Revert firmware from v1.61 to v1.55

how to revert firmware from v1.6 or v1.61 to v1.55? or maybe reinstall the firmware from a fresh download? with v1.61 there is a noticeable pregnant pause shifting from screen to EVF use takes longer than 2 secs; had multiple camera-freeze requiring battery eject to work again, and more times coming back to operation with camera recording 0MB, non working jpeg files only instead of DNG+JPEG in settings.  had to do a factory reset to enable proper camera operations.

I also noticed it takes longer to go from screen to EVF with firmware 1.6. I thought it was in my imagination; but now that you are mentioning, it seems more real!...

same feeling here. and I also think that exposuere is sometimes a bit delayed. can't be AF, is even worse with manual objectives. or is this just in my imagination?

I totally agree with what you said; therefore, it shouldn't be the fruit of our imagination!... Let us hope they would improve that!

Sounds like sn SD card problem.

 

 

eliminated that probability at the first instance of getting 0MB jpeg files; and tried to use Scandisk, Lexar, transcend, leica and 95mb, 10000x class10 HC; 64, 32, 16, 8Mb's, new and used. was not able to isolate camera freeze on a particular SD card.

 there is some sort of pause, when you transfer your field of view from screen to EVF... an instance of "as if taken by surprise, and scrambling to give you the view you wanted."

I seem to struggle with using AF more in v1.6 than in v.155 perhaps it is just me.

Is there a way to revert to older firmware? tried installing v1.55 over v1.61 i get "firmware is up to date"

 

I am sure it CAN'T be done.

I have never heard of any equipment in which you can downgrade firmware.
