Which is better for travel?

The 16-300mm covers far more scenes with one lens, from wide streets to distant wildlife. The 18-50mm is lighter and better in low light but leaves you without reach.

Which is better in low light?

The 18-50mm f/2.8. Its constant f/2.8 lets in roughly two stops more light than the 16-300mm at 50mm, where that lens is around f/5.6-6.3.

Which has better image stabilization?

The 16-300mm, which has built-in optical stabilization rated 6 stops at the wide end and 4.5 stops at telephoto. The 18-50mm has none and relies on the camera body.

Is the 16-300mm worth $195 more?

Only if you need the reach and macro. At $694.00 at Adorama versus $499.00 at Focus Camera as of November 3, 2026, the extra buys range, stabilization and sealing, not a brighter aperture.

The 18-50mm f/2.8 is generally the sharper lens, especially at the edges and wide open. The 16-300mm is a superzoom and gives up some edge sharpness for its range.

Can I use both on the same camera?

Yes. Both are Sony E-mount APS-C lenses, so they fit the same bodies. Many owners pair the 18-50mm for everyday use with the 16-300mm for travel and wildlife.
