    I am confused and obviously not an expert on photography! I have been told that the sensor size is extremely important and that if the sensor size is small, such as in lower priced p and s cameras, there will be poor quality the more the MP size because of noise. So, what IS a good rule of thumb? I have looked at SLR cameras and they may have 14 or 16 MP and not very large sensors themselves, unless we go up to the $1K or more range.

    I'd like more zoom, but it seems that in every p and s I find, more zoom seems to go with higher MP and that small sensor once again!

    your budget may decide - as soon as you get into DSLR - you are then looking at lenses etc

    DSLR - mainly have two types of sensors - APS-C size or Full Frame - full frame referres to the sensor being the same size as 35mm film

    this may help

    You consider 14-16 MP "not very large"?????

    What size prints do you contemplate making?

    (EDIT: I have a Canon 30D -- 8.2 MP -- and that's big enough to make very nice 11x17 prints.)

    jethsy,
    sometimes just a little info is enough to really confuse an issue
    i would have to say that pretty much any camera on the market is a good one - FOR THE PURPOSE IT WAS INTENDED FOR!!! :)
    the problem arises when we try to use one thing to do something else with it :eek:
    many of us who are very serious about our "hobbies" can get a considerable amount of $$$$ invested,
    thus when someone asks a question about something SIMPLE - the answers they get are totally skewed by those who are much more involved in that "hobby"
    but the basic questions are still the basic questions - the first, and the most important being:
    WHAT ARE YOU GOING TO BE USING IT FOR???

    so...
    to get an answer to your what seems a simple question, you will have to delve a bit into what some of the constraints are upon the manufacurer - $$$ vs $$$ yielding PROFIT :D

    maybe this for a start so that everyone is on the same page about the terminologies of the technologies used:
    http://photo.net/equipment/digital/basics/
    Digital Cameras - A beginner's guide

    then to this:
    http://photo.net/equipment/digital/sensorsize/

    then to move on to how inter-related ALL the things a manufacurer must consider and deal with when designing a camera:
    good tutorial on sensor size with considerations for other influences:
    http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm

    the info in this article is quite dated about the models mentioned,
    BUT
    gives a person an idea of the many factors needed to be thought of when getting ready to buy a camera, even if it is just a p&s unit:
    http://photo.net/equipment/best-digital-camera/

    this site gives some good basic comparisons from the simplest p&s to the better dslr models:

    these articles from wikipedia are good for someone wanting to know more on the subject without getting burried by a bunch of big technical words you would have to go to college to learn what they mean:
    http://en.wikipedia.org/wiki/Image_sensor_format
