Hi Folks. I wanted to open with some of my comments to Barcelona. It was going to be a very short trip (3 days) and since the concept was travel like you are about to travel with a bunch of students the idea was generally to go light. That said a trip to Barcelona would likely be a once in a lifetime. I was kicking between the K3 or my Q7 'system' and ultimately figured I just trust the K3 more. Then it came to lenses. I knew I wanted to get as wide as possible so I felt I would need the 12-24 or the 15mm f4 even though the 15 is so light. The chance I might see a bird or two that I would want to photograph meant I needed to bring my 55-300, and the fact I might have very low light situations meant I threw in the 50mm f1.8. It proved a good set of lenses to bring, but was a bit bulky. As I wanted to bring only one carry on I decided to sacrifice clothes. Good choice! As big as it is there is a lot of detail in the Sagrada Familia that I just couldn't have gotten without a longer lens, especially on the outside of the building. It's very whimsical art and as impressive as the building is inside, the outside is a lot of fun. Statues on the Sagrada Familia, k3, 55-300 The K3's ability to shoot good images at such low light was very impressive. I didn't need to 50 f1.8 very often to honest as the f4 on the 12-24 was plenty fast enough Crypt Church in Gothic Quarter. K3 and 12-24 and then there's just the crazy stuff you can get with a wide lens.. K3 12-24 and yes I did get a few bird images (not a lot). Amazing how a couple of lenses like that and a great camera can really add some fun into travel images.
