Apart from a macro lens, I think everybody with an interchangable lens camera (this used to be simply DSLRs but now of course there’s a load of mirrorless out there as well) should have an ultra-wide angle lens (UWA). They’re just so much fun! One of the things I like doing is sticking the lens right up close to geometric architecture and watch the curvature of time and space… well kind-of. But do look at those egg-shaped atoms!
The weather here really helped to put a shine on the Atomium.
