B+W Polarizer 62 mm HTC Master MRC Nano. For this high-end polarizing filter the foil pieces are selected individually for maximum color neutrality. Following cementing between high-grade optical glass, additional grinding and polishing takes place. This guarantees outstanding sharpness even with very bright, apochromatic lenses.
Radiant white clouds against a deep blue sky or the deep colors of fall foliage don't happen by chance. B+W polarizing filters (polarizers for short) augment the purity of the intrinsic colors and increase color saturation and are among the most important filters for analog and digital photography. B+W Master polarizers is grease-free for easy rotation and the brass mount has optimized knurl for a better grip.
B+W Polarizer
The action of the polarisation effect always stems from the polarising film which is cemented (bonded) between two cover glasses. B+W polarising filters are then fine-ground and polished, which gives them their excellent optical quality. A high-quality B+W coating rounds off the quality of a B+W polarising disc.
HTC Polarizer
The Master High Transmission (HTC) polarizing filters is fitted whit a polarizing foil which has higher translucency (transmission), yet still provides outstanding effectiveness. The filter extension factor is only 2 to 3, equivalent to approx. 1 to 1.5 f-stops.
MRC Nano Coating
An important criteria for a perfect B+W filter is a high-quality coating, also known as an antireflection coating. With a B+W filter, such layers are evaporated by means of thin-layer technique, a quite complex coating process. The coating material consists of special substrates that are applied in one or more layers depending on the coating system.. In the MRC nano coated B+W filter, a water droplet remains practically spherical. It rolls over the surface. A first-rate dirt and water-repellent effect occurs.
Master Filter Holder
Durable and robust due to brass mount with better grip due to optimized knurl. Easier mounting due to new lacquer technology. Best choice for super wide angle – telephoto lenses.
