Brightin Star 50mm f1.4 for Sony APS-C Lens Review ep.514 

I haven't tried the ttartisan lens. But compared to the Viltrox, the key difference is in build quality. Optically, they are very similar. I'd give the edge to the Brightin Star for IQ. The Viltrox is much cheaper, but has a plastic body. This makes it less premium but lighter and smaller. So if you prefer a smaller/lighter lens or on a tight budget, then you'll be very happy with the Viltrox. The Brightin Star is a much more premium lens with all metal build and is weather resistant. Optically, it handles ghosting and flaring much better. I think it also has slightly better contrast and color. Also, it's a brighter lens at f/1.4. Ultimately, you'll get better quality in lower light situations. So if you don't mind the size/weight, I think it's worth going for the Brightin Star.

@@RobTrek thank you for the reply!! Yeah so far I’m leaning more towards the brightin star but I’m going to check out more videos on the ttartisan since I’m debating if I should sacrifice a longer range for a brighter aperture

We'll see. They have many MF lenses. This is their first AF lens.
