Keep shooting when the weather turns. This waterproof rain cover protects your camera body and lens together in one piece — no separate parts, no join for water to find — while leaving you full access to your controls. Size 3 fits the 100-400/100-500 class: Canon RF 100-500, Canon EF 100-400, Sigma 50-500 and similar — with or without a teleconverter fitted.
Why photographers choose it
One piece, no gaps. Camera and lens covered together — the body/lens join is where separate covers leak, so this design doesn't have one.
Shoot straight through the rain. Full operation with the cover on, so a downpour doesn't end the session.
Stays on the tripod. A dedicated opening for the tripod mount — no choosing between rain protection and support.
Teleconverter-friendly. Sized to fit with or without a converter mounted.
Field-tested. Used worldwide and proven by professionals. Made in the UK by Outdoor Photography Gear.

Waterproof Camera & Lens Cover — Size 3 (Canon RF 100-500, EF 100-400)
Returning customer of many years
— Phill DixonI have used the lens covers in multiple countries on large lens and always worked and kept kit safe from abrasion as well as improving comfort when using in cold climates. Have used this kit multiple times in Ladakh at 4000m down to -20 degrees without issue
I have previously bought three items
— Andy BakerNeoprene covers for a Sigma 150-600 and a Fuji X 150-600 along with a bean bag. I have been pleasantly surprised at the quality of each item, especially considering the competitive prices, and each item has stood up well to regular use.
Brilliant!
— Nick Wilcox-BrownI have many of these covers and they protect lenses beautifully. OPG always goes the extra mile to ensure that everything fits and delivery is fast. IMO these are the best covers you can buy
really impressed with the quality of the hide
— Ryan Lythlast week I purchased a lightweight bag hide and have been really impressed with the quality of the hide. it also comes with a good size bag to back it away and it does a great job breaking up your shape whilst providing excellent vision. I would definitely recommend for someone looking for a lightweight bag hide.
