Not every wants or needs a full frame camera.
Really?? that's your thinking? ok i'll take the shittier APS-C camera for $1200.00 even tho i could have a much better full frame camera..
Yeah ok.. Ok, so lets say some one who is in the market for a canon Camera but doesn't want full frame.
Ok so you buy the 70D for half the price and your getting basically the same camera the only difference is the 80D has 4 more Megapixels and better AF performance, oh goody ....
Maybe at the time some one might not want the full frame camera but if he / she really gets into photography and enjoys it and wants to take it a step further they would need to upgrade to a full frame sensor, which again is going to cost money, Why not pay the $1200.00 and get a full frame sensor even tho your not going to take advantage if it right away you will want to later on.
It's not a smart way to spend your money buying the Canon 80D, when you can get a full frame sensor Camera, period.
first off 4 more megapixels is not going to justify paying $600.00 more for the camera for 4 more megapixels is not going to be that much of a difference.
Many People believe image quality is all about megapixels but that is not true, at all....
You shouldn’t ignore megapixel counts entirely, Many people confuse high megapixel counts with indicators of how good a camera’s image quality will be, but in reality it’s simply a measure of how large you can view, resize, or print an image without seeing a noticeable decrease in resolution. Megapixels translate to image size, not image quality..
The sensor in a DLSR is the equivalent of what used to be film in a 35mm camera. The senor is exposed to the available light when you click your shutter speed.
It and other components capture and store this data. Because it's the sensor that's capturing and storing your images, this is the most important spec you'll want to consider.
The Nikon D610 is the larger full frame sensor, the Canon 80D is the smaller cropped sensor. which means the Nikon D610 will always produce better image quality then the Canon 80D
While smaller sensors struggle with capturing enough light, larger sensors are able to accommodate lower light situations.
Another advantage is having better control of depth of field.
With a larger sensor, you can more readily render an out-of-focus background behind your subject. APS-C sensors, however,
have one common disadvantage, and that's crop factor. Crop factor refers to how a lens is magnified when attached to APS-C-based cameras.
For example, if you use a 28mm lens, it would be magnified to look like a 45mm lens. In other words,
subjects are zoomed in a little bit more. While this isn't such a big deal, you should be aware of it,
especially if you're a landscape photographer who takes a lot of wide images.
While a good 28mm lens would look wide enough on a 35mm film or full frame camera,
it might be insufficient on a DSLR with an APS-C sensor.
where the Nikon D610 is the same exact megapixels as the Canon 80D, the Nikon will still produce higher quality images, because the sensor is almost twice the size.
But not quite
