Phil's G3 mistake !

Marios Athineos said:

first of all let me paste what Phil says about his test:

"We ran the camera through our new battery life test. This test is
designed to be fair and comparative to each camera and battery type:

Take 4 shots without flash
Wait 2 minutes (50% of the time powering the camera off)
Take 1 shot with flash
Wait 1 minute
Repeat"

I think the test favours EVF cams.

Why. Well look at imaging-resource cam reviews where the current
consumption figures are quoted.

Capture modes w/o LCD (or with EVF) are lower (as in significantly
lower 20 to 80mA vs. 300 to 600mA) for non-EVF vs. EVF cams.

With shutter button pressed the figures are closer. (non-EVF cam
is doing similar work to EVF cam at that stage).

Phil's test doesn't reflect this. It doesn't make the test invalid.

The significant factors for the non-EVF cam will be the length
of time the shutter button is half-depressed during the test.

The other factor is the use of the LCD. No comment is made on
how many shots are taken using the LCD. Each shot taken using
the LCD will converge the results.

Do you mean OVF cameras? I would think that because Phil test doesn't use the LCD, the EVF would drain the batteries more quickly than an OVF (or is there something I'm missing?)

I don't think that Phil uses the LCD in his battery life tests, and I agree that the two battery lives will come closer if both cameras solely used the LCD for framing shots.

Some thing even more interesting from the same table is that:

S45 190
S40 225

so in this case the new DIGIC processor actually made things worse ?
kinda weird don't you think ?

Hi guys,
I just wanted to point out something that might have escaped your
attention (probably Phil's mistake). In Phil's latest review of
Minolta DiMAGE 7Hi he actually posts the battery life data of G3
and it turns out that ...

IT EVEN BEATS ALL THE SONYs ! ! !

Go on page "9. Timings & Sizes"
http://www.dpreview.com/reviews/minoltadimage7hi/page9.asp

I copied the last 4 lines of the table and take a look at the last
line:

Sony DSC-S85 NP-FM50 8.6 Wh 3 hr 50 mins 400
Sony DSC-F717 NP-FM50 8.6 Wh 4 hr 02 mins 405
Sony DSC-F707 NP-FM50 8.6 Wh 4 hr 20 mins 440
Canon PowerShot G3 BP-511 8.1 Wh 4 hr 32 mins 455

WOW ! ! !

ps
this means that the full review is only days away ...
