Menyerap sinar ultraviolet yang sering menjadikan gambar luar kabur dan tidak jelas. Penapis serbaguna ini boleh berfungsi sebagai pelindung lensa tetap. Walaupun direka khusus untuk kamera digital, siri Zeta juga boleh digunakan pada kamera filem.
Teknologi Optik Superior
Ia menggunakan kaca optik dengan penghantaran tinggi, yang dapat menyekat sinar UV di bawah 300mm. Tepi lensa telah melalui pemprosesan matte untuk mengelakkan silau yang berbahaya.
DMC Pelindung Air & Minyak Multi-Coating
Salutan DMC mempunyai 8 lapisan Pelindung Air & Minyak, Tahan Calar & Kotoran di Setiap Sisi. Salutan ini memenuhi keperluan standard salutan optik, yang telah melalui ujian rendaman air garam yang ketat.
Rangka Super Slim
Ketebalan rangka hanya 3.5mm menjadikannya sangat sesuai untuk lensa sudut lebar, yang dapat menghapuskan vignette. Rangka ini telah melalui standard EU ROSH, dan selaras dengan keperluan alam sekitar.
Data Ujian Daisee menunjukkan bahawa:
Penapis tanpa salutan boleh memantulkan kira-kira 8% cahaya, yang mengenai dua permukaan sentuh udara kaca; sementara kehilangan cahaya penapis multi-salutan hanya 0.5%. Teknologi multi-salutan memainkan peranan yang sangat baik dalam mengurangkan silau dan pantulan cahaya. Penapis multi-salutan Daisee mengurangkan kemungkinan silau dan pantulan dari kira-kira 8% kepada 0.5%, yang bermaksud pantulan dikurangkan 16 kali.
Absorbs the ultraviolet rays which often makes outdoor photographs hazy and indistinct. This multi-purpose, all-around filter can serves as a permanent lens protector. While designed specifically for digital cameras the Zeta series can be used on film cameras as well.
Superior Optical Technology
It employs a high transmittance optical glass, which can effectively block UV rays below 300mm. The edge of the lens has undergone matte processing in order to prevent harmful glare.
DMC Water & Oil Repellent Multi-Coating
The DMC coating has a 8-layer Water & Oil Repellent, Scratch & Stain Resistant Coating on Each Side. The coating meets the standard requirements of the optical coating, which has been put through rigorous Salt Water Immersion Tests.
Super Slim Frame
The thickness of the frame is merely 3.5mm making it perfectly suitable for wide angle lenses, which can eliminates vignetting. The frame has been through the EU ROSH standard, and is in line with environmental requirements.
Daisee Testing Data indicates that:
Those filters without coating can reflect about 8% of the light, which hitting on the two air-contact surfaces of the glass; while the light loss of the multi-coated filters is only 0.5%. The multi-coating technology plays an excellent role in glare and light reflection. Daisee’s multi-coated filters decrease the possibility of glare and reflection from approximately 8% down to 0.5%, which means reflection is reduced 16 times.
