recently invested in this set of ND filters, and I couldn't be more satisfied with the product and overall experience. These filters have greatly enhanced my photography, and the included carrying case adds an extra layer of convenience and protection. 1. Quality Filters: The filters provide excellent clarity and minimal color shift. They deliver smooth, balanced exposure adjustments without any noticeable vignetting or unwanted color cast, even at higher stops. The range of ND levels is perfect for varying lighting conditions, from softening bright daylight shots to creating beautiful long exposures. 2. Ease of Use: Each filter is easy to attach. They are magnetic making it simple to switch them in and out without worrying about damaging my lenses. 3. Durable and Compact Carrying Case: The carrying case included with the filters is well-designed and sturdy. It holds each filter securely in its own compartment, protecting them from scratches or dust when not in use. Its compact size fits neatly in my camera bag without taking up too much space, making it easy to carry on all types of shoots. Conclusion: This ND filter set has become a staple in my photography kit, offering both high performance and practicality. I’m thoroughly pleased with the quality, durability, and thoughtful design. This product is a fantastic investment for photographers looking to elevate their work with reliable filters. Currently using them with Voightlander 36mm with Leica M11.
