Originally posted by passigatti Horrible lens, useless crap! The only 18-200/250 that ever delivered is the 18-200 VR from Nikon. All other Tamron/Sigma/Other creations in this extreme zoom range just plain suck. Get the Pentax 17-70mm, very sharp for a zoom. And yes, I tested all 18-200/250 lenses. -B
Your post count and this "helpful" comment suggests a troll. Run along now. Again, for those interested in facts, the 18-250 is an excellent lens. As I mentioned, I have run tests in comparison with the excellent DA*50-135, that costs about twice as much. Here is a picture from each lens at 100mm.
Note that these are both 100% crop. Any less crop, and you can't even tell the difference. I find myself using the 18-250 more and more because it is just so versatile.
Which one is the DA*?
