Summary: And the price is right too. I usually don't like Tamron lenses but this one is an exception. Can be almost as sharp as the Canon 180mm and is good enough for this fussy-about -sharpness person.
Tamron 180mm f/3.5 Di LD IF Macro 1:1 SP AF review by MediaGuru
23 November 2012
Summary: I spent countless hours researching for a good macro lens and basically had it narrowed down to the Sigma 70mm, Tamron 90mm and 180mm. I read complaints about how close you have to get with the 70 or 90mm lenses and decided that any extra distance I could place between myself and shy animals and bugs would be nice (this lens is supposed to be able to focus at 18.5 inches). I am not sure if this is normal or typical of a macro lens, but I was able to focus at 10 inches.
Pros: Excellent IQ, smooth focus ring, very little distortion, little to no chromatic aberration or vignetting
Cons: Wiggles ever so slightly when mounted to my Sony A57
Good Value, The filter holder rotations can be an issue. It is really a f5.6 lens

Summary: This lens is a good value for the money. You can use it as general telephoto lens and Macro lens. One issue that you should think about is the front filter holder of this lens rotates in order to be convenient to use filters that need rotations while the hood is on. This is helpful when you need to rotate a filter with out having to stick your hand inside the hood or remove the hood to use these types of filters.
Summary: Pros: Extremely sharp Smooth focusing Lighter than a Canon L lens (easy to lug around) Nice rubbery tactile focus ring Circular polarizer rotator ring Longer distance for 1:1 macro Black (doesn't stand out like the Canon) Has a Lens collar Versatility (180mm also good for portraits) Cons: Slowest autofocus ever on a lens Lighter than a Canon L lens (less resistant to impact/mirror slap) Depth of field 1-2mm! As you can see, the pros far outweigh the cons.
Summary: Maybe some of the negative reviewers got a bad copy of this lens, or Tamron has improved it... but the autofocus is *very* quick even in indoor low light, the working distance is fantastic, build quality is excellent, and the optics (the important part!) are amazing. Sharpness and color rendition are superb, even from just some hand-held shots. In terms of image quality this is on par with the Canon 100mm macro which is my favorite lens. Or maybe it was....
Summary: Less than half the price of the Canon L version, with reports of the Tamron being superior optically. My experience with this lens so far: 180mm is an excellent working distance for small objects, flying bugs, timid birds. AF stinks and is noisy. I never use it. There is no focus lock. MF rocks, and the big fat focus ring is easy and fun to use. I'm a handholding ninja, but many people might feel more comfortable putting this on a tripod or monopod.
Summary: i got this lens after reading professional and users reviews from several sites and i'm pleased to say that i got the expected results. sharp images and nice bokeh. the AF isn't great but for macro i almost always uses manual focus anyway. this lens feels very solid , it's very good lens to work with,both on a tripod or hand held.the focus ring is also very comfortable to use,the price-quality is great and the lens is a great purchase.
