Nice video. I got a PL filter, UV filter, wide angle lens and a telephoto lens just like you. I find with the telephoto lens it’s a little blurry don't you think? Especially if you need to zoom in. It hasn’t been the most popular accessories I’ve used for this camera

You can really notice the different with the UV filter when you tested it the way you did. I found it difficult to tell what it actually did so its one of those I never actually used. But now you’ve changed my mind

It really does spoil the videos doesn't it unless like on this video you make your own letterbox cutting the top and bottom from the video. But sometimes it could give a nice effect. like the link you gave me en.wikipedia.org/wiki/Vignetting

Very good video, your composition shots are amazing!

Looking at the comments you made i noticed you have a Wideangle 0.65X. I currently have a Camex Digital Wide angle lense 0.45 X 37MM and it leaves a horrible dark line around the edges of my footages, does yours? if not i shall be getting those soon.
