Megapixels are NOT everything. Despite point and shoot cameras now coming with up to 12 megapixels their quality level is not necessarily has good as a DSLR with only 8.
The image sensor used in point and shoot digital cameras is generally much smaller than the image sensor used in a DSLR, This means that the pixels on a point and shoot camera have to be much smaller and collect fewer photons. The long and short of it is that because of this point and shoot cameras need to work at slower ISO levels which means that they produce “noisier” (or more grainy) shots. There are smart phones that are getting better and better at taking digital images. Someday the iphone technology will take photos just as good as a DSLR, however, the large lens used in DSLR will always be able to get better low light and detailed quality shots than a smart phone unless they can figure out that technology but not anytime soon, well at least in the next 10 years.
Should You Buy a DSLR or a Point and Shoot Digital Camera?
It depends on your budget but in the long run, it’s worth getting a DSLR with a professional lens to post those images on your website or something that you plan on showcasing.
If you’re only taking simple website or group images at a party, your smart phone is good enough and we’ll get to a point in the future where you won’t need a DSLR anymore
but the technology is not there yet for what the DSLR can do at its price point.
