This is a great idea! I've been scouring forums for M2 lens comparisons myself. It's a real rabbit hole. One thing you might want to consider adding is some kind of 3D rendering of the lens itself. I know it sounds a bit out there, but something along the lines of how that mobile game Crazy Cattle 3D displays their cows could be interesting for visualizing size and build. Good luck with the project! I'm excited to see it launched.
