Fighting Lens Flares for Emotional Impact: A 7S III Learning Curve

I recently shot a short film where we wanted a protagonist's emotional breakdown to feel raw and overwhelming, almost like the world was closing in. My instinct was to lean into practical lights as flares, so we rigged a couple of Astera Titan tubes and an Aputure PavoTube II 30X behind the actor, just out of frame, pointing right at the lens. We were shooting on an a7S III with a set of vintage Super Takumar primes, specifically the 50mm f/1.4, hoping to get those characteristic soft, colorful flares.

What worked, initially, was the overall bloom and haziness the unprotected elements in the vintage glass delivered. It gave the scene a dreamlike, almost suffocating quality, which was exactly the mood we wanted. The skin tones held up surprisingly well even with all that light washing over the sensor. However, what didn't work was the sheer unpredictability of the flares. On some takes, we'd get beautiful, organic streaks; on others, a massive, distracting blob of rainbow where the actor's face should have been. It was too inconsistent to cut together seamlessly, and attempting to 'dial back' the tube intensity often just killed the effect entirely, leaving us with just a glow. We ended up having to introduce a 1/8 Black Pro-Mist filter to add a global softening and help merge some of those harsher flares into a more consistent diffusion, which tamed the extreme, ugly ones while preserving the atmospheric haze.

It made me wonder: for scenes demanding consistent, yet intense, lens flare effects for emotional storytelling, are there specific lens coatings or even digital techniques that offer more controlled chaos than just brute-forcing it with practicals and vintage glass?
