Hoya Digital Filter kit 58 mm Filter

All three filters are useful in different scenarios, and this is a cost-effective kit. Hoya is one of the world's biggest names in optics. The image quality with these filters is excellent. The Circular Polarizer is very effective for contrast and well-saturated color rendition in outdoor shots. Makes reflections vanish magically. You can control the degree of polarization by rotating a ring around the glass element, even after the filter is fixed firmly before the lens.

The ND filter (8x, 0.9, 3 f-stops) is truly neutral, no color casts were noticed. To get an additional 2-stops of darkness, one can stack the polarizer over the ND filter for 32x, 1.5, or 5-stops of darkening. Allow really long shutter speeds even in bright scenes. But will get vignetting due to the filter rings on wide-angle lenses with this much stacking.

Multi-coatings on glass surfaces really reduce unwanted reflections inside the lens from light sources. When there is a direct light source in the image (say, a lamp or candle flame), even a hood does not help, so coating important.

As for Flipkart, the product got delivered in 2 days, and was packaged as if it had to pass through some war zone. Good work.
