HI, anyone have problems with the recycling time with the 580ex? Lately the flash has only been firing for the first shot and then it doesn't fire for 2 or 3 shots after that! And I always put brand new batteries in them (duracell, disposables). ANy others with this problem?

Nope. Is it firing full power? Is it on the hot shoe or remote? Are you using a battery pack?

Try using rechargeables.

I have heard they are much better for this type of application and it will save you a lot of money in the long run.

What's the timing between the shots? If the flash is anywhere near full power it can take a few of seconds to recharge when using non-rechargeables.

Hi Joanna - sorry to hear about the problems. By any chance does it behave that way with the rechargeables? Perhaps you got a weak batch disposables? I used disposables initially but didn't like the slow recycle times once the shooting got busy, and was much happier after I changed to the rechargeables. - Stu

thanks everyone ! Which rechargeables do you recommend? It definetely wasn't the batch because it has happened to the last couple of batches of batteries. It is connected directly onto the camera and I don't have a battery pack.

THanks,!

PowerEx from www.thomasdistributing​.com (external link) with Maha chargers. Also get yourself a CP-E4 battery pack, they make a huge difference too, and they're cheap at $150 or so.

Lloyd recommends the C9000 (external link). personally i'd rather have an 8 cell charger so i'd get the C800s (external link). The 801 version puts out more current and charges faster, but slower chargers are better for your batteries.

I am going to assume you are new to flash, so this should not be taken as an insult...

Flash output is like a bucket of water....if you empty the bucket it takes more time to fill it from the small hose. So if you fire flash at a close distance, only a small amount of water is drained and you can fire again and again, until someone tells you to stop draining the bucket because it needs to be refilled due to low water! If you dump all of the water (flash output at full power) you cannot fire again at all, because the hose needs to fill the bucket once again! It has nothing to do with whether the batteries are fully charged or not, it simply has to do with an empty bucket needing refill.

im not new to flash but thanks for the explanation. my problem happens right at the beginning of a shoot so it shouldn't need refilling that quickly.

You haven't told us how long the duration between shots are that you are trying to shoot. Recycle time is about 6 seconds if you are firing the flash at full power.

Yeah, good quality rechargables are the only way to go.

Let me jump on the bandwagon, too. Any brand of NiMH rechargeable will beat the socks off any brand of non-rechargeable. I prefer the so-called hybrid batteries because they hold the charge for a very long time. I've used fast and slow chargers, but I now use Maha (Powerex) MH-C240W chargers and absolutely love them. Any model of that brand would be excellent. They are much easier on batteries than the rapid chargers you can get in your local store. Charge time is one - two hours and they work on both 110V and 220V systems, which is important to me since I get out of the good ol' USA every now and then.
