Everyday contrasts.
Z6, 35mm 1.4 ais.
I´m a little concern about the dark line in the bottom of the frame. It was there for all the images today. Will have to try tomorrow if it is the lens or the e-front curtain at 1/2000th of a second -maximun allowed- Any other usual suspects?
I always like your color compositions, and this is no exception.
I would suspect that the bottom part of the frame is shadowed by the mechanical second curtain. The problem of the EFCS is that the first curtain is on (or even "in") the sensor whereas the second curtain is "over" the sensor. The slit has to be very narrow when you set the shutter that fast, and there always is danger of the second curtain to cast its own shadow over the image frame, especially along the edge where the image forming light hits the sensor in a more oblique angle.
Also, the EFCS may cause the inconsistent exposure, due to the fact that there is a discrepancy between the widths of the slit at the starting point and at the ending point. The slit is wider at the starting point and narrower at the ending point.
The EFCS of Olympus cameras is switched automatically to fully mechanical at 1/320 sec. or so and faster, even if you select the EFCS in the menu, presumably for the very reason.
