The poorer battery life of the SX1 compared to the SX10 may have various reasons – except for the CMOS sensor which consumes less power as CCD sensor.

Hello! How come there are no substantial rumors about new Canon EOS DSLR’s in January. Did Canon lock down all their staff behind sealed doors completely, or is there no new cameras coming this year at all?

CMOS vs CCD power consumption: Canon SX1 IS (Cmos) has significantly poorer battery life (CIPA) than SX10 IS (CCD).

CMOS power consumption: Do you have a reference that indicates CMOS cameras consume more power? Everything I can find indicates similar or lower overall power consumption. I do not believe that a claim of shorter battery life due to CMOS power consumption is correct.

From Dalsa: They say overall cmos power consumption is less.

From Canon:
The CMOS Difference
Canon CMOS sensor technology offers several advantages over traditional CCD sensors. Amplifiers at each pixel site vastly speed up the process of getting the signal to the image processor. Unnecessary charge transfers are avoided, lowering power consumption and prolonging battery life.

Will the SX1 IS be announced in North America at PMA? It has already been realeased in the UK and Japan.

@Ed: It’s not about the sensor, is the extra circuitry needed with CMOS what eats more power in general ;)

Where does the idea that CMOS takes more power come from? One of its stated advantages is that it uses less power. Does someone have different information?

The SX1 has a very long zoom lens with IS that probably really eats up power. It has a high powered flash as well.

The 150-200 photo life is for alkaline batteries, ni-mh are much better.

The new camera rumored here does not have a huge power hungry zoom, and has a li-on battery. I would expect longer battery life than the ccd equivalent.

I don’t think Canon will put the CMOS sensor on IXUS series. As we have seen the high power consumption in SX1, it’s doubtful to put CMOS sensor inside the ultra-compact camera. Users will be upset to know their new IXUS can only take 150 photos with a full-charged battery!!

When is the PMA?

Hej,
That early, prolly it won’t be better than the sensor from SX1, and considering the zoom, the sensor will be small too. I don’t understand why they would do that in early 2009.
