The 67mm Protection Filter from Heliopan is more than a wise initial investment. It not only keeps dirt and grime off your valuable optic but keeps the front element safe, thereby avoiding costly repairs.
A Protection filter can not only help minimize the bluish cast sometimes found under cloudy or open shade conditions, but it is also the best available protection against accidental damage to the front element of your lens. A lens that accidentally gets dropped on its front element while hiking can potentially be saved by purchasing this item. Some people refer to a Protection filter as "cheap insurance". As a lens protector, it should be left on at all times.
The reputation of Schott glass is world renowned. The high production standards combined with a sturdy brass filter ring make these filters hard well worth the investment. Heliopan filters have a "feel" that is distinctive. They may feel heavier than other protection filters from other companies but the benefit is in the construction and results. Not only is the glass exceptional but so is the seal between the ring and glass. Schott Glass used in the manufacture of this filter is legendary and synonymous with the highest standards of filter production.
The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability.
Heliopan has been a leader in the filter industry since 1949. They are known for their high quality and production standards. Their slim mounts facilitate using them with wider angle lenses. Heliopan offers most of their filters with either their standard hard coating or with their industry leading SH-PMC 16 layer multi-coating that transmits over 99.5% of the light striking it on to the image plane for the lowest flare and greatest color saturation. As a benefit, the top layer of the filter prevents dust and moisture from accumulating on the filter surface.
