Haven’t decided if the extra $100 would be well spent on the 12.1mp versus 8mp, especially with these point and shoot, I suspect there’s a limit how effective a higher res camera would be beyond 6mp.
As you go to a higher resolution on same size sensor chip, you run into ISO noise issues. You are trying to capture light with a smaller cell within the chip. To do this, the gain on the op-amps has to be pushed up. Any noise or even quantization noise gets magnified. DPreview shows both the resolution and sensor size. They also run noise analysis.
One thing I did notice is that the SD950IS(12Mpixel) has a larger sensor (1/1.7″) vs the SD850IS(1/2.5″)(8Mpixel). This would mean that the SD950IS will do as well or better in low light and the flash response would be better (would not need as bright a flash).
SD850IS photo sensor cell is 2.2um across
SD950IS photo sensor cell is 2.2um acrossIf you are shooting 4×6, anything over about 4Mpixel doesn’t add anything. If you want to print an 8×10, larger resolution does matter. I have a 12Mpixel DSLR and a friend of mine has a 6Mpixel DSLR. The difference is quite noticeable. on 8x10s.
I’m sort of bummed that it’s getting harder to find simple point and shoot that take the compact flash format. I hate memory sticks and SD cards are yet another format I need to stock now.
I agree here.. for the heck of it, I checked if my old point and shoot was still available.. it is and they are asking insane prices for it now, much more than what I paid. It does take CF (as do my other digitals).

February 24, 2008 at 7:41 PM #159185CoronitaParticipantAgain folks, thanks for more input. I hate shopping for electronics, because the moment you buy it, it depreciates by 50% the next day. But I guess I can think of it as a freebie.
ucodegen,
thanks for the input. I didn't realize the sd950is has a larger sensor. I thought both had the same size sensor, which to me made think the higher res a moot point. But now that you point out sensor size is different, now I'm leaning there. For point and shoot, we rarely do anything larger than 5×7. But I guess since this is a free gift card, I might as well use it up. We've use to use a Digital S110, which is a 2.1 mp camera. Gave my sis a S300(or something like that) and my dad an S400(or something like that). Everyone's been pretty happy. I thought there might be something other interesting from another brand. Sony was interesting, but again I have issues with memory sticks…. I guess I'll continue the tradition with canon.
For quality shots of my daughter, I still plan on using my Digital Rebel XT with my Tamron 17-50/2.8. Yes, I'm no pro, and couldn't justify buying a full frame Canon DSLR with a Canon L series lense. I've been pretty happy with it, except the lense won't be transferable to a full frame camera if I ever want to go there. Plus it was also free from another gift card and with Best Buy making a $100 pricing mistake on the body.
Guess I need to buy another memory card too. Grrrrr

March 3, 2008 at 8:03 PM #163676CoronitaParticipantWell, my Canon SD950IS arrived today. All I can say is wow. Image Stabilization is awesome. The sad part is that I think my pictures taken with this camera are coming out better than the ones I shoot with my digital SLR, which was considerably more expensive (tells you what my skills are like).
Anyway, thanks all for the recommendation. I haven’t bought a electronic toy that wasn’t work related in over 2.5 years. So I’m a little giddy right now. (Ah yes, it’s the little things in life that make things interesting).
