I have been trying the Pentax 18-250mm lens and am considering going for the 16-45mm lens instead, and then maybe add a zoom lens down the road.
Just wondering what the opinions are of the image quality, lens speed, focusing, etc of the 16-45mm lens compared to the 18-250mm lens in the range of 18-45?
Thanks

Late to the debate, but I (as you can see below) use zooms, but never use super zooms. The IQ on good quality zooms in the 1:3 zoom range (16-50, 50-135, 24-90 stretches it a bit, 70-210) and I prefer those wth a constant aperture. I have also found that zooms at extremely long focal lengths are less than stellar in their performance (not counting the FA* 250-600/5.6, of course).
My recommendation would be for the 16-45 with its excellent IQ and constant aperture. You could then add longer ones. I personally can vouch for the AD* 50-135, which has a fast constant aperture, and a very usable focal length range. The DA* lenses have excellent image quality, in general.
