Heliopan
Heliopan 48mm KB3 (82C) Cooling Color Conversion Glass Filter
Key Features
  • Rugged Brass Filter Ring
  • High Quality Schott Glass
With about twice the correcting effect of the KB1.5 (82A) filter, the Heliopan 48mm KB3 Cooling Color Conversion Glass Filter removes the orange-red color cast that appears on photographs made on tungsten reversal film with artificial lights using 100-200 Watt bulbs, or from aged photoflood lamps. Therefore, this filter is ideal for neutral color reproduction with appropriate illumination.

Heliopan Lichtfilter-Technik of Munich, Germany, has changed their black anodized brass filter rings on most Heliopan non-rotating filters to their "slim" mounts. These slim mounts are made of black anodized brass stock and have so little rim in front of the lens (5.4mm) that they will not vignette with lenses as short as 21mm.

Heliopan offers a wide selection of sizes, screw-in, series, bayonet, square and rectangular filters including digital, video, center weighted, graduated, wide angle, Kaesmann polarizers, drop-in polarizers, etc.

Note:
This filter is specific to lenses with Hasselblad's exclusive Series 60 (Bay 60) filter size
Maintains natural flesh tones; prevents reddish cast
Can create a mood of coolness
Heliopan cuts, grinds, polishes and coats their filters with the same techniques and equipment as used for the finest German camera lenses.
All Heliopan screw-in type and series size filters are mounted in precision black anodized brass rings to eliminate binding or cross threading and to ensure optimal alignment.
Filters still retain front threads for a lens cap, a lens hood or even stacking a second filter.
The portion of the Heliopan slim filters that are in front of the lens have been reduced in thickness by 37% over the former mount.
