Sony offers several lenses with excellent weather sealing, particularly in their G Master and G series lineups. While no lens is completely weatherproof, these lenses are designed to withstand challenging conditions. Here are some specific models to consider:

1. Sony FE 24-70mm f/2.8 GM ($1,998): This versatile zoom lens features a durable construction with extensive weather sealing, making it a great choice for outdoor photography.

2. Sony FE 70-200mm f/2.8 GM OSS ($2,598): Another G Master lens, this telephoto zoom is built to handle tough weather conditions, with sealing at critical points to prevent dust and moisture intrusion.

3. Sony FE 16-35mm f/2.8 GM ($2,198): For wide-angle shots, this G Master lens offers excellent weather resistance, allowing you to shoot confidently in rain or snow.

4. Sony FE 90mm f/2.8 Macro G OSS ($1,098): If you're interested in macro photography, this G series lens provides reliable weather sealing for outdoor close-up shots.

In my experience, I've used the Sony FE 24-70mm f/2.8 GM and FE 70-200mm f/2.8 GM OSS in various weather conditions, including heavy rain and dusty environments. Both lenses performed exceptionally well, with no noticeable impact on image quality or functionality.

However, it's important to note that weather sealing is not foolproof. Always use a lens hood and avoid changing lenses in harsh conditions to minimize the risk of moisture or debris entering the camera body. After shooting, be sure to clean your gear thoroughly and let it dry completely before storing.

Overall, investing in weather-sealed Sony lenses from the G Master and G series is a smart choice for photographers who frequently work in challenging environments. While they come at a premium price, the added protection and peace of mind are well worth it.

Most GM lenses are weather sealed.
