Just a quick mini review
Firstly the service from SRS Microsystems was top notch. I ordered in the afternoon and the flash came the next day.
The flash itself feels like a nice product. Much better build quality than the Jessops. Buttons feel good and the flash is a decent size adding to the solid feel.
It features a GN of 48, built in reflector/diffuser and wide angle (18mm) convertor. The head tilts up to 90 degrees and down 7 degrees to help with closeup shots. It also swivels. A button on the side locks the flash into place in the standard forward facing position.
Somthing to note is that the head does not stay in position with a GF Lightshpere attached
The flash has P-TTL modes and TTL as well as manual with power increments, etc. I've not tested everything yet but so far so good. It also charges silently which is strange when you are used to the whiiiiirrrrrrrr. A nice bright green button lets you know when the flash is ready though.
