The Tiffen 77mm Center Spot Filter for Photographyis a softening filter that allows you to maintain sharp, clear focus in the center of the image while blurring the perimeter of the frame. This helps to isolate your central subject matter while softening the surrounding areas.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Maintain Central Focus and Soften Edges    Isolate Subject Matter    ColorCore Technology

Clear central area of the filter keeps subjects in the middle of the frame in focus while softening surrounding areas.

Helps to isolate subject matter and lessen distracting backgrounds.

Q: 1. Hello, I did read a review telling that when using a IR/UV Cut filter on Wide Angle Lenses the image can be compromised: the interference varies with the angle of incidence of the light on the glass. This renders this filter unusable with wide-angle and even normal focal lenses, resulting in a greenish gradient from the center to the corners. - this was posted for the 72mm version of an IR/UV Cut filter of another brand.- Q: Did someone else has this problem on Full Frame & APS-C DSLRs with Wide Angle Lenses like 16mm with THIS Tiffen W77IR filter?Thank you very much!

A: Hi HD Cam T,I purchased this filter to correct a known IR contamination defect in the Sony EX-1 camcorder. Black suits turn different shades of brown depending on their material without the filter. An orchestra of black suits will look like everyone is wearing a different shade of off black tuxes. But some will be true black. I only use the filter when I need it. I manually white balance the camera when using the IR filter. The image has a green cast if you do not white balance. You also loose about a half an f stop with the filter. Not a perfect fix for my camera but it is the only one I have found.

Q: 2. Considering this filter for the Sigma 50-100mm f/1.8 DC HSM Art lens, so vignetting should not be an issue for a telephoto. However, lack of front threads or provision for a lens hood is an issue. Is there a solution?

A: Hey Danny I haven't found a solution for a good, but never look hard after a solution either. I use it with my L series zooms and I can't never use lens hood with it. It is one of the smallest nd out there but still not small enough. Hope it helps
