How can I protect my Canon EF 50mm f/1.8 STM lens from rain

1. Use a UV Filter: Attaching a UV filter can provide an additional layer of protection for the front element of the lens. It helps to prevent moisture from entering and also protects against scratches and dust[9][10].

2. Lens Hood: Utilizing a lens hood, such as the Canon ES-68, can help shield the lens from rain and minimize the chance of water droplets hitting the lens surface[5].

3. Rain Cover: Invest in a rain cover specifically designed for cameras and lenses. These covers can protect your gear during light rain without hindering your ability to shoot[9].

4. Keep It Covered: When not in use, keep the lens covered with a lens cap or a protective bag. If you need to shoot in the rain, consider using a plastic bag or a dedicated camera rain cover that allows for quick access[9].

5. Wipe Off Water Immediately: If the lens does get wet, use a dry microfiber cloth to wipe off any moisture as soon as possible to prevent water damage[9].

6. Avoid Prolonged Exposure: Limit the time your lens is exposed to rain. If possible, keep it under your jacket or a cover until you're ready to take a shot.

By implementing these protective measures, you can help ensure that your Canon EF 50mm f/1.8 STM lens remains in good condition even in rainy conditions.
