I have an HVL20 on my A900 to trigger my HVL42 off-camera. It works well, and is a lot of fun. I'd like to get another flash for off-camera use, and I am wondering if another HVL42 is the way to go, or whether I should splash out on an HVL58.
With the excellent little HVL20 as my on-camera flash trigger (I'm pretty sure it can't be used off-camera), I don't need the HVL58 to perform that task. What I don't know is whether the HVL58 will still be able to offer its 'ratio' function with the HVL42 when used off-camera. It would be useful if it could, but does anyone know?
