The Olympus OM-D E-M10 Mark IV is quite suitable for northern lights photography, albeit with some limitations, but it offersSeveral features that make it suitable for this type of photography:
## Image stabilisation
The camera has 5-axis image stabilisation, which can help to minimise camera shake, which is particularly useful with long exposure times.
## High ISO performance
The camera can shoot up to ISO 3200 without serious loss of quality, and ISO 6400 can also be used if required, although this may slightly affect image quality.
## Live Composite Mode
The camera offers Live Composite Mode, which is particularly useful for shooting star trails or other long-exposure subjects.
## Electronic viewfinder and LCD screen
The electronic viewfinder and swivelling LCD screen make it easier to operate the camera in different positions, which can be useful when shooting the Northern Lights.
## Fast autofocus
The camera has a fast and accurate autofocus that works well even in low light.
Despite these advantages, it should be noted that the camera does not offer the same image quality as higher-end models in the Olympus range, especially in extreme lighting conditions. however, the performance of the E-M10 Mark IV is usually sufficient to achieve good results in northern lights photography.
If a high continuous shooting speed is desired, then this is certainly the wrong camera. This is the cheapest entry-level model from Olympus / OM System. They always save on the buffer. 17fps yes how long? Then the OM-1 would be the better but also more expensive choice. You get what you pay for. Like everywhere else.
It all depends on the requirements. In general, unfortunately, you can't get very far with 1500 francs. What kind of night photos are we talking about? With a tripod? Without a tripod? Without a tripod, you need very bright lenses.
For moving lenses, there are better cameras. The cheap Olympus cameras are not known for their good AF-C. This would be necessary for that.
I would also look at the Fujifilm X-S10. Also, when shooting with a camera, it is always best to know at least the most basic relationships between shutter speed, aperture and ISO.
