Thank you for an invitation!
We were mostly in Berlin, and Hamburg, and made 2 days trip to Czech Republic (Prague).
So, we are back form our short trip... short story - I got 10-24 at the end.
I went to Saturn mall in Berlin to handle both lenses, and found that size/weght difference is not that dramatic, as some peple say.
Yes, zoom has larger front element, but it's not 18-55 vs 16-55 difference.
And I've found that 4mm at the wide end is a huge difference!
Well, I have not used 10-24 a lot in Berlin, because it has plenty of space, so you can zoom out with your feet mostly, so I had 18-55 attached most of the time.
Things have changed when we got to Prague and Hamburg. There I used 10-24 most of the time - with tall Prague cathedrals like St. Vitte's, 10mm was a saviour lens,and Hamburg has pretty tall and huge buildings, not always possible to shoot with 18-55.
I also used a 55-200 in Berlin Zoo, and on the boat trip on Alster in Hamburg, and 35/1.4 when needed more low-light perfomance, but 60/2.4 really was used only once, wish I'd leave this lens at home at all.
