AC power adaptor for EOS 20D?
Posted: May 19, 2005 - 12:23pm

Since October 2001 I have used a Minolta Dimage7. It is an absolute battery hog, so I typically use an AC adaptor when shooting indoors and have a nearby outlet. Earlier this week, however, I ordered an EOS 20D and should have it tomorrow (5/20), but now I'm wondering if I should buy an AC adaptor for it also. I know Canon rates the 20D's battery as being good for 400-700 shots, but I'm wondering if this is accurate or marketing hype. I'd rather not have to continue using an adaptor but will if the battery runs down frequently.

20D owners/users: what would you estimate your typical battery life to be for the type of shooting you do and the way you have your camera set up?

(Most of my photo shoots are indoor "studio" shots of scale models. I normally [with my Dimage7] shoot 5mp jpgs or tiffs for publication.)

Thanks for any input or insights.

I purchased the battery grip with an extra battery. I get around 1300 shots off, between JPG and Raw, before the need to recharge... if you are shooting pro you won't be using the built in flash so you should be fine with that.

You will have more than what you need. I've shot a 6 hour event and fired shots continuosly for a canine sports event and didn't even get my battery meter to reach half way.

Plus with the battery grip you will get a verticle shutter button.

Battery Grip BG-E2

Prior to the 20D, I was using a Dimage S304 and always carrying a 35mm rangefinder (still hard to give up the M3)as a backup. I always carried extra batteries and would sometimes run out.

Since having the 20D I have not had to change batteries during the course of a day and no longer carry a film backup. I shot 300 to 400 pictures last weekend at at dog show on any of the days and did not need to change during the day. At the end of the day even though the battery indicator had not reached 50%, I would remove the battery for charge and replace with a fully charged spare.

Thanks for the replies, guys. In the month that I now have had my 20D, I have made only 2 battery changes. That includes well over 700 shots taken in a variety of situations, including my in-law's huge 60th wedding anniversary party where I used flash for approximately 100 photos of family members and friends. Given Canon's statement that the 20D's battery needs a couple of recharges to reach it's maximum efficiency, I'm more than happy with the "life" I'm getting from it.
