Strange Lens Flare (Sigma 35mm + MRC filter)

[Cinto]

Canon 5dmark2 with 40mm 2.8. Maybe related to focal length too? Different, but close.

You're correct, I can see a blotch in the shy to the right...

I think it might just be flare, check this two pics. Flare both in and out of the frame, unless the mirror is reflecting in the middle as well as the edges.

One more cause I found it. It may be the mirror but it's a combination of mirror and lens I'm pretty sure, I never really saw it on the 35L. Maybe the curvature of the back element make s a difference?

I think the Sigma 35 does make the camera more prone to showing this effect. Fortunately now that we know why this occurs we can at least take it into account and turn the body 180 degrees if necessary.

Just want to add that I was shooting with the 5D2 late last night with my 24-70 f/2.8 II and experienced this same sort of flare in one or two of my photos. I put it down to the filter at the time, but after reading this thread regarding the phenomenon occurring with only the 5D2, it makes sense as I've never seen this lens have that flare on my 5D3.

Looks like its nothing to worry about. I'll post my flare picture tomorrow from the 5D2 and 24-70 II.

Wow, I was blaming my Siggy 35mm, although I liked the "anamorphic lens flare" feel, it would only occur shooting vertically so I couldn't understand the issue. Consequently I haven't gotten any of this since moving up to the MarkIII...

That would be interesting, please post the pictures

I also decided it's not something to worry about, rather just be aware of. in 32000 images I took with the 5D Mk II only a few pictures show this effect which, depending on ones preferences, may be disturbing (or not). In any event, I'll try to avoid its occurrence in the future when I use this camera body.

Here's my snapshot from the other night.

Like I said previously, I thought the flare my just be caused by my filter. After reading this thread I'm 95% sure it's just the mirror box in the camera now. Not a big deal... I've never had this type of flare before in any image that really counted.

Thanks for posting, it's the familiar flare alright. It looks like there is a small spike in the snow on the road as well... At least it's confirmed it does not only occur with Sigma lenses, and given the right conditions, almost any lens can produce the effect on the 5D Mark II, at least those with a wide aperture.
