Re: Speedlite 580EX II underexposure problem

Thanks to everyone for your interest. I've resolved the speedlite issue.

I use low-discharge NiMH batteries and found their performance superior to alkalines.

Re: Speedlite 580EX II underexposure problem

"...BTW, I do have external battery packs for my old 283's and 285's. They work great. I don't have or even know if Canon makes one for the 580's..."

 

Yes, Canon offers CP-E4 auxiliary battery pack for 550EX, 580EX, 600EX flashes. The earlier versions (CP-E, CP-E2 and CP-E3) all also work fine with any of those flashes. There have been various improvements to the battery packs over the years, but they all put 6 or 8 additional AA batteries at the flash's disposal (the flash still needs to have 4 AAs installed as usual, too). They make for faster recycling and many additional shots.  

 

I shoot professionally and rechargeable AAs make for a lot of savings, after the initial purchase and setup costs. I don't find it any more of a problem to recharge a bunch of AAs, than I do recharging the LP-E6s (or whatever) that power the cameras themselves. Over the years I've accumulated enough chargers that I can recharge overnight sufficient AAs for a full day's shoot. But I also keep a bunch of alkaline AAs handy, just in case.

Good thread. I ased alkaline batteries at one time but when I got more serious with flash my local mom and pop camera shop explained this to me. They also mentioned the Alkalines not only recycle slower but do not have the power low discharge batteries have. That may have been mentioned as well. After getting new rechargeables I never looked back.

 

Also it is a good idea to get a good quality recharger that conditions the batteries.

Re: Speedlite 580EX II underexposure problem

I did speak with two of my full time pro buddies last weekend. Well one was by email. These are guys that make 100% of their income from their camera. It puts groceries on the table. Likely nobody on this forum is in that situation.

One said, "No way." Actually that isn't a direct quote. You can add the explicative. Smiley Indifferent

But the other told me he had switched. Smiley Surprised  It was not Eneloop but was some other brand that I have quickly forgot. I'll have to see him again. He said these charge in two hours but will quick charge in an hour.

 

For now I will stay with my use of regular AA's. I just don't want the extra effort of another thing to keep track of.

Right now I have eight camera batteries to make sure are charged and in good condition. Adding 16-20 AA's to that mix is just something I don't want. Especially when you are talking about pennies. Plus the PITB of making sure you get back home with all of them.

 

And if you have a malfunctioning flash, like all this started out, I firmly recommend you get a brand new set of regular AA's to make sure it is not the batteries. So, dump the rechargeables.

 

 

A lot of Canon stuff. Along with, a lot of other stuff.

Re: Speedlite 580EX II underexposure problem

Interesting, but not surprising to see strongly-held but opposing viewpoints.

I think I will stick with rechargeables. "Chacun a son gout" as we say where I come from.

Re: Speedlite 580EX II underexposure problem

Yes. I'm going to stick with my rechargeables as well. I keep pack of Alkaline as a backup but never use them. I'm not sure about ebiggs friends asseccment based on everything I have read but I live in an each to his own world. Whatever works for you.

Re: Speedlite 580EX II underexposure problem

I have the same problem with my 580 EX and have done similar tests with my flash.  I have multiple flash units and the problem is only with my 580 EX.  Tomorrow I am bringing the flash into the Canon Service Center in Irvine, CA.  I will let you know what Canon claims is the problem when the flash is repaired.

 

I am a pro photographer for over 40 years and would not hesitate to use my Eneloop rechageable batteries in my Nikon or Canon flash units or any other piece of equipment in which the batteries fit.  I have never had any problems using rechargeables.

Re: Speedlite 580EX II underexposure problem

I found the problem to my 580 EX underexposure and I hope this helps you if you haven't fixed your problem yet.  I recently brought my camera into Canon for sensor cleaning and after that came a consistent flash underexposure.  Before taking the camera and flash into Canon tomorrow, I decided to go through everything on the camera again.  I discovered that the Flash Exposure Compensation in the camera's menu had been set to -2.  When I set it back to 0, the camera and flash functioned perfectly.  I have a 5D Mark III but your menu cannot be too different from mine.  Find  External Speedlite Control in your camera's menu, look this up in your manual to find where this is in your camera's menu.  Scroll through the various sub menus under External Speedlite Control until you come to Flash Exposure Compensation.  Set this back to zero if it is not already at zero.  Hope this works for you.

Re: Speedlite 580EX II underexposure problem

Thanks for your interest. I went through the same exercise as you, my settings were fine.

I now get good results, I tend to shoot in manual rather than ettl, sometimes with + flash exposure compensation.

Or you could just put another set of rechargables in to check.  It's not rocket surgery.

 

Your information on rechargables is dated, at best.  NiMH rechargeables offer quicker recycle time, longer lasting, economically cheaper, and creates less waste.   Your claims that it’s ok for the hobbyist, but beneath Pros, is just arrogance.  Do a search for flash battery recommendations and you’ll see evidence of thousands, if not millions, of professional photographers that are using rechargeables without logistic difficulty.  You charge them the night before, put them in a marked case, and it’s no different than pulling out a brand new set of alkalines.
