Customer Reviews

A great flash, but make sure this is what you need.
Bigger is not always better. The more you pay for a piece of camera equipment does not necessarily mean you will get more out of it than a less expensive alternative. These are two axioms that I wish I could learn someday, but I guess some lessons have to be learned the hard way.

This is a great flash, don't get me wrong. It's a 5 star flash--if it is what you need. I bought this thinking it was what I needed but as it turns out it is too big and too powerful for me. It is extremely large, powerful, and top-heavy. I sold it back on the used market and picked up a 430ex which comes in at almost half the price. The 430ex is also around half the weight/size but still packs a good 60-80% wallup of the 580ex II. For me, this has been ideal. The 430ex provides enough flash but not too bright, and it isn't top-heavy or attention-grabbing like the gigantic 580ex II.

If you are going to be photographing celebrities, people who are far away from your camera, or other situations which call for a very powerful flash then this is the flash for you. If you are looking for more of a wedding or cocktail party flash, then I believe the 430ex is the flash. It is hard to tell from the pictures just how different the sizes of the two flashes are, so I didn't know the 430ex was such an ideal size compared to the 580ex II.

While I can't say anything bad about this flash, just take another hard look at the 430ex unless you know you need some serious flash-power.

Buy this good flash first before thinking of investing in any lense
This can be had for as low as 350 USD.

After buying, play around with the curtain sync settings, bounce, and diffusers. You'll immediately see payoff in your investment, through quality pictures.

This is really indispensible at indoor shooting.

I also see improvements in battery and recharge time compared with make I of this 580 model.

You cant go wrong with this investment.

A Must Have For Serious Photographers
Although its not that much better tan its younger sibling, its still is a must have for photographers in need of a Speedlight.
