PM Circular Polariser Standard 37mm Filter

I was skeptical about polarizing filters, but this 37mm one cut the glare off my car's windshield beautifully in bright sunlight. The build feels solid and it screws on smoothly without any wobble.

Took a few shots with this filter and the colour saturation definitely improved, cutting down glare nicely on a sunny day. The threading felt a bit tight screwing it onto my lens, but it works fine once you get it on.

I've been using this 37mm circular polariser on my vintage camera and it cuts reflections nicely on water and glass. The threading is smooth, though I wish it came with a protective case. Still, it does exactly what a polarising filter should do for a fair price.
