Has any one used this Filter, I have a canon 18-55mm, 58dia lens, how good is the picture after mounting this filter?
I think that for the price/value, the Hoya is unbeatable. Keep in mind that it is an 8 stop filter, not 9 stops, as Hoya claims.
I stepped up to the convenience of the Lee Big Stopper, which allows me to compose and focus, as well as get a baseline exposure value, then just sliding the filter into place. The Hoya is not as easy, as it is a screw in. You can still compose and focus, but screwing and unscrewing the filter can become tedious.
One advantage that the Hoya has over the Lee, in bright light, you can see through the mounted filter in the viewfinder. Another advantage, since the filter is 2 stops lighter than the Big Stopper, you can use the Hoya with a speedlight for outdoor portraits, for some added creativity.
Like the Lee Big Stopper, the Hoya ND400 is a glass filter. Though it will create a bluish color cast, unlike magenta color cast of resin filters, it is easy to correct in post processing. I actually like the blue cast, as I use these filters for daytime and water themed long exposures. The sky just looks a bit nicer.
So, if you are looking for a reasonably priced ND for long exposure work, look no further. If you don't mind screwing and unscrewing the filter, look no further. Even though I use the Lee Big Stopper most of the time, I still use my Hoya, and as a matter of fact, I used this one today on my 28mm prime.
