New functionality with OM-D E-M5 firmware update

E-M5 gets Small AF and Low ISO (100) via firmware update

Olympus has announced that a firmware update will be made available for the OM-D E-M5 that will add two key items of additional functionality we've seen in camera models from Olympus launched since the E-M5 was introduced almost two years ago. We haven't yet tried the new firmware update at the time of writing, but here's our take on what to expect:

1. Small AF targets; It's already possible to manually vary the size of a single AF point from large to small using the touch screen on an E-M5 but we suspect the firmware update will deliver similar options to the E-M1, with two sizes of AF point instead of just one an which will work in single, grouped and full matrix modes. Maybe there will be an increase in the number of points too, we'll just have to wait and see. The main benefit of smaller AF points is the ability to focus on smaller details that get 'overlooked' by bigger AF points. A good example is when focusing on fine details like tree branches. Normally the focus would fall on stronger details beyond the branches.With a smaller AF point there is a much higher chance that branch will catch focus.

2. Low ISO; The 16 megapixel LiveMOS sensor used in the OM-D E-M5 is designed to work optimally at ISO 200. However, it's not difficult to find yourself on a bright sunny day when using a fast lens, like the new m.Zuiko 25mm f/1.8, and the 1/4000th second fastest shutter speed limit has been hit. By introducing a Low ISO setting to extend the sensor sensitivity down to ISO 100 you can avoid needless over-exposure under bright light. Low ISO on the E-M5 may technically deliver lower quality image quality than ISO 200, mainly through slightly compressed tones, but based on experience with the same sensor in the Pen E-P5, which has a Low ISO setting already, ISO 100 is likely to be very usable.

We'll update this page once more information about the update is made available,
