Works very well, great quality thanks
Works very well & is easy to use.
The Drama Polarizer Filter is an excellent accessory. Whether you use it by itself on the iPhone or by attaching it to the Sandmarc Wide Angle (16mm) or Telephoto (60mm). I have used it all three ways. The improvement in the resulting photos is a blue sky instead of a blown out sky, shots that include foliage show their true color without distracting sunlight reflections. I have found using this filter can turn an ok photo into a great photo.
I love the lens. It filters out blinding light and really brings out the detail of the scenes I take videos of as well as the pictures.
