Now that the K-1 has come out we have some figuring out to do regarding which lenses to take on a trip, given that many of us have become accustomed to the APS-C format and know the field of view of our lenses by heart on our K-3's, 5's, 7's, etc.
The task doesn't get easier when you contemplate to carry, say, a K-3, alongside the K-1, and want to bring just the right lenses. The need to be traveling light must also be taking into account.
You guessed it, I'm planning a trip (to Lofoten, Norway). The K-1 with the D FA 24-70mm is a given, but how do I cover ultra wide angle and long telephoto without getting bogged down with weight?
That's why I thought that it is time to revisit the table below and use that to help me decide. I hope that the table would be helpful to others as well.
