I just updated the FW on my IQ 4 150 (DB only).Very slow firmware update. Be aware...
I've done this many many times, on Phase and other cameras, but this is easily the slowest and longest one ever.
Took 12-15 minutes to complete, including a long period when nothing appears to be happening at all. Just wait. it will come back to life.
Some useful improvements, but still no 'ready' beep for exposure complete. wtf? How hard is it to carry over the basic functions the IQ3 had?
It went smoothly and took just short of four minutes.
Is the 12-15 minutes with the XF included?
Best regards
Trond
