Hazy Low Contrast with 17-35 @ f/2.8

While shooting the mosaic comparison series with the nine different lenses at 17/21/24/28/35mm, I observed that the Nikon 17-35mm f/2.8 was more of a challenge to focus wide open at f/2.8 using Live View because of ultra low contrast, an effect I’ll call “haze” or “hazing”. For that reason, I focused at f/4, which helped, but did not banish the haze.

The haze is/was visible in all crops at all apertures, though the sharpening applied for presenting the mosaic crops masks the effect to a significant degree, by increasing the contrast.

It’s no mystery to see it in the final images, because a Live View gives real time look at the effect, and also proves that it’s not a focus issue, because there was no better focus or contrast to be had.
