The filters are mediocre in quality, the price is all but in the green zone. Turning up the filter I need to spend a bit of tact, because the filter to tilt slightly ETAS. They make a not so stable impression and the untwisting sounds scratchy.
The polarizing filter works very well.
At the UV filter, I could see no negative adverse effects on image quality.
The hot filter is unnecessary taste and also actually in RAW photography, as well as the ND filter, I could not make sense to test. A useful accessory is the bag that you can use, of course, otherwise shared versatile! ;)
In résumé a good set for the price.
