Biogon 35 flare?

[visiondr]

So, I was scanning this image today. Really, it's not much of a photo. Still, I think it illustrates something interesting.
Until now, I've been trumpeting the flare resistance of the Zeiss Biogon 35/2. I said "until now" because, as this image shows, the whole central area of this image is flared out versus the periphery. Yes, I was using the Zeiss hood and no filter was in place and the image is not cropped. The difference in contrast is obvious. Yuk :bang:

I could fix this quickly in P'shop or in a wet darkroom. Simply burning this area a touch would help a lot.

Your thoughts?

That's interesting given the rep of the lens on this forum.

I had the same thing happen the other day with my 15mm Heliar ... for no apparent reason one photo flared centrally under conditions that weren't really unusual and shouldn't have introduced a flare problem!

Your problem has to be something to do with the water surely ... I can't see anything else in the pic that would provoke it!

It seems to me the position of the sun in this shot might have something to do with it but then again the very sudden drop in contrast from the left side to the center is dramatic. It might very well be something going on with the water there and reflections. What I also find interesting is the middle tree there, the trunk is obviously a lot lighter then the branches or the other two trees in front. This is a bit of a noodle scratcher...

I thought so too. As I said, one very large circular burn in P'shop or under an enlarger would suffice to "cover" the issue. Still, the issue is there and it bugs me. The sun is outside the frame. Just look at the shadows of the trees to tell you its position. However, I'm in the shade, using the dedicated hood and no filter. Really, this might be a challenging lighting situation, but it shouldn't produce this... should it?

Just look at the level of contrast in the trees at mid horizon to the far left and right and compare those with the trees in the center distance. The difference is huge!

I know it is frustrating but flare can be a strange beast. There is also the possibility of moisture in the air above the water resulting a slight haze that your eye might not have percieved but the film faithfully recorded?? Anyway, perhaps you should ask yourself how much worse it might have been with a less flare resistant lens!
