Lens options for OM-D ???

I have had the OM-D with kit lens 12-50 for about a month now. My main shooting is landscapes, scenery, and architecture. Previously I shot almost entirely with the 12-60 and E-3.

I am curious about a couple alternate options to the 12-50.

1. How much better is the Pan 12-35 than the 12-50?? Price difference is 3-4 times for the Pany and I am curious if the benefits are there, or

2. Should I consider the combo of Oly 12mm and 45mm primes for about the same money as the Pany 12-35mm, or

3. Just be happy with the 12-50 knowing it's not the best, but not the worst... maybe mid-range

Would appreciate your thoughts and input. I have read most of the reviews, but am interested in on-hands experience.

Here are a couple of recent shots with the 12-50 and how much better would they be with the 12-35mm?

Thank you in advance,

Gary
