I use a Canon 6D DSLR 20 megapixel camera. I love this camera because I am able to change the settings quickly, it has a low light setting or a high ISO number, it focuses well and I can use a variety of lenses with it. I have another Canon T5i camera but I use the 6D most of the time. A client told me they had attending a wedding where the photographer shot the wedding their cell phone! I would not recommend this because although cell phones take excellent photos you are not able to get the same range as a dslr camera does. Sure, a cell phone would work in an emergency but I would not shoot an entire wedding with a cell phone!
