This K&F Concept filter has been only used once or twice, it turns out it was surplus of my requirements that’s why I am selling it. I am the original owner from new, this costed me upwards of £30 from new. It comes with the box. The manufacturer is reputable and sells some other prestigious filters so you can expect quality here. This filter has an adjustment knob which operates simultaneously moving the other knob at the same time - not separately. This filter is ideal for filming and capturing some specific situations. Please become informed on the topic of filters before buying. Buy with confidence I will answer any questions swiftly and assist you with care before and after the purchase. It will be packed and shipped within 2 working days. Thanks.
