The **Desmond Photographic 445009535567 IR 82mm 720nm 720HB Optical Glass Filter** is a meticulously crafted infrared (IR) conversion filter designed for photographers seeking to unlock the hidden spectral world beyond visible light. Engineered with **720nm optical glass**, this filter selectively transmits infrared wavelengths while blocking the majority of the visible spectrum, allowing photographers to capture ethereal, high-contrast images with an almost otherworldly quality. The **720HB (Hot Band) designation** indicates its optimized transmission peak at 720 nanometers, striking a balance between infrared sensitivity and residual visible light leakage, which can be further refined with post-processing or additional filters. Constructed from **high-quality optical glass**, this filter ensures exceptional clarity, minimal chromatic aberration, and durability, making it ideal for both landscape and architectural photography where infrared s unique properties such as the dramatic greening of foliage and the stark contrast of textures can be fully exploited. The **82mm diameter** accommodates a wide range of DSLR and mirrorless cameras, from full-frame to APS-C sensors, while its **threaded design** ensures a secure, vibration-free attachment to lenses, preserving image sharpness. Whether used alone for subtle infrared effects or stacked with other filters for deeper IR conversion, this filter is a versatile tool for artists exploring the boundaries of photographic expression. Its precision-engineered construction and reliable performance make it a staple for both emerging and seasoned photographers looking to push the limits of traditional imaging.
### Pros and Cons of buying a **Desmond Photographic 445009535567 IR 82mm Filter (720nm, 720HB Optical Glass)**
#### **Pros:**1. **High-Quality Optical Glass (720HB)** The filter is made from high-grade optical glass, which ensures minimal distortion and high clarity. The 720HB designation indicates excellent optical performance, reducing chromatic aberrations and maintaining sharpness.
2. **Precise Wavelength (720nm)** This filter is designed to block visible light while allowing near-infrared (NIR) wavelengths around 720nm to pass through. This makes it ideal for infrared photography, where natural or modified landscapes can be captured with a distinct, ethereal look.
3. **Durable Construction** The filter appears to be well-built, likely with a metal or reinforced frame to prevent bending or warping over time. This ensures longevity, especially if used with heavy lenses.
4. **Compatibility with DSLR and Mirrorless Cameras** The 82mm size is a standard screw-in filter size, making it versatile for a wide range of lenses. It should fit most DSLR and mirrorless cameras with 82mm filter holders.
5. **Good for Infrared Landscape Photography** If you're shooting infrared landscapes, this filter can produce striking, high-contrast images with a unique aesthetic. The 720nm range is particularly useful for capturing natural infrared reflections in foliage and water.
6. **Affordable Alternative to High-End Brands** Compared to premium infrared filters from brands like Hoya, B W, or Tiffen, this Desmond filter offers a cost-effective option without sacrificing significant quality.
7. **Easy to Use with IR-Enhanced Cameras** If your camera has an IR-modified sensor (e.g., modified Canon EOS or Nikon DSLRs), this filter will allow you to capture true infrared images without needing a full sensor modification.

#### **Cons:**1. **Potential for Lower-Quality Glass Than Premium Brands** While the 720HB designation suggests good optical quality, it may not match the precision of high-end filters from brands like Hoya or B W. Some users report slight color fringing or reduced sharpness compared to premium options.
2. **No UV/IR Cut-Off for Unmodified Cameras** If you're using a non-modified camera, this filter alone will not block enough visible light to produce true infrared images. You may need additional modifications (like an IR-modified sensor) or a combination of filters (e.g., a deep red filter this IR filter) to achieve proper results.
3. **Limited Brand Recognition** Desmond Photographic is not as well-known as established filter brands. While this doesn t necessarily mean poor quality, it may make finding replacement parts or customer support more difficult if issues arise.
4. **Possible Threading Issues** Some users report that cheaper filters may have slightly loose or inconsistent threading, which could lead to misalignment or difficulty attaching/detaching the filter. Always check the threads before purchasing.
5. **Not Ideal for All Infrared Applications** If you're working with very specific infrared wavelengths (e.g., 850nm or 940nm), this 720nm filter may not be suitable. It s best for near-infrared landscape photography rather than scientific or specialized IR work.
6. **Requires Proper Testing** Infrared photography can be tricky, and results vary depending on camera sensitivity, lighting conditions, and post-processing. You may need to experiment to achieve the desired effect.

### **Conclusion:**The **Desmond Photographic 720nm IR 82mm filter** is a solid, budget-friendly option for infrared landscape photography, especially if you're working with an IR-modified camera or need a cost-effective alternative to premium brands. Its high-grade 720HB optical glass ensures decent clarity and sharpness, while the 720nm wavelength is well-suited for capturing natural infrared reflections in foliage and water.
However, if you're using an unmodified camera, you may need additional filters or modifications to achieve true infrared results. The filter s quality is good but may not match the precision of high-end brands like Hoya or B W. If you're serious about infrared photography and plan to invest long-term, testing a few different filters (including premium ones) could be worthwhile.
### **Recommendation:**- **Buy it if:** You're on a budget, shooting infrared landscapes with an IR-modified camera, and want a decent-quality filter without breaking the bank.
- **Consider alternatives if:** You need the absolute best optical quality, plan to use unmodified cameras, or require filters for very specific infrared applications.
- **Test it thoroughly:** Since infrared photography can be unpredictable, take multiple test shots under different lighting conditions to evaluate performance before committing to it for serious projects.
For best results, pair this filter with proper infrared photography techniques, including using a deep red filter (like a 720nm or 742nm) for unmodified cameras or ensuring your camera s sensor is IR-sensitive.
