Best Sony a6400 settings for portrait photography
Portrait settings aim for two things: sharp eyes and a soft, unobtrusive background. That means a wide-ish aperture, eye-tracking autofocus, and a flattering focal length. Here it's tuned to the Sony a6400.
Recommended Sony a6400 settings for portrait photography
Tuned for your Sony a6400
- Reach: its 1.5× APS-C crop turns a 300mm lens into about 450mm of reach — a real advantage for portrait photography, though it narrows your wide end.
- Clean ISO: modern APS-C bodies like the Sony a6400 stay usable up to about ISO 6400 — cap Auto ISO there so your shutter stays fast without over-cooking noise.
- Autofocus: use AF-C with subject/eye detection; it locks on reliably for portrait photography.
Set up your Sony a6400 for portrait photography
- Back-button focus: assign AF On to a custom button and set AF w/ shutter to Off (Custom Key settings).
- For action: use Continuous AF (AF-C) with a Wide or Tracking focus area.
- Eyes & animals: turn on Face/Eye AF and choose the right subject (Human / Animal / Bird).
- Burst: set the Drive Mode to Continuous Hi.
Exact menu wording can vary by firmware.
Why these settings
The eyes carry a portrait, so focus precision matters more than anything. A wide aperture creates the soft background, but go too wide and you lose one eye to the blur.
Common mistakes
- Shooting groups at f/1.4 and losing the back row to blur.
- Using a wide lens up close, which distorts faces.
