The Heliopan Bay 1 Clear Protection Filter is a simple, clear filter designed for general protection to the front of your lens. This optically clear filter helps to reduce dust, scratches, moisture, and other elements from damaging your lens without affecting the overall image quality.

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: 5. Will this lens work on my Nikon D90. I have one lens that is 18-105mm and another at 70-300mm

A: No, this is not the proper sized filter for these two lenses. The Nikon 18-105mm lens uses 67mm sized filter, and depending on which 70-300mm lens you have it could be either a 62mm size or 67mm sized filter. If you have the lens cap for the 70-300mm lens, simply remove it, and look on the underneath side of the lens and it will state filter size. Below are two links, the first is for 67mm sized filter recommendation, the second is for a 62mm sized for you to regard on our site:http://bhpho.to/1gI9JCAhttp://bhpho.to/ISN5vR

A: It does come with a plastic case than it can be stored in, if you want more protection, could always get a mini hard case for these as well.

Q: 10. Why not use a snug fitting $5 rubber lens band over the slot when a filter is not desired instead of using this $130 piece of clear glass?

A: The glass filter would act as a barrier between the sensor and the lens mount to prevent any dust/debris from entering the camera.
