Sony a7rIII rendering is awful

That other post is mostly about abrupt edges in what should be smooth out-of-focus background gradients, and Adobe has acknowledged they are working on a fix--to that issue.

This thread is at least talking about a yellow cast with some profiles. 

It seems to me that these are two different issues.  Perhaps Adobe will fix both by redoing the profiles, but perhaps not.  In many cases, they seem loathe to change color/tone rendering with a fix because it will invalidate anyone's work who has perfected their images using the old profiles.  Now if they make their coding smart enough to know what version of profile was used then maybe that is a solution.  Making a new v2 set of profiles would also mitigate the problem, but is overly cumbersome with such a new camera.

Yes, here is a test example, the ones of the Sony are all the same picture, shoot in RAW + JPEG, RAW developed in Lightroom and Capture One 11, no adjustments made, white balance is for all the same, Nikon D810 shoot slightly different angle and it seems whitebalance is a little bit different with the Nikon, but that's fine, skin tones are all very good expect of the Lightroom Camera Standard for Sony.

As you can see the "skin" color is for the 1., 3. and 4. picture are nearly the same and all fine for me, consistent results, only the Lightroom Camera Standard for Sony A7r III has a yellow cast (Picture 2) and that is my problem, never had such a problem with Lightroom with any other camera before, Camera Standard is normally the same as OOC JPEG and what is displayed on the camera rear LCD screen.

johnd60246340  wrote No, he doesn't have some other problem. Lightroom's ability to render Sony RAW files is notoriously awful and has been for a very long time. It has to do with how Lightroom can't read the built in "Sony creative styles" which Sony imbeds in their RAWS. Capture1 can along with Sony's IDC software. This has been a long thorn in the side for us Sony users and why Adobe doesn't do this is beyond me. Also, the sharpness is horrific. In Lightroom, details look muddy compared to other programs. There is currently no support inside Lightroom for "DRO" either which Sony's IDC and Capture both can decipher. I actually wrote about this a few years ago on my blog.

John,

I don't know why not being able to read these metadata tags makes raw rendering awful. Lightroom can't read these for ANY camera. Sony is not an exception. I never change these in camera (it's a giant pain to try and change these in camera and they don't affect the raw data anyway) and only switch them in the profile section in Lightroom. Using the camera profiles like shown by "just shoot me" above, out-of-the-box rendering is virtually identical to the in-camera rendering so the inability to read the metadata tag is rather inconsequential. Camera profiles are a strangely unknown feature of Lightroom. Just set your default for your camera to render using camera Standard and you're generally golden.

Can you show us a screen shot of the develop module with one of those images.

This sound more like you have a bad memory card, bad camera, bad cable from card reader or camera to computer or some other hardware malfunction.

I, personally, have not seen any other reports of the problem you are having.
