HoyaHUVX077 77mm UX UV Camera Filter

It is a good filter

55mm Hoya UX, UltraViolet filter. A good UV/protection filter that doesn't impact the image quality: no loss of contrast and no perceptible reduction in resolution. I'm sure at this price point there are some caveats but for my purpose (as protection for a Sony 35mm, £500 lens) it works perfectly. I would buy this brand again.

Very well made and optically fine as far as I can tell, feels really well put together unlike some cheaper brands. However Hoya's claim that this has a "slim frame" is laughable and misleading. It has exactly the same frame as filters I have from the 1980s and is just not slim compared to others I own (B&W for example). Not a particularly big deal but if you are expecting one of those super slimline filters - this isn't it.

The filter does exactly what it is supposed to do, I've had absolutely no isses regarding picture quality or degradation. It comes off easily, I've had others that once they've been on a while stick, but so far this hasn't.

Does the job of protecting your shiny new lens from grit etc 😀Threads were a bit thin for me but I've not experienced the lens cap popping off. Good quality and pics, with it fitted, are nice and sharp 😀

Sharp for my RF 24-105,but it's slightly scratched after a week or so, (I believe the plastic lens cap did that) a bit annoying but this doesn't affect the picture quality at all though.
