What is a good time to upgrade your digital camera? Unlike computers, there is no XP that drives you to upgrade your humble 486. While there is no point going to a 7 megapixel from a 6 megapixel (make sure you get at least twice .. if not 50% more to make different) , there are other reasons., newer digicams (esp. SLRs) have made huge improvements in shutter lag compared to top end models from two years ago.
1. As stated above, it's not always about megapixels. An upgrade can be warranted by needed features. In my case I upgraded from my Minolta Dimage 500 (5MP) to the Canon SD500 (7MP) for the faster startup and continuous shooting modes, as well as better video quality and smaller size.
CCD quality is an issue as well. My friend's 4MP Canon had crisper images than my 5MP Minolta.
I believe an upgrade is needed as soon as your current setup no longer meets your needs and you can affordably purchase a new camera.
When it comes to DSLR's keep in mind what you already have. Will the lenses and filters be compatable? Can you use the same battery packs? Interface cables and media? A body upgrade can mean a world of difference and cost if you can reuse old equipment.
