Shopping list:

A Polaroid Land Camera Swinger Model 20

A good brand epoxy glue

A set of Canon EF Macro Extension Rings. I just got some cheap ones. Mine has 7,14 and 28mm. written on them. Others has numbers 1,2,3 on them. Get the 7,14 and 28mm. ones if you can. I don't know if the others are the same size. You should get this with the AF-Confirm chip installed.

Some Canon EF Macro Bellows. Again I got the the cheap stuff. You should get this with the AF-Confirm chip installed.

A Phillips head Screwdriver

A Compass. This is for drawing circles, not for finding the North Pole

A Ruler and a Vernier Caliper.

A flat black piece of plastic sheet 5x5 cm. You can get this from smashing the remains of the camera body.

A flat black permanent marker. I used a Posca marker.

Some paper.

Scissors

Note: AF-Confirm is when your normal AF lenses, confirms that you have reached focus. This is pretty handy, so get your adaptors with it.

it looks the business and it works as well! would like to see a straight on shot of the final camera assembly. how did you find using it with the crop factor.

Ok I'll snap that shot for you. There's no vignetting on my 600D. It does get a bit dark in the viewfinder with the higher apertures. But overall I like it.

Picture added. It has a vintage Minolta Polarizing Filter on.

just noticed that this is your first instructable, its a good one, lots of info, people like that. thanks for snapping the pic, didnt fully realise theres extra filter bits on the front,i saw the pic with the bellows and sort of presumed,ha ha , i confess i am a bit of a skimmer when it comes to reading pretty much anything.
any way congratulations on this success and hope to see more like it.
personally i would have chosen a smaller polariser in order to not hide the polaroid boxy look ,it may help reduce flare in the optical chain, but hey thats just personal choice i have nothing against circles .
G. M. (author)  crazyg1 year ago
Thanks. Yeah I was looking for a 37mm filter, but I only had 30, 52 and 58. 30 is to small, so it was a quick decision. As you can see in the 3'rd picture I have an extra one in the back. When I get some 37mm filters I will change it.

Great stuff. I really like your "digital contact print film camera" it is a very interesting concept.
Also how do you get picture on the intire 35mm film? Like over the sprocket holes?
crazyg G. M.1 year ago
if its one iv made i just give it a big hole,
the lomo cameras , spinner, diana with 35mm adapter, and holgas with 35mm adapters.can shoot over sprocket holes styraght out the box.
making a diy adapter isnt so hard ither,
id recomend the holga colour flash,
most plasticy point and shooters have redundant plastic around the film which can be chopped off.
i scan my own negs cos custom printing is a hassle.
the contact camera , i really wanted to get pixels onto film, think il have to use a slide enlarger for this which wont look nice, i will think of something.
G. M. (author)  crazyg1 year ago
Thanks for the advice. It sounds very interesting. How about doing a colaboration? If have some ideas about getting pixels on there aswell. How many pixels do you want?
crazyg G. M.1 year ago
sounds interesting,allways interested in throwing ideas around., im up for some build off challenges.
pixels however many is on a low grade lcd,
(they keep making the dam things better) keeping the screen to film scale 1 to 1 . when enlarged you can see the rgb.
im currenty working on a mostly scrap brass medium format camera. kinda copying this, (i found this image when researching the spinner360 camera, i was sure it was a copy of something)
today i got the basics of the shutter together it can be slit format or a twin guillotine sort of thing, not many shutters with lead and brass curtains.
and it will accept m42 lenses. looking forward to exploring the far edges of the image circle especially of my fisheye lens.

Holy ---- those look awesome. How about a gameboy camera? That will get you pixels. What size is that lcd?
crazyg G. M.1 year ago
Want a bit more definition than 8 bit at the beginning so there's space for some degridation, below is a GBC image that I finally freed from the camera,had to get an enormous win98 machine just for that purpose. Think the screen from a old digital can (6years) as long as the screen is about 35mm high, like the idea of having the battery condition and mode graphics on the final image,
Then it can go three o ways using a SLR with slide adapter allows use of the digital end but cuts the sprocket holes. Or making the cam support 2 screens sorting out a focus lens and shutter or cutting the backlight power .
Then again there's the past I route converting a point and shoot to macro ,hacking the insides a bit .then being clever with glass and mirror to get a preview.being skint helps the creativity

You can make the Mad Catz gameboy cable work with WIndows XP. It's tricky but it works.

One could simply put the screen and camera infront of a macro lense, and you can use the viewfinder. But then the exposure will not cover the sprocket holes, only the normal 35mm.

Oh i just found he perfect camera to mod in my bin. It's a Zeiss Ikon Contessa with a broken aperture.

Hello G.M. Your instructable is really interesting and I will try to make one of those lensses for my D5 Mk II, but is that flash on step 4 an old Sunpak for film cameras atached to the hot shoe of a digital camera? it is supposed to burn the camera electronics due to the high voltage used on those old flash guns, or is that a false statement?
crazyg joeruiz1 year ago
look up optocouplers , i found that a tlp3042 works good. its a nibbin that connects the signal but isolates the voltage:-)
G. M. (author)  joeruiz1 year ago
It is a National, but yes it is for analog cameras. I only used it for show.
