PowerShot / Re: New PowerShot Digital Compact Camera Under Development

Now add in my 'old' idea: give this boogar a rechargable lithium battery that is shaped like 4 AA batteries; the best of both worlds.

4 AAs produce 4.8V (rechargeable) or 6.0V (alkaline).  Lithium batteries produce 3.7V (1 cell) or 7.4V (2 cells).

How are you going to handle the different voltages and how are you going to estimate remaining capacity when you have different voltages and different discharge characteristics?

Well that's pretty easy.  You design it that way.  Take it for granted that 4 double a's are not going to last as long but how it gets done is easy, for Canon's engineers. 

Also to note a lithium the size of 4 AA's would be bigger and give it a higher capacity as well.  They could design the voltage of the Lithium battery to match that of 4 AA's and then it would be a natural.

Using 7.4 V Li Ion or AAs (4.8 V or 6 V) batteries and an internal voltage of 3 V - a step down converter circuitry can handle that with efficiencies of roughly 85 % . Or use a combined step DOWN / step UP converter with less efficiency.
The camera has to be informed by the battery (or menu) about the battery type to know it's discharge characteristics.

But - IMO - to expensive / complicated (choosing battery type in menu) for users who like the concept of a easy to use wide range zoom ...

Simple solution, the Lithium is a Canon battery.  Canon could easily put a chip in it like laser cartridges that tells the camera this is Canon Battery XYZ and the camera would know on start up.

to me it sounds like......SX1 MK2

They do say "premium", and the SX50 felt plastic-y compared to my SX1.

PowerShot Cameras / A very attractive Powershot idea: SX1 MK2
« on: December 15, 2013, 12:52:37 PM »
I have an SX1 and love it dearly.  Since it came out many other powershots have come out.  I keep waiting, and ::sigh:: what I'd love to see may never happen.  But, I think it is worth throwing out valid ideas, and here is a wish list for a SX1 Mk2.

1.  A larger CMOS sensor.  Not massive, but bigger.
2.  The 50 times lens from the SX50, but, bigger diameter, so faster
     (yes I know it means bigger and heavier, but if you had that 50x and one stop faster than the SX50 would you care?)
3.  A new battery idea.  Keep the proprietary battery, but shape it like 4 AA batteries.  Now you would be able to put in 4 AA's in a pinch, and still enjoy the power of lithium.
4.  HDR
5.  Yes, keep my precious remote, but make it just a little bigger, just a little.
6.  Keep the 1080p 30fps
7.  Give it real threads up front for filters instead of needing an adapter.
8.  Put a focusing ring on the lens for manual focusing.  It could also kick in manual focusing just by turning the ring.
9.  Spend a couple extra bux a camera on packaging that will protect the camera.  The paper mache was split on my SX1.

Well that is a sweet wish list.  But I'd like to say I'm still thanking Canon for my SX1.

tc,

Rich
