I totally agree and unfortunatly we live the generation of lens chart "experts" who troll internet review re-gurgitating the same old twollop, without every understanding why or how to use a particular lens.
More like the age of the arrogant artistic/pro type who doesn't get tech and just tries to disparage those who do.
Learn how to expose!!!! Learn how to shoot!!!!
Yeah whatever. Of course nobody who cares about any lens or sensor details knows how to expose or cares to ever bother trying to compose.
It reminds me of the old mk 24-70L lens....widely slamed by review sites and yet it's in the lens bag of 99% of professionals who shoot Canon. It was the web based amatures who dissed it while most of the pros loved it and were perplexed by the amatures opinion.
It depends what you wanted to do with it and what type of pro you were. Plenty of pros don't shoot anything that needs crispy corners at 24mm FF or care about purple fringing branches against skies. Then again some do. It depends what you wanted/needed out of it.
I also see a ton of pros praising the new version and saying it was well worth the price over their old version.
Don't forget that the new one also has a higher precision AF engine (which most other than landscape pros could surely appreciate at least a little bit) and it's not just sharper across the board but also fights off stuff like longitudinal CA better. If you don't care, don't pay, but enough with the high and mighty act.
In my opinion many maligned lenses generally outperform their owners!
That's as silly a tired old statement as saying that only the lens matters.
Very few photographers actually need sharp corners wide open. Unfortunatly, twee lens review sites tell uninformed people that they do.
It depends, for super-tele and 70-200 longer lenses it can be nice to have sharp corners wide open.
It's not as critical for a wider lens in many cases, I think PZ was a bit off for slamming the 24 1.4 II as being worse than the 24-105 just because it has totally soft edges at 1.4 (nevermind they are much sharper at all shared apertures). That said, at times you might have important stuff off-center and many lenses quickly go bad off-center at f/1.4.
Also don't forget that this lens does a lot more than just offer better edges sharpness. It gets rid of halation which can occur across the frame when shooting say the canon 50 1.4 at 1.4 under bright conditions and when too much light is reflecting off everything in the scene. It can also get tons and tons of nasty purple fringing (and green haze over OOF stuff).
There are photographers who shoot only lens charts and like twiddling their moustaches....apparently they consider themselves "experts" although they often don't seem to have the matching photos
The funny thing is that so far from what I've seen, 80% of the people who write what you just did end up having nothing but some shots of a few cats in their back yard in their galleries and the amateur twiddler lab techies end up having giant galleries from around the world or big time sporting event, etc.
