As I said in an earlier post, I took way too much camera gear when I went home to South Australia. My main lens when I was there was the Pentax FA 28-105 3.2/4.5 and the Pentax DA 18-55 3.5/4.5, two great walk around lenses, even though they do overlap somewhat in certain ranges. These two lenses woked best for me during the daytime and dusk, but for sunsets, night shots and general low light situations I changed to the Pentax M 50mm 1.7.
