I'm looking to add a versatile 50mm lens to my Sony mirrorless camera kit. I've heard great things about 50mm primes, especially for their sharpness, fast aperture, and compact size. I'd love to get some recommendations from the community on the best 50mm lens options for Sony E-mount cameras.

Some key factors I'm considering:

1. Image quality and sharpness
2. Maximum aperture (preferably $f/1.8$ or faster)
3. Autofocus performance
4. Size and weight
5. Value for money

I'm primarily interested in using this lens for:

• Portrait photography
• Low-light and indoor shooting
• Street and travel photography

If you have experience with any of these lenses or have other recommendations, I'd greatly appreciate your insights. Sample images and real-world experiences would be fantastic!
