E-M1 firmware update 4.0 review by Mirrorlessons.

Olympus OM-D E-M1 – Firmware 4 (Focus Stacking, Focus Bracketing and more)

Mirrorlessons published a review of the new E-M1 firmware update 4.0. They write:

By updating the OM-D E-M1 with all the latest specifications, not only are they prolonging the life of their flagship camera but they are also instilling brand loyalty by taking care of their existing user base.
What’s more, with the introduction of Focus Bracketing/Focus Stacking, the camera has also become one of the most interesting products for macro photographers. It can easily become one of those features that you can’t live without if you like this genre of photography.
With all the amazing technology we’ve been seeing from Olympus over the past few years, I am very eager to see just what the second generation E-M1 will bring to the world of photography.
