I mean even the best lenses will have flares if you point them into a light source. It’s absolutely possible the noct has an issue but I’d say it’s incredibly more likely that it’s just an unfortunate flare. I mean looking at them it’d be super easy to take out editing wise. Can we see the full image? Cropped doesn’t really show the lighting

I mean if you REALLY wanna do it in house you are gonna spend more than 1000 on equipment easily not to mention paying whoever will do it. A skilled photographer could do it on a lower budget, especially because they’ll bring their own gear. But having an employee LEARN photography??? Crazy dude
