Re: RF 100-400mm F5.6-8 Adobe PS/LR Lens Profile?

Wait for an update or create a profile yourself. If you are lucky Adobe releases it this month.

My RF 100-400mm F5.6-8 is due to arrive today, and I can't wait to try it out! I'm curious what people are doing about the lack of a lens profile for Raw processing in PS/LR? Is there a different lens profile that works for it? Or are you correcting manually with the Distortion, Defringe, and Vignetting sliders? Or is the lens good enough that no correction is needed?

I'd rather not mess around with DPP if at all possible.

Thanks for the help!

Bad news, as far as I have seen with other lenses, you can't expect profiles from the other companies for a month or two. From my personal experience, DxO is pretty quick with rolling out new profiles (maybe about one month from first shipping), and Adobe seems slower.

The others are using Lensfun (DxO and C1 don't use Lensfun). It takes 1 minute to take vignetting correction samples/focal length, so less than 10 minutes for 100-400.

Distortion correction samples could take some minutes. You just need to find the right place. CA correction could you just use the same pictures as for distortion correction.

After that distortion calibration in Hugin is what will take most of the time. In the video it took 5 minutes for a non zoom lens. For a zoom lens it will take 5 times longer. The reason why it takes time for the other companies is because they wait for users to do it.

There has been a lot of talk about RF16/2.8 STM and its distortion, but nobody has, what I have seen, taken a single picture of something that could be used to create a decent distortion correction profile from, like this picture.

What I found was a stone wall picture taken at close distance, so I created a distortion correction profile from that https://www.dpreview.com/forums/post/65570007?image=0

So now it is possible to use RF16/2.8 STM distortion correction profile in RawTherapee, ART, darktable, DigiKam, Topaz Studio, Photomatix, ON1, ACDSee, easyHDR, SILKYPIX and Affinity Photo.

If anyone wants better Lensfun distortion correction profile for RF16/2.8 STM, then take a correct raw sample.
