| p.1 #1 · p.1 #1 · Strange flare w/135mm, Sony A7RII - flare reduced when upside down? |
So, I haven't shot much with the Rokinon 135mm F2.0, and was playing around with it today, indoors when I noticed a strange flare/reflection I never noticed previously. I thought I might have done something to my camera, or the lens, but couldn't figure out what it might be.
I've played around with the lens previously, and never noticed anything like this.
The lens is being used adapted - from Nikon to FE (A7RII) and I see the reflection when used on an inexpensive dumb adapter, or on the TAP, and I cleaned both.
I don't see a flare with other lenses at 85mm or 100mm, using the same Nikon adapters.
I don't see a flare on a C/Y 135mm.
The flare is reduced when I turn the camera upside down.
The flare is significantly worse when stopped down.
It may be present wide open, but it's dependent on lighting - light at my back and I don't see it.
The flare largely goes away if I block about a finger's width of the lowest portion of the lens, without blocking the FOV when shooting close up.
Using a hood doesn't seem to make a difference.
In these photos the sun was on the left, and would come from over my right shoulder, if I were outdoors. Window was on the left at about the same height as the camera, so no direct sunlight was hitting the front element.
Is this a property of the lens design and the lighting?
What's going on?
I was thinking about buying another 135, but really don't want to spend the $$, if another fast 135 will behave similarly.
