After delivery in prime Amazon style (evening ordered lunch delivered it), I have the lens once a detailed "(rapid) test" subjected in the garden. Bright midday sunlight supported hands-free food / macro photography with the shortest shooting distance (for the Auto Focus). In total about 150 shot shooting with differnet. Aperture (to test the depth of field), there were only about 10 focussing errors. This could even located on myself have (minimal movements when "shot" after focusing, or movement of the "object"). The autofocus is instantaneous, totally fail, in conjunction with the new Nikon D7100 is a remarkable attention to detail is even the finest details (not even visible to the naked eye when photographing the object were) to note (see above / the set of my photos on " bee on the flower).
Delivery, haptics etc have already been described in detail by other reviewers.
For me initially was confusing that apparently the maximum aperture of 1: 2.8 could not be set (Aperture Priority Mode, and Manual mode cpl.). Depending on the object / distance the adjustable aperture was at 3.5 / 3.0 to the end. At first I thought of a malfunction of the lens. A short email inquiry at Tamron (which was, incidentally, answered phone even after short about 30 minutes by a friendly and knowledgeable staff. Respect !!) was explained with that by design and only the lens group during focusing as much moves forward at close range that the amount of light is low, and the photometry of some newest cameras (correctly, as well as the Nikon D7100) this correctly in a higher aperture value display (you can read on the Tamron website at "FAQ's). Although other cameras show" Aperture 2.8 "to, but nevertheless extended (of course), the exposure time, the connection drops the" no user "there but" so "on In fact, the setting of the shutter 1 is in focus on distant objects then:. 2.8 possible and where appropriate . The confusion was resolved, there is no error in the lens In addition, you will For local / macro shooting most likely anyway and use the depth of field because of aperture values from about 8 up, and even at Bl 11 is the depth of field -.. macro conditionally - only least mm wide. Open aperture you will here eh not set but is in portrait photography as "exemption" of course possible. The beautiful bokeh this should be mentioned in any case. Absolutely soft and flowing in the most beautiful wonderful presentation.
I myself can the lens - the quality externally as well - and most importantly - subjective "100 points 100" award and am pleased to have decided on this lens - the for optical performance.
For me: in this price unbeatable quality!
I would again at any time buy.
PS: I have been photographing since about 30 years (formerly natural analog, with self-development of color and b / w photos), and would describe myself as a "semi-professional users."
