Description

Universal 37 mm CPL filter especially for dashcams and other cameras. This CPL filter prevents annoying and harmful reflections in images from, for example, your car dashboard. The filter acts as a kind of Polaroid sunglass for the lens. Especially in sunny conditions, a CPL filter can significantly improve image quality.

This filter consists of two parts: the holder and the filter itself. You stick the holder around the lens with the thin double-sided tape provided and simply screw the filter onto the holder. This makes fitting and removing the filter a breeze.

Note: The opening for the lens on the holder is 20mm and around this is a circular double-sided tape of +/- 5mm wide (see photo 2). To fit the filter over the lens, there must be sufficient surface area around the lens for this.

    • The filter adapter is a bit oversized for the small lens.

    • Really works against interference.

    • Seems fine to me, no idea if it's worse without a filter.

    • Worthless product with amateurish fixing using double-sided tape that quickly comes loose again. Definitely not a suitable filter for my dashcam!

    • I returned the CPL filter because it did not block sunlight. Previously, I had bought a CPL filter from Allcam for the same reason; back then I had an Azdome dashcam which I had no success with and could not return. I have an A610-w Kenwood dashcam, and on Allcam's website I saw a 37 mm CPL filter in green colour, so I thought it was a sun lens filter. That's why I ordered it.

    • The delivery was quick and the packaging was very good during transport. The filter has achieved a visibly excellent result, which I am very satisfied with. Thank you very much.

    • Doesn't fit perfectly on the Redtiger F77 (adhesive ring), but the diameter fits the camera lens. The dashcam now has a much clearer picture. Great, I would buy it again.

    • Not very convincing despite all the reflections. Expensive for what it is.

    • Fits perfectly on the Azdome GS63H Pro. Reflections are gone and the image is better. 👍🏻 The CPL filter including adapter gives a quality impression.

    • The filter can be mounted well. However, the vignetting, i.e. strong shadows in the corners of the image, is very large. I have not yet found a solution to this problem.

    • I give 3 stars because I have not yet been able to try the CPL filter. I assume the CPL filter is for the Azdome GS63H Pro Dual. The problem is that you have to stick the CPL filter onto the lens. Next month, on 26 April 2024, my purchased dashcam will be installed and connected to the car's fuse box.
