Tip filter at a bargain price

Have brought about a month ago my filter set. Have they now can really test, she had on vacation with. The filters are sure to gelichem level as the BW filters of quality. That these filters have a bluish cast, was already mentioned by my outpost, but that's not a Haida phenomenon, but a colored engraving have all gray (ND) filters, the BW's just only reddish.
This Haida blue tint can either neutralize through a red filter, or need to photograph in RAW and make an appropriate white balance. This is especially with long exposure to the ND1000 (event. This is not enough, then there is the ND64 to) important because even the best software no longer receives this blue cast in the handle. This is true in my experience, but only if one leaves the white balance of the camera, rather than to correct it manually.
The only slight downer: The thread is not, unfortunately, the quality of the glasses. Again and again jammed filter which is a bit annoying to the container. By selectively putting the jamming can be prevented in most cases.

Otherwise, I'm really excited, I've already ordered the 62mm-set - can the filter with the small negative point thoroughly recommended.
