What m4/3 lens do you use most often?

Hands down, the native M4/3 lens I use most is the Voigtländer Nokton 25mm f0.95. It mostly lives on my GH2.

The rest of my native lenses I use for different purposes: 7-14mm, SLR Magic Hyperprime 12mm T1.6, 14-140mm, 100-300mm & 20mm.

I tend to use more adapted manual lenses than native M4/3. Nikon and Voigtländer mostly and mostly these: Voigtländer 75mm f2.5 Color Heliar & Nikon 105mm f2.8 AI-S macro.
