Accessorio utilissimo per fare foto subUnico limite è la potenza del flash della macchina fotografica

Really good! Great alternative to action sport cameras. Good battery development and sharp image in 4K. Very nice!

I found the Dragon Touch Vision 3 camera to be as good as any of the other well known cameras. Right out of the box it was very easy for a non-techie to start using. This camera is user friendly so that you don't need to spend a lot of time figuring out how to use it. You can start taking video within a few minutes.

まあ使えています。ただ、ＬＥＤの光量に依存するから離れるとダメみたい

Mechanically it could be smoother, but it does perform excellent polarization filtering!My camera auto focuses very well with THIS filter!(Previously I bought a AGFA brand filter that was HORRIBLE!)

I have been using this filter primarily to get rid of glare in my webcam setup so my requirements may not be as stringent as for more classical applications. Compared to a Nikon filter I have (of a different size, for a different lens), the polarization effect is a bit lower on the Tiffen, and it also lets through more light. Contrary to some comparisons I've seen online though, the Tiffen for me produces a warmer picture than the Nikon.
