IR Interview: Olympus 12-200mm, EM1X, Stacked Sensor Tech, And More

Image Resources had an interview with Olympus recently. Below are excerpts from the interview:

Olympus ZERO coating is general dichroic coating or multiple coatings
The original part of Olympus’ coating is how thin they can make it which creates a very low reflection rate that is half that of the competition
They cover the hermetically sealing (basically it’s just watertight not air) of the 12-200 in detail that would be lost in a summary
AF speed doesn’t come just from the motor, because how short the lens travels during focusing can be a bigger factor, but precision depends on the motors
Olympus’ lens designs can work well with stepping motors almost as well as linear motors
Open-loop control is typical of stepping motors but Olympus is using the feedback-loop control
Open-loop can have miss focusing problems though
The Olympus E-M1X’s EVF was picked for its superior refresh rate and panel quality
Readout speed, dynamic range, and color reproduction are as important or even more important than resolution when picking a sensor
20MP is currently the sweet spot for readout speed, dynamic range, and color reproduction
The E-M1X only really improves autofocus tracking performance for moving subjects
The default E-M1X AF-C setting is center-priority and it is extra sticky now in addition to customizable
The stacked sensor technology that Olympus developed back in 2015 doesn’t sound ready for cameras yet and Olympus says that breakthroughs take time to bring to market.
