Shutter life expectancy

Back in the E-series days Oly published a spec for the projected life of the E-3/5 shutter, which was a more robust unit than the 1/4000 shutter in the three-digit cameras. It may have been 100k but don't quote me.

With 5fps top drive speed one had to work hard to achieve 100k images but my OM-Ds have all had 10fps at least, and the E-M1ii is significantly higher than that so hitting 100k is child's play. With no flipping mirror there's a lot less mass in movement so hopefully the mirrorless segment benefits from its simplicity with greater dependability. (Does it matter the shutter parks open?)

Here is a message I wrote many years ago, discussing how the Mirrorless (G1) focal-plane shutter operates vs. a "conventional" stay-closed FP shutter.

and here is another, from a different thread, that descended into more detail about shutter stress issues:

Regarding shutter life in general:
From way back, the traditional Canon or Nikon pro-line (mechanical) bodies were expected to last well over 100k shutter actuations. Pretty good, but the Leica M (mechanical) body was expected to last into the million-actuation territory. But even that is not exactly the same thing as "no problems during working life". For those clockwork-regulated shutters, one would expect to have them checked, cleaned/lubed and adjusted every few years to stay in top and well-regulated condition.

FP shutter design moved on to electronic speed regulation and solenoid release and reset mechanisms, curtain design moved from cloth or foil on rollers to overlapping metal leaves, and lately even more electronic control of curtain travel and braking (the latest Panasonic shutters have very low shock/vibration levels, and note that the newest Leica M10P features a new extremely quiet shutter that may use some of that Panasonic engineering (I don't know that but it's reasonable).

We already have all-electronic "shutter" operation offered in most cameras, and soon we may see the beginning of the end of mechanical shutters, as so-called "Global shutter" designs begin to be used.
