The **Hoya Y1UVIR077 UV-IR Screw-In 77mm Lens Filter** is a meticulously engineered optical accessory designed specifically for Blackmagic Cinema Camera users seeking to enhance their cinematography with superior clarity, color accuracy, and reduced lens flare. Crafted from high-quality optical glass, this filter effectively blocks both ultraviolet (UV) and infrared (IR) light, ensuring that your footage captures only the true, unaltered spectrum of visible light. UV rays, which are abundant in outdoor and high-altitude environments, can cause lens flare, haze, and an unnatural blue cast in images, particularly when shooting through glass or in bright sunlight. By eliminating these unwanted wavelengths, the Y1UVIR077 restores natural colors and sharpness, allowing for more vibrant and professional-looking visuals. Similarly, infrared light, which lies just beyond the visible spectrum, can introduce unwanted reflections and color shifts, particularly in low-light conditions or when using wide-angle lenses. This filter meticulously absorbs these IR rays, preventing them from interfering with your camera s sensor and ensuring a cleaner, more accurate image.
Beyond its primary function of light filtration, the Hoya Y1UVIR077 is built to deliver exceptional optical performance with minimal distortion or vignetting, thanks to its precision-machined edges and multi-coated surfaces that enhance light transmission while maintaining image fidelity. The filter s screw-in design, compatible with 77mm lens mounts, ensures a secure and interference-free fit, making it ideal for both still photography and video applications. Whether you're shooting in challenging outdoor environments, capturing high-contrast scenes, or working with wide-angle lenses where flare is a common issue, this filter provides a reliable solution to achieve cleaner, more polished results. Additionally, its durable construction and scratch-resistant coating make it a long-lasting investment for professionals who demand the highest standards in their equipment. For Blackmagic Cinema Camera users, the Y1UVIR077 is an indispensable tool for achieving cinematic quality, reducing post-production cleanup, and ensuring that every frame reflects the true intent of the scene.
**Pros and Cons of buying a Hoya Y1UVIR077 UV-IR Screw-In 77mm Lens Filter for Blackmagic Cameras**
### **Pros**
1. **UV and IR Blocking** The filter effectively blocks ultraviolet (UV) and infrared (IR) light, which can interfere with color accuracy and introduce unwanted reflections or lens flare. This is particularly useful for Blackmagic cameras, which are sensitive to these wavelengths, especially in outdoor or high-contrast environments.
2. **Improved Color Accuracy** By removing UV and IR light, the filter helps maintain true-to-life colors, reducing the need for heavy post-processing corrections. This is beneficial for cinematographers and videographers who prioritize natural-looking footage.
3. **Reduced Lens Flare and Ghosting** UV light can cause lens flare and ghosting, especially in bright scenes or when shooting through glass. The IR component of the filter also helps minimize these issues, leading to cleaner, more controlled images.
4. **Compatibility with Blackmagic Cameras** Blackmagic cameras, such as the Pocket Cinema Camera (PCC) or URSA Mini, are known for their high dynamic range and sensitivity to light. A UV-IR filter ensures that the camera captures the most accurate representation of the scene without unwanted spectral interference.
5. **Durable Construction** Hoya is a well-regarded brand for optical filters, and this particular model is made with high-quality glass and a metal frame, ensuring longevity and resistance to scratches or damage.
6. **Easy to Install** As a screw-in filter, it fits directly onto the lens without requiring additional adapters, making it convenient for quick setup and swapping.
7. **Affordable for a Professional-Grade Filter** Compared to some high-end specialty filters, the Hoya Y1UVIR077 offers strong performance at a reasonable price point, making it accessible for both hobbyists and professionals.

### **Cons**
1. **Potential Color Cast in Some Scenarios** While the filter is designed to block UV and IR, some users report subtle color shifts (e.g., slight desaturation or a slight blue tint) in certain lighting conditions. This may require minor adjustments in post-production or while shooting.
2. **Not a Panacea for All Lighting Issues** While the filter helps with UV and IR, it does not address other common issues like lens vignetting, chromatic aberration, or flare caused by other factors (e.g., backlighting). Additional filters (e.g., a ND or polarizer) may still be needed for specific shots.
3. **Limited Use in Macro or Close-Up Shooting** The screw-in design means the filter sits at the front of the lens, which can reduce working distance when shooting close-ups or macro photography. This may not be ideal for subjects that require extreme close focus.
4. **Potential for Reflection or Ghosting in Extreme Angles** Although the filter reduces flare, some users have noted that in very bright or backlit scenes, reflections or ghosting can still occur, especially if the filter is not perfectly aligned with the lens.
5. **Not a Substitute for Proper Lens Care** The filter does not protect the lens from dust, moisture, or physical damage. It should be used in conjunction with a lens hood and proper cleaning practices to maintain image quality.
6. **Size Limitations** The 77mm size is standard for many lenses but may not fit smaller or larger lenses without adapters. Users with non-standard lens sizes may need to invest in additional hardware.

### **Conclusion**
The **Hoya Y1UVIR077 UV-IR screw-in filter** is a highly effective and practical choice for Blackmagic camera users who prioritize color accuracy, reduced lens flare, and minimal spectral interference. Its ability to block UV and IR light makes it particularly valuable for outdoor shoots, high-contrast scenes, or any situation where natural color representation is critical.
However, it is not a universal solution users should be aware of potential minor color shifts and the need for complementary filters in certain conditions. For most cinematographers and videographers working with Blackmagic cameras, the benefits outweigh the drawbacks, making it a worthwhile investment.
### **Recommendation**
If you frequently shoot in environments with strong UV or IR light (e.g., bright daylight, reflections off water or glass, or scenes with artificial lighting that emits IR), the **Hoya Y1UVIR077 is highly recommended**. It is especially useful for Blackmagic cameras, which are sensitive to these wavelengths and benefit from cleaner, more accurate footage.
For users who primarily shoot in controlled indoor environments or do not encounter significant UV/IR issues, the filter may still be beneficial but is not strictly necessary. In such cases, consider whether the cost is justified by your specific shooting needs.
Ultimately, this filter is a **strong, cost-effective option** for improving image quality in demanding conditions, and its ease of use makes it a practical addition to any cinematographer s toolkit.
This filter has some blemishes on the glass that are hard to photograph - there spots and a couple scratches. I have not noticed it an effect on image quality though. This filter blocks both ultraviolet and infrared light - essential for cameras that don't have a sufficient IR Cut over the sensor.
