Of course a DSLR has a huge optics compared to any phones and also the price range is starting at the price of a phone.

...and also a DSLR usually produces pretty good photos but only if the photographer knows how to use it. If not, the photos may be only a bit better than a photo of a good phone camera.

I remember few weeks ago I saw a photo what a journalist took about one of our products at an exhibition. My colleague also took a photo of the same thing which was better than the other... then I looked at exif info of the journalist's photo and astonished how was able to take such poor photo with that machine...
