Hello everyone. I'm so glad I came across this forum as a result of enrolling in my online photography course. It is truly awesome so many thanks to all who have contributed! As a beginner in photography I want to purchase an external flash for my Sony A580 camera and a second lens ( a good portrait lens). i need some professional advice as I don't want to waste money on something that isn't going to help. If you could post a reply I would appreciate it. Many thanks
