62mm C12 Blue Cooling Filter

The 62mm C12 Blue Cooling Color Conversion Filter is built for film photographers who shoot daylight-balanced stock under warm tungsten lighting. It matches 3200 Degree K ambient sources to 5500 Degree K film by reducing color temperature by 2200 Degree K with a -120 mired shift. The multi-coated glass cuts reflections and flare while maintaining over 97% average light transmission.

Capacity and Headroom

This filter handles the full conversion from tungsten to daylight balance in a single step, adding a deep blue hue that corrects warm light sources like low-power bulbs, candles, or halogen lamps. It also serves creative day-for-night effects on overcast days, delivering a convincing dark blue night feel. The 6-layer HMC coating ensures optical clarity reaches its limit only when light transmission drops below the 97% threshold.

Upgrade Path

The C12 replaces the need for an 80A equivalent filter, providing the same cooling conversion with modern multi-coating performance. Photographers using uncoated or single-coated conversion filters will see reduced ghosting and higher transmission. The jump is worth it when shooting critical color work on daylight film under artificial warm light where flare control and color fidelity are essential.

Questions about this item

Will the 62mm threads fit my older lenses that take 62mm filters?

Yes, the filter uses a standard 62mm thread size that matches any lens with a 62mm front thread.

How can I confirm the multi-coating is cutting reflections as intended?

Check for minimal flare and ghosting in high-contrast scenes; the six-layer HMC coating delivers over 97% average light transmission.

Does the package include a protective case or do I need to buy one separately?

The filter ships in its original box; a separate protective pouch or hard case is not included and must be purchased separately.
