Yes
In the below image i was shooting in bright conditions sometimes towards the sun, but it was high in the sky, and my Sigma 100-300 f4 has a massive lens hood to prevent flare. As you can see the bottom right hand part of the image looks very hazy. This only happens occasionally. Is this caused by lens flare??

Any help as to what it is, and how i can prevent it would be much appreciated.

it looks like something has passed infront of the lens to me, i've had similar shots before
 
You wasnt behind metal railings were you? I have had this before when I had
the camera too low.

definately not as it happened on a few shots today and Ive experienced it occasionally in bright sunlight before with this lens on a different body. Besides i was at 1/1250s so id of thought anything passing the lens would fully obstruct the shot?

nope. Pitchside
 
I think that's flare which might even be caused by the lens hood, if it's not properly black and even a little bit shiny perhaps?

Black flocking is best. What is the hood lined with?

Is the filter thread shiny metal?
 
I agree with HoppyUK, large hoods can cause this if shiny on the inside.

Filter thread isn't shiny and the hood is ribbed on the inside, and it is a matt finish but just looking at it in light now it is actually a little reflective - strange..... the inside coating is more 'shiny' (whilst still being matt) than the coating on the outside of the hood. I suppose this could be to blame.
 
looks like a horizontal band of very translucent material...sort of cokin effect

strange phenomenon
 
Large hoods are often shiny on the inside, which can cause some oddities on part of the sensor when shooting towards the light - why can't they be made matt / non reflective...........:cuckoo:

I am more concerned though with the winger (No 11) playing in tights and green boots. You'd have to be at least Banahan/Monye standard to carry that off. Or Widow Twanky!
 
Looks suspiciously like Lens flare from the inside of the hood to me too...
Sigma's are very susceptible to flare as I found to my cost, I'm afraid...

Lynton, the Gok Wan of the rugby world:D
 
The 100-300 hood doesn't have any form of coating on the inside other than the EX coating. I found mine was likely to flare in similar conditions - call it a feature.
 
Using any kind of UV filter or something like that?
 
Looks like in-hood reflection to me too. But I am no expert.

Can you retro flock coat the inside of the hood, like a dashboard, to prevent reflection? Think some of the old Nikon 17 or 20-35mm hoods have this done.
 
I would pop down to Halfrauds & get some self adhesive velcro tape & line
the inside of the hood & se if that eliminates the problem.

Or get yourself one of these & flock everything :lol:

maybe it was the green boots causing dazzle in the lens :eek:
