I bought this camera new and since then I have been full of happiness with the video and the quality this beautiful camera give me. However lately I have notes that the HD quality is no there any more. More and more I see my images lacking of that great sharpens use to have. am I doing something wrong? is there something in the menu I some how selected and not look like this. or is just normal sensor degradation?
I have read about this things last forever but I don't know what can cause this. this is some video shoot under the same conditions on March of this year and July http://www.youtube.com/watch?v=F_XMGU8Inxc
Now when I shoot I make sure is in focus. In the LCD looks great and sharp. but when I download it in the computer looks like this. any suggestions?
I found this opinion in other forum:
CMOS devices do have shelf life's.
But these devices tend to be tested so well that the user does not see failure before other parts in the camera go bad first.
Generaly - high end devices go for 2000 hr and 5000hr accelerated life test before they can be sold.
It is the cheaper products - think cell phone parts - that do not have the same life expectancy.
As long as the CMOS chips stays in the operating temp and does not get a voltage spike or physical damage - you should have no worries.
There are chips that will have 'hot pixels' show up in there life time. Then it becomes a software issue (option) to remove them while using the device or you throw the device away.
You will probably never see Sony (Nikon) or Canon talk about Life/Yield parameters. it is industry practice.
