>>3704428Kinda yes, Tamron software does give a bit more like speed tuning if you want to do video-focused stuff and make smooth transitions, or calibrate stuff so it goes quick as fuck in certain distances like 1m to 5m for street meme snaps.
But if your lens is "bad" that calibration is basically mandatory, so instead of changing it the company either sends you a complementary lens hub (the thing you need to connect it to the PC) or sends you a jewtube video on how to fix it. Sigma does get bad rap about it but they made their software cooler in recent times.
DSLR calibration afaik is because not all lenses/sensors are the same and you have to calibrate them and save as presets so they squeeze the most out of the resolution. Often protogs have to do this with every lens, it can fix backfocus issues at times, the Nikon D850 had shitton of problems with that until a firmware fixed it but it made everyone re-calibrate their shit.
Supposedly mirrorless skips all of this shit and magically fix them in-camera but i don't know about that, if anything the zebras/peaking simply pass the problem to the operator, for old stuff with no firmware updates/one-in-a-batch tier lenses with problems there seems to be no solution, i could be wrong there. It's a 35+ megapixel problem mostly.
