Sony 50mm F1.8
50mm is good for close-ups, medium shots, and almost every shot.
You can also use viltrox 50mm.
Sony 24mm F1.8

viltrox 35mm 1.8

On buying new lens try to figure out what kind of shots you are actually looking for! If you buy a new camera then its better to go with 24mm/35mm, then get a 50mm And also do some Yt research for this!

Sigma 30mm F1.4
Sigma 16mm F1.4

These are the best for crop bodies at a cheap price. If you have money ten go for Sony!

I will update this page with some more details in the future.

Thank You!
