Learn how to fit and use the LensCoat RainCap Large to keep rain, snow, sand, and dust off your long telephoto lens. Step-by-step setup tips and common mistakes.
Quick answer
Slide the LensCoat RainCap Large over the front of your lens, pull the adjustable bungee cord snug, and check that the taped seams sit flat before you head into rain, snow, or dust. It is a simple cover, but a few setup habits make the difference between real protection and a loose flap.
Why the RainCap is a front-element cover, not a full raincoat
The RainCap Large is designed to cover the front of your lens, not the entire barrel and camera body. That makes it fast to deploy when weather turns, but it also means you still need a plan for the rest of your gear if you expect sustained rain. Pair it with a RainCoat or similar body cover when conditions are truly wet, and use the RainCap alone for quick showers, blowing sand, or dusty sidelines where the front element is the main risk.
Fit check: when the Large size is the right call
LensCoat does not publish a specific lens diameter range for the RainCap Large in the supplied catalog, so fit depends on your lens hood and front barrel. As a practical rule, test the cap over the hood you actually shoot with. If the bungee cannot pull the material snug without gaps, or if the cap barely reaches past the hood rim, you are likely at the edge of the size. The RainCap is made to work with or without LensCoat covers and RainCoats, so you do not need to remove existing protection to use it.
Step-by-step RainCap setup
- Start with a clean, dry front element: Before covering the lens, use a blower and lens cloth to remove any dust or moisture. Then slide the RainCap over the front of the lens or hood. Common mistake: trapping grit under the cap can grind against the front element or filter. Clean first, then cover.
- Seat the cap past the hood rim: Pull the RainCap down until the elastic edge sits behind the widest part of the hood, not just balanced on the rim. The material should overlap the barrel slightly. Checkpoint: if the cap pops off when you tilt the lens downward, it is not seated deep enough.
- Tighten the bungee cord: Pull the adjustable bungee until the cap hugs the lens without compressing the hood or leaving gaps. A snug fit keeps wind from lifting the edge. Common mistake: leaving the bungee loose in wind or heavy rain, which lets water run under the cap.
- Check the taped seams and coverage: Run a finger around the edge to confirm the taped seams are flat and the cap covers the full front opening. Adjust the bungee if any seam is folded or twisted. Checkpoint: folded seams create a channel for water. Smooth them out before you shoot.
- Remove and dry before storage: When conditions clear, slide the cap off, shake off loose water, and let it air-dry fully before packing it away. Do not store it wet against the lens. Common mistake: storing a damp RainCap in a closed bag, which can transfer moisture back to your gear.
