- Manufactured by Hoya with consistent optical quality across the filter surface
- Manufactured by Hoya, a well-established name in professional optical filters
- Simple, reliable optical solution that requires no batteries or digital processing
- Simple screw-on 62mm design requires no adapters for matching lenses
- Provides an optical warming effect that can reduce post-processing adjustments
- 62mm thread size fits a wide range of mid-sized lenses
- Useful for both film photographers needing color correction and digital shooters wanting in-camera warmth
👎 Cons
- Largely redundant for digital photographers who can adjust white balance in camera or post-processing
- Primarily designed for film photography, limiting its necessity for most digital camera users
- Minimal product description suggests a basic filter without advanced coatings for flare or scratch resistance
- Limited to a single color conversion function with no adjustability
- Minimal product information provided regarding coating type or glass quality
- Single-purpose filter with a narrow use case compared to more versatile options like polarizers or NDs
- No information provided about multi-coating, which may mean lower flare resistance than coated alternatives
- Adds an extra element in front of the lens, which can introduce slight softness or reflections
- Only available in 62mm, requiring step-up or step-down rings for other lens sizes
Frequently Asked Questions
What does the Hoya 85B filter do?
The 85B is a color conversion filter that shifts color temperature, specifically designed to correct the blue cast that occurs when shooting daylight-balanced film under tungsten (incandescent) lighting, bringing colors back to a natural, warm appearance.
What does the Hoya 85B color conversion filter do?
The 85B filter converts the color temperature of daylight (approximately 5500K) to match tungsten-balanced film (approximately 3400K), allowing you to shoot daylight-balanced scenes on tungsten film without an orange color cast.
Is this filter useful for digital photography?
While digital cameras can adjust white balance electronically, the 85B can still be used to apply a warm color shift in-camera, reducing post-processing work for photographers who prefer optical correction or want a consistent warm tone across a shoot.
Is this filter useful with digital cameras?
Digital cameras can achieve the same color temperature adjustment through white balance settings, making the 85B primarily useful for film photographers. However, some digital shooters use it for creative warming effects or to reduce post-processing work.
How much light does the 85B filter absorb?
The 85B typically requires an exposure compensation of approximately 2/3 of a stop, which is a modest amount of light loss for a color conversion filter.
What size lenses does this filter fit?
This is a 62mm filter that threads onto any lens with a 62mm front filter thread.
Can the 85B be stacked with other filters?
Yes, it can be threaded onto other filters, though stacking multiple filters increases the risk of vignetting, especially on wide-angle lenses.
Can I use this filter for video?
Yes, the 85B is commonly used in film and video production to correct color temperature when shooting with daylight-balanced film stock under tungsten lights, or for warming effects with digital video.
What is the difference between the 85A and 85B filters?
The 85B provides a slightly stronger warming correction than the 85A. The 85B converts from approximately 3200K to 5500K, while the 85A converts from 3400K to 5500K, making the 85B better suited for standard tungsten lighting.
How does the 85B differ from an 85 or 85C filter?
The 85B provides a moderate warming correction, sitting between the stronger 85 and the lighter 85C. It is specifically calibrated for converting 5500K daylight to approximately 3400K tungsten balance.
