For this filter, I must say that the purchase is worthwhile even in this proud purchase price and I can continue to have a clear conscience.
The filter affects the recordings and their quality at the Canon 50mm F1.4 at all.
The colors are not washed out and the focus does not suffer from the filter attachment.
At the filter itself, everything is meticulously crafted. The thread is accurate and that the wording of the glass wobbles no, everything budge.
