The first ordered the filter came into parts disassembled with me. Threaded frame, sealing and lens individually. No original packaging, filters can filter for too large. Brand Name be seen neither on the product nor on the packaging. So all went back with a request for resending of a new, functioning Delamax filter. The replacement arrived quickly. But again NoName filter in an already opened NoName packaging that is too large for the filter. This time, the filter components were interconnected, but obviously needed. The filter has surface damage and contamination. In my view, he was already on multiple cameras.
Even at the price I expect a clean new product, if I buy a new filter. Therefore, the replacement is due immediately.
