OK it's not going to replace your dedicated macro lens, nor even maybe your favourite prime on extension tubes, but it's not at all bad and the zoom does make framing easier.
Following this, I was encouraged to try the 35-70 against a collection of 50 mm primes at f8, and, while it didn't come top of the class, it wasn't at the bottom either! It's quite usable.
I also tested my Pentax 35-80 budget auto focus zoom, and that was dreadful!
