Admittedly, I'm only using a 300mm F4 Canon FD lens, but what is the weird shape on the bottom of the Moon?

Is it something caused by my lens, or is it a natural phenomenon?

At the bottom? All I see are craters at the bottom. The craters have distorted the moons shape around the edges.

There is a cluster of large craters at the bottom - you seem to have picked some of their ridges.

PS: That large crater in the cluster is Tycho:

That's a spot on moon you got there, great shot, don't worry it's meant to be there.

You'll never get a lot of detail in a full moon shot. The sun is hitting it head on so there are minimal shadows. Your photo though as others said, shows crater detail at the bottom. Perfectly normal.
