Indeed, a simple scratch on your lens does not forgive! So just for that, this is useful.
Bought for a Nikon, this gene in any way the use of the lens cap or the lens hood nikon.
Therefore also the use of "protective" product (scratches, stains, dirt, dust ...), there is also the aspect of the filters. The 3 filters (UV, CPL and ND4) that feels positively on the photo without affected the quality respectively allowing a good UV filter (which altered target and 5% of the shots), reduce the light captured by the lens when taking high light situation, and finally, avoid some unwanted reflections (unwanted) at certain outlets.
In short, for this price, do not hesitate especially well made product, good quality, and allowing both good protection, and also may prove useful in certain applications.
