Fujifilm has issued new firmware updates for its X-T1 and X-T3 interchangeable lens cameras.

Firmware version 5.51 for the X-T1 renews compatibility with XC15-45mm f/3.5-5.6 OIS PZ lens, which has became incompatible when firmware version 5.50 was installed. It also adds compatibility with the Focus Preset Function and  Focus Control button for the XF200mm f/2 R LM OIS WR lens and compatibility with the  XF1.4X TC f/2 WR teleconverter, which is bundled with that lens to the XF80mm f/2.8 R LM OIS WR Macro, XF50-140mm f/2.8 R LM OIS WR and XF100-400mm f/4.5-5.6 R LM OIS WR lenses. It is available for downloading here.

Firmware version 1.02 for the X-T3 addresses three issues:
1. It fixes a phenomenon that occasionally prevented the buttons from being used while using histogram display or sports finder.
2. It also fixes another rare situation that prevented a RAW image from being recorded normally under certain conditions (Sports finder mode, continuous shooting with electronic shutter and so on).
3. The final fix corrects minor unspecified defects.
