M54 2インチフィルター引き出し

It works flawless! No light leaks whatsoever. Just great!

M54 2″ Filter Drawer

It most definitely does NOT prevent light leaks! In fact it is worse than other brands. Nice strong magnets sturdy build and compatible with zwo cameras as well but plenty of light passing through.

This is the perfect filter drawer for my Touptek camera and Sigma lens. Excellent build quality too.

Good product, only to thread-in and -out a filter is difficult. The height of the framing is too high.
