This is a quick post on a set of extremely cheap wireless flash triggers I bought from Amazon UK for about £15. They are of an unknown manufacture, just called LF106 on amazon and come with one transmitter unit and two receivers. The receivers each take a pair of commonly available AAA batteries and can be switched to up to 16 different channels so they can be used when other photographers are in the same area and using the same system. The transmission unit has an in-built battery.
To be honest the build quality is not brilliant – they look and feel fairly cheap, but to be fair, what would you expect for £15. The main point is that they work with my Pentax K-5 and Metz 58 af-2 flash. I couldn’t find any reference to this type of trigger with my camera and flash combination before I bought them so it was a bit of a gamble as to whether they would work, but this post is to confirm that they do. Of course they are manual only – they simply trigger the flash. Because there is no ttl information passed back to the camera you need to set the flash power for the aperture, iso, distance etc you are using rather than rely on the camera to do it for you. For my particular application (macro photography at very small apertures to maximize depth of field) that is fine and I’m having fun trying them out. I hope to post a few pictures I’ve taken with this setup in a few days.
Update May 2014:
I have recently used these wireless triggers on my Sony Nex 6 with a National PE-387S flash and can confirm that they work. I was a bit worried at first that the switching voltage used on the flash or the radio trigger would be too high, but I used a DVM to measure it and the National PE-387s was 10.0 v and the radio trigger was 3.5 v. Once I knew this I felt a bit happier about trying them and fitted the radio transmitter to the Nex and the receiver to the flash unit and they fire without any problems. I haven’t as yet tried the flash mounted directly on the Nex but at only 10v it should be ok.
Obviously YMMV so check your flash voltage first.
