Summary: After shooting with my 105 mm I wanted to add another one to my collection. I found shooting with this lens I had to give it a few tries before I actually was satisfied with my images unlike my other one. The subtle drawback for me is the slow, automatic focus. It takes a while to lock on to your subject. Keep this in mind if you are shooting insects. Otherwise, plan on shooting in manual focus mode for optimal results.
Tamron 180mm f/3.5 Di LD IF Macro 1:1 SP AF review by dugong5pm
19 July 2014
Summary: an excellent alternative for the legendary Nikkor 200/4 Micro. It simply does the same, for a fraction of the price. IQ is superb. sharp even wide open. well performer for portraits too. build quality is nice. sturdy tripod collar, equipped with long plastic hood. One of the downside is the AF, well it's AF like a tamron lens. not really convenience for actions, but it's a macro lens, not really designed for sports anyway.
Summary: Solidly built,easy to use and excellent to capture those smaller live subjects without getting into there space. Does not scare away live critters because of the increase distance for macro use of lens. And can be used as a very sharp medium telephoto. Would recommend use with tripod. Minimal difference in picture quality with Canon 180 mm at 1/2 the price.
BE AWARE!! Not a constant F/3.5 aperture @ 1:1 Macro!! It's an F/5.6!!

Summary: While the Tamron 180mm "3.5" is in fact a great lightweight lens, with nice Bokeh, the lens automatically stops down (at least the Canon version that I purchased) to f/5.6 at 1:1 even in Manual Mode. I have older manual Macro lenses: Like a Proxitel 90MM 2.5 (1:1) Macro, and a 180MM 2.8 Sigma, and while the Sigma is very heavy and only does 1:2 "Macro" magnification, the aperture stays at a constant 2.8, all through the focus range, with maybe a small amount of fall off...
Summary: it has been my dream for a loooong time. finally tamron made it possible with great price & performance. lens is as good as nikon when it comes to sharpness. focusing a little bit slower & a great macro power!!! must to be in the kit. 3.5 at telepohoto & 5.6 at macro photo!!!
Excerpt: I am a lifetime amateur phtog. However, with the little time I have had avail. since purchase, this lens is outstanding. It beats my old 100mm by a long shot. I am very pleased with the results I have achiveed with my new 180.
Excerpt: I use this lens mostly for insects, especially dragonflies and butterflies. It produce sharp images. It is easy to switch from autofucus to manual; this is important to me because autofocus is usually only approximates the exact plane of focus I want - no fault of the lens, it's macro photography where one often needs to fine-tune focus. <br /><br />That said, autofocus is slow. It would also be nice to have stabilization.
Pros: Consistent Output, Durable, Easily Interchangeable, Strong Construction
