I recently purchased a lens with a 58mm thread size, so I was out looking for a UV filter to protect my investment. One of the first things I learned about photography is that it is always cheaper to replace a filter than a lens due to an accidental scratch or abrasion. When you are out and about, you also don’t have to be paranoid about wiping off the surface of a filter, which often happens when you do not have the time to do it properly with a blower or a cleaning cloth.
I have K&F filters on almost all of my lenses and have not seen any noticeable issues in using them. This package included a cleaning cloth, lens cap and a cap lanyard. Personally, I like to keep my OEM lens caps safe at home. If you sell a lens, it will always look a bit more attractive to most buyers with the original cap be it Canon, Nikon, Sony, etc.
The lanyard is orange colored and very well made compared to others I have. Regarding the cleaning cloth, you can never have too many of these on hand. All of this was packaged in a clear hard plastic case which could be used for other items.
For the price, I consider this to be a very good package to buy.
