Best Infrared Lens Filters

Comprehensive Guide to Finding the Best Infrared Lens Filters

Infrared (IR) photography has always fascinated photographers due to its ability to capture unique and ethereal images that are not visible to the naked eye. Whether you're a professional photographer or an enthusiast, finding the best infrared lens filter is crucial for achieving stunning results. This guide will walk you through the essential aspects you need to consider.

Understanding Infrared Photography

Infrared photography involves capturing light in the infrared spectrum, which is beyond the visible range of human eyes. Standard cameras are designed to block infrared light, so using specialized filters is necessary to allow infrared wavelengths to reach the camera sensor. These filters block visible light and let only infrared light pass through, creating surreal and dreamlike photographs.

Types of Infrared Filters

Infrared filters come in various types, primarily differentiated by their wavelength cut-off points, measured in nanometers (nm). The most common types are:

1. 680nm Filters: These allow some visible light to pass through, resulting in images with more color.
2. 720nm Filters: The most popular choice, these filters block most visible light, providing a balance between color and infrared effects.
3. 850nm Filters: These block almost all visible light, producing high-contrast black-and-white images.

Choosing the right filter depends on the effect you want to achieve. Beginners often start with a 720nm filter due to its balanced characteristics.

Material and Build Quality

The material and build quality of an infrared filter are crucial for both image quality and durability. High-quality filters are typically made from optical glass, which ensures clarity and minimal distortion. Cheaper filters might be made from resin or other plastics, which can degrade image quality and are more prone to scratches.

Coating and Anti-Reflective Properties

Coatings play a significant role in the performance of infrared filters. Multi-coated filters reduce reflections and glare, which are particularly important in infrared photography due to the nature of the light being captured. Anti-reflective coatings also help in maintaining the sharpness and contrast of your images.

Compatibility with Lenses

Ensure that the infrared filter you choose is compatible with your lens. Filters come in different thread sizes, so you need to match the filter size with your lens diameter. Some photographers invest in a set of step-up or step-down rings, which allow them to use a single filter on lenses with different thread sizes.

Brand Reputation

The market is flooded with various brands offering infrared filters, but not all are created equal. Reputable brands like Hoya, B+W, and Kolari Vision have established their credibility by consistently delivering high-quality products. Reading reviews and seeking recommendations from experienced infrared photographers can provide insights into the most reliable options.

Ease of Use

Infrared photography can be challenging, especially for beginners. Some filters are easier to use than others, depending on their design and the ease with which they can be mounted and removed from the lens. Filters with a slim profile are particularly useful to avoid vignetting, especially on wide-angle lenses.

Price Considerations

While it might be tempting to go for cheaper options, investing in a high-quality infrared filter can make a significant difference in the quality of your photographs. Higher-end filters offer better materials, coatings, and overall performance. However, there are also mid-range options that provide good value for money without compromising too much on quality.

Experimentation and Practice

Finally, remember that infrared photography has a learning curve. It requires experimentation with different filters, camera settings, and post-processing techniques. Patience and practice are key to mastering the art and finding the perfect filter for your needs.

Conclusion

Choosing the best infrared lens filter involves a careful consideration of various factors, including the type of filter, material and build quality, coatings, compatibility, brand reputation, ease of use, and price. By understanding these aspects and experimenting with different options, you can find the ideal filter to capture stunning infrared photographs that stand out from the ordinary.
