Sony FE 24mm f/2.8 G: Distortion and Distortion Correction

The Sony FE 24mm f/2.8 G has considerable barrel distortion, perhaps around 6%. Correcting it is all but essential, but that is not a single-checkbox task, but a manual process involving correcting, scaling, cropping.

Correcting the pronounced barrel distortion would be a single checkbox if Adobe Camera Raw had an appropriate lens profile. But it has only a “built-in” profile for chromatic aberration. Since there exists no listed profile for the 24/2.8G, no profile with built-in distortion correction can be chosen (that is the correct match). So it becomes a manual correction.

This page shows the distortion and the step-by-step instructions on how to correct it:

Sony FE 24mm f/2.8 G: Distortion and Distortion Correction

UPDATE: I’ve simplified the steps for distortion correction of the 24/2.8G. An update to Adobe Camera Raw could include a lens profile that allows selecting the lens and using a built-in distortion correction so that the current manual correction is not needed.

It’s disappointing to see a lens like this rely on distortion correction. Yeah, Nikon does it and so does Fujifilm. But at least with them it is flagged as required and taken care of automagically. Sony really needs to get with Adobe and fix this lens profile mess.

Worse, my results are showing major losses of sharpness particularly in the outer zones. Because the distortion is really extreme and that requires a ton of cropping and correction.
