Yes. This is a useful, common problem, and there are purpose-made rain covers for cameras and lenses. Many are essentially lightweight protective sleeves, so a DIY version can work too if you want something cheap and packable. Community suggestions included making a cover from waterproof clothing material or even using a small plastic bag/shower-cap style cover with a hole for the lens.

For the front element, a lens hood is one of the simplest and most effective tools. It helps block falling rain and snow from landing directly on the glass or filter. Keep a couple of dry cloths handy to wipe off drips as needed.

Snow is usually less of a problem than rain unless it is wet and melting, since dry snow can often be brushed off before it turns to water.

So the practical approach is: use a rain cover or simple plastic DIY cover for the camera body, use a lens hood on the lens, and keep dry cloths with you. That setup gives you much more freedom to shoot in bad weather while reducing the risk to your gear.
