As expected from a brand like Tiffen these filters are great! I've found that some M2P filters are either too tight or too loose. Surprisingly, the installation appears to be identical to the factory lens cap. I didn't notice any excessive vignetting, the color reproduction is good, the photos/videos are clear. I think the only downside might be the durability of the case over the long term. Also, they are superior to other filters I own. I'm glad a legit REAL photo brand makes filters for M2P.
