Can you explain what you mean by 'slowing the camera down?' Thanks.
There is time lack when reviewing an image and also when going back from playback to shooting mode. Very noticeable compared to, say, the 23f2.
So that only really affects someone who is chimping frequently. I don't so it doesn't bother me.
Good for you. But given the AF-S focus inconsistencies Fuji cameras show with lenses 23mm and wider, I rather check focus was where it should be.

Sigh, are you still quoting that ? Thought we sorted that out earlier.

IMHO the issue is your perception of where the problem lies. See:

Can you dwell on that a little? I don't know really what you mean. There is inconsistent focus and focus beyond infinity. How's that an issue of perception?

Did you read the item I linked?
I see no problem with actual af-s accuracy with my 14mm, or the 18-55 at 18mm. The issue is with the in viewfinder focus scale, which is pretty useless with those focal lengths, readings seemingly random and unreliable. I do not find any problems with actual focus achieved on the photos.
I will not debate this further with you, if af-s was actually so unreliable with wide angles there would be reports of it everywhere, in reviews and forums. There are not, you appear to be 'out of step with the army'.

There are so many reports all over the fora, and it is well known that Fuji AF is not up to par with other brands.

I stopped (with the obvious exception of this reply) having this debate with him months ago. Ths one-man obsessive crusade has been going on now for a few years, IIRC. As you point out, if this was the sort of issue that he implies, there would be widespread reports (in forums, on social media, in youtube videos) about it.

There aren’t.

At this point, I think that the best response is generally no response at all.

Simple one shot af-s performance has been OK for about 30 years. Such a fundamental issue would be the damnation of a system. My experience I did the link to is neatly 10 years ago, I've used the Xpro2 and other Fujis ever since with no problems. It's my normal practice, I don't have a need for af-c etc more than occasional. But no problems.

It is not okay. it returns inconssitent results with WA lenses, and more so stopped down, and it focuses beyond infinity. Easy to test, easy to reproduce. In particular focus beyond infinity is easy to spot. Overall slight softness when zooming in with nothing in critically sharp focus.

Wonder why you and Dan feel the need to defend Fuji AF no matter what. If you were really convinced that all was fine with Fuji AF, you'd just ignore me. But no. :-) Same with the 23f2.8 slowing the camera down: Jerk reaction is defend Fuji.

I have a pretty sizable Fuji collection and love using my cameras. But I do point to short comings. At the price Fuji is selling their gear now, I expect them to fix issues.

Well, my Fuji 23mm f/2.8 is maybe a tick slower, but it isn't more than 1/4 of a sec slower. Slower, yeah.

And maybe, it is best to state that Fuji AF is "poorest" of most all major brands, and I'd tend to agree it is less sticky and slower than Nikons and Olympus/OM from experience, but doing so over and over and over int he same thread is probably what gets people fired up.

You said the 23mm was slow, you said their AF is bad, multiple times, we get it. And you have a sizable collection, so... you tolerate it. Same here. People shouldn't be defending at every turn, nor bashing at ever one either.

It is worth talking about it until Fuji finally takes action. But of course, one could also ask the question "Which lenses to take to ..." for the umpteenth time :-)

Another good reason to keep this on the radar screen is to make sure folks know how to avoid the issue by using well know and much discussed workarounds.

And for those allergic to the topic (or so much in love with Fuji that any criticism hurts): Just skip my poss and don't read them. Me, I don't mind being put on ignore.

As to the 23f2.8: Not sure if it is 1/4 of a second. But there is an annoying delay when going into and out of review mode. That's all. It should be fixed by Fuji. Same with the strange focus aid behavior where the X-E5 zooms in but not out when half pressing the shutter button. But that is a different topic.

I found that changing the Clarity setting from 3 to 0 on the X-E5 eliminated the blackout after shutter release. I don't know if that's germane to this issue, though.

That is a separate issue not related to the X-E5 or the 23f2.8. All Fuji cameras that offer Clarity have a delay while the camera processes the setting.

I said i hadn't noticed it, not that I noticed it and forgave Fuji. You have put a different spin on my post. These things matter because inexperienced people may read these posts and think it is a major problem. Most of us are experienced photographers and telling you we don't think it is an issue.

Fortunately, none of my Fuji cameras or lenses (and I have owned almost every one of them over the years) have ever exhibited this behaviour.

Your Fuji images in your flickr gallery were mostly taken with tele zoom lenses. Focal lengths above 23mm don't show the issue as much as wide angle lenses. In fact, I am using my 35f2,50f2 and 90f2 with confidence in AF-S.

The MAJOR Fuji forum, where there is intelligent and often critical debate, has not a single mention of af-s accuracy issues with wide angles, in more than 10 years I have frequented it.
It comes up regularly here because you drag it into threads frequently. I don't recall eall others agreeing.
