Firmware 1.12 on XC 16-50 OIS II

[itchy shutter finger]

Heads up if you download and update the 1.12 firmware update to your XC 16-50 OIS II lens.

The download is not the firmware .DAT file that you normally copy directly to memory card for the update process. The file you download is a .ZIP file containing a sub-folder which in turn contains two .DAT files. The files are named XFUP0022.DAT and XFUP0030.DAT. XFUP0030.DAT is the one that works. Copy that file to your memory card and proceed per Fujifilm's instructions.   

I updated three lenses: XF 18-55, XC 16-50 OIS II, and XC 50-230 OIS II. I didn't see any difference in the XF 18-55. The XC 16-50 seems to focus faster and quieter at distance; it hiccups to focus up close, which it always did. The XC 50-230 continues to impress me as my favorite lens for every reason you can name. After the firmware update, it seems faster and quieter to focus.

This could be my imagination too, since Fujifilm says these are minor bug fixes. In any event, at least two of the three lenses I updated give me the perception of improved performance. Thank you, Fujifilm.
