[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Yesterday I checked exposure with and without the UV filter I use on my lenses when shooting on the water. The subject was a sailboat on Buzzards Bay on a bright but hazy day. (The typical Buzzards Bay smokey southwester had filled in.) This is a situation ripe with UV. The exposure with and without the filter was the same to the accuracy I can measure it in Lightroom. So, the Nikkor 70-200 mm, f2.8 zoom with 1.4 teleconverter does not need a UV filter to expose properly on my D300 as Henning had predicted. Presumably, this is also true of other modern Nikkors.
