Should I get a full frame or APS-C mirrorless?

The trade-off in one line

Full frame buys you ~1 stop of low-light performance and shallower depth of field. APS-C buys you smaller bodies, smaller lenses, lower prices, and more reach with telephoto lenses.

When full frame is worth it

• You shoot weddings, events, or low-light work professionally.
• You need maximum dynamic range for landscape or commercial work.
• Shallow background separation is core to your style.

When APS-C is smarter

• Travel and street where weight matters.
• Wildlife and sports where the 1.5x crop factor extends reach.
• Vlogging — APS-C bodies are smaller and easier to hold at arm's length.
• Budget — a great APS-C body beats a mediocre full frame.
