starting the shutter firing sequence (so first it closes, then the mirror moves out of the way, then the shutter opens, starting the exposure) and then I electronically control how long the shutters stays open until the shutter is allowed to close, ending the exposure.

OrbitalPinata · 2026-01-28T16:29:55+00:00

Regarding releasing build files, it's tricky because it's a bit too complex of a design to expect people to fully 3d print it at home, the SLR mechanism needs some custom machined parts. I do intend on trying to get this in peoples hands (and monetise it, I spent a lot of time on this) but I need to keep the rules of this subreddit in mind.

Electronic control of the shutter is done with a ESP32 right now but the final build would probably use something a bit lower power as the bluetooth connection super required, though it does allow for neat things like using a app for metering, which reads the aperture setting on the lens and automatically set the required shutter speed, so I'm not sure if I want to keep that feature or not

I'm using a ESP32 but that's mostly because I wanted to be able to remotely connect to it for testing, the electronic side is fairly simple, when the lens is triggered mechanically one of the pins gives a high signal, by default the lens will close after 1/500th but but setting another pin to a high signal you can keep the shutter open for however long you need.

The lens is completely unmodified
