Actually, I already knew exactly what I wanted: a bright telephoto lens, not too heavy, because I would usually use it without a tripod - so please also Image Stabilization - to afford I had to get me to, so an approximately mid-hundreds of price, it should have close to 300 mm and please also supply good pictures. And since then I also not only wanted a focal length for my field, forest and meadow Safaris, it had to be a decent zoom lens. In short, as I turned it and turned, "my" lens does not exist, there had to be a compromise - just the Tamron. 'M not a professional. Lichtstark it is not necessarily, but in my experience makes it with Aperture 6.3 at 270 mm and an overcast sky quite beautiful shots. The weight bothers me not one bit, not even the binding: As far as the part can be taken out by cars, have since probably already be some resistance, so it does not "slip" of itself. The wide-angle I use little and can not judge him. The images in the central region, I find measured mind that this is a superzoom, fine, and even at 270 mm I made very beautiful animal and plant shots. Above all, I'm so finally so close to wild birds approach that really good shots are possible. With my EOS 50D, I have noticed little of color fringes even in outer telephoto range. The distortions I also not serious. The reviewers who complain about rather low contrast, I have to agree with, but as a non-professional, I can still live well with this measure and, if necessary, perform image processing. The stabilizer is effective and useful, the bokeh beautiful, the lens overall quite handy. Unlike Canon lens hood is already included - great! This lens is a bit the "panacea" for aspiring amateur photographers who want a single lens for different applications: landscape, and the like as well as animals of almost any size, plants and portraits. For any individual application the optimal product, but it is a really good compromise!
