I've done some checking.
Not excusing user error, but it's poor design on the EM1 2.
The button sits out on its own waiting to be caressed and.....
The EM52 button is round and sits inside a small collar. I've pressed the button towards the collar and nothing.
You have to press to within the rim before the pin actually disengages.
I also think, but maybe wrong, the button on the EM52 is "snappier". The pins both work nicely in 5 and 1 but the button could have (should) more resistance IMO in manufacture. All three feel to have same spring loading.
Be interested to hear from version 3 users and the button design.
Anyone with an EM1 3? And EM5 3? How is the button on that? Sticking up like a sore thumb or neatly in its own housing.
I've owned EM5 1 and 2 for yonks and with 60mm, 75-300mm, 40-150 2. 8, 12-40 2.8, taking them off and on at will and never had an issue.
Also the G9 users? How's that button setup?
Thanks
