Sigma 18-35/1.8 flare question

Has anybody got a real life experience with this lens and shooting under strong lamps? These are shot with Nikkor 18-105vr with the lens hood on and the flare is... well. The small bits in the centre of the first photo are quite easy to retouch, but the huge bit in the top right corner of the second photo is somewhat nasty. Would Sigma behave better?

Re: Sigma 18-35/1.8 flare question

I have the Sigma 18-35 f1.8 for Nikon, I love it but it is sensitive to flare as well. I've been using it without the lens hood because I have a step-up ring on the front I've been too lazy to take off. Without the hood it will show visible flare artifacts, I can't say with the hood how much better it would be.

Oh dear. And may I ask what is the source of the flare in this picture without any shadows? Or is it shot in "behind the house" and so carefully composed that it is not clear that it is a sunny day and the sun is just outside the frame of the photo?

If you have a 1.8 lens and shoot directly at a lamp, what do you expect?  Of course you have flare. Those are the laws of physics.  Help me understand why this is a topic of discussion.

How come that some lenses are more prone to flare than others, even when the source of the flare is not directly present in the frame?

Would you kindly explain the physics in the photo in Brent Allen Thale's post in this thread, since there is no obvious strong light source present in the scene?

Sunlight or another source of light is being reflected off something like a car mirror or a whole hosts of different surfaces just outside the view of the camera.

Without a hood, ambient light could be cumulative giving you internal glare. Those goofy shaped hoods really work, amazing how 10 cents of plastic improves hundreds of $ in glass. I better be quiet or my next prime will be all plastic (lol).
