This app is intended to ease shooting in manual and aperture priority mode with (legacy) prime lenses on the A5100 camera. It uses the OpenMemories Framework. While the app may work on other cameras, it was written specifically for use with the A5100.
Usage and features
Features are accessed using either the touch screen or the control wheel.
Touch the mode indicator on the top left to toggle between manual and aperture priority mode. The icon directly below it allows you to cycle between single shot, low speed and high speed burst modes.
The following parameters can be configured directly: Shutter speed, aperture, ISO, exposure compensation. Using the control wheel: Press the down button to select the parameter you'd like to change, then turn the wheel to change its value. Additionally, the enter button allows you to toggle between manual and automatic ISO and set a minimum shutter speed in aperture priority mode. Using the touch screen: Swipe left/right or up/down to change parameters. Tap once to toggle between manual and automatic ISO or set the minimum shutter speed.
Press the up button to cycle through display modes. This will toggle the histogram, metering display and rule of 3rds grid lines.
Use the zoom lever to activate focus magnification and zoom in or out. Half-pressing the shutter button ends focus magnification. You can change the position of the preview rectangle by either using the control wheel or swiping the touch screen. The enter button centers the preview rectangle.
The app also includes simple timelapse and exposure bracketing modes. Touch the icon on the left side and follow the on-screen instructions.
Long exposure noise reduction is disabled (normally forced in single shot mode for exposures >= 1" and in bulb mode on the A5100).
Exit the app using the help/trash button.
The app remembers the configured settings across multiple runs.
