>>2962904Because the most expensive equipment is harder wearing, has better autofocus, better customer support, better battery life, better rear screen, better viewfinder. None of these things have any bearing on the images actually coming out of the camera.
As far as actual hardware and image quality, it's the same sensor in the pentax k30, sony nex c3, pentax k5ii, fuji xe1, fuji xt1, fuji xpro1, nikon d7000 and this list goes on. Each of these will give very comparable image quality, despite ranging in price from a couple of hundred to a couple of thousand. In reality there are only 5 or different sensors on the market at the moment, and they're either made by Canon, or Sony (Canon is found in canon cameras, Sony is in everything else, Canon is about a decade behind)
Pro's have better photos because
1. They know what they're doing, a camera is a tool, just like a guitar or chisel, no-one just picks it up and plays a song or carves a statue, it takes years of practice.
2. This extends to software, post processing is a massive part and a massive learning curve
3. They take a lot of photos
4. They have good lenses, if you want lots of smooth bokeh you need fast, expensive lenses.
There is one factor that will effect your image quality, and that's if you decide to go "crop" or "full frame", go do some google if you're not familiar. Full frame will give sharper, cleaner images, with more, better quality bokeh. At the expense of being more expensive, and needing larger, more expensive lenses.
