I am afraid that I must be pretty careful that I do not at some point davonflitzt the thumb grip times unintentionally. First "security measure": I have fixed a piece of paper in the hot shoe before I pushed the thumb grip. Now he sits stalwart. Because of this high price, I would not like to lose part of all long nose.
An interesting how gratifying Note: The thumb grip fits perfectly on the Fuji X-E1!
Conclusion: 5 stars and recommendation
