Diameter: M 55 (55x0,75)
Filter Type: Dark red / IR 600nm
Light infrared filter to get started with infrared photography. Ideal for the ADOX HR-50 or Ilford SFX film. The filter has only a double filterfactor, which means the exposure time must be doubled-or the aperture can be opened by one level.
Thus the ADOX HR-50 with 25 ASA can still be photographed from the hand.
Stronger infrared filters as we offer for example from Heliopan have filter factors of 4, 8, or 16 and can be placed almost without exception only with a tripod one. For this, they deliver more infrared effect.
Those who have met the fascinating infrared photography with the ADOX filter can then upgrade later.
