AF Operation Is Not Shutter Lag
AF Operation Is Not Shutter Lag
Am I missing something?
If you shut off the auto focus, isn't manual as fast as a Leica?
I may be wrong, but I definitely don't "sense" any shutter lag in manual mode on any of the x series cameras.

Tom,
You are right.
With an analog RF you turn the lens focus color to pre-focus via the focus scale or you focus by aligning the RF patch. When you press the shutter the delay is only involves the shutter mechanism operation.
With the XP1 you can pre-focus when you are using an adapted lens or a Fujinon lens with the in-camera digital focus-scale display. Again the lag is purely a function of the shutter mechanism operation. In my experience this lag is no longer than any other focal-plane shutter mechanism. In other words, the delay is not a disadvantage or noticeably slower than hundreds of other cameras
If the Fuji AF is set to M mode, and you press the AFL/AFE button to focus you are using AF manually. Once focus locks, the focus can not change unless you turn the lens collar or press the AFL/AFE button again. The same goes for just turning the lens collar without using the AFL/AFE button. With the latest firmware the focus-by-wire delay is reasonable (but this has nothing to do with shutter delay). If you switch back to OVF mode by pressing the control wheel, when you press the shutter there is no delay before the shutter operation begins. If you remain in EVF mode then there is EVF display delay.
In AFS mode a shutter-button half-press initiates focusing. If the button is fully pressed from the half-way position there is no additional delay. If the shutter button is released and then pressed again in a single full press, there is a focus delay which could be mis-interpreted as a shutter delay.
If you shoot in raw mode and bracket exposures, or use exposure burst mode, then there is a delay until you can use the shutter again cause by data transfer. Some menu parameters increase focus lag. If you choose to inhibit shutter operation until focus lock is made, the shutter delay can appear to be quite long. Of course this is really focus delay.
The above only applies to OVF mode. In EVF mode there is always an additional delay due to the time it takes to render the image and display it in the EVF. The XP1 does not have the fastest EVF display currently available.
An all-electronic shutter could have even less delay and be silent. But I don't think it would reduce EVF lag.
