D30 with new lens EATING batteries !!

[Charlier26]

I have a D30, and just purchased a new Sigma f2.8 28-70 lens. It works fine, but it has been EATING up the batteries. It seems that the battery from full charge lasts about 15-20 minutes of sporadic use. These are brand new batteries. (The old batteries lasted much less). Could the lens have some kind of flaw?

Could the lens have some kind of flaw?

The answer is painfully obvious: Yes.

How is it with other lenses? Does it drink battery for breakfast?

If there is a dramatic difference in battery life between when you use this lens and when you use any other lens then yes, it MUST be faulty.

Have spent 6 hours with my 10D on and shooting, for a total of 2580 shots. I use a battery grip and had 2 batteries in it. They didn't run out! 15-20 minutes is very very poor, I would expect over 2 hours of sporadic use with one battery (I once shot for 4 hours taking over 300 photos on one battery).

If you can shoot for 3 hours with one lens, but less than 2 hours on another then I wouldn't worry. But if it is 3 hours on one lens and 20 minutes on another, then you should return the lens and exchange it for another one. Let us know how it goes.
