Melbourne’s CBD office market may be in dire straits, but famous German camera maker Leica is betting on the city’s retail sector mounting a strong comeback after opening its biggest global store on Little Collins Street.

Billed as a mecca for photography enthusiasts and lovers of its legendary high-definition cameras, the flagship boutique – the result of a multimillion-dollar refurbishment of an old Art Deco building – spans four levels and offers 540 sq m of experiential retail space.
