Good UV protection filter with lens cap
First of all: I'm not a fan of always using a lens with a UV protection filter. No matter how good it may be: Any air-glass surface in front of the lens impairs imaging performance and has an effect on the optical design of the lens. It may be that this is not always visible, but in borderline situations (e.g. stray light), this can lead to blurring, poorer contrast or flares. Due to the hard coating of the front lenses, this protection is also usually unnecessary.
However, there are always situations in which mechanical protection of the front lens is more important than the disadvantages described above. Then the UV protection filter from K&F Concept is a good choice, because its nano coating (18 layers!) At least keep the inevitable flares within limits. The included lens cap is ok so far, it meets the usual standard here.
One more tip: Nano-coated filters tend to magically attract dust. Care should be taken to ensure cleanliness here so as not to adversely affect the contrast and sharpness of detail.
