Hello all! I'm very excitedfor a city break to Amsterdam this weekend! Usually when I go on short trips with friends, I've taken my kit lens for day time and my 20mm for evenings and inside touristy stuff. This week, however, an Oly 12mm has arrived. Now I'm thinking about taking the 12 (along with the kit) and leaving the 20. I'll miss the quasi-pocketability, but for interiors I think the extra width will be helpful. Is there anything I'm not considering?
