I'll be attending Oktoberfest and I'm wondering whether to bring my P20/1.7 or P14/2.5 with my GF5. It needs to be small (pocketable, if possible) and it should be wide enough to take in the large tents from the outside as well as snap some photos of my wife and I from close range (i.e. taken by a person sitting across a table from us). The 14mm is the smallest and widest, but I'm afraid it might not be fast enough to get clear shots inside the tents with indoor lighting (example). But the 20mm may be too narrow for close range shots. Thoughts?
