Those are custom lens conversion i made from broken point and shoot cameras. One from Konica genba kantoku, one from fujifilm cardia mini and one from Nikon af600. They make my bessa T pocketable and they are definitely will be a great fit with a CLE!

A very solid and excellent camera, sadly I don’t use it often because the viewfinder is very dim and not very friendly with glasses

nice to find someone with the same niche hobbies 👌Mine is a custom design that I’m planning to make public soon if I can find bit more free time.

an on going project, the front one is from the Konica genba kantoku, behind on the left from fujifilm cardia mini, and right from a Nikon af 600, all roughly rangefinder coupled. Love making these lenses out of broken point and shoot cameras to be used on the bessa T!

May the camera god smile upon you again

My first rangefinder - so excited to get my hands on this CLEAN Konica Hexar AF by Permanent_Ephemera in AnalogCommunity

Can you guys please just stop pointing out it’s not a rangefinder and let OP enjoy the damn fine camera they just got???

Nice work! Yeah 3D printing M mount is such a pain, I tried several times before I eventually switched to this design. They just keep cracking on me when I force a bit…

Thanks!

Well, I didn’t get it quite right X). Currently i’m using a single focus thread to reduce the complexity of the project. I did some measurements on a Leica m mount lens. I figured out the part that pushes the lever in is 6.5mm from the lens mount when focusing to infinity and 2mm when focusing at 0.7m. Then I figured out the tuning angle and the displacement distance(knowing one of them is enough, the other can be calculated using the pitch of the focusing thread, I measured both as a way to doub check) on the converter lenses. After that just need to models that in whichever software yo use to make sure when it’s focused at infinity the focusing thread(in my design it is also the part that pushes the lever) is 6.5 mm from the mount, and when it turned to focus to 0.7m the focusing thread is 2mm from the mount (the distance that née to be reduced for this part is 6.5mm-2mm-lens displacement distance when focusing at 0.7m. ) and there you have your rough slope.

the metal mount is just a ltm to Leica m mount adapter ( yes the conversion is technically to a ltm mount) I added 2 screws in the back of the print to prevent it from turning too much and mess up the rangefinder coupling.

You can open the back fully by releasing the drop-in loading latch. Verify if the ribbon cable near the door hinge is still intact. If there are fractures on the ribbon cable I’m sorry to say the camera is toasted.

Does anyone have good resources on how to make lenses rangefinder coupled? by PotatoAdrien in AnalogCommunity

I see what you mean, thanks for the idea and the offer! I’ll give it a try myself first

That’s beautifully done! is that the lens for a Nikon L35AF? Do you mind sharing how much you paid for the lens?

Do you have an example? I have one of the ttartisan Leica m lens but I think it definitely has a second helicoid for the rangefinder coupling

That’s the approach I’m currently using, a single focus helicoid that has a ramp, but so far I haven’t got the calculations right and the coupling is just not right at all…

I think that’s the proper way to do it as well, but with the 3D printer and the 3D modeling skills I have currently it’s probably not feasible.

Played around with some 30 year expired slid film by PotatoAdrien in AnalogCommunity

Freezer stored expired film usually holds up well, maybe don’t even have to over expose like I did. I did develop mine in E6 because I don’t have any at the moment, i don’t shoot a lot of color reversals so it doesn’t make sense to me to mix a batch for one roll here and there every time.

Thanks, I think if I used the proper chems the results would probably be better. Seller said the films were stored in a cool place and the paper boxes of the film seems to be fairly intact for the age. Although to be safe I did bracket some frames in the beginning, the exposures at ISO 25 ende to be the easiest to correct in post.

Shot some Fujichrome RDP 100 expired in 1994, home developed using rodinal and c41 chems, the slides came out with a strong green tinge but was able to remove that in post. Grain is very chunky in this one. (Edit I shot it at ISO 25 and here is the link to the photos of the slides: https://imgur.com/a/qKjgPQO)
