Let's see. As a walk around lens this is ideal. Compared to the DA*16-50 its:
Smaller Lighter Slower Less Range Both have WR. Its f2.8 on its wide end and f4 at 40mm. From the samples I saw it rendered very nicely. Much better than the 16-50. Out of focus areas and the roll off are rather smooth and pleasing. I don't know what minimum focus is, but I suspect its closer than the 16-50. I also have a feeling this lens would look really nice on some extension tubes. This looks like nearly a stack of primes and could replace having a 21ltd, 35ltd, 40ltd with one lens. For a zoom like this, I rarely shoot wide open, but it does look very usable there. Compared to the Sigma 18-35, it has a slightly different range and is much slower. I think they are both pretty sharp lenses, but I bet the limited resolves more. The sigma is also HUGE, lacks SMC/HD coating, and doesn't say pentax on the barrel. I know that if I wanted to shoot some street, I'd want the much smaller lens. I only wish it were say 16-40. The extra width would come in handy, but other than that this covers a range that is very useful, at least for landscape and outdoors shooters. I think it is way too expensive, but I have to admit that I really want one and a 15 and 70 to go along with it.
