Plastic Wrap Can Be Used as a Pellicle Mirror Substitute
After damaging the pellicle mirror in his Sony A55 with cleaning fluid, a guy named Dario decided to look for a makeshift replacement while waiting for a real replacement mirror to arrive. He then discovered that food wrap (AKA Saran wrap) works nearly as well as a real pellicle mirror. The only downsides are occasionally degraded autofocus and a soft-focus effect when facing bright lights.
