Hi just wanting to know what lens are you using for this photo?
It was 8mm Samyang lens. Fish Eye. Manual Focus only.![]()

Fisheye lenses have that 'round' looking effect.
The one used is the Samyang 8mm circular fish eye but it's meant for APS-C sensor, so it'll look similar to a 'normal fisheye' - which is ~15mm or so usually on a full frame camera.
A full circular fisheye 8mm on a full frame will have the image complete in a circle with blackened surroundings.
