ProTama SQ-100 HD Nano MC Square Filter - 2mm ultra thin German Optical Glass, long lasting silk screen printing
Overview:

ProTama square filter is made of German Schott B270 optical glass.  The use of Schott optical glass gives our square filters the excellent properties of chemical resistance, high-temperature resistance, and abrasion resistance.  With an ultra thin noble metal multi-coating, ProTama square filters are a low reflection and able to avoid color differences while it also being water, stain, and scratch resistant.

HGND (Hard Graduated Neutral Density)

The filter is a hard half neutral density and a hard half clear.  As the limited latitude of digital cameras cannot allow for shooting environments with strong light/dark ratios, GND filters are often used to balance the light contrast between strong and weak light.



ProTama SQ-100 HD Nano MC Square Filter -  2 sides Nano Multi-Coating, 2 sides Water & Oil Repellent Coating, 2 sides Scratch & Stain Resistant Coating
The ProTama SQ-100 Filter applied 2 sides nano multi-coating with water-proof, anti-scratch & oil resistant which also be much easier for clean up.


The traditional neutral density filter isn't perfect since they don’t reduce the intensity of all wavelengths equally.  More importantly, a good quality of ND filter should perform an equal wavelength. To have a good performance, we spent a long period on grinding and polishing with our Germany Optical Glass during the manufacturing process. This greatly produces a smooth and balanced surface of HD quality glass.  With a rough surface glass which will cause diffuse reflection and it’ll affect telephoto zoom lenses couldn’t in focus.

We concern your filter
The ProTama SQ-100 Square Filter will include a soft leather pouch and a microfiber cleaning cloth. We want to keep the optical glass square filter in a safe area when you're not using it.  To avoid dust and oil on a square filter, such like the fingerprint, a large size of cleaning cloth which is the must.  We included a 25x25cm of microfiber cleaning cloth in the package.  We expect the filter will keep it safe and clean all the time.
