The reason that your shots won't look like that is, because (and it gets pretty technical), but the simple and uncomplicated answer is. A point-n-shoot is not a DSLR. A DSLR camera gets great shots, because it has a completely different sensor in it. in the Canons they use what is called a CMOS sensor, basically it is what transfers the image you see to the Digital Memory card. Short story long... The p-N-s doesn't have as sensitive a sensor, nor does it have the Single Lens Reflex.....IE (Mirror) that you see when you take the lens of a DSLR off. This mirror is what gives the camera such a good picture, along with the sensor to record it of course. You could buy a 15 MP p-N-s and a 15 MP DSLR and the DSLR is going to win the photo contest hands down everytime, due to picture clarity and quality.
It is a Gynormous lens... It also cost a Gynormous price, lol! Nah, I borrowed it from a good buddy of mine. He happens to be our wedding photographer and that is what he does for a living....so it helps! But, that lens costs about $2,000. It is all in perspective though. $2,000 doesn't really seem like much when you consider just the body alone of his camera is almost $8,000!
Canon Mark IID = 37 MP and a price tag between $6,000 and $8,000 Just for the body!
