Do I need to keep a camera warm for a 2–4 hour timelapse at 25°F / -4°C?

I’m planning to shoot a 2–4 hour timelapse around 25°F / -4°C, from before sunset to after sunset. The setup may include a Sony A7S, lens, motion controller/slider, and battery power, with the camera moving slightly between shots. I’ll be near a car, so external power is possible. Is this temperature cold enough that I need to actively warm the camera or battery, and what practical options work best for keeping a timelapse setup running reliably in these conditions?

-4C for 4 hours, do not worry at all just do it. No warming no external packs. -4 is not that cold but to be extra careful if any of your gear takes AA batteries use Lithium AAs. Your camera's Lithium battery will be fine.
I was out a couple of weekends ago for 6 hours between -10C and -4C and the only thing I tried to keep warm was my fingers. No worries about camera, lenses or batteries. They can take it.

At 25°F / -4°C, you likely do not need to actively heat the camera body or lens for a 2–4 hour timelapse. Multiple photographers report cameras and lenses working fine for hours in similar or colder conditions.
The main weak point is battery performance: cold reduces battery effectiveness, so runtime may drop even if the camera itself is fine. Practical options:
- use a larger external power source if possible
- keep spare batteries warm and swap as needed
- if any accessory uses AA cells, lithium AAs handle cold better
- as a simple hack, chemical hand warmers rubber-banded near the battery compartment can help
If you’ll be close to the car, external power is the cleanest approach, especially if you’re also powering a motion controller. A battery warmer bag powered from 12V was also suggested as an option for batteries.
So the short answer: don’t worry much about warming the camera at -4°C; focus on reliable power, especially for long sequences and motorized accessories.
