Manfrotto XUME Adapters
From £10/$11 www.manfrotto.co.uk
Not only can magnets streamline flashgun modifiers, Manfrotto has found a way to combine them with the humble screw-in lens filter. Xume two-part adapters enable a filter to instantly snap onto your lens; simply screw in one half of the adaptor ring to your lens’ filter thread, the other half to your filter, and then let the magnets do their thing. The adapter’s low-profile design helps avoid vignetting on ultrawide optics.
First impressions_ While screw-in filters are less versatile than their square counterparts, these adaptors certainly make them easier to use.
