Shake reduction battery drain

When Pentax first introduced SR in their cameras (Ithink it was the K100D), I remember reading in the AP review that switching this feature on, it was on the back of the camera then, had a big influence on battery drain.
I am wondering if this still applies. Does anyone have a answer to this?






KR,SuperA,MX,MZ5N. Numerous lenses.

I spend all day 9-5 or 6 taking up to 800 pictures at my local karting track and normally only need to swap the battery for the last 1/2 to 1 hour. The SR is left on all day. So I'd say no

Hi Malcolm.


I have a K10 and a K5, can’t say I notice a great deal of difference with shake reduction on or off.


Take care.

Logically, SR must use some power, so it must have an effect on battery life. However, this appears to be minimal so I wouldn't worry about it.

Thank you for your comments. It does look, as John Riley suggests, that battery drain is now minimal. But I don't think that was the case on the earlier models.

VR, OS and IS found in lenses from other manufacturers also use additional power. You need to have powered moving parts for it to work.

I always have it on and marvel at just how long Pentax batteries last in my K20d
