11. I35 Modell 300 The difference between the MINI35 Model 300 and the Model 400 is the movement of the target and the diameter of the optical channel The rotating ground glass of the Model 300 results in a dot in the middle of the image which is particularly visible in against the light shots Therefore the movement of the ground glass has been changed into an oscillating movement for the Model 400 The first camera models required a smaller diameter of the optical channel When using the Model 300 with some newer camera models problems like black frames can appear This is the reason why the MINI35 Model 400 has a larger optical channel All previous PRO35 Image Converters can be upgraded to MK Il for that purpose con tact P S Technik or your local distributor 2 3 3 Flange focal distance and Back focus There are two lens mounts on the MINI35 Image Converter on the lens side PL Mount Nikon and on the camera side Bayonet Mount Hence there are two possibilities to ad just the flange focal distance 1 The lens mount for the film and photo lenses on the front of the Image Converter has a factory preset flange focal distance identical to film cameras 2 The camera side Mount of the MINI35 can be adjusted with the back focus ring on the relay lens or with the focus ring on the camera s lens P S TECHNIK 2 Professional Cine Equipment Manufacture dy When is an adjustment
