Canon IXY 810IS Digital Camera

My not so long ago purchased camera was broken and I bought a new one on 8 October 2007. Well, it's a mixed feeling not sure if I can describe it clearly because I am still not sure what it is even now. First, the old point-and-shoot camera had a little defect on the LCD screen. There is a quite noticeable crescent shaped mark on the LCD screen, you can't miss that defect and there is no light from behind that mark. Plus, the model is a little old then, however the camera still works without a flaw in terms of creating flawlessly beautiful photo (the defect is only on the LCD screen, but not in the digital photos produced). So far, it is still OK for me to use that camera. However, one day suddenly my lens camera stopped coming outside, i.e. it is stuck, cannot pop out, with an error code. I looked it up on the Internet how to fix it, but although I followed the instructions, which are quite brutal instructions actually, by making the lens come out and goes in with force, it made the camera to become worse. I was very worried even to hand it to the camera repairer (Anderson camera repairer in Capalaba), because I believe the camera is beyond repairs, I may have damaged the lens also, which is, I think, worth most of the camera value.
So, during this vulnerable and confused moments, I ordered another camera from a Chinese seller in Japan, in eBay. The product has ok price, about AUD$370 including shipping, which another person might find this is a small price compared to the shops here in Brisbane, RRP AUD$499-AUD$549. This camera is with Canon Japan Manufacturer warranty, so if it breaks, I will need to send it back to Japan or I can repair it by the repairer in Brisbane paying out of my own pocket, whichever is cheaper.
Here is another, somewhat disappointed and confused moment. I felt that the Canon IXY 810IS is inferior to the IXY 700, in that the picture 810IS is grainier than IXY 700. This could be caused by possible numerous cause. The lowest ISO setting is now 80, instead of 50 in IXY 700. There are many more automated features in 810IS that would compromise/cause the lower quality 810IS, including the face detection, smaller build which means the sensors packed is smaller too and the Image Stabilization feature would probably cause the grainier pictures too. It could also be caused by the contrast setting that results brighter grainy dark places.
But whatever the cause of this is, I am pretty sure I don't have the ability to make this camera perform any better. If caused by hardware I am hopeless, if caused by software I am pretty much hopeless too. All I can do is download the software from the Internet and update, because I don't have the facilities to build the software (or hardware) from scratch, let alone to come with another solution (it would be quite impossible, otherwise I might just build my own company making better cameras than Canon and be a millionaire, hehe).
At points in time, I found also, that I wouldn't want to go back to use my old IXY 700 because of the defect and plastic protected LCD screen. My new camera has a glass protected LCD screen which is much more protective to the behind screen.
In brief moments, I thought also the quality of the picture is almost the same.
Depending on lighting conditions. I found that too much sunlight would result the dark places look darker and therefore grainier, as my friend Steven Wong would probably refer it to me.
Plus, I saw the old photos of IXY 700 again, and they do have grainy dark places too! Now I don't really know anymore. Is this camera better, or worse?
One thing for sure, the video recording of IXY810IS is better, because it has larger area (640x480), has Image Stabilization and Face detection. Why haven't I been happy I wonder? Is it the shock or... my lack of money for spending for a product that I already have... I am not sure and probably both, and probably not too. What a confusing time.
Anyways, this camera works superbly for my selling in eBay, in fact, too good for the photos of the products I sell. I definitely need this camera for selling on eBay. I need excellent quality. This is the only thing that I do most of these days. And I need a camera anyway.
Amongst this totally confusing and a possibly (because I don't really know even now) disappointing time, I hope I can find this camera useful.
I hope I can find the courage one day to go to Anderson Camera Repairer and fix my IXY 700, because I am pretty sure that it costs about the same as buying a new IXY 810IS. How sad.
