The Tiffen 2 x 3" 3 Twilight Graduated Filter (Vertical Orientation) helps to specifically add a unique deep magenta to pink gradient to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a soft-edged transition between the density and clear areas. The 3 color density provides more twilight coloration than the 2 density filter.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 2 x 3" / 50.8 x 76.2mm.

3 Density Color Graduated Filter    Twilight Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a unique deep reddish magenta to pink gradient across half of the filter plane.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.

A vertical orientation filter's line of transition runs parallel to the short side of the filter.

Q: 1. How well does this lens work in low light?

A: This isn't an exceptionally wide aperture, so if low-light performance is your top priority, I'd recommend looking at the 70-200 f2.8, or changing your body to an A7s. However, I've been shooting with this as my everyday lens on my A7ii for over a year and I'm very satisfied with the performance in all conditions. I recently tested it against a G-master lens and was surprised that the difference in the image quality was extremely marginal.
