Forgot which mm

Would you guys say this is 3.6mm? I bought it years ago and in the next month I'm hoping to replace with new bullet.i don't remember exactly what's the mm.

Without knowing he distances involved it's impossible to even start to guess.

Here's a chart that might help. It's an approximation but even that's better than nothing.

Brand and model of the cam? That might help.
