Questionable, but good on Sony A7R III

So I have this mind boggling - should I buy FE 12-24 to replace 17L TS-E? I already owned FE 16-35 GM. If it's an effective substitute I don't want to lug a bulky manual-focus lens, although MF is very easy via EVF. What's your opinion? The member 'Joger' used to passionate on 17L TS-E now advocate FE 12-24G all the time Both FE 12-24 G and FE 16-35 GM are great lenses, I picked up later on my priority - f2.8, slight sharper and dislike severe stretching from 12mm. It's impossible or very hard to level the camera in most scenes.

I have Sigma 12-24 which is nothing to compare to Sony 12-24G in therms of sharpness. I wish I had this new Sony 12-24G for side-by-side comparison with Canon 17TS-E. For example with shifted Canon 17TS-E I'm stuck with f11-f16 all the time, I guess with Sony lens f4, f5.6 apertures are quite usable.

Oh, realized you have Sigma version. Agreed FE 12-24G is fanatic that is well reviewed by all and it's compact and light. Also I don't know why you must stop that much? I personally don't care a little soft at far edges after full shifted that usually only happen in very close subject that shown up in far corner after shifted up. After full shift the focus axis has been dramatically moved so this is expected.

In my opinion any regular UWA lens can't substitute a Shift lens just because it doesn't allow us to see final photo composition - after post-perspective correction we will loose some edge area, which may likely ruin the original photo.

That actually is not my top concern but fully agreed. From you samples, the perspective between UWA vertical fixed vs 17L TS-E shifted-up are different that latter seems amplified and subject looks closer and bigger. Guess on individual taste.

In this terms, I wish Sony (or all the brands) implement on-the-fly perspective correction based on built in spirit level. Just like Sony has PictureStyles to display in BW on-the-fly, do the same for geometry correction. With such functionality I could shoot architecture with ANY lens, making sure the final (perspective-corrected) composition is what I have pictured.

Great ideal that can be done actually, in-camera correction as Sony at least did anyway on its UWA lenses such as FE 12-24.

As for the ease of MF with Sony EVF. Absolutely agree, I couldn't imagine focusing with regular optical viewfinder (I have my old Canon 5D). Focusing with Sony's hi-res, zoom-able EVF is pleasure.

Once I (and many others) used to EVF cannot go back to small, dim and lack of info OVF. Today's EVF is a complete different story than a few years ago - big, bright (that can be adjusted), no flicking, virtually no lagging (especially A9's), full of info and tools (zebra and peaking) and AF/AE are very accurate in LV.

BUT
Auto focusing with Sony 12-24G is even easier

of course.

BTW, this new zoom lens seems even wider MF however which is not a big in such wide lens. Sunstars seems beautiful that in general a weakness (and strength in Canon) in Sony lenses. If it's sharp enough I might buy this one instead of FE 12-24 that will have many fun photos from it, I guess.
