Good UV protection filter with lens cap
First of all: I am not a fan of always using a lens with a UV protection filter. No matter how good it may be: every air-glass surface in front of the lens impairs the imaging performance and affects the optical design of the lens. It may not always be visible, but in extreme situations (e.g. stray light) it can lead to blurring, poor contrast or flares. Due to the hard coating of the front lenses, this protection is usually unnecessary. However, there are always situations in which mechanical protection of the front lens is more important than the disadvantages described above. In this case, the UV protection filter from K&F Concept is a good choice, because its nano-coating (18 layers!) at least keeps the inevitable flares under control. The lens cap supplied is OK, it corresponds to the usual standard here. One more tip: nano-coated filters tend to magically attract dust. Care should be taken to keep them clean so as not to negatively affect the contrast and sharpness of detail.
