Originally posted by Mike Bokeh Ash, I can't comment on any of the other lenses, as I've never tried them, but I can say that I am very pleased with my Pentax 16-45. It's very sharp at almost all settings.
I'd recommend trying to get a little more money together and get the 16-45. This lens is a keeper.

Mike & Ash,
Thanks for the great input for the Pentax 16-45, I seldom think of that lens as I always count on my kit's lens for the wide angle. I have not thought about that lens. But what is holding me on the 16-45 is my collection of prime in 24, 28, 35 and 50 and it looks to overlap with my primes too much that I prefer a zoom in the range of 16 - 80 for my day to day use and hence my preference to Tamron 28-75 and Sigma 17-70. If the Sigma is f/2.8 throughout, I won't even get into the hesitation that I am in. Nothing is perfect but f/2.8 is my dependable aperture for street photography in night shooting that I truly enjoy
Samples of shots in new year done with a Vivitar 24mm f/2.8 done on new year after fireworks, I love the 24mm and I may yield the priority to Sigma 17-70 if it has f/2.8 at 24mm
All are hand held shots done with Vivitar 24mm f/2.8 and Pentax FA 50 f/1.4
