Hello,
I can't find anywhere the OLD version (v 1.0) of the firmware of this lens!

(v.1.1 is the only one available...)

Where could I find it ?

Thanks! E.S.
 
Curious, why do you want the old firmware? does it have some benefits over the newer one? I've actually got version 1.0 on my 20mm if you know of some way of extracting it
 
Before upgrading to 1.1 firmware for the lens :
GF1 + 20mm f/1.7 in PHOTO mode : Autofocus is fast, makes lots of noise (high pitch noise)
GF1 + 20mm f/1.7 in VIDEO mode : Autofocus is slow, makes lots of noise (high pitch noise)

After upgrading to 1.1 firmware for the lens :
GF1 + 20mm f/1.7 in PHOTO mode : Autofocus is fast, makes lots of noise (high pitch noise)
GF1 + 20mm f/1.7 in VIDEO mode : Autofocus is slow, makes lots of noise (high pitch noise + low pitch noise -> that didn't occur before for me)
 
I always use MF on the 20mm, but when I do use AF don't notice that much noise. I did not really hear a noise difference when upgrading the firmware but I might have missed it. If you want quiet AF try the 45mm Olympus.
 
There is no noise difference at all. 1.1 firmware has much more accurate autofocus on all lenses. It might be that you are just noticing the sound more than you did before, OR that something within the lens has gotten messed up, but I really really doubt that.
