Canon DSLR help needed?

I currently have the Olympus SP-600UZ 12 MP but it is just isn't a good camera in my opinion, kind of cheap and not good quality. I'm currently saving money for a Canon Rebel EOS T3 that is 12.2 MP but i'm worried that it will still be the same quality. I'm wondering if Olympus 12 megapixels is the same as canon's 12 megapixel or if canon's may be better because it is higher quality camera. Please help out and give whatever advice you can to me on cameras or if there's a better camera from another brand like Nikon or something. I'm wanting to use it for travel, landscapes and such and of course on friends.

Image quality has nothing to do with megapixels & all to do with sensor size.

The sensor on the DSLR is far larger than the sensor on a point & shoot & it's this that will make a difference.

Also the optical quality of interchangeable lenses on a DSLR, designed for a specific purpose, will far outweigh the 'one size fits all' lens of a compact camera.

Actually there's a lot more too it than just sensor size. Yes that plays a major role in quality but the quality of the lenses you use plays a large part in quality as does data handling inside the camera once a photo has been taken.

Then there's the matter of photographer skill. Since you have a dslr already you're most likely familiar enough with it to stay off of full auto, do some settings that will help you make better photos and understand the relationship between ISO, aperture, shutter speed and light.

There's lots to quality photos. I own and only recommend Canon products because i know their attention to detail and quality.

The T3 will be a lot better than the SP-600 which doesn't rate too highly in reviews.

The one thing that you will need to be aware of is that the Olympus has a 15x zoom, something that you will not get with a DSLR. Typically the zoom on a camera like the Olympus starts at a focal length of around 24mm and goes to 15x that (360mm). If you get the Canon you'll probably get it with a 18-55mm zoom lens (just over 3x as a lens zoom ratio) and then you'll need to get other lenses for shorter or longer focal lengths, and that's where life can be expensive with DSLRs.

The 18-55mm should be fine for most landscapes and people shots.

If you are on a budget, you won't gain a whole lot going with Nikon, Pentax or Sony, the other main DSLR manufacturers, all of which produce cameras of fairly similar quality and performance at the consumer end of the market. There are minor differences between them and Nikons are typically better in low light - less noisy images at higher ISO - but for most scenarios there's not a lot to choose between them.
