The Sony 50mm f/1.8 OSS (model SEL50F18) is at number 3 in this guide. It is a prime lens for Sony E-mount APS-C bodies, sold at £239.00 and rated 4.6 from 2,379 ratings. On paper it is the steady one: the bullet list names Optical SteadyShot, and the spec table's Image Stabilization Type row says Optical, so the two agree with each other. That matters in this guide, because the cheaper 50mm f/1.8 for the same mount claims optical stabilisation in its specs that its own bullet list never mentions. The £239 is the one where the claim is repeated everywhere.

Its own table is not spotless. The lens is listed as a Prime with a Fixed Focal Length of 50 Millimetres, and both Maximum Focal Length and Minimum Focal Length in the same table read 50 Millimeters. Then the Zoom Ratio row gives 1:1. A lens whose focal length cannot move by a millimetre has been handed a zoom ratio. The wider listing does hold together elsewhere: the angle of view appears as 32 ° in the bullet list and as 32 Degrees in the spec table, and the diaphragm blade count matches at 7. Everything on this page comes from the Amazon listing as written, not from any test we have run.
