p.1 #15D2: what is going on here???
Took this shot this afternoon with my 5D2 + 35mm f/2 (ISO400, f/11, 1/640). The sun was high in front of me when I took the shot. There wasn't any flare visible in the VF when I composed the shot. But when I released the shutter, I saw a bright flash in the VF, and this bright streak appeared in the right top corner.

100% crop of the "streak"... When you look closely, you see a grid like pattern:

What is going on here? Could this be due to internal lens reflections? And what is the grid pattern about? Is it the sensor?
Thoughts?

someone with a bad sensor-channel relative boost got those weird patterns before
maybe the sun somehow hit something inside the camera and bounced up onto the sensor

I assume it is always visible in that case? I have only seen the grid-like pattern in this particular shot.

Well, the 35mm f/2 is an old beast... and without all the modern coatings. Weird...

If you had used fill flash, the branches and foilage wouldn't have been so dark, and the grid pattern invisible. 
Sorry, I haven't seen this before.

No flash would have been powerfull enough to fill in those branches and foliage. But that is besides the point. Even if I would have used fill flash, I still would have gotten the weird streak with the grid like pattern...
My guess is that the sun light bounced inside the cam and caused some kind of system overload resulting in this grid-like pattern.
Yep, this 5D2 is full of suprises...
BTW The grid-like pattern is only visible around the streak... the rest of the frame shows no grid-like pattern.

I was just joking, Daan, with reference to the shadow noise discussion. Thought you knew my position there that well

Maybe some kind of alien spaceship is about to land in Holland 
? Just kidding. Definitely some kind of lens flare. Why it wasn't visible on the VF before the shot is beyond me. Are you using a lenshood? Has the inside portion of the lenshood some kind of black flockings or are there ridges on it? I am shooting from the hip here...

Yeah, there are coming to reveal the 7D to us
I had the lenshood on... the kind with the black flockings on the inside. No flare visible in the VF. When I released the shutter I was almost blinded (well...) by the light flash that followed. Weird stuff.

When the mirror is down, there are other reflections inside the box than with the mirror up.

Come to think of it... this "phenomenon" reminds me of the Nikon D200's short banding issue at high contrast edges (http://support.nikontech.com/app/answers/detail/a_id/13872).

+1 ...The internal reflections would undoubtedly be different and could (potentionally) cause flare that would not otherwise be seen with the mirror down. I wonder if you might be able to repeat this phenomenon by setting up a similar shot and switching back & forth from live-view to see if you create the same type of flare.
HTH,

Not alien space ship. You might have caught Superman streaking past and caught some air turbulence.

Smoking too much marijuana and the smoke has messed up the shutter (sticky)?

p.1 #175D2: what is going on here???
It seems to me there are really two issues here:
1) An "issue" that caused the bright streak (probably mechanical)
2) How the 5D2/sensor reacted to that bright streak (exposing a grid-like pattern)
I tried to replicate it this morning, but with no weird results.

I would say it is lens flare that has caused an internal reflection and the sensor has bloomed. Those blotches are certainly machine-made. It's like the light has hit the sensor at the wrong angle and shown up the pixels. Odd.

I am wonder how does the 5D2 camera handle if you have camera in AI Servo AF and multiple shots has been taken during this condition

Looks lens or filter flare to me.
My 50 1.8 does this if I am not careful. I just take another shot when it happens.
