Sigma 77mm Protector LPT-21 Filter
Product Code: G331350G
Share this item:
Keep your front lens element protected against dust, dirt and scratches with a transparent 77mm filter that won’t affect colour reproduction or exposure.
Summary
A clear cover over the front element is a simple way to guard against dust, dirt and scratches, especially useful outdoors or where you’d rather not clean the glass directly. Colourless and transparent, it can stay in place for everyday shooting without affecting colour reproduction or exposure.
This generation revises the frame’s surface treatment to reduce internal reflections compared with earlier versions. Compatibility has also been verified across the manufacturer’s own range, including ultra-wide-angle models without vignetting, while secure cap attachment is retained.
Frequently Asked Questions
How do I know whether it is the right size?
Check the front of the lens barrel or inside the cap for a Ø diameter marking. You can also find the thread diameter in the manufacturer’s specifications.
Can I use it with another brand?
Yes. Thread diameter determines fit rather than manufacturer, so it can be attached to another brand with a compatible 52mm thread.
Can I leave it on permanently?
Yes. That’s one of its intended uses. The glass is colourless and transparent, with no effect on colour reproduction or exposure.
How is this different from a UV version?
This model concentrates on physical protection. The PUV-21 also cuts ultraviolet light to help prevent a bluish tint in sunny conditions and adds water and oil-repellent, antistatic properties.
Will it cause vignetting with a wide-angle?
The new range has been verified across the manufacturer’s own line-up without vignetting, including ultra-wide-angle lenses. Compatibility with third-party products will depend on their individual construction.
Can I still fit the cap?
Yes. Secure cap attachment is retained, allowing the protector to remain in place between shots.
