To compensatefor this difference you have to align the chosen dis-tance against the red IR index and not the normalcentral index. Proceed as follows:1. Focus as usual.2. Note the distance on the focusing scale that is op-posite the central index line on the lens.3. Now rotate the focusing ring to set this distance op-posite the red IR index spot instead of the centralindex line.The illustration shows a lens focused at approx. 4metres for infrared film. See specific film instructionleaflet for details of filters, film storage, handling anddevelopment.Please make tests with your choice of infrared film beforeuse. High speed black and white infrared film, for example,can be slightly fogged on the edge of the film frame by thefilm transport emitter / sensor system.Flash ░38░There is flash sync at all speeds from B to 1/125 via thePC flash socket or hot shoe connector. Please see yourflash unit's user manual for further information.When the panorama format is selected, the flashshould be adjusted to cover the field of view. With the45mm lens you should choose an angle that wouldnormally be suitable for a 25 mm lens in the 35 mmformat. With the 90mm lens you should choose anangle that would normally be suitable for a 50 mm lensin the 35 mm format.The flash can be programmed to be triggered eitherat the beginning or at the end of the exposure. Pressthe MODE button on the camLCD for 1s. Pressrepeatedly until a flash symbol appears on the lower leftof the display accompanied by N (triggering at the begin-ning of the exposure) or R (triggering at the end of theexposure). Select your choice with the ▲ / ▼ buttons.Confirm by pushing MODE again or by pressing therelease button halfway. A flash symbol is shown on thedisplay as well as your choice (N or R).
