In the current model of lightning snapped in a shoe, is held securely u. Can be removed via push-button again. Control really gives remarkably good results in my X100s. Actually I use the flash only rare, but must now admit "increasingly". This is certainly also on the compactness. Fits in your pocket. The charging time with new batteries is up to full charge 11-12 sec. Since the camera but usually can not retrieve the full power for about 6 sec. Be flashed. The slave function I do not use. The flash has no swivel function does not bother me. Mostly I use it outside to brighten. But can those who want the lightning indeed keep up with the slave function in the hand. But who should take better flash a lot indirectly the EF-20. The yes some Euros cheaper. But one must also bear in mind the LZ 20 by bounce shooting yes no great illumination has. The processing (metal case) is really great. Strong buy recommendation
