Canon has released new firmware for the Canon EOS R5 Mark II. In addi­tion to a few bug fix­es, the main new fea­tures include a pass­word pro­tec­tion for the net­work set­tings, an option to chose the num­ber of images to be saved in advance in pre con­tin­ious shoot­ing and the future pos­si­bil­i­ty of car­ry­ing out firmware updates direct­ly in cam­era via a net­work con­nec­tion. Here are the exten­sive new fea­tures in detail:

1. Improved secu­ri­ty fea­tures. A pass­word must be set ini­tial­ly.
   •Adds the abil­i­ty to review the his­to­ry of any changes made to the pass­word, net­work infor­ma­tion, or oth­er set­tings.
   *For more infor­ma­tion, please refer to the ‘Set­ting a Pass­word’ sec­tion in the Advanced User Guide on cam.start.canon.
2. Enables firmware updates to be per­formed when the cam­era is con­nect­ed to the inter­net and new firmware is made avail­able on Canon servers.
3. Adds the abil­i­ty to auto­mat­i­cal­ly detect Flick­er at 100 or 120 Hz dur­ing Live View display.
4. Adds the abil­i­ty to reg­is­ter focus posi­tion as a pre­sets on the CR-A100 Cam­era Remote Appli­ca­tion. This abil­i­ty makes it eas­i­er to focus on sub­jects at the intend­ed dis­tance when the appli­ca­tion is used with Robot­ic Cam­era Sys­tem CR-S700R.
5. Adds the abil­i­ty to select [Case Spe­cial] to expand Ser­vo AF char­ac­ter­is­tics which is effec­tive for sub­jects locat­ed behind a net in sport­ing events, such as bad­minton or volleyball.
6. Adds sup­port for the Soft­ware Devel­op­ment Assis­tance Kit (EDSDK/CCAPI).
7. Adds a func­tion that simul­ta­ne­ous­ly pro­tects images when they are rated.
8. Improves image sta­bi­liza­tion con­trol for lens­es com­pat­i­ble with Periph­er­al Coor­di­nat­ed Control.
9. Adds sup­port for the Soft­ware Devel­op­ment Assis­tance Kit (EDSDK/CCAPI).
10. Adds to low­er the image cap­ture frame rate to help pre­vent over­heat­ing when con­nect­ed to CR-A100 in extend­ed remote shooting.
11. When trans­fer­ring images with voice mem­os via FTP, the trans­fer order pri­or­i­ty has now changed with voice memo (Wav) file being sent first fol­lowed by image file.
    If a voice memo is added to an image queued for trans­fer, the image and voice memo are now sent last.
12. Adds the abil­i­ty to set the num­ber of shots cap­tured in pre-con­tin­u­ous shoot­ing mode.
13. Adds the abil­i­ty to set [Air­plane mode] to shoot­ing but­ton customization.
14. Adds the abil­i­ty to enable [Expo­sure Sim­u­la­tion] when a flash unit is attached.
15. Improved AF track­ing dur­ing video cap­ture for sub­jects that are dif­fi­cult to focus on.

And the fol­low­ing errors have been fixed:

1. Fix­es an issue in which Err70 may occur when enlarg­ing an image after shoot­ing with [Black­out-Free Dis­play] set to “On” and [Ser­vo 1st image pri­or­i­ty/One-Shot AF release pri­or­i­ty] set to “Release priority”.
2. Fix­es an issue in which Err70 may occur dur­ing Blue­tooth com­mu­ni­ca­tion due to inter­fer­ence from oth­er Blue­tooth devices.
3. Fix­es an issue in which Err70 may occur when repeat­ed­ly shoot­ing in the “High-speed con­tin­u­ous shoot­ing +” mode.
4. Fix­es an issue in which Err70 may occur imme­di­ate­ly after start­up when shoot­ing with the elec­tron­ic shutter.
5. Fix­es an issue in which Err70 may occur dur­ing video record­ing in “FHD239.8P/200.0P”.
6. Fix­es an issue in which Error 70 may occur while film­ing in video mode with frame rate set to “50.00P” and [Movie Dig­i­tal IS] set to “On” or “Enhanced”.
7. Fix­es an issue in which Err70 may occur dur­ing shoot­ing when both [Pre-record­ing] and [Auto send] to image.canon are set to “Enable”.
8. Fix­es an issue in which the cam­era may stop func­tion­ing prop­er­ly when [Image Review] is set to “Off” and the mon­i­tor entered low bright­ness mode after pre-con­tin­u­ous shooting.
9. Fix­es an issue in which video record­ing may not be pos­si­ble when using Remote Live View shoot­ing in EOS Util­i­ty while out­putting via HDMI.
10. Fix­es an issue in which large RAW image files may not be trans­ferred via Cam­era Connect.
11. Fix­es an issue in which a hor­i­zon­tal line may appear momen­tar­i­ly in the viewfinder.
12. Fix­es an issue in which the cam­era may not con­nect to Wi-Fi 7-com­pat­i­ble routers.
