Panasonic (Leica) DG Summilux 15mm / F1.7 Asph.

Nice lens, I've had my eyes on this one for a number of months. So far it hasn't disappointed, it's more than acceptably sharp wide open, just wish it was weather sealed.

I fully agree to Lenstips\' statements concerning image resolution. The Leica 15 F1.7 is a solid device rather than an exciting one. Central sharpness is average, but evenness of sharpness is excellent. It is the \'unavoidable\' small and light completion of your zoom lens collection which brings in fastness . I would not have bought it new but with 300 Euros I paid for a used one, I am happy.

I need a fast semi-wide for dark event work. Ive tried three versions of the Oly 17 1.8, and all have been pretty bad wide open and not that great stopped down. 20mm is not wide enough, I dont want the cost or weight of the 17 1.2, and the 12mm is too wide. At 1.8 this 15 is excellent in the center, and very good toward the edges. Stopping down to 2.8 sharpens things up nicely.

This lens works for everything. Its small and light, best lens M4/3 for trips.

Super fast and silky smooth, great for low light even with micro 4/3
