Originally posted by CDW I only have the 16-45 F4 available to test the lens correction feature. It seemed to not do a great job of it. I found that CA correction was still better performed in Light Room 3.4. Has anyone else had a similar experience?
Many Pentaxians do prefer to perform the lens distortion correction on computer.
Personally, I perform lens distortion correction with PDCU 4.32, unless I want more accuracy. In the latter case, I use PTLens. PTLens is an excellent dedicated software for lens distortion correction which is worthwhile for engineering and architecture.
PTLens is well regarded and can be recommended. The price is modest:

Hope that the comment and experience will assist.
