We always have large stocks of used filters on sale here at our store in Bicester, Oxfordshire, but every now and then we have too many, so you'll often see a small selection of different types appear here on our eBay store

A skylight filter:

• is slightly tinted to correct the excess blue cast from sea, sky, and high altitude photographs
• is an excellent lens protector on bright sunny days
• is coated or multi-coated for flare reduction
• cuts out UV rays to give astounding sharpness and clarity without affecting colour balance

This is a Japanese-made Hoya 72mm Skylight 1B protective filter from the 1990s, in good, unscratched & blemish-free condition with a perfect rim.
