Panasonic has announced the immediately available of a free firmware 1.12 upgrade for the new AU-EVA1 5.7K handheld cinema camera. This upgrade expands lens compatibility for a number of popular Sigma ART lenses.
Additional Sigma ART lenses supported include:
12-24 F4 DG HSM
24-70 F2.8 DG OS HSM
14mm F1.8 DG HSM
30mm F1.4 DC HSM
85mm F1.4 DG HSM
135MM F1.8 DG HSM
Along with the addition of these six lenses, a lens interface issue that caused the iris or zoom readout to display incorrectly has been resolved. The EVA1 utilizes an EF lens mount with electronic communication for iris, focus, zoom, image stabilization and other functions. There are many lenses from multiple manufacturers supported by the EVA1.
