What is an ND filter and what with all the numbers?
In photography, a neutral-density filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition.
I recently purchased a Sony 28-135 f4 G OSS and found myself in need of a 95mm ND filter. Have a both a Rodenstock 77mm variable ND and an LCW Fader ND 82mm variable, but obviously they are not big enough.
Also the filter needs to fit under the Sony sun hood, and the Tokina seems to fit.
I decided to go with Tokina IRND filter, which has gotten good reviews. Settled for ND 1.2 (for a startup) Will prob. get additional later…
Searching for filters I got pretty confused with all the numbers, which I had been before, so I thought “now it time to learn”.
Here is what I found, brought into an easily read table, saved as a picture which can be downloaded to your computer, phone or tablet.
I will update this post when the filter are in house and I have tried them.
