I really have nothing positive to report about this device. The range is catastrophic, at this distance, I can really use my arm also. If I go further afield, I have no reception. The word "far" is here therefore not really appropriate application.
If he then still triggers times, I find mostly against blurred images, the AF is not really a. Also regarding the image quality is therefore not recommended that remote release.
Likewise, I have the remote release maybe operated 50, if at all. Since it no longer works. I do not know if it already is by so little use of the battery, but since I will no longer use the device, is a replacement of the battery for me no longer needed.
If there was the possibility to give zero stars, I would make use of this selection. Unfortunately, this remote trigger was a real bad buy!
