Hi,

I see a lot about the variable NDs not being very good (although some disagree), but are their UVs any cop?

They claim they use the same supplier as other companies, but if it is true are those just poor quality companies?

* No UV/'protective' filter can improve image quality on a dSLR.
* All UV/'protective' filters will cause some degradation in image quality.
* The seriousness of this degradation tends to decrease as filter cost increases.
* Good filters will cause degradation that is not noticeable under most conditions.
* All filters, even the best, will cause noticeable degradation in some conditions.
