I shot a short, fun thriller this weekend. Just for the hell of it.

I used the AF101 with a mixture of Nikon stills lenses. It was my second time out with the camera and I am really loving it.

My only issue I found was that some shots had a magenta sheen across the centre of the image (which I am going to easily fix in the grade). I haven't investigated fully so I'm not sure if it is a problem with one of the lenses, the adaptimax nikon adaptor or just lens flare (I was using a mattebox for the first few shots but got rid of it because we were against the clock and it was slowing down lens changes.

Anyway, here are a few framegrabs. They are full res (1920x1080) but highly compressed jpegs which I've added a rough grade to. I haven't included any of the problem shots.

Would you mind posting up one frame grab with the issue showing please. I may be able id the problem (from recent experience)

BTW: nice frame grabs.
 
This is an ungraded shot with the magenta flare across the centre. It has been exported from FCP and then compressed as a Jpeg.

I have a feeling the flare is caused by the lens not being attached to the adaptor properly and that light has bled in somehow.

Yeah, it's most apparent around his black jacket, and then flaring off of it?
Is the lens/adapter connection physically loose- does it wiggle?
If so, when you wiggle it, does the flare come and go?

Nice grabs up top!
 
I just shot another short this weekend. On the first film I was the director and not the operator and had little interaction with the camera. I only noticed the magenta discolouration when I was looking at the rushes. This time I was the operator in a more controlled environment (interior lit locations) and I noticed the magenta flares as we shot and was able to deal with them.

It seems that the Nikon lenses I use are very prone to flares even from indirect light (one of the worse flares came from a reflection from a white wall). Now I know what to look for it's not a problem.
 
I used a mixture of adjusting the position of lights, flags on the matte box or barn doors on the lights and just using the palm of my hand to block the light hitting the lens.
