Best Aftermarket 2x-4x Lens for Capturing Surfing ?

[Cosmosent]

My starting point is an 11 Pro Max.

I've used the Telephoto Lens @ Windansea here in La Jolla quite often, usually with a Monopod & an iPhone mount.

Generally, I've NOT been happy with the results.

I don't capture with Digital Zoom, ONLY what the lens itself is capable of.

I'm now looking at two options:

i.) 4x that attaches to the Back Wide Camera

ii.) 2x that attaches to the Back Tele Camera

Anyone have ANY experience with either of these with Surfing ?

Looking for recommendations.

Thanks in Advance.

Moment 2x Tele is usually the go-to lens.

Sirui also makes some HQ tele lens, they even have a 400x zoom lens but it would be very shaky and requires you to use a tripod.
