To capture the Milky Way or other star-studded field, set up the A7R5 as follows:
- Shooting Mode: Manual
- Aperture: Widest available. With Sigma 14mm that would be f/1.4.
- ISO: Start with 3200 and increase if needed
- Shutter speed: Start with 15 to 30 seconds and test for longest exposure possible without getting star trails. The key is to not get star trails while allowing sensor to pick up as much light as possible from the stars.
- Focus: Manual or use live view with focus peaking to ensure sharpness.
- White Balance: start around 3900K and experiment if needed.
- Use a 2 second timer or a remote to stop camera shake.
- Capture images in RAW for most data
- Shoot in 3:2, not 16:9 aspect ratio to capture the most pixels
