Anyone confirm the part circle marks on the bottom left corner is down to flare or something



Has appeared on several pictures over the last two weekends..........seems to be on the ones shot through a 105mm Polariser.

Ignore the spots of rain

now as u know im no expert, but i wouldnt expect a flare when using a polariser??? and if its the same place have u checked the polariser? could it be a streak when cleaning it etc? i know a guy who thought his camera has goosed (technical term) but he hadnt cleaned the lens properly.

Polariser's have several uses and one is to help reduce flare (although that does not mean they will always completely eliminate it).

Its hard to tell from just the one shot however looking at where the rings are in relation to the main light source I would say that there is a 90% chance that this is nothing more than lens flare.

If you have other example shots that you could post I would be happy to form a revised opinion based on those too

Hmmmmmmm!.Looks like lens flare,but doesn't.You've got a strong light source in the opposing corner so it's a possibility.Try cleaning both the lens and filter.Also,if you are not already using one,try a lens hood as well.I use Ixos screen cleaning tissues for filters,and a Hama DigiKlear pen(Excellent!) for lenses.Hope that helps.

Thanks for the feedback

As the polariser sits several mm away from the lens in a filter holder am I right in thinking this would/could create lens flare?

I will post some more examples in a sec.

Yes the larger the gap between any filters and the front element of the lens the bigger your chances are of introducing more/extra lens flare. When I am using the Cokin lens system I always attempt to slot in the filters as close as possible to the lens and I am acutely aware of the extra flare this can sometimes introduce.

This is what I thought Steve.

I have the Lee system with the polariser set two filter slots away from the lens (if you know what I mean) which results in a substantial gap when it comes to lens flare I guess.

I have polerisers as screw in filters directly on the front of the lenses and the cokin system I use for special stuff like hard or soft grads, this I obviously attach to the front of the Polerisers. I have found it to be the best method to keep the maximun quality and minimise the flare.

Never thought of doing it that way.

Here's one other example.......

Is this shot through an ultrawide? The reason I ask is that I had a similar effect on my 17~35 at the wide end when I tried out an orange filter on it. I found that unscrewing the filter made the effect move and then I realised that the mount was so thick that the lens was recording the outer edge of the filter. Just a thought...

These were @ 16mm using a 16-35mm

I will stick to my original verdict and say definately lens flare.

To confirm it beyound doubt, next time you are shooting under similiar conditions take the same shot with and without the filter(s). The results should vary enough to confirm one way or another.
