I can't say now how it worked in firmware 4.20 because I already "upgraded" to 4.21, but regarding this "Instant AF Setting in manual focus" issue, independently of what one sets in AE/AF-LOCK MODE menu item ("AE&AF ON WHEN PRESSING" or "AE&AF ON/OFF SWITCH"), it works in the same way, locking only when pressing, and unlocking after releasing the AF-L button, as if this menu item was ever in "AE&AF ON WHEN PRESSING". At least mine is working in this way now.

Very nice! Thanks!

If the lens don't have a clutch mecanism, setting the "M" mode (manual focus mode) in the X-T1 allows the use of the AF-L button to automatically focus (instant AF) AND lock the focus, but you still can use the focus ring to change the focus manually. It is more a way to instant AF in manual focus mode than to "lock" the focus. If the lens have a clutch mecanism, this procedure only works if the clutch mecanism is set in the AF position (the camera always in "M" mode); in this case, we only can focus using the AF-L button, and this is a very effective way of locking the focus because the focus ring can't move and the shutter don't focus in "M" mode. Hope this helps!

Funny that this did not happen with me. Anyway, the MD5 hash of the 4.20 firmware upgrade file is B4B40D14D358861F3DDE359433A69E8D. This can be verified on online sites as http://onlinemd5.com/

Here the link to the explanations X-T1/X-T1 Graphite Silver Edition New Features Guide[Ver.4.20](PDF : 764KB) Let me say first I am very grateful with all these firmware updates for my X-T1. But I confess it is a challenge to absorb all the information about AF, MF, clutch, AF+MF, FOCUS ASSIST, AF-L and so on. But I am in good company: I mean, the Fuji employees that wrote this upgrade manual, as there are minor errors on it. On page EN-1, on the second column (Section), at No.16 it should be written "AF+MF operation with AF-L button" and not "AM+MF Focus Zoom", which should be written at No.17, and they can abandon that "Checking Focus" text. Just trying to lessen a bit the entropy. Hope Fuji can correct this in a new version or even sort out a whole corrected and updated manual. Dreaming is free! Edited: I don't know what I did that I came to delete the original milandro post reference, from yesterday, 09:13 AM. Sorry about this!

If so, how can the led light goes instantly off shutting off the camera when "High Performance" is set to OFF? Strange fact. But for me, I think we already said a lot about it: enough said. Cheers!

You mean, to be a feature it needs to damage? After all, it remains lit only when you set "High Performance" ON. Well, I stiil think it is a feature or a bug, damaging or not. But I respect your opinion and I thank you for let me know it.

Indeed, very true. At this point only Fuji knows if it is a "feature" or a bug. If it is a feature, I couldn't care less. If it is a bug, I think is nice that fuji knows and fixes it. That's all. I continue loving and using my X-T1 as always!

Thanks for the information. The problem is that if "High Performance" is OFF, the IR light turns off at the same time the camera does.

Well, in this case, I think 5 minutes was good enough for "high performance", don't you think?

Thanks for answer, but I already saw, we just need a dark ambient (look my older posts in this topic, please). Well, when I loose measured the time it remains lite (20 minutes) the camera remained resting alone, nothing near it. I really don't know if this time varies with something, or it is always the same.

You're welcome!

This is what I found with the 23mm lens: Lens set to manual focus (focus ring turning): Switch on camera set to "M": Focus ring: focuses Shutter release: DOF preview AF-L: no effect AE-L: exposure lock Switch on camera set to "C": Focus ring: focuses Shutter release: DOF preview AF-L: no effect AE-L: exposure lock Switch on camera set to "S": Focus ring: if AF+MF is ON, shutter release focuses *AND* focus can be adjusted manually by rotating the focus ring while the shutter button is pressed halfway; if AM+MF is OFF, focus ring focuses and shutter release don't focuses. AF-L: if AM+MF is ON, focus lock; if AM+MF is OFF, no effect AE-L: exposure lock Lens set to auto focus (focus ring not turning): Switch set to "M": Shutter release: DOF preview only AF-L: focuses, don't lock AE-L: exposure lock Switch set to "C": Shutter release: focuses, but with continuous "hunting" AF-L: focuses, focus lock AE-L: exposure lock Switch set to "S": Shutter release: focuses -- no "hunting" AF-L: focuses, focus lock AE-L: exposure lock Some settings I was using during this test: Autofucus Stting -> Instant AF Setting: AF-S ...-> AF Mode: Single Point ...-> Face Detection: OFF ...-> Pre-AF: OFF AE/AF-Lock Mode: S (AE & AF ON/OFF Switch) AF-Lock Mode: AF-L (AF Lock Only) Shutter Type: MS (Mechanical Shutter) Interlock Spot AE & Focus Area: ON I hope this helps.

Well, we know that, at least, sporadically Fuji reads Fuji Rumors: http://www.fujirumors.com/i-have-the-proof-fujifilm-reads-fujirumors-every-day-and-confirms-x-e2-fw-in-octnov-x-t1-4-0-on-june-22/ With a little luck, they will read here too! Maybe it is a good idea Patrick (FR) gather the (eventually) discovered bugs and make them more visible. Thanks for the suggestion but I have neither Facebook nor Twitter.

Nice hearing you! I made some loose measuments and the IR light remains lit about 20 minutes after turning the camera off (High performance ON). Well, maybe it is not even impacting in a sensible way the battery, but it looks like a BUG, and if it IS a bug, it is always desirable that Fuji fixes all discovered bugs. Maybe this is not a big deal, just a tiny bug, but I think Fuji will like to know and fix it. Cheers.

Thanks for sharing. I was curious so I did the same tests but I didn't agree with your 4th observation: in all the tests, when "High performance" was on, the IR light remained ON for more than five minutes. Eventually it went OFF, but I was no more observing it, so I don't know the total time it stayed on. Also I observed differently from your 6th observation: even with sensor cleaning turned off the IR light remained ON for more than 5 minutes. Hey Patrick!!! Hello FUJI!!! I think we can call this a BUG in the firmware!

Thanks for the reply, Trenton. I'll give it a try tonight. Just curious...

Funny...! I can't replicate this on my X-T1... No sign of red glow coming from the eye sensor when switching off the camera when using the "High performance" mode. Wondering why...

Have you tried putting "Face detection" in OFF? Mine worked in this way.
