The first luck people is trying their third party lenses on the own E-P1. I will give you a little overview!
– The E-P1 with the fantastic Panasonic 7-14mm lens
– the Panasonic 45-200mm lens
– with the Leica Noctilus 50mm f1.0 lens
– with the Voigtländer 15mm and Voigtländer 50mm f1.1
– with a undefinied combination of lens and adapter!
– Olympus E-P1 Leica Summicron 35/2
Feel free to add more lenses to the list by commenting this post!
