More from the floor, this time Tamron’s rather popular 18-270mm ultra-zoom lens. Seriously, 15x zoom. Now, I’ve talked in the past about the compromises inherent in a zoom lens that goes from wide to super-tele, but this doesn’t purport to be a pro lens that delivers the absolute best image quality ever in every condition. What it does do is save you a whole lot of swapping–covering about 27-405mm equivalent, and image stabilized too–which for some shooters is worth more. I applaud its ambition, and from the charts I’ve seen it performs just as well as any lens in its quality grade. And that’s really kinda boffo.
