The 62mm Hoya C2 Blue Cooling Filter 62mmcools the ambient light entering the lens by 200° Kelvin, a -20 mired shift by adding blue to the overall exposure. This filter helps fine-tune the color or look of your scene to match your film's white balance.

Designed for Film Photographers    Adds Blue Cooling Effect    Reduces Color Temperature by 200°    6 Layers of HMC Multi-Coating    Equivalent to 82A Filter

The Hoya C2 filter is helpful when:

• You are using tungsten-balanced film, the light source is warmer than the traditional 3200K, and you need a specific amount of color correction to match your film type. Candles and low-watt incandescent bulbs are examples of warm light sources.
• You are shooting at sunrise or sunset with daylight-balanced film (5500K), and the overall scene is too warm. The filter will help cool the scene for a more natural look.
• Hoya Multicoat (HMC) filters are recommended for enhancing the performance of today's multicoated lenses. These popular filters minimize reflection, reduce flare and ghosting, and result in over 97% average light transmission.

A: Yes, any circular polarizer will add stops to the exposure, it depends on the polarizer as to how many stops are added.

Q: 2. i'm new to photography. can i stack this filter with a protective clear filter or uv filter? i use a nikon d5300 and a af-p dx nikkor 70-300 ed vr telephoto

Q: 6. Is this the same filter as the Hoya NXT Circular Polarizer filter, just updated?

A: According to Hoya, the NXTPlus filters are improved over the NXT-series because they "use better glass, an improved multi-coating process, more multi-coated layers for better light transmission, AND add a new 'Waterproof' Top-coat to repel water quickly away from the surface which makes it easier to clean and more fun to use."
