XF 90mm vs XF 40-150 autofocus speed

Just got viltron 75mm f1.2 and also have 90mm f2 and 40-150 f2.8

I mainly use this focal length to big subject still isolated from background or for fast action like dog running around

I will keep for sure the Viltrox and Fuji 40-150 f2.8 it is much more versatile than a fixed focal

I was wondering if I do have any reason to also keep the 90mm and the only one I can think off it is if AF it is definitely faster that 40-150 f2.8

Viltrox 75mm f1.2

50-140, not 40-150

It depends on your needs. I have prefered keep the 90f2 instead of the 50-140f2.8. I use it mainly for portraits and I don't need long focal. And with the crop 1,4x of the X-T5, the 90f2 become a 126 with a 20MP picture. Enough for me.

That's only one sample from the 75mm yet I don't see the magical charm of the 90mm f2 in the image.

Yes no magic here, but I guess that with any lenses there won't be any magic on this image.

Ok it isn’t a good photo, I was just testing how much viltrox 75mm would separate the subject from the background but it is not really relevant with my question
