Originally posted by dmort I would be unlikely to bring both the 16-50 (which I'd have to buy) and the 18-135... However, if that travel lens comes out and is available in time, at it is WR, maybe that would be a good choice. Although, it isn't very fast...
The more I've thought about it, the more it seems that my current 18-135 plus 1 fast, "normal" length lens is the right combo. Now I already have the 43mm... maybe I'd be good with just those two? I am thinking about the 55 though, as it is WR. But the new 1.8 is tempting too, since it is cheap. I am also considering the 30mm sigma and, although it is out of my price range, the 31mm.
I spent many weeks in Finland over the last 10 years or so, and I have a lot of images from my trips there. I love the country and the people of Finland and have many fond memories of my time there.
I am fortunate to have a fairly large collection of lenses to choose from, and over the years, I took most everything other than longer teles with me on my trips. Most often, I traveled with the 16-50 and 50-135, as the range they cover is useful for landscapes, street shots and portraits. I did take a monopod on some trips, but found that it was a hassle to carry and I ended up not using it much, so I stopped bringing it.
Over time, I learned to travel light, and decided to try some trips with primes only. I took the 31 and the 77 only on several trips, but sometimes wished for something wider than the 31. Changing lenses can be a bit of a hassle in the cold, however.
Helsinki is a wonderful city. I spent most of my time there wandering around the entire city on foot sort of "street" shooting whatever caught my eye. I did not venture out into the countryside around Helsinki, however, as my trips there were mainly on the way to Kuopio, where I could get out into the country more easily.
The winter weather is pretty much as described earlier, with many overcast days and lots of grey. If you do get a clear day or two, the light is WONDERFUL. It is long and warm much like early morning or late evening "golden" light we lower latitude photographers love so much. If the sun is out, do not waste any time, however, as it will not be out very long!
If you only get grey days, put your minds eye into black and white mode and visualize the scene that way. That said, one thing I really liked about Finland was the colors: lots of nice colors on homes, doors, window frames, children's clothing, boats, and the long golden light has a way of picking out colorful subjects against the background.
I never had any any problems with non-WR lenses on my trips, so to get back to your lens question, I would take the 18-135 and the 43. I never had the luxury of having the K5 DR on my trips, so you can probably get most of the walking around shots with the 18-135 and use the 43 for portrait and low light work. I have the 43, and while I find that it is a bit of an odd focal length on the APS bodies, it is small and capable of capturing very special images.
Have fun and make sure to post up some images when you return.
