I remember you had problems with the 70-200 L classic, I showed in the past a sample from mine here
https://www.canonrumors.com/forum/t...meras-lenses-update.44469/page-2#post-1024667 shot wide open handheld 1/160s (so slightly below security shutter) @200mm and even at 800iso the focus plane was crisp, I was really lucky with that lens, and that's why I have it since almost 20 years, while the average lens stay in my bag is around 2/3yrs
YES, that! Looking back, perhaps I was a little optimistic. I don't think my copy of the lens was as sharp as I mentioned there

I don't miss it at all, I sold it almost three years ago, had the Tamron 70-200mm f/2.8 G2 for a year, and then I finally bought the RF 70-200mm f/2.8.
The Tamron had decent glass and autofocus, but the build quality was not on par with Sigma Art lenses. My copy of the lens was less than three years old, I bought it from an amateur, and the lens looked worse than my 50 Art that had over 5 years in the hands of a wedding photographer. At first I though it was due to poor handling from the previous owner, but then I realised it was the lens really, I'd rub my hands and its letterings would come off

Yes, that easily! Also, the matte finished plastics didn't age well.
Plus, the glass didn't have any "special rendering" like Sigma lenses do so, when comparing third party versus third party, the Tamron lens always felt a little lower grade. I used it for a year, sold it for 20€ less than I'd bought it for, and never looked back at Tamron.
For camera bodies, in fact, if you remember in the following paragraph I stated that the gimmicks on AF are surely the most important of the gimmicks
The thing is, I feel like the ratio of usable photos has increased massively with the mirrorless transition. Sure, glass is still more important, but now we're getting consistency levels that were unimaginable with DSLRs. You aim, you initiate focus, and you know you'll have something.
Not only that, but the ratio of photographs that are actually 100% in focus (not just "good enough to be usable") also increased significantly. How many of us used to stop down to have enough room to keep subjects in focus while recomposing or focusing continuously? Now we're tracking moving subjects continuously at f/1.2, f/1.4, f/2, and we still get files that are good enough for cropping, if we later decide to do so, because they're perfectly focused.
Also, now we're relying more on camera bodies for distortion corrections, we have stupidly high usable ISOs...
I think more credit goes to camera bodies now than it ever did in the past. These days, you may consider not buying the faster glass because you'll just crank up ISO in your camera and do the work that way.
