It depends on your budget, For high-end 24mm lens, get Sony FE 24mm f/1.4 GM or Sigma 24mm f/1.4 DG DN Art.

For compact & lightweight lens, get Sony FE 24mm f/2.8 G or Tamron 24mm f/2.8.

There are several great 24mm lens options available for Sony E-mount cameras:

1. Sony FE 24mm f/1.4 GM

• Pros: Excellent sharpness even wide open, beautiful bokeh, fast f/1.4 aperture, weather-sealed
• Cons: Large and heavy, expensive at around $1400

2. Sony FE 24mm f/2.8 G

• Pros: Compact and lightweight, very sharp, fast and quiet AF, less than half the price of the GM at around $600
• Cons: 2 stops slower than the f/1.4 GM, some distortion

3. Sigma 24mm f/3.5 DG DN Contemporary

• Pros: Most affordable option around $300, very compact, decent sharpness and contrast
• Cons: Slowest aperture at f/3.5, build quality not as good as Sony lenses

4. Tamron 24mm f/2.8 Di III OSD M1:2

• Pros: Very sharp, fast f/2.8 aperture, affordable around $350, 1:2 macro capability
• Cons: Slower AF than Sony lenses, some chromatic aberration

Ultimately, the best 24mm lens for you depends on your budget and needs. For the highest optical quality and low light capability, the Sony 24mm f/1.4 GM is the top choice if you can afford the price and size. For a more compact and affordable option that still delivers great IQ, the Sony 24mm f/2.8 G is an excellent pick. And for those on a tighter budget, the Sigma and Tamron provide very good performance for the price.

I love my FE 24mm f/1.4 GM.
