I've realized that I'm not in love with my 20mm - I don't LOVE the pictures it makes. Also, I would much rather have a wide angle zoom for more functionality after my recent trip to San Diego with my family. So I'm left with the question, which wide angle zoom is a good replacement for my 20? Anyone else replace with their 20 for something more spectacular? And I know the love people have for the 20 so it's not a knock on the lens at all. Much like everything else, it's just a matter of personal opinion. And since I don't have any experiences with the other lenses out there, I would like to know yours! I also think in the future, I'll be purchasing the PL25 but for right now I would like the functionality of a zoom.
