D4 to OMD-EM5

This is the m4/3 forum, not the Olympus DSLR forum so I haven't seen it "discussed to death" here.  I did bring it up here several months ago, but only one person replied.  The lag for wake up and power on is not very minimal though.  It is much longer than any of the various DSLRs I have used over the years.  For example, my old Canon 30D circa 2006 was 0.1 seconds according to Imaging Resource so more than an order of magnitude faster than the E-M5.  In this regard the E-M5 is a digicam and if Olympus wants to have a reasonably high performance camera then they need to do something about this.

I haven't taken a stopwatch to it, but the delay is interminable.

It depends on what you shoot.  I checked your websites and see why you have no problems with a long delay.

I had guessed that the sensor cleaning was happening at power on (but what about wake up from sleep mode?).  Some cameras give you a choice of power on or power off for this.  If this explains the long delay when powering on then it would be good for Olympus to give the choice to change it to power off time.  But, does it do a sensor cleaning when waking up from sleep mode also?  That doesn't make much sense and makes the wake up very slow.

I checked your websites and see what you shoot.  Yes, a 1.1 or even 11 second delay would rarely make any difference for what you shoot.  I do a lot of street photography though where instant reaction to quickly changing situations is more the rule than the exception.
