UV Filters: Do You Need One for Every Lens?

Learn when a UV filter makes sense for camera lens protection, how to choose the right size, and which lenses benefit most.
Quick answer
A UV filter is primarily a sacrificial lens protector. You don't need one for every lens, but it's a smart choice for expensive front elements or when shooting in dusty, sandy, or splash-prone environments.
Why UV filters matter less for digital cameras
Film cameras relied on UV filters to reduce haze, but digital sensors already block most ultraviolet light. Today, the main job of a clear UV filter is mechanical protection: it shields the front lens element from scratches, dust, fingerprints, sand, and accidental splashes. If you never shoot in harsh conditions, you might skip it on cheaper lenses.
The trade-off: protection vs. image quality
Adding any extra glass in front of your lens can introduce flare, ghosting, or a slight loss of contrast, especially with cheap filters. High-quality multi-coated filters minimize these effects. The Lens-Aid UV filters use Schott B270 optical glass, which stays color-neutral and sharp. Still, if you own a very high-end lens and always shoot in controlled conditions, you may prefer no filter at all.
Decision rules for buying a UV filter
- Check your lens's filter thread size: Look for the Ø symbol (e.g., Ø58) on the lens barrel or under the lens cap. Common sizes include 39 mm, 52 mm, 55 mm, and 58 mm. Buy the exact size that matches.
- Decide based on lens value and usage: Use a UV filter on expensive lenses or lenses you take to beaches, forests, or dusty urban shoots. On cheap kit lenses, the filter may cost nearly as much as the lens itself — consider skipping it.
- Choose a filter that stays on permanently: Once screwed on, a UV filter can live on the lens. Clean the filter glass with a microfiber cloth instead of touching the front lens element. Replace the filter if it gets scratched.
