Best Microphone Flags

Aperture diameter is the only spec that decides whether a mic flag fits, and it is quoted in a way that is easy to skim past. A 1.54 inch hole, about 39 mm, clears the barrel of a typical slim handheld interview mic and a reporter condenser, but it will not go over a fat-bodied broadcast dynamic or a mic already wearing a foam windscreen. Measure the barrel just below the grille before you order, and remember the flag has to slide past the capsule end, so the widest point of the head matters as much as the shaft. Face count is the next choice and it maps directly to how you shoot. A triangle gives you three printable faces and stays readable from a fairly narrow arc, which suits a fixed camera and a seated interview; a square or cube gives four faces and reads from any angle, which is what you want for run-and-gun press work where the mic rotates. Cubes are also bulkier and add more weight to a hand-held mic, and weight is the thing people underestimate on a long standup. ABS is the standard material and the useful distinction is not the plastic but the finish: a matte blank panel takes vinyl or a printed decal cleanly, while a glossy shell throws hot specular reflections back at your key light. Multi-packs of six or eight make sense only if you run several mics or expect to lose them on location.
