I wanted to have a wide-angle instant camera and this seemed like one way to go about that.\u00a0A few years back I received this lens and shutter and had paid very little for the Polaroid camera.\u00a0 The first thing I did was to remove the lens, shutter and all the electronics from the existing camera and make small modifications to fit the new one (There are still some cosmetic changes to be made).\u00a0 The lens has 6 elements and is designed to cover an image of 65mm x 95mm with some shifting.\u00a0 Fortunately Fuji FP100c’s\u00a0image area is 73mm x 95mm. It does however result in vignetting\u00a0when used wide open.\u00a0 The lens has a field of view of 80 degrees which equates to about 25mm on 35mm film that is pretty wide for a Polaroid.<\/p>\n

The registration distance is different for the new\u00a0 lens so I needed to figure out a different method of focusing.\u00a0 I found that as part of the collapsing mechanism I was able to add what amounts to a measuring stick with marks for important distances.\u00a0 This ‘Stick’ slides in and out as the lens is moved back and forth.\u00a0 In order to calibrate this I cut drafting\u00a0applique and put it in an old film holder so that it was at the same location in the camera as the film would be. I then measured the distance for different points\u00a0where that image was in\u00a0focus and marked them on the ‘stick’.<\/p>\n

The new focusing allows for close focusing all the way to 5″ however\u00a0going the other way once\u00a0you focus past\u00a03 feet\u00a0it becomes difficult to make changes as the differences become very slight.\u00a0However with such a wide lens it’s not really a problem with whats in focus extending from very near to\u00a0infinity focus.<\/p>\n

The lack of a tripod mount is probably the largest problem I have and will look to address as I make improvements.\u00a0 Having to hold the camera while also focusing by pulling the lens in and out and tripping the shutter is a little too cumbersome.\u00a0 Here are the first four sample images from my new Frankenroid.<\/p>\n\n\t\t
