Dear K-x/ K-7 users.
Has anyone tested the distortion correction feature?
Any comments on whether it really works? Or is it better to do post image processing (e.g. using Photoshop, PTLens, etc)?

Yes, I read somewhere that the feature only works when you shoot with a DA or DFA lens.
Just wondering whether any of the K-x/K-7 users have actually tested this feature and can share on how well this feature works for you.
To be honest, I was rather surprise to see this feature available in K-x/K-7 as it is usually only available in more expensive camera. If it really works, it will save me a massive amount of time (i.e. instead of having to shoot in RAW mode and do post processing).
I've been using Nikon D40 for years, and experienced quite a fair bit of barrel distortion when using the kit lens (well, I suppose this problem is common for most of the zoom lenses out there?). Time to upgrade the gear and thought the "distortion correction" feature is one I will need when getting my new DSLR.

However if you do happen to have the new Adobe Photoshop CS5, one can have on-the-fly lens distortion correction based on presets of popular lenses from different camera makes. You can shoot in both jpeg or RAW and even create your own lens correction setting presets. Very quick timesaver during post processing, so it all depends where you want the corrections done.
distortion correction off at 18mm (kit lens): 0.8%
distortion correction on at 18mm (kit lens): 0.1%
distortion correction off at 55mm (kit lens): 0.2%
distortion correction on at 55mm (kit lens): non-existant

If you want an in-camera no-fuss approach to distortion correction, this is a good solution.
Hi airconvent,
since you are a K7 user, can I check with you whether it is possible to customise a hardware button to quickly enable/disable the distortion correction feature? or must you go into the menu to enable/disable it?
they have correction for the sigma 10-20? :lovegrin:
if that's so, i must get cs5 asap when i change computer. :lovegrin:
or maybe i should just get ptlens.. it's only usd25 after all...
Some latest info for you:
Adobe has posted a pre-release version of its Lens Profile Creator utility that enables creation of custom lens profiles for Photoshop CS5, ACR 6.1 and Lightroom 3. The process involves downloading and printing a checkerboard test chart from Adobe Labs, and shooting a series of RAW or non-RAW images. These can then be imported to the Lens Profile Creator to generate custom profiles for the Lens Correction feature in Photoshop CS5 and Lightroom 3. Furthermore, these profiles can also be shared via the company's user community.
