Hello everyone. I've just decided to buy a DSLR camera. However i'm not sure which one is best choice. First of all i've heard that recording video for a long time with dslr cameras harmful to sensor , because of that i'm looking for one without recording feature. I compared 500D and 450D and there is some differences such as ISO values. 500D between 100-3200 but 450D between 100-1600 Now i wonder that is this a crucial difference ? Also what are other features i have to consider while making comparison ?
