Hello pw-pix, Thanks for your response, Actually, I mentioned testing on street because you can easily detect it when testing on street. But in fact only testing with small group of peope, even with couple, this issue also happen quite frequently.

Do you have a film simulation in use for jpg? Does it have a Clarity setting? Any clarity setting other than 0 is know to cause processing/write delays when shooting jpg.

Don't use eye tracking for street. Just use a small area or single point.

Yes, they are available both in camera and in Lightroom. The issue arises when I then open the image in Photoshop, where the sim isn't applied. I haven't tried every film sim to see which ones are carried over into Photoshop, but the two mentioned definitely do not.

Yeah, IS is on with in countinuous mode.  It used to work for me too, but yeah, it doesn't anymore.
