That's a very intersting comparison between the two lenses. I actually prefer the K 35 f/3.5 pic.
Too me, it has a greater/nicer depth of colour and the water droplets seem a tad sharper.
In pics #2, #3 and #4 i did sharpen them a little in Picasa.
From my testing so far, my 1.7 loves the 1.7 to 2.8 range. I can't wait to try some night shots with it. That's my next challenge
