Tamron AF18-250mm f/3.5-6.3 Di II LD Aspherical (IF)
Closer than ever to “one lens does it all”
My favorite photo subjects are birds, and I like to travel light, so I do most of my shooting with one lens, a fast telephoto. But between close encounters of the bird kind, I often come across lovely landscapes and flowers that require a much wider or closer viewpoint. The 18-200mm zoom lenses for my small-sensor digital SLR aren’t quite long enough for most birds and other distant wildlife, while the 28-300mm lenses aren’t really wide-angle on such D-SLRs. So I have to carry another lens or two or miss out on those non-bird photo ops.
At 250mm, the ƒ/6.3 maximum aperture slows autofocusing some compared to my 300mm ƒ/4 bird lens, but that 300mm weighs nearly three times as much as the 18-250mm, costs more than twice as much and provides just the one focal length. And the 18-250mm gave me some bird shots I wouldn’t have captured with the 300mm because I wouldn’t have taken the big 300mm into that rough terrain.
Currently, the 18-250mm is available in Canon, Nikon, Pentax/Samsung and Sony/Maxxum mounts.
