Thanks! I’m using a Canon EOS rebel t7. I took that photo with a sigma 150mm (used, always buy used). Amazon link here.

The price may seem a bit much, but it’s worth it. The lighting can be hard to get right, but so far, I don’t use any sort of diffuser. When necessary, I use the camera’s built-in flash.
Hope that helps!
