Hoya ALPHA CIR-PL 49MM

Great filter. It came in good condition, and has worked exactly as I expected it to. I would recommend this filter to anyone who does a lot of photography in harsh sunlight, who wants deeper blue skies, or wants to remove reflections from water or glass. The only thing that I was slightly disappointed by was that it hasn't cut out all reflections from the desired surfaces, but I'm not even sure that that is possible with a circular polarizer. If you need certain reflections completely removed, I would recommend looking into linear polarizers.

This product (49mm Hoya Circular Polarizing Filter) was delivered quickly and arrived in good condition. After figuring out the proper way to install the filter on my X-100f, I tried out several photographs. So I haven't had a big photographic trip to use this on yet, but it seems to work really well, with no color distortion, the elimination of all different kinds of reflections, the slight intensifying of natural scenes (fewer reflections from leaves), and the increased clarity of the sky (fewer reflections off of the particles in the atmosphere). The filter can also reduce reflections off of people's faces, which can be helpful at time. One problem, however, is that none of my lens caps fit with the filter on. Perhaps this is normal with filters. But it would be nice to have a lens cap that fits over screw on filters.

This was my first filter purchase for a Canon SL1 paired with the latest version 50mm f/1.8 STM lens. I shoot a lot around water and bright blue skies so I figured a polarized lens would be a good investment. The Hoya 49mm alpha CP Filter comes in a solid package that was just a bit scary to open, but once I pried it open and had the lens in my hands, it felt solid enough on its own. I had to be very careful not to cross thread the filter onto my lens, but I'm sure that's a given. By hand, it was a little tricky since the threads are super small, and the band that actually tightens the filter versus change the polarization angle was also very narrow. This caused me to unscrew the filter my first time playing with the polarization, luckily it unscrewed into my palm rather than onto the ground. After that, I took a little more time to snug it on the lens firmly, and have yet to feel it loosen up at all aside from a test to make sure I hadn't overtightened it.I would definitely buy this again, it does what I wanted it to do: cuts down on reflected light coming off the ocean.

Such a big difference! I took two pictures of a home, one with the filter and one without. The amount of detail that the sun was washing out was a lot. Love it. I used the filter on my Sony 50mm f1.8 lens.

Kinda hard to take it off from lens. And I feel I received an used copy that has use of signs on it. At least, this filter gets the job down.

Does just what it’s supposed to. No complaints.

Good fit with the Nisi 49mm filter adapter I use. Screws in smoothly and rotation of polarizer is firm and stays where it's set without being sticky or tight.

Fits precisely and turns smoothly. To my eye I can't see added softness in my images. Of course I am not a pro, but do appreciate keeping my images as sharp as possible.
