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.
This will make it a cheaper option for you if you only have one or two lenses or if you don’t want to invest in a proper dry box. While it won’t protect your lenses the same way as a dry box, it at least lets you keep an eye on your lenses. It is also not powered by batteries so you don’t need to worry about it suddenly stop working.
