| I'll take all I can get, but I've had two different Sigma 10-20mm lenses that I was less than enthusiastic about. I know that they work best at f/8 and beyond, but I've been happier with the images from my Pentax 12-24. I guess it's just wide envy, but I do wish Pentax made something a little wider. In my perfect world there would be a DA* 10-24mm, weather-sealed with an SDM motor and a constant aperture of f/2.8. Until then I'll content myself with the 12-24. Maybe I'll run some tests of the 12mm vs. a de-fished 10-17. Anyone else ever compared these two? |
