Adobe Lightroom 6.13 'Lens correction profile' needed for e-mount 18-135mm f3.5-5.6 OSS

Do any of the learned members of this forum have an idea of how I can locate for download an Adobe Lightroom 6.13 'Lens correction profile' needed for my new e-mount 18-135mm f3.5-5.6 OSS?

 

Adobe has already announced the availability of the profile just this month to be incorporated into future updates to the Abobe Creative Cloud Lightroom versions - however those of us with the genuine but 'standalone' version of Lightroom were told that support (apparently including this sort of update) was to be withdrawn at the end of 2017...

 

I would appreciate any thoughts. I am temporarily using the existing 18-110mm f4 e-mount profile which works but is not "optimised".

Re the Lightroom lens profile. Interestingly, there are A-Mount lens profiles already available in Lightroom, including an 18-135mm which, in use in LR looks excellent. I suspect that, ignoring the mount, this is very close to the E-mount lens profile required. Glowinthedark asks how to create a zoom lens profile from scratch (which I can not answer) but I would just add "look for the profile for a similar type lens and you won't be far off" - at least it should be a good starting point.

I guess you will have to repeat these steps for different focal lengths. For the software PTLens e.g. it is necessary to provide 5-10 different focal lengths over the whole zoom coverage to enable the programer to create a profile. I guess there is some interpolation needed. But how that looks like, I have no glue at all...

I wouldn't use correction profiles for other lenses, especially not zooms. These tend to vary a lot.

 

In reality, it's quick and easy to make manual corrections. Sometimes it's even necessary because the LR profiles don't fully reduce all the visible defects like CA, distortion or vignetting.
