If you’ve spent thousands of dollars on camera lenses, you might want to take better care of it. This comes in the form of keeping it in a Dry Box where it prevents the lens and the elements from getting overly humid, which in turn can cause fungus to grow and could ruin the glass of your lenses.
However, if you’d like to take your lens care to the next level, you might be interested in checking out this camera lens accessory created by a company called UN. As you can see in the image above, this lens cap is actually both a thermometer and humidity meter built into one, where it will show you the temperature and humidity levels of your lens.
This means that you’ll be able to check the temperature and humidity levels of each of your lenses, so you know if it isn’t too humid or too hot or too cold. If you don’t have a dry box, then this could possibly be the next best thing. Dry boxes can be a bit expensive but this particular accessory will only cost around $18.
