This is a solid filter. It can be used to create some really awesome photos or videos. Especially videos, I can only imagine the cool effects one can manifest. The filter works well with all manners of lens, I mean it doesn’t go on the lens so you either have to set or hold it, so it’s just about that placement. It’ll work with any camera, I haven’t tried it but I wouldn’t be shocked if it worked with a phone camera as well. Again, this doesn’t go on the camera, you would have to hold it by hand or mount it in front of the camera.
This is also half, so it gives a good effect. This is ideal for those who want to do everything in camera or only lightroom, but if you are someone who uses photoshop, then why bother, you'll have more room to work with in post, and you don’t need this.
The glass is really well built, I mean solid stuff, that alone is enough to get it, and it comes with a carry pouch, a good pouch, no complaints there.
This is where the complaint starts. I don’t know what to use it for, other than taking a photo and then transferring the JPEG files on the spot. If it’s a raw file, you have to process it no matter what, I can just take a moment and transfer it to photoshop and do it there. I’ll even have better control there as well.
Though for videos, it’s a different story. I think for a video this will be a cool effect and will make post production easier. I still have not figured out the logistics if I am making a video, I will have to hold it by hand or I will need a tripod or something to hold in front of the lens, but that makes moving with it a little difficult, unless I plan on using a cage.
At the end of the day, it is a solid built filter that will come in handy every once in a while, maybe. I can’t say I like it too much but I cannot deny what this filter brings creatively, correction, will bring for certain people.
