daytime full ok

I have the filter now about 6 weeks to a 35mm lens Niko. As a protection for the lens it is perfectly adequate and has no adverse effects on the recordings by day. Directly opposite the sun you should not anyway but if there is only in really bad times reflection angles. So you can not complain at this price!
At night it looks not so good because you have to be careful all right that there are no reflections of any lights or other light points. If you play it safe should you unscrew it.
Overall, I am satisfied, and the glass is serving.
