The Heliopan 25.5mm UV Filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. No additional coloration or contrast is provided, allowing you to pair this filter with others. The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.

Q: 1. Read a few reviews saying the lens cap doesn't fit quite the same once the filter is on the lens? I'm getting it for a Sony 24-70 2.8 GM so I was hoping you can still put the cap on over the filter? Thanks for the help!

A: Yes the filter has a 82mm front thread, the same size as the original thread on the 24-70mm f/2.8 GM lens. The issue is that the thread on the filter is not as deep as the thread on the lens. Some lens caps are made for deep mounting. In that case it is advisable to get a shallow mount lens cap: https://bhpho.to/31qeltG
