IMAGE QUALITY: Of course, the key requirement for each lens. Here the Tamron really can deliver: The sharpness is consistently good at open aperture and can be raised easily with the Nachschärfoptionen Lightroom or Photoshop. Details such as feathers or hair stand out clearly from its surroundings, which is accompanied by a surprising contrast basic impression of the image. From Aperture 8 sharpness over the entire zoom range can be classified as very good. From the sharpness ago I can make no difference to the Canon 100-400 - with the difference that a significant range bonus you get on top of the Tamron at the telephoto end. The lens vignetting very clear at maximum aperture and the focus falls particularly at the telephoto end toward the edge significantly. However, this is by no means dramatic, and certainly also due to the compact design and the relatively low price. In other words, the imaging performance is simply to specify the basic purchase price and just fantastic. It is certainly not the same at the level of the Canon-Teles with our coverage (600 or 200-400 4.0 4.0 with built-in 1.4x converter), which, given the price differential was around 10,000 (!) May not be surprising. However, as shown by numerous examples on the Internet now, you can expect excellent results when used correctly this lens. Even with Crop cameras (such as the Canon EOS 70D) is the Tamron on the resolution of problems realized what had given the smaller sensor area so to be expected (and therefore the higher requirement on the lens) for me.
AUTO FOCUS: With its ultrasonic autofocus and anytime rotating the focus ring Tamron makes basically everything right. For stationary motifs, the focus is almost always true, even though he can not always decide the same for one direction at targets in the distance. Here it helps to grip the lens with the wisely built scope terminator (15 meters to infinity) under the arms. The low intensity of 6.3 in the extreme telephoto range has a negative effect especially when automatic auto focus so rapidly flying birds are not really reliably detected. Who is documented in these moments to 400mm is limited (at this point the Tamron again reached a luminous intensity of 5.6) and well-lit situations, still may hope for good results. However, this requires very clear practice and experience, as one moves in the ultra telephoto in a boundary region, the long-time professionals had reserved with a corresponding budget. In any case, I noticed positively that the Tamron tends neither to a Canon EOS 70D, even at a 6D for front or back focus.
Image stabilizer: The image stabilizer will jump to a clearly visible in the viewfinder jerk and stops itself at 600mm the image relatively constant under control. Handheld shots are thus possible, which would have represented a small sensation a few years ago. Significant noise is not caused by the stabilizer there. From the hand of me are at the telephoto end yet succeeded sharp pictures at 1/125 second, which the stabilizer exhibits a very good report. However, on moving subjects (about birds) I try to be 1/1000 second to avoid motion blurring never slower than 1/500 or.
BOKEH: The appearance of the background blur falls unusually harmonious from a push. Nine aperture blades here make for a nice circle drawing itself structured troubled backgrounds reliable.
CONSTRUCTION QUALITY: You can tell the lens directly from the pack that of the tight budget, the maximum should be retrieved. Supplied therefore no quiver is well contained. Instead, put all the resources in the lens itself ("Made in China"), the lens hood ("Made in Philippines"), strictly speaking, only a piece of plastic without inner coating represents. For the Tamron but comes with a well-crafted Stativschelle that would tolerate at most a longer gripping surface for my taste. The Zoom runs surprisingly light and raises at least claim to be protected in some way against moisture. Although all kinds of plastic inserted in the external design, the lens looks valuable and well finished. Also, my copy properly centered, indicating low manufacturing tolerances.
CONCLUSION: A great lens, the relatively small and light fails for the offered focal length. If you have never worked with this kind of technique, they should however take into their own hands before buying one once: Almost two kilo are a value that not every user will be happy for a long time. Who takes this burden in buying and honing his technique, can tease out impressive results from the Tamron.
I hope to have you with an impression of the Tamron with this review. If you want to share your thoughts on the lens with me, I look forward to your comments!
