Renowned photojournalist Tom Stoddart was among guests at the invitation-only event which was hosted by Leica Camera Ltd managing director David Bell.
The tiny shop first opened as a ‘pop-up’ store before Christmas.
Earlier in the day, Leica announced a special camera kit as part of celebrations to mark 100 years of Leica photography.
Leica already has a store in Mayfair, situated on nearby Bruton Place, which remains open as normal.
