What relationship does megapixel rating have with image quality?

highest megapixel camera cheap image

Hi,
I am about to purchase my first DSLR, and I am noticing that nikon has a 24 megapixel (D3200) for 550 dollars at my best buy. Their better and more expensive model, however, only has a 16 megapixel rating (D5100.) Cannon also has options... with a slightly higher megapixel rating and a slightly better camera as you go down the line. How worried should I be about megapixel rating? I won't really ever be printing over 11x14's.
With a higher Megapixel rating, Will that provide the ability to print a larger image without seeing the fuzzy dots that make up the digital image? Does image quality in a more expensive camera sometimes trump a large megapixel number in a cheaper camera?
Thanks a heap.

Answer
megapixels are not a measure of image quality.

the marketing teams of camera companies push the numbers higher and higher only to sell cameras.

Don't fall for the large print myth. People here give advice as if everyone were going to print up big billboard photos.

12-16MP is enough for anybody not making money selling large gallery prints.

When you add pixels, you must pay a price, there is no free lunch. The 3200, 5200 and 7100 take a hit in low light at high ISO vs a lower pixel count sensor. So you have to weigh the feature set of each camera, along with the image sensor.

Lastly, don't fall for anyone posting links to DxOmark.com. Those up front numbers don't tell the truth, you have to dig into the data to get the real performance of the image sensor. The D3200 sensor, when you see the real numbers, is no better than the old D3000.

The real champs when it comes to APS-C image sensors, when you see the real data are the Fuji X100 and the Pentax K5 II.

Shoot in RAW format, keep your ISO low, and with 16 MP, you can go really big if you need to.

What is a good amount of megapixel's for a digital camera?




Oh my.


I have never bought one before. Im looking for one to be used to take everyday kinds of pics. I dont need one for professional photographs. Expensive, as I see ones with higher megapixel's. I dont want a cheap one either. What's a good range to buy in?


Answer
The amount of Megapixels you require all depends on how large you think you're going to eventually PRINT the images.

If you think you're going to print your photos to suit a 6 x 4 inch frame or 8 x 10, then a 5 megapixel camera would suffice.

But just letting you know that megapixels alone doesn't determine how good a camera is, it's more to do with the lens and how good the sensor is. Look for a sensor that is less noisy in dark conditions and you should be right.

Good luck!
