Mirrorless camera systems can be a delight to shoot with for traditional landscape photography, since you’re almost always shooting at lower ISOs (so you might get away with shooting on an APS-C or Micro Four Thirds system) and you’re not shooting at faster apertures.
Nightscape and astrophotography, however, are a different story with mirrorless cameras. You’re usually shooting at a high ISO and with a wide aperture, which require a bigger camera body and lenses (in some cases almost as big and heavy as an entry-level full-frame DSLR). This can make things a little tricky with the “limitations” of a mirrorless camera.
With that said, the camera sensors from Sony and Fuji in particular, not to mention the selection of lenses, have been getting more and more phenomenal in recent generations, and they can be a delight to shoot with if you learn these five simple tips for maximum performance!
1. Power Source
First and foremost, the primary obstacle that any mirrorless nightscape photographer needs to overcome is ensuring that they have sufficient power to last the night. Whether you are doing ordinary stills photography, or all-night timelapse photography, it will not be enough to simply pack one spare battery (or even two).
Unfortunately, spare batteries (top brand ones) can be $50 a pop at least, and they don’t have great capacities either. The majority of Sony mirrorless cameras, from the full-frame 7-series to the point-and-shoot RX10 series, are still using a 1050 mAh battery, the NP-FW50.
