Review on 📷 VILTROX 23mm Fuji F1.4 New Version: Auto Focus APS-C Lens for Fujifilm X-Mount Camera X-Pro 3 & X-Pro 2 by Jon Lewis

I bought this about two months ago and use it with the X-T4 body from time to time. Photography-wise, everything works fine when I'm taking a single shot or using AF-S mode. Things get a little worse when we switch to AF-C mode or movie recording. It pulses, flutters or "breathes" like crazy - it shows a green border around the subject - but the background keeps getting sharp and blurry - I've tried this at 1.4 -> 2.8 and it seems to his same behavior. visible. If the subject remains VERY still, then (sometimes) everything seems fine. This is especially evident when there is something very legible in the scene as it goes from nicely out of focus to heavily in focus. For reference, I tried this with firmware 1.0.9. It comes with newer firmware 1.1.2 which is available for download on their website.
