Laowa 12mm F2.8 Zero-D official lens correction profile now available

Starting from version 9.12 the free Adobe DNG Converter software now includes an official distortion and vignetting correction lens profile for this lens.

You can use it in RawTherapee or any LR version from 3 upwards.

A bit ironic, given that it has the moniker "Zero D[istortion]" Maybe it's an empty profile...

Even if there really is zero distortion (and I suspect there's a tiny amount), there will definitely be vignetting. The profile will correct for that

Went ahead and grabbed the file for the D-Dreamers: PENTAX (Venus Optics Laowa 12mm f2.8 Zero-D) - RAW

Yeah, it's also labeled the "D-Dreamer" haha

Especially at F2.8. It decreases rapidly though...


Had already processed this shot earlier this month when shot, but tried to process it again as similarly as possible with just adding the correction profile in RT. (Just the touch ups done afterward in Gimp might have been slightly different...)

K1, F2.8, ISO3200

Before


After


Edit: ok here's one slightly more scientific... F2.8 ISO3200 just processed in RT before and after the profile

Before:


After:
