When I switched to full sensor camera I started experiencing problems with chromatic aberrations more often than before. I only use Lightroom 2.5 for my post processing so I looked at its lens correction module and it seems like it will be very hard to automate it in y workflow. I started looking for some solutions. Of course if you have full version of PhotoShop you can create action and then use it in LR but I would prefer something cheaper than this. I found great tool called PTLens. Unfortunately there is no plug-in for LR so I started looking for it and found none. I downloaded Adobe Lightroom SDK and decided that learning Lua programming language is probably not so hard. It took two evenings to right something that works. I got post processing filter that calls PTlens after exporting each photo. It's good enough for me but I wonted make it more like Photomatix plug-n so you can select image and edit it interactively in PTLens. 

If interested you can watch progress on Google Code: ptlens-lightroom-plugin. When it's ready I will publish it to Adobe Exchange.
