Protection for the expensive lens

One can think about filter what you want. For years, I use it as a protection for my glasses, it was already too analog hours so and has even now not been changed. I can understand the arguments of the "other side" when speaking out against glass filter as a lens protector (optically effective interfaces, damaging the front lens at break, etc.), but just feel more comfortable if I have a on the expensive lens.

This one is characterized by an excellent finish, very low height and the comparatively low price. So it is hardly noticeable, even the lens cap reaches well into the threads and is secure.

For the 40-150 PRO in my view an indispensable accessory, buy rating and 5 *.
