Have ordered after a long search, the filter After brief tests, I am very satisfied.
The feel is great, grab on with value and the threads are smooth right away.
In addition, real practical accessory is, the filter container is made of solid aluminum and if your filter as I is often used with StepUp-rings of the lens cap to the correct size and class.
Have tested the filter on a Sony A77. Works with AF alone, also the LiveViwe on display even works with ND3 filter without problems. Using a combination of Nd 3+ ND1.8 comes eg. the A77 is no longer really cope.
Register here comes in too little light - here you can define in advance all parameters and then install the filter.
The ND3 filter photos, for example, I open aperture (1.8) and 8-10 seconds exposure time possible.
Really great effects can be achieved with running water.
