Get a filter to protect each lens from scratches
Even if you keep your lens cap on during storage, it’s not practical to keep removing and replacing the cap during shoots. Putting a clear or UV camera lens filter on each lens you have is a great way to help avoid lens damage and is worth the investment compared to repairing or replacing scratched lenses. Sometimes these filters can cause flares on your images though, so pay attention. You may have to remove the filter for some photographs.
