Sigma 14-24mm f2.8 Flicker Issue

Hi all,

 

I'm just putting this out there for anyone who has purchased the Sigma 14-24mm f2.8 lens.

It has a factory issue where it has an uncontrollable flicker. However, there is an update that fixes this.

 

Unfortunately, I didn't know this was the case so it ruined my footage from a couple of weddings I shot recently. The flicker is insane and I don't know what to do to fix it. I asked once before on here and I got a temporary/minor solution where I downloaded a plug-in called "flicker-free" and it vaguely removed the flicker.

 

I'm really worried I can't save this footage and if anyone has any suggestions on how to fix this it would be greatly appreciated and you'd be a lifesaver at this point. I've tried everything 😞

 

I've contacted Sigma about the issue and they wouldn't take responsibility for their faulty product.

I honestly hope no one else has this issue because Sigma will do absolutely nothing to help the situation.

 

Thank you in advance!

 

(Example video attached below) Also, I have footage that is flickering way worse than that one..

I was as surprised as you. As you saw (with the red x over the footage) my Boris BCC subscription has expired ... so I tried Digital Anarchys 'Flicker-Free' and RevisionFX's DEFlicker first - both I thought would be the better options. But no. Have to hand it Boris on this occasion - the end result was pretty amazing.

 

Hope it works well for you too.

I tested your shot with Boris Continuum Flicker Fixer and got some pretty good results (see linked clip below). This might be what you need. Certainly worked better than I thought it would. I did find slightly better results by grading the shot first with Lumetri to fix the overexposure slightly (particularly in the clouds) before adding Flicker Fixer.

    Steve! That is incredible!

     

    It looks as though the flicker is completely gone!

    I am going to try it on my end and get back to you with an update.

     

    Thank you so much!

    Strange. We actually just got one of those lenses at work but I haven't used it yet. I will keep an eye out and thank you for sharing. Was the fix a firmware update through their website?

    I actually had to take it to the store where I purchased it. They had to update it through an external dock. They even charged me for the update. I wasn't able to update it through my Sony a7iii.
