Tamron lenses are generally beefy (heavy) lenses and the focus motors tend to be loud enough to be picked up in vlogs ( ive used many, Tamron zooms 15-30 2.8 G2 was the best but still picked up the purring motors )

F4 with the 10-18 is unfortunate for low light but still a great day time lens and zero motor sound.

The Sigma 16mm only downfall is no stabilization ( depending on your camera it shouldn't be an issue since vlogging isn't perfectly stabilized anyway ) but low light its amazing, its very very sharp, ZERO focus motor sound and very light weight.

Another option is the Rokinon 14mm 2.8 AF. Little pricey but great in low light. Unfortunately no stabilization either and a tab heavier than the 10-18mm f4 but again for vlogging, shakes are apart of that.

I've experimented with LOTS of vlogging style lenses and so far the Sigma 16mm 1.4 is my favorite budget and quality balanced.

The beast vlogging lens would be the Sigma 14mm Art lens
