Clever accessories for smartphone photography with slight weaknesses
The magnetic ND filter from K&F Concept is a great extension for anyone who wants to get more out of their photo and video recordings with the iPhone. The magnetic holder holds reliably, the filter can be adjusted continuously and ensures a beautifully balanced lighting in daylight. A real advantage, especially when recording videos. A dot deduction because the adapter doesn't always fit perfectly with cases with a slightly thicker edge — you sometimes have to shoot “naked”. Nevertheless: high-quality workmanship and very well thought-out. Highly recommended for ambitious smartphone photographers.
