Pros & Cons
👍 Pros
- Produces the classic deep infrared look with bright foliage and dark skies that lighter IR filters cannot achieve
- German-made B+W glass delivers consistent spectral transmission without hotspots or color casting artifacts
- 77mm thread size fits large lenses directly and adapts down to smaller lenses via step-up rings, making it a one-filter solution
- Sharp spectral cutoff around 650nm cleanly separates visible and infrared light for well-defined IR effects
👎 Cons
- The filter is essentially opaque — you must compose and focus before attaching it, which slows down your shooting workflow significantly
- Long exposures of 30 seconds or more are typical on unconverted cameras, limiting you to static subjects and requiring a sturdy tripod
- On cameras with a strong internal IR-cut filter, the effect may be too faint to be worthwhile without a full infrared conversion
- No indication on the filter ring of the exposure compensation needed, so you'll rely on trial and error or an external light meter for IR
Frequently Asked Questions
Will this filter work with my digital camera, or is it only for film?
It works with both, but results vary. Most digital sensors have an IR-blocking filter built in, which reduces the effect. Cameras that have been converted for infrared (with the internal IR-cut filter removed) will produce the strongest results. Unconverted cameras require very long exposures, often 30 seconds or more.
Can I see through the viewfinder with this filter attached?
No. The #092 filter is nearly opaque to visible light, so your optical viewfinder will go dark. You need to compose and focus before mounting the filter, or use live view on cameras that offer it. A tripod is essential.
What kind of look does the #092 produce compared to lighter IR filters?
The #092 (89B) is a deep infrared filter that blocks visible light up to roughly 650nm and transmits strongly above 730nm. This produces the classic infrared look — bright white foliage, dark skies, and an ethereal quality. Lighter IR filters like the #87 allow some visible light through, resulting in more subtle, reddish tones.
Do I need to compensate exposure when using this filter?
Yes, significantly. The filter factor is 20 to 40x depending on your light source and sensor sensitivity, which translates to roughly 4.5 to 5.5 stops of compensation. Shooting in manual mode or using exposure compensation is necessary.
What thread size is this, and can I use step-up rings?
This is a 77mm thread filter. You can absolutely use step-up rings to mount it on smaller diameter lenses, which makes 77mm a practical choice since it covers most lenses in a typical kit.
