Thieves escaped with a haul that included two S2 models worth around £16,000 each, and a Vario-Elmar 30-90mm lens, alone believed to sell for more than £7,000.
The theft, at the Leica Store Mayfair, took place in early April but was not widely publicised at the time.
Leica also fell victim to an overnight raid in late January at its Café Optik, situated opposite the shop.
Items stolen then included an S2, a pair of Leica M-Monochrom cameras and an M8.
Speaking to Amateur Photographer, a Leica spokesperson said: ‘The incidents have been reported and our dealers have been informed properly.
‘The day-to-day running of the Leica Store Mayfair continues as usual.’
