I'm looking at getting a Sigma EF-610 DG ST but a reviewer on Amazon said it literally takes minutes to initially charge. Can anyone speak for this?

Thanks!!

No-one has mentioned any recharge or cycle delay time issues in the reviews of that flash on Pentaxforums.

If an electronic flash has sat unused for a lengthy period the capacitor may need to be "reformed," which can take quite a while. Possibly the reviewer's unit had sat in a warehouse for months, but after the reforming the unit, if used fairly regularily, shouldn't take any longer than usual to recharge.

I have a 2-year old EF-610 DG ST, which I just powered up. It was ready to fire in 14 seconds, and the batteries are not new.

I haven't used my EF-610 DG Super for a couple of weeks and switched it on to test. It took 8 seconds for the ready light to come on. Recycling after a full power test on GP Recyko batteries that haven't been charged for a couple of months took 5 seconds. In normal use on the camera it recharges in an instant.

I have the ST's big brother, the EF-610 DG Super. It has been sitting for several weeks with a used set of batteries. It took 11 seconds from ON to ready .... It DID take longer when I turned it on the first time, but not 'minutes'. If after a half-dozen test shots to load up the capacitors, and you replace the batteries with another good set, recharge time doesn't drop from minutes to seconds, I recommend doing an in-warranty swap.
