I don't know anything about photography. I bought a Canon 60D two days ago with a lens 17-85. Excuse me, is this configuration good?

17-85 is a near-focus lens, which is enough for ordinary portraits and foreground. If the minimum focal length has reached 17, a certain wide angle has been shot, which is also enough for outdoor scenery and can reflect the depth of field effect. I suggest you match a medium telephoto lens: 70-200, 70-300, 50-500, etc. Canon original factory, Sima and Longteng can be used, you can refer to it. Don't forget to buy a UV mirror with high transmittance.
