Just got a 270EX II, mainly because its small and will be a nice compact flash for my kit bag, to be used on my 50D and my little PowerShots

Im the kind of person that like to bounce the flash, I use 430 and 580 as my main flash units.

The 270 is doing some strange stuff, first picture I took with it was perfect then the next 5 or so the image was dark.

The flash is firing but a very weak amount, its not the re cycle time I'm giving it a good 5-6 seconds between pics.

No matter what setting apart from setting on the camera the flash to be in manual not auto mode. Its not always going off at what I would say should be normal full power.

But what strange is I can have on tripod so the scene is not moving and 3 out of the 10 are not dark.

Even if I fire into a almost dark room, the 430 would fire overtime the 270 only fire once or twice in a 20 images sequence.

Wondering if this thing is faulty, all the review seems so good.

Its the same on my 50D 5D or PowerShot cameras.

That is so dark i would suspect a sync issue. Maybe the weak flash you are seeing is just the preflash and the main flash is not going off at all.

Take a shot with zero flash and see if it matches the dark photo.

Regardless, I'd send it back.

Before returning the unit, I'd fire off several images, similar with what you have done, but with the camera in "P" or full automatic mode.

There are some issues with that unit, some of which are caused by an undersized capacitor that loses charge rapidly when in standby and hence recharges slowly as well. See https://kenrockwell.co​m/canon/flash/270ex.ht​m (external link) for details but scroll down to the "Problem" area.

A good guide for the unit can be found at https://support.usa.ca​non.com …US&searchid=153​0118049696 (external link).

i don't see how any of that stuff rockwell says about the capacitor applies to the OP, and don't see how putting it in full auto or P matters either.

but really i just wanted to post to point out some more rockwell nonsense:

"Problem 3

If you tap your camera's depth-of-field preview button, even by accident as you change lenses, the flash fires off a long, extended full-power burn, which can blind you or damage your vision at close range.

Nikons do the same stupid thing, but at least there's a menu option to turn it off, and newer Nikons default this option to OFF. With my 5D Mark II, I couldn't find a menu option to rectify this defect. The is a safety defect because it defaults to ON, not OFF. (Hint: readers report that this option might be in the WRENCH •• menu, Flash C. Fn. setting 3 under "External Speedlite control," not the flash menu where it belongs.)

In Japan, this defect is called a "modeling light," and pitched as a feature."

lol

whether the feature is truly useful or not is debatable, but that's a steaming load of crap.

Another person that hates Rockwell....Oh well.

Previously you were very quick to say "Regardless, I'd send it back." The purpose of putting it into "P" mode and retesting is simply to verify that the unit can work properly. That eliminates the effect of most of the camera setting that may have some bearing on the flash behavior. So what does it take; 5 minutes to do the test? Do you remember Chuck Westfall, now deceased but formerly with Canon. I met him once and we discussed a refurb 60D I had purchased from Canon (my 1st refurb by the way). When I mentioned that it was pristine upon receipt and only had 40 clicks he said that nothing is ever found wrong with about 2/3 of the returned products. He also stated that a great number of returns, but probably not applicable here, is buyers remorse. A buyer finds DSLR too complex, so they return a camera drop back to a point-and-shot.

Didn't Rockwell admit he uses colorful and not entirely accurate information to boost clicks?


The flash (with fresh batteries) should give consistent results under the conditions OP describes, regardless of camera mode.

There are some fundamental questions that need to be addressed prior to sending the unit back.

That flash has recycle times as shown below:

1) Normal flash: Approx. 0.1 - 3.9 sec. / Lamp lights
2) Quick flash: Approx. 0.1 - 2.6 sec. / Lamp blinks at 8 Hz (with size-AA/LR6 alkaline batteries)

We don't even know what type of battery the OP is using? (Alkaline or a recharageable)

"Quick flash", if enabled only reaches a charge state of 50% but the first flash is at 100%. The Quick flash can be enabled/disabled on the 270EXII by changing the setting at C.Fn-06 Quick flash w/continous shot (Disabled/Enabled).

Thanks for the replies.

Little more info on how and what:

Only use P mode or AV
In this case I use Eneloop also tried my PowerEx Pro, they are all newish and fully charged, they are cells I use on my 580 anyway.

Checked and the Quick Flash is disabled

Three more pics

First one flash not turned on, then turned on. As you see the first flash fires fine, I wait 5 seconds and shot again and as you see the third picture is not right, the flash did fire but lower power.

I can actually repeat this every time, power off flash then the first picture taken with it after powering up is OK, the next few will be bad then I get a one or two good again.

This is a brand new flash purchased last week it arrived with me yesterday, I did clean the contacts to be sure.

Its annoying its from Newegg and the return policy seems a ****, they want restocking fee if I want my money back. This is why I want to see if its something Im doing wrong, but to be honest Iv used speedlites for over 15 years I know how they should work, this one seems bad.

Looks like I need to waste time in getting it to canon for service

Exif shows the camera thinks the flash is going to fire.

Maybe you're counting too fast.

Or just give it 10 seconds to be sure. Disposable alkilines do not recharge as fast as rechargables.

Your profile states Toronto / UK as location so check the warranty where you live. At least here in the States, one has to be very careful about buying through Newegg. There is for instance a 270EXII priced at about $145 but on careful examination the warranty is by Tristate, thus in all likelihood it is a gray market product. As an FYI, Canon USA sometimes won't service gray market products. There is also another 270EXII, supplied by a different vendor and at a higher price $202 but still no Canon warranty. You can go as high as $290, but still no Canon warranty.

The best deal, assuming residence in the States is a Canon refurb at $136 (see https://shop.usa.canon​.com …6rTS3i7GH52RoCx​ngQAvD_BwE (external link)). That comes with the standard 1-year Canon warranty.

Thanks for the info, I was sucked in by the cheaper newegg price, its newegg Canada, the warranty sheet in the box says US and Canada so I hope to have a none grey import. Im contacting Canon tomorrow to try and verify with the serial number
