Hello from new member. Does anybody have any experiences with that flash trigger? -- I have owned a lowly Nex-C3 now for 4 months and I did purchase SLA-10 flash adapter to use manual flash for it. With it there is one serious drawback, Nex doesn't know that there is a flash attached and it is almost imposible to compose a picture when taking pictures where most light comes from the flash. The kit flash works ok, it informs the camera that there is a flash and live view is bright enough. I use mostly manual lenses with flash (Pentax K 55/1.8, Pentax M 28/2.8, Tamron 105/2.5 and Tokina 80-200/4.0). I use the SLA with pt-04 flash trigger as I don't care about flash in top of camera/internal flash. I e-mailed the manufacturer and they replied "1. After insert our transmitter into the camera's smart port, the Nex camera will automatically realize it as a flash, will light up the screen immediately." so this souds promising but does anybody own this? Wansen makes similar one but I think that I like this better (ergonomics, I use camera with left hand). They sell extra receivers for 22 USD and there are some 2.4 GHz 16-channel receivers availlable in ebay much cheaper but I don't know if there work whit that transmitter. I already ordered this as it can't be worse than SLA-10 but I am grateful about any information about that product.
