Have ordered 60 macro as well, and the TC you recommend.
75 is great but I know it will not find much use.
EM1.2 is still sometime away, so thinking of getting a 2nd body 1st
Pen F ?
Received this tip from a friend who got the tip from Olympus Tech Support:
The default setting on the OM-D E-M1 Mark II has a limited number of Sequential Shooting/Self-Timer settings. There are a total of twenty (20) setting choices when they are all enabled. To add the remaining settings go to Custom menu Gear D1. Place a check in the remaining boxes.
Thanks Bobby. The 1st image is not too shabby for ISO 3200 in poor light IMHO.
The 2nd image is a super rolling silent shutter Hummer.
I believe quickly flapping/turning Hummingbirds are the ultimate test for silent/electronic shutters.
It will be interesting to see if the Sony A9 does any better!
Of course one can always fall back on using the mechanical shutter or simply delete funky looking images.
After all the camera is able to generate lots and lots of images in fairly short time!
Bobby I'll pass the kind words on, you know she doesn't read boards/forums.
Really she is elated that the M1ii has brought BIF into her life-she loves the challenge.
Interestingly she 'owns' an a6300/70-300G which is easily BIF capable; she just prefers
the Oly system.
I got a little too close for FF equivalent FOV of 1200 mm. 
1st image is good though!
