I got this one! From the Miller Park A-to-Z Guide: Cameras & Video Equipment Guests are permitted to bring cameras and video equipment into Miller Park, provided that they are intended for personal use only. Videotaping of any field activity, Brewers staff, or its agents is strictly prohibited. Guests are not permitted to stand in the aisles, wells or walkways, or obstruct others from viewing the game while taking photographs. Monopods and tripods are not permitted. Persons deemed to be violating these rules may be ejected, and the footage may be confiscated. Carry-in Policy Guests may not bring any cans, glass containers or alcohol into Miller Park. Soda, water or juice must be contained in factory-sealed plastic bottles. Guests may bring food items into Miller Park using appropriate containers. All bags, purses, fanny packs or soft-sided coolers must be 16" x 16" x 8" or smaller and are subject to inspection. Hard-sided coolers are not allowed in the ballpark. Only food purchased within Miller Park will be allowed into Suite areas. -- I've never tried to take a camera bag into the park, since it's not the greatest environment to switch lenses. I regularly take a DSLR into the park, with a hefty 200mm lens on the thing, and security never gives me a hard time about it.
