Introduction The Marumi FIT SLIM Circular Polarizer is especially well-suited to whom coating is not mandatory. Both hue reproducibility and high saturation color reproducibility are achievable simultaneously. While color neutrality is given priority, the transmittance rate remains approx 30%. (400-700nm average) Realized a thin aluminum frame to avoid vignetting even with a wide-angle lens Lightweight and rotating mount structure Made in Japan, indurated lamination technology by decades of technical succession. What are the benefits of using a polarizing filter?Why is polarizing filter recognized among most photographers as an essential must-have filter? Does Photoshop or other equivalent editing tool work instead of polarizer? A polarizing filter allows you to;– control reflections from non-metallic objects; the surface of water, window, or glossy coating/painting.– prevent and reduce glare, still however, allow plenty of light through. It also makes subjects underwater transparent.– Enhance color saturation and contrast, especially under a scene of deep blue sky, vivid white clouds, spring greenery, or autumn color of leaves. Have you ever experienced, when taking landscape photography, ending up with a little different color from the actual landscape you have seen? The sky must have been more vivid and bluish in your eyes.A polarizing filter can properly contrast the crystal blue sky and the white clouds.Many photographers predominantly carry a polarizing filter, particularly for landscape photography next step after Lens Protector/UV filter in terms of protection, for some reason.The effects of polarizers cannot be easily mimicked with digital editing. Carrying a polarizer makes your image more vivid and clear, turning the actual landscape you’ve seen into your picture.
