Flash is slow with rechargeable batteries

I don't know if this problem is specific to the S5 or not...

I've found that the flash takes a couple seconds to warm up with rechargeable AA batteries vs. regular disposable AA batteries. Has anyone else experienced this? I'm using Duracell DX1500 NiMH/1.2V/2000 mAh batteries with the 15min. charger.

I was doing some research on this and saw this on wikipedia: "The older NiCd battery chemistry can supply a higher current than typical NiMHs, so NiCds are commonly used to power model cars or other relatively high-current-draw devices. New NiMH AAs designed for high current applications are beginning to become available. These use different construction and have lower capacity (1400–1600 mAh) than the highest capacity NiMH batteries. A newer form, low self-discharge NiMH batteries, are sold precharged and ready for use."

So are the batteries I'm using not good for digital cameras?

That's fine. Some people use something considerably higher than 2000mAh but it won't effect the flash recycling time too much. 2 seconds is about the right precharge time for that camera. (you have to remember the batteries are powering the flash and the camera - not just the flash) - and even using a full size flash the times won't be much less - on intial powerup anyway.

Cheers.

Thanks low orbit, so I guess it depends on what you plan to shoot? Use alkalines if you plan to shoot low-light and rechargeables for daylight?

I'd been using my old S60 before I purchased the S5 and I'm used to the flash going off immediately when taking a shot.

No, never use alkalines in a digital camera - unless you don't want them to last too long. If you want the performance of a dedicated flash - just get one.

As for your last comment - it sounds like you're getting a delay after the shot goes off? If that's the case - make sure you haven't got it set to rear curtain sync - to fire near the end of the shutter.

Cheers.

Looking at the documentation, it shows the Speedlite 220EX, 430EX, 580EX & 580EX II, and the HF-DC1 as compatible. But when I go to the Canon website and look under the Accessories for the S5, it only shows the HF-DC1. Any idea on the discrepancy?

Thanks again!

Pass, but I know that the 430EX and the 580 can be used - I assume the others can as well.

Cheers.

Question?
If I ad a digiflash to my camara do I have to change my settings. I just purchased one over the weekend works good when I do a test, but not when i take pictures.
Thank you.

Hey Cheeka ... which flash and which camera model? Posting in the flash forum (with these details may help you). I'd assume it should just pick it up and go if it's a compatible one.

Cheers.
