Not sure if anyone has encountered these or not... Flare was from a 2k zip just out of frame

I think it's a telltale of some design choices... Any lens gurus want to weigh in on it ?

there are flares like this on Heat during the last driving sequence

All the RPP do this...at least, from my experience. I love it.

I haven't heard of this happening with any of the other primes. Grabs or it didn't happen.

I remember pointing the 25mm and 35mm at the sun, playing around for a long time, trying really hard to get flares. Nothing like this. Not even close.

I did see this type of flare on the first samples posted here of the 18mm. Not sure where the thread is. The one with the old teddy bear and BMW 3-series.

Here, I found the video in my computer: 18mm FLARE 1, 18mm FLARE 2, 18mm FLARE 3
 
In my opinion is hard to come to conclusions of anything with out knowing how each shot that produced each individual flare was captured.

But also I must say that I love each lens for what it does, Flare, Chromatic Aberration, Barrel distortion, and many other so called defects are infect carefully manufactured characteristics of each lens.

Un less off course totally screw ups, he he.

I happen to love flaring, and some times go nuts trying to get them artificially, so I love this effect on a lens, and this are amongst the easiest thing to avoid.

I Love the RPP's and RPZ's for their chosen characteristics.
 
But the limit is there. If you want a hot source in or just off the frame then it seems you will get these wave pattern flares, which are very strong.

If you don't want them at all, the it would seen you'll need to carry a second wide. Perhaps Duclo's PL 11-16 Tokina, on a budget. It does have pretty pronounced flares, but nothing like these. I might find these more pleasing, but they seem so overpowering, so big, and so hard to avoid noticing with this rainbow pattern. This would be especially practical with two cameras and a stand-by Canon/Nikon mount, which would let you buy the un-modified Tokina (~$600) and save a few thousand dollars, and rentals costs. There is always other far more expensive primes and trying to keep down the number of days.

Then again an 18mm is more of a widest-interior lens. With interiors you have control over light, but if you want a light here, and here gives you a flare, one that will not go un-noticed...

Perhaps the 14mm will suppress these better, then you'll likely be covered for most wide exts,and get others you wouldn't have gotten either way. Or perhaps the 17-50mm!!! I hope the zoom doesn't get this sort of flare.

Lets not forget the thousands of gorgeous images you can get with the 18mm! The videos posted have some very beautiful images, tons of sharp detail and that cool 18mm perspective.

And you always have to mention cost!!! Can't beat them in aspect either.
 
James, you can't block something you want in your shot.

Sun in the shot without the rainbow flare: 18mm FLARE Good

And here are a few shots to enjoy some of the pros of this gorgeous lens: 18mm DETAIL #1, 18mm DETAIL #2
>> Keep in mind that these are screenshots off an h.264 QT, and saved as JPGs!

I wish I knew the name of the poster to give him credit here.
 
Just curious... have you tried a net in front or behind the lens with a flair?

If flairs are as important as the image quality id pick another lens.

Try Hawk or Lomo Round Front Anamorphics - http://www.vimeo.com/9125933 - for great Lomo flairs in action.

When you are shooting 2K better use 16mm lenzen!

Imagine that you have a big hole, the back of your lens (5K ready) in front of a small sensor (in 2K).

Use a france flag (the stiff one of course, LOL)

Kind regards Robert

WTF, sky replacement and they didn't bother to fix the "black sun". FAIL. Sorry, couldn't help myself.

I curse you for making me sit through that whole song looking for it. With those haircuts the sun is the least of their worries. :) But it looks like they left it there on purpose, and blurred it.

Ummm... I believe Matt was saying he was using a 2,000 watt light and not shooting 2K resolution...

I think Matt was putting it out there to see if anyone had any ideas as to
what in the lens design/optics would create that particular kind of flare.

He's quite familiar with French flags and/or grip flags for eliminating flare--that wasn't his question.

And yes, a 2K zip is a light (concave white interior with globes on the bottom--no lens, so it creates a bounced, softer light).
 
I think most of this is in the coating, possibly somewhat in the glass composition. I've shot quite a bit with the RPPs, as I own a full set with 18mm and 300mm, and haven't had any real issues. I don't think I have the rainbow flare like this in any of my footage. Although I have seen it. It's kinda unique, but I suppose it could be undesirable due to how intense it can be, based on these examples here.

Uh... It's in the first several shots and like constant throughout the whole video. I don't know if they actually did full sky replacement - unlikely with all the flares. But they did incorporate the jolly roger cloud formation and didn't mask the black sun spots in the middle of their blown-out hotspots. Sorry, it's just one of my biggest peeves with RED post. So many people who shoot or post with RED don't bother to fix this when it's so simple to do so. Maybe they wear it like a badge "shot on RED, see my black spots!". All my clients always want it fixed, it's like the first thing they see and some even freak out over it.

Oh, missed those. I was blinded by the hair. Once I regained my sight I noticed a few towards the end with the setting sun.. :)

I assumed it had something to do with the coatings. What I don't understand is why it shows on the 18mm and not the others..?
