Though the quality is far from perfect, I'm surprised by the ability of my little Samyang 50mm f/1.2 lens. Despite being built for an APS-C sensor, this lens works very well in low-light conditions on my Sony A7ii. And as it is for a smaller senor, it naturally gives vignette to my shots.
The shot was taken well into dusk as the stars in the sky were already quite clear. Not sure how the lens picks up so much light.
Beyond the technical stuff, I just love that "like-who-are-you" look on the frog's "face".
