Nikon,d300-d3-and coolpix s700. all are near 12 million pix. what is the diffrence in three types?

Question

Because d3 is very expences then coolpix. is sure all cameras give same result by due to same high mp.

Answer 1

depends on optics and sensor size and type, DSLRs have generally much better optics and larger sensors

Answer 2

You're wrong, just because they have the same amount of pixels, doesn't mean you're going to have the same quality.

IN simpler terms, you pay 5,000$ for the d3 for a reason, it's

a professional camera, and it's not going to be rivaled by a

point and shoot camera ( at least not in this generation )

coolpix cameras are very "cheap" in the camera world. The

nikon d3, and d300 are thousands of dollars, and trust me, you're not going to get the same results. Pro. Cameras are

Pro. cameras for a reason, they are used professionally,

and those coolpix cameras are made for day-to-day

use

Answer 3

1) the cameras do not give the same result.

2) megapixel numbers do not tell you the real story.

3) the difference is actual the physical size of the sensor

4) the D3 has the biggest chip, followed by the D300 and then the S700, which has a tiny sensor chip.

5) Because the S700 has a tiny chip, it's a sensor that makes noisier images, with poorer performance in low light.  Moreover, you don't get access to specialized lenses.

6)  the D3 has the largest sensor, which means the best performance in low light, clean noise-free images, and better dynamic range (brightness to darkness values in image).  The D300 is good too, due to its sensor size, which is large, but not as big as the D3.

7)  On the D3 and D300, you can change lenses.  That's a big deal, allowing you to choose the best lens to match the situation.

So, the cameras do not give the same result and you should not evaluate them by the megapixel number alone.
