    Firmware Version 1.1.0 is for cameras with firmware up to Version 1.0.9.

(The following is the history of past firmware updates) Q: Are the improvements from previous firmware versions included in Firmware Version 1.1.0? A: Yes, the following improvements from the previous version are included: (Previous) Version 1.0.9

    improvements

    1. Fixes a phenomenon in which tone jumps become noticeable in some images, depending on the shooting scene, when shooting with the Auto Lighting Optimizer settings (Low/Standard/Strong). (Previous) Version 1.0.8 improvements:
    2. Fixes a phenomenon in which the set aperture moves unexpectedly when shooting movies in manual exposure mode using some Canon lenses (such as macro lenses). Supplemental Information: This phenomenon involves the aperture of the lens moving unexpectedly when the focusing ring moves (during focusing). Please note that aperture values also change when operating the zoom ring of a zoom lens that has variable maximum aperture values; however, this is a normal operation because the camera controls aperture values properly depending on the focal length (zoom position).
