Curvi­lin­ear dis­tor­tion

Amateur Photographer - - Testbench Lens Test -

Our tests re­veal a slight hint of bar­rel dis­tor­tion, which is pretty typ­i­cal for a full-frame 50mm lens. In most sit­u­a­tions it’s not go­ing to be a prob­lem, un­less you’re shoot­ing highly geo­met­ric sub­jects and that de­mand lines along the edge of the frame should be per­fectly straight. But the sim­ple dis­tor­tion pat­tern means it’s easy to fix in post-pro­cess­ing.
