Pix of your home-built cams, mods and creations here please (part 2)


Oh I like the one of the cathedral doors and the woods (one of the 6x14's) I didn't see any Canon links.

Why 6x14 and not 6x12 like most manufacturers?

Thanks.

The "Canon" is the "Kiev EF" (http://www.meinezersaegtenkameras.de/Ekiev ef.html), a Kiev with a Canon EF mount.

As for 6x12 or 6x14, the plan was to use up the image circle of the Super Angulon as much as possible, which led to the 6x14 format. In hindsight this maybe wasn't a good decision, a) because of the vignetting and b) because the format sits somewhat between "just wide" and real panoramas, neither fish nor fowl.

Oh! That looks sweet!! Make me one please!

And isn't 6x12 the standard medium format panorama anyway? Just as 24mm x 64mm is the standard 135 format pano? Or is the medium formst 6x17 for visual reasons? I forget now... Haha all I know is scanners that scan pano film strips only accommodate for 6x12.

My Mamiya 7 has a "true panoramic" 35mm insert that creates the 64mm wide x 24mm high image on 35mm film, that's why I assumed 6x12 was pano since its the same proportions. Or is it? I'm tired and my brain doesn't want to do the math ratio (even if I know it's simple) Gnight for now, feel free to respond with mockery... Lol

No. 6x12 is twice as wide as it is high or a ratio of 2:1

64x24 is just over 2.5:1

Yes, I somehow am losing it, I think my instruction booklet for my mamiya 7 35mm pano insert was for the mamiya 6 and I'm just recalling the 2:1 ratio mentioned in the booklet for the 6 even though I have a 7, I think that's where my confusion lies.

In other news, here's a mod for a 70mm daylight tank for 15 feet of film at a time...



Yup, that's a single roll of film hanging in the shower...

The tank has a bit of light leak, if anyone has a REAL daylight tank I'll buy! Lol

Even in practice nothing is standard anyway, my 6x12 Holga is 50mm x 120mm, the DaYi roll back is 56mm x 115mm.....

 
Same 6x17 as before. But now with modified finder mask and a level. Also done up cosmetically. And this time I put a little effort in taking a good picture of it.

Nice.

What are you using for lens board clips?

Here are my two modified Nikon Fs. The left hand one has had the mirror box removed and has a leica thread mount. It is used with an external viewfinder with my 15mm Heliar. It is entirely successful and is quieter than my Bessa L. The right hand one is being converted to coupled rangefinder. The rangefinder that I am using is from a Konica Auto S3. I hope to finish it soon.

Well all the Cosina made rangefinder cameras Bessa, Zeiss Ikon, Epson etc are based on an SLR with the mirror box removed, and the Zenit C is a Leica copy rangefinder body witha mirror box so it's not an unknown concept After all the Nikon F isn't that different to the Nikon SP.

So interesting projects good luck.

Thanks Ian, when I was first thinking about doing it I asked for suggestions on a couple of other forums and the consensus was that I was daft to try.
I have also modified Nikon Photomic prisms by removing all the electrics, cutting down the chassis and making a new top to produce my own version of a standard prism for a cost of £20 instead of £120 that they sell for. As you can see they are not as pretty as the Nikon original but they do the job.

Bob, most DIY roll film cameras use the film counter numbers imprinted on the backing paper, and a hole with a sliding cover to see the number as it come around. The position of the hole depends on weather your shoot 6x45, 6x6 or 6x9. If you want to shoot 6x7 your out of luck..
 

So how would the advance distance be figured for example the 6x17 below? Guess I could ask the builder, eh?
 
On my 6x14 I use the Graflex film back counter plus an individual add on turning angle of the knob, which I have established beforehand (and put on a small table on the camera). So frame 2 is at counter position 2 plus 1 and 1/4 turns of the knob, frame 3 is at counter position 4 plus half a turn, and so on. To make this more accurate, I have "engraved" a kind of a windscale on the knob.

Regards,

Sven
 
Nothing much to show here other than me managing to get my CNC router to cut brass today!

Yeah, this would be exciting to me. The metal pieces that hold the lens board onto my Speed Graphic have gone walkabout. In addition, the bottom piece for the same on my Burke & James. I'm taping boards to my cameras. Heh.
 
DIY 8 X 10 camera complete

Finished my first home built camera this morning, using two store bought pieces from Skink (the pinhole and the tripod socket). Now if I can just complete the next two weeks of school and spend a little time with the camera. Plan a project next semester with this camera and making contact Ziatype prints and perhaps some others. It was a fun project with some help from folks here at APUG. John Goodman supplied the light seal material. Bill Barber
