Fujifilm mkx 18 55mm t2 9 vs sigma 18 50mm f 2 8 dc dn contemporary?
The Sigma 18-50mm f/2.8 DC DN Contemporary is my pick for most people. It's autofocus, it's a constant f/2.8, and it's a tiny standard zoom that I'd call the best upgrade from a kit lens on APS-C. It also fits Sony E, Fujifilm X, L-Mount and Canon RF, so it's useful if you change systems later.
The Fujifilm MKX 18-55mm T2.9 is a different tool. It's a manual-focus cinema zoom with geared rings, rated T2.9, and it only mounts on Fujifilm X. If you shoot video with a follow-focus rig, it makes sense. For everyday stills, where you want autofocus and a faster aperture, I'd go with the Sigma.
Both are APS-C lenses and neither is stabilised. You can compare the full specs and frame equivalents on each page: Sigma 18-50mm f/2.8 DC DN Contemporary and Fujifilm MKX 18-55mm T2.9.
