Good evening all! I am getting into some photography and I have a couple of questions. I understand some of the concepts but not all. The camera I have is a 30D to learn in and plan on grabbing a newer one after snagging a few lenses. My lens starting point is EF 85mm 1.8, EFS 18-55mm, and EF 75-300mm. 1. As far as prime lenses go, would it be beneficial to get a 24mm 2.8, and a 50mm 1.8? I love the 85mm but it's a tad long for indoor use. Can the 24mm take good group photos in doors? Is there a downside to haveing both? Is there a better option? 2. I understand that the mm on the lens is multiplied by 1.6 to get the full frame equilavent. From what I have read, a good macro lens in a 100mm canon (i forget the rest of the info). My assumption is that this is great for FF and shooting insects and such. My question is this, would a 60mm macro lens accomplish the same on a crop sensor since that equates to a 96mm lens in FF? Can you keep more distance between you and your subject? Thanks for reading and double thanks for a response!
