Hey guys, I'm fairly new to photography and I'm now moving towards flash photography. I don't plan to use studio lighting yet, that seems to be down the road. I plan to pick up the 580EX II and a few books soon to try things out and see where that leads me. I have been following www.canonrumors.com lately and I notice that there's a speculation that a new flash will be introduced.
Now this is what I've learned. Generally, camera bodies are upgraded generally around 2 years, and lens average much much longer.
How often are flash units upgraded? The 580ex II seems to have been out for three years(2007) and I was wondering if it was time for the 580EX II to be replaced? I'm not too sure the life span on these flash units.
Should I wait or see what's going to come up at Photokina?
