patrick j dempsey Posted March 29, 2007 Share Posted March 29, 2007 Heres a camera thats almost completely useless. It is STRICTLY a portraitcamera which has a single element plastic lens with a fixed focus... and a fixedfocus rangefinder! Possibly one-of-a-kind in the photography world! I think Imgonna convert mine into something else.... so heres how to disassemble the frontof the camera. First thing to come off is the plastic Fresnel lens. Its pretty fragile and Ibroke mine. push up on the top part of the grey frame while pushing out on thefresnel lens from behind. It takes some force to get it out from the top. Nowyou will notice that it is still attached on either side of the lens by tabsgoing into the grey frame. I didnt realize untill I broke mine how to get itout... notice that looking into the lens, the slot on the left side is muchlonger than the slot on the right side. I beleive you can twist the fresnelplastic to the right and pop the whole peice out without breaking it. The peice of silvered paper saying "Big Shot" will now fall off. Now you seethe black aperature ring and lens. The black aperature ring is attached by tabson each side. Insert a small flat-blade screwdriver to release these tabs. Thewhole peice will then pop out easily. The Lens is now revealed. Thesingle-element lens is attached by 4 tabs... again the flat-blade screwdrivereasily opens the tabs and the lens comes out. Now for the screws!!! At the top right and bottom left are two phillipsscrews... set VERY deep into the face. It requires a small screwdriver with avery long shaft to get them. I do not beleive a standard screwdriver will fit inthe holes. These screws remove the dark grey peice in the front of the camerawhich contains the aperature assembly. Now the shutter assembly is revealed. One circlip on the orange-red shutterswitch hold the entire rest of the assembly in.... that and all the springs thatcome shooting out. ;) Oh well, that was fun... now for the hacksaw... I plan on putting a large-formatCompur Shutter and Kodak Lens into this puppy.... should be tons of fun. Link to comment Share on other sites More sharing options...
dave_powell2 Posted March 30, 2007 Share Posted March 30, 2007 Or... mount a suitably sized pin-hole. With a snood like that puppy has, it will become fairly telephoto! Dave Link to comment Share on other sites More sharing options...
patrick j dempsey Posted March 30, 2007 Author Share Posted March 30, 2007 Nope. Hacksaw. Theres a mask inside the Big Shot which makes a perfect place to begin mounting a new lens and shutter. With a great deal of adapting... including adding some carboard because I cut it too short... Ive added a Kodak large format setup. Compur shutter and Kodak Anastigmat 135. Ive mounted the rear element to focus for infinity at 110mm and moved the shutter and front element further forward to focus at about 4 feet. This allows the camera to use the rangefinder and provide close focus with limited depth of feild.... or infinity focus at the smallest aperature. At a total focal length of 150mm the aperature scale is now off by 1 stop, turning the f4.5 into an f5.6. Im also adding strap lugs and a tripod mount to make this a more user friendly camera! It wont have that "portrait" look of the 220mm Big Shot... but it will at least have nice optics and a real shutter. Link to comment Share on other sites More sharing options...
minhnguyen9113 Posted March 31, 2007 Share Posted March 31, 2007 Patrick, What kind of film you use for that camera ? Interesting idea, post some pictures so we can see and offer help if you neeed. Link to comment Share on other sites More sharing options...
patrick j dempsey Posted March 31, 2007 Author Share Posted March 31, 2007 Beleive it or not Mihn, but polaroid still manufactures and sells Pack Film! The Big Shot takes 3.25"x4.25" Pack Film. 10 Images per pack. In fact they just introduced a NEW Pack Film... 690 film.... available emulsions from Polaroid: 690: ISO 100 Color Film, Improved color saturation and grain 669: ISO 80 Color Film, daylight balanced, color shifts at different exposures 667: ISO 3000 B&W Film, used for industrial purposes... might be fun at night? (I have a 3000 speed filter for the older polaroids in my collection) 672: ISO 400 B&W Film, medium contrast and fine grain 664: ISO 100 B&W Film, wide tonal range, fine grain PC ID-UV: ISO 80 Color Film, used for security photos, hidden UV text saying "polaroid" 690 film takes the place of 679 and 689 films which have been discontinued. Ironically it seems that Polaroid offers more vareity of Pack Film than 600 films.... probably because it can be used in the Daylabs as well as a variety of PackFilm backs for professional cameras, as well as the 600 SE professional and a variety of security passport cameras, and slide copiers. Just because you cant buy the stuff at KMart doesnt mean it isnt one of their biggest sellers! It costs about the same as 600 film... a little over $1 an image. For me that is about the same I pay for medium format... and i dont even get prints... thats just buying the film, processing the negs and getting them scanned to disk... about $15 for 12 images.... Pack Film is about $25 for 20 images. Link to comment Share on other sites More sharing options...

minhnguyen9113 Posted March 31, 2007 Share Posted March 31, 2007 If you mount the good lens on a Polaroid 250 the result is better, you have a folding camera which has Zeiss ranger finder and focus-able it might be better than the pricey Polaroid 180 or 190 ones. Specially the 250 comes with an aluminum body. Minh Link to comment Share on other sites More sharing options...
patrick j dempsey Posted April 1, 2007 Author Share Posted April 1, 2007 I actualy just picked up a 104 yesterday for $2 at goodwill to attempt some different conversion to.. At this point I cant afford film so it will be awhile before I can do thorough tests.... but that you very much for the advice! I have read about the 250... legendary! The veiw-finder in the 104 has brightlines with arrows that move... looks like the in-flight nagivation projections for jet fighters... crazy stuff.

minhnguyen9113 Posted April 2, 2007 Share Posted April 2, 2007 Patrick, if you want to try your camera I'll send you some Polaroid film packs I have couple years ago, I do not use so they are laying in the refrigerator. I mounted a good lens on a 450 but don't use much because of no negatives, you can have the film for your tests. Hopefully the pictures will be good.

david_m Posted April 7, 2007 Share Posted April 7, 2007 There are pack film Polaroids that already come with a lens like that. The CU5. I believe it was used for dental photography. There is even a ringlite available. You could have saved yourself a lot of work. Link to comment Share on other sites More sharing options...
patrick j dempsey Posted April 11, 2007 Author Share Posted April 11, 2007 Well whats the fun in that? :P This camera was free and the lens and shutter I got for about $5 because it was "broken". (Just needed to be rebuilt) Im a born tinkerer... if someone told me I wasnt ALLOWED to tinker I think Id snuff it! One of my good friends just built himself a lensbaby out of an old bellows and an anceint Rolleiflex shutter and lens. Sure he could have just dropped $300 on a peice of vaccuum cleaner hose and a crappy lens that someone else put together, but besides the fact that he got the parts from cameras he makes money from repairing and selling on ebay, it was the tinkering that really inspired him. The fact that without much work or money he could build something that people are paying a VERY pretty penny for is part of the fun! Heck if the attitude is that its senseless to do something because its already been done then you might as well quit photography and kill yourself... because its ALL already been done! ;) Link to comment Share on other sites More sharing options...
hhargreaves Posted October 8, 2007 Share Posted October 8, 2007 I love the look this camera gives with the 690 polaroid, and remember the standard model of this camera is what andy warhol used for the majority of his portraits! Link to comment Share on other sites More sharing options...
