Canon EF-S 55-250 IS STM Firmware v.1.0.3 Available
Technically speaking, a new firmware for the Canon EF-S 55-250 IS STM appeard on Canon USA's website back in July (but we missed it). However, the firmware udpate may be more relevant than ever for the large number of people who likely took advantage of the crazy Black Friday refurb. deal on the lens (I'm included in that group). Then again, this updated firmware update seems to only improve AF performance when the lens is used with the EOS M3 via adapter.[Sean]
