Hi fellow Shutterbugs. I'll be leaving for a trip to WDW next week, and I'm thinking about renting a lens for the trip. I shoot a Sony A700 with a Sigma 18-250 f3.5-6 as my walkaround. I also have a 50mm f1.8 prime that I'm planning on taking. I really want to get good indoor shots, especially at Enchanted Tales with Belle. Should I rent a 30mm f1.4 or a 17-50mm f2.8 to enhance my indoor shots? Should I stick with the 50mm for shots as needed? I would definitely like to reduce reliance on flash for the trip. Thanks for your thoughts.
