How does a camera show weak batteries aside from just quitting?

Using my *ist I have had some flash issues once in a while which almost looks like the camera (when in auto mode) miscalculated the exposure giving me dark pictures. Than after waiting a bit it shoots a good picture.


Assumed it was my lack of talent, but thought I would ask the group if anyone knew if weak batteries would cause this kind of problem. I use Rayovac 2500NiMH rechargeables and they seem to be fine, but thought I would throw the question out there.

My set-up *ist DL, AF-360FGZ Flash.



Included a Zoo picture not to show the problem but for fun.

Are you talking about the flash batteries or the camera?

I've had trouble with my batteries, discharging by themselves in half a day (according to my DS) and lasting 40-50 shots newly charged (2500 mAh). The first sign of weak batteries was exposure going nuts, soon followed by the "half battery" symbol and then nearly immediately totally empty.

I bought a new set, 2700 mAh. What a difference! After ten days in the camera and a few hundred shots they still show the fully charged symbol, and there are no problems with exposure. So I do believe that your problem is a battery problem, try another brand.

Love your picture! And yes, its been my experience that weak batteries can affect exposure also. The battery indicator on my old DS wasn't terribly accurate (it would show full until right beforethebatteries were discharged)- the K100 is much more accurate. It actually gives you a fair amount of warning.

Use Lithium AAs or CR-V3s instead. They last 1,000 to 2,000 shots and give you faster AF performance.

Weak batteries also cause focus errors, at least with my Sigma lens.

Perfect info. It was the camera not the flash and that is exactly what happens now that I think of it. 1st the exposure seems off than soon after the battery goes right to half gone.

Thanks for the tip.
