Sometimes it's the simple ideas that ultimately change the world. Those who often change filter certainly has sworn not only secretly, if you screwed and screwed in a light stress. In solving one set of Xume however a thin, intermediate magnetic ring into the filter thread, through which "stick" then the filter easy to leave the ring. Simple and practical. Even better would be if these could establish such a system as a vendor-independent standard, but probably because of the patent already Xume stand against it. But even if the idea of ​​"free" might be, is probably the major manufacturers anyway not agree on the polarity of the magnet and the customer would again have two competing systems of choice;) Currently, the adpater only available for 77mm and the smallest kit costs already around 50 U.S. dollars. We therefore hope that this is not something hefty price scare too many customers and the adapter by strong demand in future something fall in the price. After all alone for the ND-filter, which can now move on DSLRs so quite often does, the Xumes a true blessing.
