Sony G SELP1020G 10-20mm
Weighing just 179g and measuring 2.25 inches, this ultra-wide zoom maintains constant f/4 aperture across the 10-20mm range with fast linear AF and weather sealing. Three aspherical elements suppress astigmatism while the power zoom system reduces focus breathing for steady video capture. Best suited for travel vloggers and handheld run-and-gun shooters needing a lightweight, stabilized wide-angle on Sony APS-C bodies.
Snapshot
The 30-Second Version
A once-decent superzoom that has been left behind by sharper, more modern rivals. The 10x range is convenient, but softness at the long end and sluggish autofocus make it a hard sell against the Tamron 18-300mm or Nikon Z 28-400mm. Only worth a look if you find it for a bargain price.

vs Competition
The superzoom field has gotten crowded and seriously good. The Tamron 18-300mm f/3.5-6.3 for APS-C E-mount is sharper, focuses faster, and reaches further on the telephoto end while costing less. If you are on a full-frame Nikon Z body, the Z 28-400mm f/4-8 VR is in a different league optically, though it is pricier. Even the Sigma 16-300mm f/3.5-6.7 DC OS for crop-sensor shooters delivers better image quality across the shared range. The Sony 24-240mm's only remaining advantage is its full-frame coverage and used market availability, but that is not enough to keep it in the top five.

Who Should Skip This
Anyone who values sharpness at the long end or needs reliable autofocus for moving subjects. Video shooters will hate the loud, hunting AF motor. If you shoot on an APS-C Sony body, the Tamron 18-300mm is a flat-out better buy. Full-frame shooters should save up for the Nikon Z 28-400mm or a two-lens kit that will embarrass this lens on image quality.
Verdict
The Sony FE 24-240mm f/3.5-6.3 OSS once held a spot as a reasonable all-in-one travel lens, but the competition has sprinted past it. A 62 out of 100 is a tough score, and it reflects a lens that now feels dated and optically compromised. Newer superzooms from Tamron and Nikon offer sharper results and faster autofocus, often in lighter packages. Unless you find this lens at a steep discount on the used market, it is hard to recommend when the alternatives are this much better.
