Perhaps you had a poor copy.
Or it's just Pentaxian standards. I'd be pretty tempted by that 18-135 despite my mislike of slow/variable aperture lenses. One zoom, sealed, is a nice idea if you otherwise only want to shoot primes.
I admit I expect less of zooms than some, so sometimes things are a pleasant surprise. Who's comparing what to what is always a question. Sometimes it's the light, too. My old Sigma 28-105 2.8-4 is pretty cantankerous in the bright, (Not for DR fans) .... no great shakes where I'd rather be shooting fast primes rather more wide open, but keeps impressing the crap out of me in the in-betweens where I actually want a zoom.
People say 'This is better *than* this,' too much. They should be thinking what's better *for* this. And know what 'this' is.
Zooms are for not- changing lenses.
What else.
