Q
What makes this filter kit "HD Ultra-thin" and why does it matter?
Answer Question
A
The "HD Ultra-thin" design refers to the filter's slim frame, which is only 3.3mm for the CPL and 3.2mm for the MCUV. This is crucial for two reasons. First, the ultra-thin design helps to prevent vignetting (darkening at the corners of the image), especially when using wide-angle lenses. Second, it ensures the filter doesn't interfere with the lens cap, making it more convenient to leave the filter on your lens for quick shots.
