Optically it doesn't leave anything to be desired - the resolution is very good to excellent from f/3.5 all the way down to f/16 and vignetting, CAs and distortions are non-issues in field conditions. The bokeh (out-of-focus blur), a primary aspect in macro photography, is very smooth and buttery. The build quality of the Tamron is very good but there is one bug - the lens has no focus limiter and the rather slow AF combined with AF hunting can be a frequent and rather tiresome experience. Thanks to a focus clutch mechanism you can switch between AF and MF as easy as pushing/pulling the focus ring so if necessary you should give the AF a better hint by manual pre-focusing. Other than that it is a really impressive lens. ]]> Thu, 01 Apr 2010 10:30:40 +0200 123-187 http://www.fotofach.de/festbrennweiten-erfahrungsberichte/tamron-sp-af-180mm-f35-di-ld-if-makro-11/ The Tamron AF 180mm f/3.5 SP Di LD [IF] macro offers a near-flawless performance.
