Not the same as your experience but nobody if claiming Z9 or Z8 performance. The z9 and z8 are stacked sensors and are blackout free. The Zf sensor is the same sensor in a Z6ii, it’s BSI and does not process information as quickly.

If you read Thom Hogans review he says the same thing. Look under focusing, the first paragraph or two.

Everybody’s experience is different. Mine has not been perfect with occasional misses, but the difference is that I am okay with that for $2,000. Would not have been okay with that with the Z9.
