Olympus Pen and OM-D Timeline Release Dates and some Features

Back to Menu Page

This page is always work in progress, always deciding what details to add and what to exclude and of course adding new bodies as they are announced.
Any errors or suggestions please tell me at

As for colour coding, experimenting with         for best combination of features, and        for close second best, and         for close least desirable in current terms. Some columns may not be colour coded as user tastes dictate their usefulness. Be warned, this is a rather personal view of what features are desirable, the cells do change colours at times as I later decide what is better best etc.. The Date column is the date of the official announcement. The battery column colours are to highlight any differences. The fashion for "Mark II" and "Mark III" models annoys me and confuses some so I've adopted "Mk2" and "Mk3" here for clarity.

All user manuals found from here. Firmware level notices found from here.

Plenty of links because of the seemingly backward steps made to create this "beginner's" camera. It definitely should not have been named E-M10 Mk3, it is a different camera.

June 2020, Olympus is set to carve-out the imaging division to JIP by the end of the year. The usual happening is that JIP makes the unit profitable and sells on to some other company. No news if Olympus name will be preserved for any new products under the JIP/NewCo umbrella next year. Meanwhile until then Olympus branded products will keep coming.

More Notes.
Weather sealing not listed as a feature as there seems to be many reports of people with non-weather sealed cameras getting wet and having no problem, compared to people with weather sealed cameras getting wet and having problems. Answer:  when it rains, use an umbrella or enclose the camera in a plastic bag, leaving just the lens front exposed and with a lens hood on to help stop drops on the lens.

Pen line seems to have faded to E-PLx entry level and Pen-F enthusiast models. It seems that the Pen-F was a one-off experiment that will not go forward. Very likely that Pen line is finished apart from eventually the inevitable E-PLx line that seems to be so traditional.

OM-D line still seems E-M1 Mkx as usual flagship, but in 2019 the E-M1X has surfaced as the over-the-top we can do it flagship, E-M5 Mkx as enthusiast/beginner model and E-M10 Mkx as entry level with E-M10 Mk3 being pushed further backwards and definitely not an upgrade for current E-M10 users.

Andrzej Wrotniak's pages are definitely of help with Pen and OM-D cameras.
