Last week I went to Foto Konijnenberg to look at two lenses I had been reading about. The 70-200mm f/4 L IS USM and the 24-105mm f/4 L IS USM. Both are excellent lenses and real “L” quality. The build quality was much better than the EF-S 17-55mm f//2.8 IS USM I had so after doing some test shoots outside I was really liking the 24-105 but I had a large overlap with the 17-55. And then the salesmen made a very good trade in offer so I decided to get the 24-105. So now I only need a wide angle lens 14mm 2.8.
