The following fixes and improvements have been incorporated.

1. It allows the latest lens names to be recorded in the Exif information of images taken.

The lens IDs of lenses released after the EOS30D are not in the camera; so these lens names could not be recorded in the Exif information of images. The Lens IDs for the following new lenses are now included, so that the correct lens names will be recorded in the Exif information of images.

• EF 14mm f/2.8L II USM *1)
• EF 50mm f/1.2L USM *2)
• EF 85mm f/1.2L II USM *2)
• EF 16-35mm f/2.8L II USM *1)
• EF-S 18-55mm f/3.5-5.6 (Not sold in Japan) *1)
• EF-S 18-55mm f/3.5-5.6 II (Not sold in Japan) *1)
• EF-S 18-55mm f/3.5-5.6 USM *1)
• EF-S 18-55mm f/3.5-5.6 II USM *1)
• EF-S 18-55mm f/3.5-5.6 IS *1)
• EF-S 55-250mm f/4-5.6 IS *1)

The correct lens names for the lenses marked *1) above will be recorded in the Exif information of images.
Lenses marked *2) are added if the firmware is version 1.0.5 or later.

2. Lenses that are compatible with the Digital Photo Professional 3.2 lens aberration correction function have been added.

More lenses will be supported by the lens aberration correction function of Digital Photo Professional 3.2, Canon's RAW image viewer/editing software.
Specifically, the ten lenses listed in item 1 above have been added. In images taken with these lenses and cameras updated to v1.0.6, the lens aberration correction function can be used.
For other supported lenses, see the user manual for DPP 3.2.

Are the previous versions of the firmware included in version 1.0.6?
