Annoying thing was that the front portion of the bag (the lens) is very rigid and it is the film of the bag permanently while shooting with a finger above and a press on the lens down so did not have the wrinkled edge in the image and the image also was sharp. Is not directly a disadvantage as larger lenses so can be accommodated.
Worked reasonably well overall, even if you had to make an effort.
4 stars easy, inexpensive part, Camera healing. What more do you want. Especially for the price.
