Very good performance for reasonable prices

I have gained this lens for the 400D due to his (expected) good price-performance ratio and its light weight. The cost point was almost 100. I am not disappointed: it forms in fact very well. The limitations due to the low light intensity to compensate the lens Although my opinion only partially with the image stabilizer because iris for me is also a creative instrument and not only "anti-shake". However, this makes for "everyday photography" no role for it was intended. The image stabilizer allows andererssits the creative use of Mitzieheffekten. In addition, it does not have to be additionally mentioned actually, of course, he works very well if 1/20 is no longer sufficient.
Technical and visually I can understand the rating on Photozone.de completely. The design is fine, but nothing compared to the more expensive lenses. My Tamron 17-50 2.8 acts valent of the materials here, however, is more than twice as heavy. A direct comparison of optical performance to show very large differences, apart from the edge design by aperture as already mentioned. the Tamron is maybe a bit sharper, but both lenses are nowhere near as sharp as the Tamron 28-75, selsbt with optimum aperture use.
Autofocus is not working particularly fast, but it was enough. Manual focusing is possible, but certainly not particularly desired by the designer.
CONCLUSION: a very good low-budget "Always plan" that does not need to hide. Highly suitable especially for beginners. Who something much better looking at Canon, probably need to grab 17-55 2.8, but the multiples costs.
