In my experience it is very inconvenient to have to apply a profile manually for a number of focal lengths: you'd have to record the focal length while shooting and add it to the raw file manually and then apply the appropriate profile for that focal length. Especially geometric distortion varies a lot across the zoom range, so much so that one profile for a zoom lens will not work.
When the raw file is provided with EXIF data, a custom made profile can be applied automatically, provided a profile is made consisting of corrections for a number of focal lengths of the zoom range. I've done this a number of times with excellent results.
For a prime lens it becomes a lot easier: you only have to add the EXIF data to the raw file later in order to have the profile correct for geometrical distortion. Easy enough if you use one legacy lens among other more intelligent lenses. If you also want to correct for vignetting, you'd have to record the aperture as well during shooting; I do that by assigning a rating to the file, e.g. 0 for wide-open, 1 for 1 stop closed etc. Works well enough, but still requires attention during shooting.
Anyway, these days I lose interest immediately when a new lens without EXIF data transmission is offered; there are enough alternatives at present that present data in the EXIF.
However plenty of alternatives ? What are the other sharp, 500g, US$600, 12-24mm lenses I've missed ? I'll happily give up the EXIF for that and apply any edits required on a case by case basis.
Perfectly valid, everyone is going to have a different tolerance to just about everything related to lens selection. One big knock for one person may be a small price to play for another person.
I would definitely have to put some thought into it....but that's only based on my personal preferences. I didn't mean to imply it should/would apply to everyone.

I see where you guys are coming from regarding the issues in post. The only reason I hold on to my smart Nikon adapter is for my two zooms (28-105D and 80-200/2.8D) because they're broad-range zooms with very different distortion profiles necessary depending on where in the range I'm shooting. I wouldn't want to have to make notes for every shot taken, or change IBIS settings manually for those ranges, so I'm glad to have the EXIF information and the great profiles already in LR.
My feelings on this one are different. I'm confident I can set IBIS for 18mm and that will be close enough to cover the entire range (it'll only be three axis, after all). I am waiting on Bastian's review because I know he'll test distortion properly, with a building instead of a test chart, to confirm the relatively low distortion in my critical range. Assuming that holds up, then, like Kevin, I'll happily correct on an image-by-image basis when necessary. To me, some lenses are worth the extra effort, and a relatively small UWA zoom that takes standard filters and is more than reasonably priced is certainly one of those lenses.

That there wraps up this zoom in a few words. If light weight and standard filters and reasonable price are not criteria then there are other lens that are most likely better for you.
I'm also waiting for the review to understand how involved the post processing will be. I value small size and light weight — price and "standard" filters not as much — and also ease of use. That said, I don't really find I often need wider than my 14GM so I'm probably not in the market.

True. I should've also added manual focus with a proper distance scale to that list, which are key to me. If this were the typical focus-by-wire mirrorless implementation, it would not have my interest.

I should add that having the very impressive Laowa 12mm zero distortion already I'm hoping some of that tech has found its way into this zoom. There's obvious no EXIF / Profile for that lens either and TBH I hardly ever even bother correcting the minimal distortion (in many cases I actually deliberately use it). Obviously not for landscapes/cityscapes for which I choose other lenses.
So this is a slightly different case use (as it would be for landscapes/cityscapes) so we'll have to see how the testing goes. I may have to pop down to the mall to get one next week to try it out

I feel the same way about the DSLR 14/4. The minor barrel distortion and fairly even across the frame performance makes it pleasure to use both on digital and film. Plus it allowed me to adjust the focus ring to calibrate the hyper-focus marks perfectly on my slightly short F-to-E adapter, so shooting with it is a breeze.
Let us know how it goes if you do get your hands on one.
I currently have the Sony 12-24GM, but Im considering this. I usually manual focus with the Sony 12-24, and I like the results I get from the 10-18 Laowa, so this might be a great second wide angle option.
I’ve got the Laowa 10-18 and it’s ok, I wanted to use it for IR-Chrome but it didn’t work very well due to the filter being very thick. I was interested in this lens but it’s just been so long at this point. Also a lot bigger than I was expecting

Not in the same class. I had that 10-18 and it was a lot of fun but the edges were truly awful and distortion high. Laowa have improved dramatically since then.

I am still waiting for a final confirmation of the price.
Full resolution samples you can already have a look at, focal length should be noted in the tags: Flickr Album Laowa 12-24mm 5.6
Thank for image sample. It's look great. It's sharp from center through to the corner.
I already sold my 12-24 GM because weight and size of the lens and 170mm filter set. This lens might be the one i waiting for.

Awesome ! The price over here (in China), where the lens has been on sale for a few weeks, is 3.980 RMB (ca. US$594, £494 or €585). That is a firm price, all shops are selling it at the same price.
