Sigma PL filter, CIRCULAR PL FILTER 95mm. Purchased from Arai Camera for approximately 48,000 yen. Attached to a lens twice, but has not been taken outdoors. Works without any problems. It has the effect of removing reflections from glass and water surfaces, and enhancing contrast in landscape photos. Significantly suppresses light reflection and reduces flare and ghosting. Achieves a visible light reflection rate of 0.24%. In addition, the excellent water-repellent and anti-stain function strongly repels water droplets, and fingerprints can be easily wiped off. Furthermore, the self-lubricating function of the WR coating achieves more than 10 times the scratch resistance compared to conventional multi-coatings. It also has an anti-static function, suppressing the adhesion of fine dust and dirt due to static electricity, and even if they adhere, they can be easily blown away with a blower, etc. No claims and no returns accepted.
