TEKTRONIX C-30A CAMERA Tektronix manufactures test, measurement and monitoring equipment and have 675 patents according to their web-site, but possibly the coolest thing they have ever made, in my opinion, could just be the C-30A Oscilloscope camera with Polaroidback. This camera, sadly no longer manufactured, can be found where second-hand technical equipment is sold for those wanting to push the boundaries of close-up Polaroid photography. The C-30 camera was originally designed to capture osilloscope waveforms by being attached to the front of an oscilloscope's CRT display but is conveniently applicable to close-up photography work. With magnifications from 0.7 - 1.5 X this camera can capture tasty close-ups and macros to 100/600 type Polaroid peel-apart instant film to give instant macro happiness! It's also great for weight-training - at 25(H) x 19(D) x 13(W)cm dimensions this metal and glass beasty is not to be sneezed at! (unless you are allergic to macro photography I suppose) Specifications: Lens: f/1.9 Magnification: 1.5 to 0.7 in ten detent steps - 0.8 with corrector lens Standard Shutter: Mechanically actuated, 1 to 1/60 sec, plus Bulb and Time Field of view: 10 x 8 cm at 0.8X Film Backs: Polaroid Pack Back (review by artpunk)
