I saw one with a larger zoom lens, and it was also 18 mega pixels, it was around $1100.00, I def want a better one, as I love photography sooo much.
Kind of off the main subject but....more MegaPixels, is not always better.
Canon has been cramming more and more mega pixels onto their APS-C sized image sensors because they know many dSLR buyers are motivated by the "more is better" line of thought.
Canon APS-C image sensors are a little smaller (22.3 mm x 14.8 mm), physically, than other APS-C image sensors (23.6 mm x 15.8 mm).
When more pixels are put onto a limited size space, each pixel is going to be a somewhat smaller.
Smaller pixels are like smaller buckets, and cannot hold as much as larger pixels can.
In the case of pixels we want them to hold light, which is made of little particles called photons. The more photons each pixel can hold, the higher the potential quality of the final image, which is why full frame image sensors (36.0 mm x 24.0 mm) are put in most pro level cameras, bigger individual pixels.
There is another important consideration regarding pixel size, and that consideration is image noise.
All image sensors generate image noise. It is unavoidable. But it can be limited and controlled if we have a signal that is significantly larger than the noise. That paramater is the
Signal-to-
Noise
Ratio,
SNR.
Here is a side-by-side comparison of 2 dSLR cameras that are at the same level in their makers line up and are direct competitors for the buyers dollars.
One has 18 MP, and the other has 12 MP.
The "more is better" school of thought would expect the 18 MP camera to easily outperform the 12 MP camera across the board, since it has 33% more pixels. The opposite is the real outcome with the 12 MP image sensor having
much better overall performance than the 18 MP camera particularly when it comes to actual ISO performance, Dynamic Range, Color Sensitivity, Tonal Range and
SNR performance. (ISO Latitude is an advertised value, not a measured value like ISO Performance.)

So a real life example that more is not always better.
If I were to make an image of the same exact scene with each of those cameras, would you be able to see the differences? I doubt it. Would I? Maybe. :blushing:
