One, which I assume is newer as it looks like what is posted online has a larger fisheye effect than the other version we have, which is much flatter. Not as concerned with the differing image output right now, but just wanted to seek clarification on why we might have two different lenses. Was this a known change? Which ones should we expect to receive moving forward? Or is the two different types expected?

From what I understand, all of our lenses we've received from starling kits.

On the Left is the (newer?) more fisheye lens and on the right is the flatter looking one.

Any help would be much appreciated, thanks!
