So I guess I did it wrong...
I bought the well-regarded Tokina 20-35mm (the slow one, 1st version), and it halos like nothing else going.
Almost as if the lens is fogged whenever there is bright light in the photo...
I get things like this (which are worse at high ISOs, but this isn't a high ISO...)
And when I try and remove the haze, it just turns the photo into a mess...
But when the lighting behaves, generally when I use flash inside, it is terrific.
Both of these are straight out of the camera apart from the resizing between Photos and here...
I don't see anything when I look in the lens in terms of haze, fog, or fungus.
I read something about "dark fog", lubricating oils that migrate to the interior elements but don't show in the flashlight test. I'm not sure if that's a thing or not...
Anyway, it makes the lens nearly unusable.
Any ideas? I really want to like this lens...
It also shows up in Photos as a Tokina 19-35 unless I'm shooting at 35mm, when it thinks it might also be a SMC-F 35-70 f3.5-4.5
