I am a Canon Girl. But just so you know, DSLR cameras, in general, are simply amazing tools. Taking an awesome photograph is not about the brand of camera you use; it's about knowing how a camera captures light to create a photograph. It's knowing how to compose an image, it's how to bring out natural true emotion and expressions, it's about well-groomed post-processing techniques that are unique to the photographer. An artist can create amazing images with any gear, however, utilizing the right tools can greatly improve and excel the artist to the next level.
What's in a photographer's bag really depends on his or her own photography needs, style and skill level. So below is just a few things currently in my creative bag. Somethings listed are not shown (I forgot to throw them in the picture). But this is mainly what I do carry with me everywhere. It suits my current needs and my style. And while I love a great purposeful telephoto lens, I am completely in awe of my two main prime lenses.
