    Hello all ...I bought my canon 550d a while ago and purchased the nissin external flash along with it
    It used to work well till some time ago when it started giving me trouble .the red light does not turn green after switching it on most of the times and even if it does ..after a single flash it turns red again and does not green again..am using rechargeable Sony cels and have made sure they Are always charged ....please help
    Thanks

    You need to eliminate the possibility that one of the Sony cells is bad, which is quite likely with NiMH cells, especially if they are not used very often. Just get a pack of four alkaline cells and see if that fixes it. If it does, replace the Sony cells with Sanyo Eneloop or equivalent.

    ...or just keep using fresh alkaline batteries. Rechargeable ones are far too much od a slitter for me. Much easier to carry a spare pack of normal ones.

    Eneloops consistently outperform alkalines. They hold their charge extremely well and give a much more consistent cycle time over the life of the charge than alkalines. Alkalines have significantly higher internal resistance than Eneloops, so despite the higher initial voltage are unable to provide a high enough current to give short recycle times. Tests show an initial flash cycle time nearly 25% slower with alkalines, while by the time you've nearly exhausted the cells the gap has widened to nearly 50% as the on-load voltage drops off quite badly.

    Hello I tried putting new alkaines into the flash but it did not even show the red light consistently...I mean the red light blinked a bit and went off again ..with my Sony Niamh ones at least it used to switch on to red and occasionally fire Sad

    Oh dear! It does sound like there's a problem with the flash then. Unless it's still under warranty it would most likely cost more to repair than a new unit, at least in the UK.
