The firmware update Ver. 3.10 from Ver. 3.00 incorporates the following issues:
1. Improvement of the flash function when "MECHANICAL+ELECTRONIC" is selected
An external non-TTL flash will fire when the "MECHANICAL+ELECTRONIC" is selected in the "SHUTTER TYPE" option of the SHOOTING MENU.
If "S (Shutter-Priority)" or "M (Manual Exposure)" mode is selected, set the shutter speed to 1/180 sec. or slower.

2. Improvement of the Wi-Fi function when "FUJIFILM PC AutoSave" is used
The phenomenon is fixed that Wi-Fi communication with "FUJIFILM PC AutoSave" stops at the moment the LCD turns off
3. Improvement of the display for the "USB MODE" in the SET-UP menu
1) When "PC SHOOT FIXED" is selected, the warning of "IMAGES ARE NOT SAVED IN THE CARD" appears
2) In case that "PC SHOOT FIXED" is selected in the "USB MODE" and the camera is not connected to a PC via a USB cable, you cannot turn off the camera when you turn the ON/OFF switch to the OFF positon or remove the lens from the camera becasue the camera stays in the waiting mode for image transfer.
With this upgrade, the message below will appear to confirm whether you stop the image transfer to the PC or not in such operations. If you press "OK" button, the camera will turn off without recording images.

有一只EF42 不知道I40 怎么样，还是忍忍继续等待富士的52指的新灯。。 本帖最后由 无人赏影 于 2015-4-1 11:04 编辑

不需要，拷贝升级文件包到sd卡，开机按住disp/back 键， 会显示升级镜头还是相机。我的xf14升级到3.1 和xt1升级到3.1

请教：升级时，是否需要装上闪光灯和卸下镜头？

没看懂！升级了！

很给力。出行前升级了。

希望也给XE2更新一下电子快门和高速同步

     这支灯我有SONY口的,色温感觉偏冷

我就是 i40呀

升级了，没有支持高速的闪光灯，用x20支持1/250秒了，有提高。

是用i40吗？

高速闪光同步呀，这个好

TTL  模式下，机械快门+电子快门，可以闪光了，1/4000秒，完全没有黑边，这个功能好。

纯电子快门，不能闪光，这个不给力。
