Tamron’s SP AF180mm F/3.5 Di LD (IF) 1:1 Macro; A Macro Tele Lens For 35mm, APS-C, And Digital SLRs With Full-Frame Sensors Page 2
One useful feature found on the Tamron 180mm f/3.5 Macro is a striated Filter Effect Control (FEC) ring at the very front of the lens barrel. Turn it clockwise and a geared internal mechanism causes the front filter mounting ring to rotate counterclockwise (and vice versa), making it easier and more comfortable to control the effects of polarizers, graduated filters, and those special-effects filters that provide variable effects. The FEC control ring has a very smooth action, and it's certainly easier to grab this 3/8"-wide ring than the narrow rings found on most filters. We also liked the legible distance scale, which displays both footage and metric distances in white-on-black, and magnification ratios in orange-on-black, all under a plexiglass cover window. The abbreviated depth-of-field index (f/32 only!) is kind of useless except that it highlights the focusing index, and we note that one casualty of having a removable tripod platform (which we like) is that this one lacks vertical and horizontal orientation detents--there are only orientation dots on the barrel--no great loss.
The Tamron 180mm f/3.5 Macro is beautifully finished in satin black with gold
accents and comes with a substantial (4" long!) and very effective lens
hood. Happily the big hood is very light, and it stows by bayonetting in reverse
position over the front of the lens. We shot hundreds of pictures with and without
the hood, and the only time we noticed any visual benefit was in shooting in
extreme high flare situations, e.g., with harsh light striking the front surface
of the lens at an acute angle.
The Bottom Line
Overall, we were very impressed with the imaging performance of the Tamron SP AF180mm F/3.5 Di LD (IF) 1:1 Macro. It is certainly capable of delivering superb sharpness over the entire aperture range along with excellent bokeh (that is, smooth out-of-focus image quality with defocused images retaining their shape). We would therefore recommend it for consideration by any serious enthusiast or pro shooter who takes macro shots of small distant subjects, or who requires an excellent quality 180mm telephoto that provides outstanding close-up capability.
While lenses having about twice the focal length of a normal lens (the 85-105mm range in 35mm) have long been regarded as the ideal portrait lenses, the longer Tamron 180mm also acquitted itself remarkably well for outdoor portraiture. It provides a pleasing perspective, excellent definition, and a shallow depth of field that helps make the subject "pop off" the agreeably soft background. For those who prefer to carry the lens separately (as I do) it comes with a good quality soft, padded zipper case with strap. No, I'm not about to trade in my 90mm macro anytime soon, but after shooting with the Tamron 180mm f/3.5 Macro for about a month it's now at the top of my "next lens" list.
