| I have that pair of lenses and really enjoy them. The 50-135 is just stellar, and the 16-50 is gaining in enjoyment everytime I use it. Both are quick to AF and give great colors.
I will say, however, that I didn't like the 16-50 on my K10D. AF was much more hit/miss and I got bad purple fringing in high contrast shots. Since moving to the K20D, the 16-50 problems went away. I now confidently use both lenses, and enjoy doing so. |
