What are the benefits/drawbacks of doing in-camera lens corrections vs. doing it on a computer as part of the post-processing? I guess that Pentax should be the ones to know their lenses best so they should be able to make the best corrections being in favor of doing it in-camera (or in Digital Camera Utility).

For me the main drawback is writing time. It you are taking lots of pictures you may have to wait for the camera to process all the files and save them. I turn them off.

Great question. I usually leave it on in camera.

Thanks,

If you want your photos in JPG format straight from the camera, that's what the in-camera corrections are really for. As far as I know, they have practically no effect on RAW files. So if you only shoot RAW, you may well turn the corrections off, so (as sergysergy said) they will not make the saving to card process slower. (The do have an effect on the JPG preview of the RAW file.) The DCU software probably has the same corrections (lens profies) as the camera, and also Adobe LR or Camera Raw have in the latest versions lens profiles to correct at least most of geometric distortions and vignetting for specific lenses.

The two problems that come to mind are:
-If you are using RAW files (like I) almost exclusively, in-camera lens corrections won't work (at least I don't believe they do with DNG files)
-My Digital Camera Utility software didn't run that well on my hardware so I switched to LR 5 (I haven't tried any updated version of Digital Camera Utility since, so this issue might has been resolved in the meantime though)

I shoot RAW+JPEG - if I am satisfied with the JPEG (which I most of the time am), I don't bother working on the RAW. I have the HD 11-18mm which, I guess, could benefit from some lens correction. I couldn't find an option for it in the camera settings so I guess it's not doable but can you have the camera only apply lens corrections to some lenses and not others? Except for changing the settings every time you switch lens.

I just leave them off and have them applied automatically when I import to the desktop.

If you have a lens (or lenses) that require a specific combination of corrections, you can dedicate one of your USER modes for that purpose.

The main decision you have to make is if you intend to use the jpg files the camera produces or if you intend to postprocess your picture. In case you decide to have your Camera do the postprocessing at the time you make the Shot, Pentax offers various options und settings which let you customize the look and feel of your pictures - options well worth your attention to tune the results to your liking. Lens correction is part of this options for this in-camera-processing.

The pro: it fixes flaws your lens might have. The con: it takes time - which doesn’t hurt if you don‘t take multiple pictures in a burst.
