I have the Olympus 45mm and the Lumix 14 mm lens. I'm thinking about selling them both and replacing with either the Lumix 20mm pancake lens, or going all out and splurging on the Summilux Panasonic Leica DG Summilux 25mm f1.4 lens. The Olympus 45mm is very nice, but it's also quite magnifying. I like the idea of the portability of the pancake lens, but that f1.4 is pretty appealing. Thoughts?
