Which is better for travel?

The 16-300mm, because one lens covers landscapes, portraits and distant subjects. The 10-18mm is smaller and lighter but leaves you without reach.

Which is better for video and vlogging?

The 10-18mm. Its constant f/2.8, light weight and suppressed focus breathing suit gimbals and handheld wide shots. The 16-300mm is heavier and darker at the long end.

Only if you shoot both ultra-wide and distant subjects. The 16-300mm already reaches 16mm, so the 10-18mm mainly adds the wider 10-15mm view and the brighter f/2.8.

Which has better low-light performance?

The 10-18mm, at f/2.8 versus f/3.5-6.7. The 16-300mm offsets this partly with optical stabilization rated up to 6 stops.

Is the 16-300mm worth $35 more than the 10-18mm?

Yes if you want one lens for everything. At $694 versus $729 as of November 3, 2026, the 16-300mm covers far more focal range for less money, at the cost of weight and aperture speed.

Neither has a published shutter-style lifespan. The 16-300mm is the only one of the two listed as dust- and splash-resistant, which helps in bad weather.
