A good quality UV filter
This filter is from K&F Concepts' premium filter range. The company also offers a budget range. I have bought several filters and other gear from K&F, as they represent good value for money.
At AUD 78, this premium filter isn't cheap but is more affordable than premium filters from different brands.
I like to find a sweet spot between price and quality. Doubling the price doesn't necessarily make something twice as good. As a non-professional, punching above my weight and using extraordinary gear, I am satisfied with good-enough filters. At the very least, these K&F Nano filters are good enough and plausibly far better.
I installed the filter on my Sony FE 40mm f2.5 (see the attached images), which has a 49mm thread. One can fit filters directly on the lens, with the lens hood detached, or directly on the lens cap. I have chosen the latter because I want to retain the hood.. I probably don't need a UV filter on this lens as its unusual lens hood encloses the glass. The OEM lens cap fits snugly in the filter housing, so I'll leave the UV filter on.
