So you’re using a filter on your lens, maybe to protect it from dust or finger smears or maybe for an effect that you want, what can you do to ensure that it does not degrade the quality of your expensive lens? Here are some pointers:
- Buy a good filter. A bad filter can do more harm than you expect.
- Never touch the glass of the filter. The oil from your skin will rub off on the filter and could damage it’s coating. Some filters, are noted to retain fingerprints if not cleaned up immediately. Always touch a filter by the edges.
- Store filters in their boxes. This ensures that dust and fingerprints stay away.
